What can be done to waterproof brick walls?

Giving preference to brick as one of the most popular building materials, many novice builders forget that in this case, waterproofing of the brick wall is required. It will protect the structure from the accumulation of moisture from inside and outside the building. However, this process is fraught with many subtle points that every master should know about.

Required materials and tools

It is necessary to select materials for waterproofing using an integrated approach. Firstly, it is necessary to understand what type of waterproofing will be used and in what case. Thus, it is much easier to organize the process if the building is at the initial stage of construction, while waterproofing already dilapidated and moisture-damaged brickwork will be much more difficult.

Read how to lay bricks correctly in the article Bricklaying.

The second case will require not only specific equipment, but also special modern building materials that will block the old porous brick from gaining moisture from the outside. Such techniques are used primarily for the resuscitation of architectural monuments, but in domestic conditions, when the attractiveness of the facade and the peculiarities of the masonry can be neglected or hidden behind a pretty decor, relatively inexpensive building materials and affordable tools are quite applicable.

Not every method of waterproofing will be safe for the craftsman, therefore, for example, when working with an open fire, you should use not only the appropriate tools, but also protective equipment - non-flammable clothing.

A classic example of a material for waterproofing is bitumen and all its derivatives, but more modern ones include products based on synthetic resins.

Waterproofing a brick wall from the outside, what methods exist?

Brick is a common building material that has a porous (breathable) structure that is capable of absorbing moisture in the atmosphere, causing it to become damp over time. But such precipitation is unable to be absorbed by this building material as quickly as possible due to the fact that after a few seconds it evaporates into the air, but more severe natural conditions can cause quite serious harm to the brick.

This article will discuss in detail the waterproofing process, its types and features of the construction work being carried out.

Brick wall waterproofing process

Why do you need to waterproof a wall?

Waterproofing all walls is a fairly important stage in the construction of any building in order for the walls to last much longer, since their operational condition is negatively affected by weather conditions, precipitation and temperature changes.

Types of waterproofing

Waterproofing experts divide it into two types - carried out outside the walls and from the interior of the building. Based on this, appropriate materials are also selected, since the impact of moisture from the street is always more intense. Moreover, it can enter the brick not only from the atmosphere, but also from the soil on which the foundation of the brick house is located.

Based on their physical properties, insulating materials are divided into pasting, coating and impregnating. But since the latter are used extremely rarely due to the characteristics of the material being processed, we will consider the remaining two.

To carry out work on the front part of the walls, adhesive waterproofing is often used, and coating materials are used on the inside. They are represented on the building materials market by various mastics and similar bitumen-based plasters with various additives, including synthetic resins, polymers and even cement. Often they are not sold as a ready-made mixture, but in powder form, which must be mixed with a special liquid - latex water.

The main disadvantage of coating materials is their high cost; in comparison with them, coating materials are more attractive in price.

As for pasting materials, they are presented in three standard versions:

Sheet.Roll.Panel base.

They are also made using bitumen, but to obtain a more rigid base that is comfortable when working with large areas of brick walls, the base for them is:

paper; cardboard; fiberglass.

One of the varieties - roofing felt - is considered an inexpensive and quite effective option.

Waterproofing with profiled membrane

When considering materials for waterproofing walls from the inside of a room, you should pay attention to a profiled membrane, which has many advantages, among others, a long service life that reaches 50 years should be highlighted. In addition, the material is resistant to ultraviolet radiation, safe for the external environment, human health and retains elasticity when changing temperatures.

The membrane is non-corrosive and resists low damage and chemical elements.

This method of waterproofing is also good because it is economical, because you do not need to spend effort and money on concrete work. Installation is quite simple, so the work can be completed efficiently and quickly, especially during repairs. Waterproofing indoor walls with a membrane has one more nuance: films are more often used to eliminate excess moisture in basements. They are presented in the form of rolls. But if you want to carry out waterproofing work in a toilet, bath or shower, then it is better to use elastomer membranes in liquid form. The layer is durable and elastic, it has no seams, and is applied with a roller, brushes or in the form of a plaster mixture under tiles or gypsum panels. An example of a liquid membrane is ISOMAT SL 17.

Surface preparation

Regardless of which side you plan to waterproof a brick wall, it must be properly prepared, namely, remove dirt and dust, and also level the surface, leveling all chips, cracks and voids that may be present in the brickwork. This is necessary in order to ensure the best adhesion of the applied material to the surface being treated.

Before waterproofing, it is necessary to clean the brick wall. Read how to do this here.

To level brick walls, a lime-cement mixture diluted with plain water will be acceptable, but to make it easier to choose the right ratio of components, it is better to use a ready-made mixture from the trade and construction network.

However, there is a significant difference when working with coating materials and roll or sheet insulation.

If when working with mastics with the addition of cement walls do not require additional processing, then before gluing the rolls with bitumen they must be dried. You can use a wide variety of tools for this. The most effective in this case will be air heaters, fan heaters, including heat guns, as well as infrared heaters, which also do not heat the air in the room.

Waterproofing made from bitumen mastic lasts about 5–8 years.

Treating walls with antiseptic

Before applying antiseptic to the wall, it should be properly prepared. First of all, it is necessary to remove all finishing from the affected areas - old wallpaper, plaster, putty down to the bare wall.

Old finishing material contaminated with fungus should be disposed of in a trash bin, carefully collecting it. The fact is that fungal spores are very tenacious and, if construction waste is not properly disposed of, can again cause its development.

To remove the old finish, you can use any available tools: a spatula, a hammer, a chisel, an old hatchet, etc. To make old wallpaper come off easier, they should be thoroughly moistened with warm water and left for half an hour. We also completely dismantle and dispose of plaster permeated with mycelium.

After the wall is completely free of interior decoration, you should carefully inspect it. If it is damp to the touch, you will need to dry it thoroughly using a heat gun or hair dryer. Then these places are treated with chemical compounds with antifungal and antimicrobial components.

If you don’t have them at hand, you can make do with folk, time-tested remedies. This could be chlorine bleach or bleach. A solution of copper sulfate (20 grams per liter of water) or baking soda (1 tablespoon per half liter) is also suitable.

Application

Whatever the insulation is, internal or external, and whatever materials are used, it should be applied in several stages. Professionals recommend doing them with breaks, so-called technological breaks, which allow the insulating layer not only to dry out, but also to merge as much as possible with the previous layer or brickwork, as is the case with the initial surface treatment with insulating material.

When working, avoid rushing so that during the application process air does not accumulate in the middle layers in the form of bubbles, which, if operating conditions are violated, will not restrain the accumulation of moisture and in every possible way contribute to its accumulation.

Types of mold

There are several types of microorganisms and fungi that most often settle on wood. They differ in external characteristics, reproduction rate, toxicity of released products, and degree of deterioration of the material.

The most dangerous and aggressive type of mold is black mold, all strains of which multiply quickly, severely destroy wood, and can cause illness in humans. It is the most difficult to remove.

White types of mold can appear not only on wooden products, but also on food and various products. These fungi are removed faster and easier; they are less dangerous, although they can also cause irritation and allergies.

There are bluish types of mold that actively destroy wooden materials. They are especially dangerous for load-bearing structures, where they cause through-rotting. To remove them, the wooden surface must be cleaned mechanically and bleaches must be used.

Actinomycetes, bacteria similar in structure and properties to fungi, significantly worsen the performance characteristics of wood. When infected by these microorganisms, which appear primarily in places of high humidity, the softening of the material occurs very quickly. Infestation should be removed with strong antiseptics.

Waterproofing outside. Step-by-step instruction

A wall that has been completely dried from the outside, previously freed from decorative materials and all kinds of damage, is primed and re-dried. Then the brickwork is additionally heated so that the glued material instantly adheres to the primed surface.

The direction of laying the material is planned in advance and if horizontal laying was chosen, then it is not touched during the work so as not to change the direction of the fibers. If you plan to lay an additional layer of waterproofing, the laying direction is reversed.

Thus, if the first layer is laid horizontally, then the next one, fused onto it, must be laid vertically. Adjacent insulation sheets must overlap. On average, its size reaches 20 cm, but can vary depending on the know-how of the manufacturer.

Laying waterproofing on the street side of brick walls should be done in dry and warm weather.

When a layer of material is laid on the wall, excess air is removed from under it and, if necessary, the insulation is additionally heated using a burner to fuse the layer with the soil. The burners use propane and are equipped with torches to increase safety and comfort of operation.

Despite the fact that roll and sheet insulation are really popular, the use of coating materials for external treatment of walls can also be used, as well as inside a brick room.

Please note that it is not necessary to completely cover the entire surface of the wall with a layer of insulation. The height, and accordingly, the covered area, is calculated according to the project, based on regional characteristics, including the level of ground and groundwater.

How to waterproof walls from the inside?

Waterproofing is a necessary construction measure that ensures moisture resistance of building elements. To create a high-quality barrier that prevents water from penetrating inside, waterproofing is applied to the outer surface of walls and ceilings.

In cases where it is not possible to insulate from the outside, the moisture-retaining layer is installed from the inside. Waterproofing of walls from the inside is carried out in a basement structure, in a basement masonry, inside a bathroom in an apartment building, inside cemented containers for storing various liquids.

How to properly insulate brick walls from the inside? What materials provide the highest quality and moisture-resistant insulating layer?

Wall waterproofing scheme.

Waterproofing of walls and materials used

Materials used for internal insulation of brick walls can be divided into pasting, coating and impregnating.

The least high-quality and short-lived waterproofing is performed using lining materials (roofing felt, waterproofing, polyethylene). If, with external insulation, they somehow retain moisture, then with internal insulation, the adhesive insulation often falls off as a result of the adhesive mixture getting wet.

Waterproofing walls with coating materials is more durable and adheres better to the masonry surface. An example of such insulation would be liquid bitumen, moisture-resistant paint, which is applied with a brush or spray to the surface to be treated. In this case, the surface to be treated must be cleaned of dirt, grease and dried. Particles of debris or drops of moisture will become an obstacle to high-quality gluing. Coating insulation also includes plastering with a moisture-resistant mixture containing active additives that penetrate into concrete and brick and form a moisture-resistant barrier.

Waterproofing on a brick wall (from the inside).

Impregnating insulation today is the highest quality, reliable and durable. It is a dry mixture, which is dissolved during work and applied to the building surface with a brush. The mixture contains active additives that, when interacting with water, form insoluble crystals. The more water, the more crystals formed in the thickness of the main wall. If all the water is used up, the crystals stop growing and the thickness of the moisture-resistant layer stops increasing.

Waterproofing brick walls with a penetrating mixture is equally effective for both internal and external use. External impregnation stops moisture completely. With internal insulation, a water barrier is formed, located on the inside of the masonry. The outer layer of the masonry remains accessible to moisture penetration. When the outer layer gets wet, the active substances bind part of the calcium from the cement and form an additional water-resistant layer. The effect of “healing” cracks is based on this principle of action.

Due to the fact that the formation of moisture-resistant crystals occurs only in the presence of water, there is no need to thoroughly dry the surface before applying the coating.

Due to the formation of a layer of a certain thickness, the waterproof surface is not afraid of being scratched. Mechanical damage will not reduce the moisture resistance of the penetrating coating.

The main benefits of penetrating waterproofing for masonry are as follows:

1. Reliability and high quality of internal waterproofing.
2. Ease of application and manufacturability: drying of the surface is not necessary.
3. Possibility of covering from any accessible side of the building.
4. Resistance to mechanical damage and wear (scratches and abrasions are not harmful to the moisture-resistant layer of concrete or brick after treatment with active substances of the penetron group).
5. Self-healing of cracks.

Types of penetrating waterproofing

Waterproofing walls with penetrating additives can be carried out using various special mixtures offered on the market. The founders of penetrating insulation were mixtures of the “Penetron” group, produced for various applications: plastering, healing cracks, impregnating finished masonry. The essence of the action of all mixtures is the same - it is the creation of moisture-resistant crystals inside the base material.

Later, other competing mixtures appeared with the following names: “Kalmatron”, “Aquatron”, “Vandex”, “Xaypex”, “Lakhta”, “Polyfluid”.

Penetrating moisture-resistant insulation makes it possible to perform high-quality insulation of an underground structure from water from the inside. Other types of hydrobarriers do not have this advantage. Before the spread of penetrating building additives, high-quality insulation of walls and ceilings was possible only from the outside of their surfaces. To do this, it was often necessary to carry out extensive preparatory work: opening the foundation or basement located in the ground.

Active penetrating waterproofing allows you to cope with the necessary moisture-resistant insulation without digging up the soil, which greatly simplifies the work and reduces its cost.

Waterproofing from the inside. Step-by-step instruction

After careful preparation of the brick walls from the inside of the building, they begin to treat them with waterproofing mastics.

If necessary (this will be indicated in the instructions on the packaging with the material), the wall is heated and then coated. Use brushes or a roller for this. When choosing a brush, give preference to a painting tool with stiff artificial bristles.

Movements with a painting tool should be carried out strictly in one direction and as quickly as possible, until the bitumen composition has completely set, since it dries quite quickly under the right conditions.

In any case, one layer for effective protection against moisture will not be enough, so it is necessary to determine in advance the required amount of mastic that will be required to apply two or three layers.

Each subsequent layer is applied after the previous one has dried.

Waterproofing procedure

Most of these materials are applied to the wall using a paint brush or small spatula. The thickness of the layer must correspond to the recommendations in the instructions.

There are quite a large number of types of waterproofing, and each of them has its own subtleties.

For one method, one layer will be enough, while the other requires multi-layer processing. In this regard, it is necessary to carefully study the instructions that come with the insulator.

To apply a thick layer, the optimal tool is a rubber spatula. The sprayer can be used for liquid solutions or for applying a thin layer. Choosing the right tool will save you on material.

Post-processing

No matter how strange the following fact may seem, there is constant debate among craftsmen, both professionals and beginners, about when to carry out finishing plastering of brick walls - before or after waterproofing. At the same time, both sides of the debate are partly right.

On the one hand, not all waterproofing materials have an attractive appearance that can harmoniously fit into the interior, and on the other hand, if the waterproofing is located under a decorative layer, then it will not be able to fully perform its function and then you will have to get rid of the negative consequences.

Post-processing should begin only 24 hours after the insulating layer has completely dried, and after 7 days the walls will be ready to withstand active exposure to moisture.

Waterproofing methods

There are 2 ways: the walls are coated outside the house and/or inside. It is best to treat buildings immediately at the construction stage, since it is much more difficult to protect what has already been rebuilt. Varieties are selected depending on operating conditions and the desires of the home owner. Not all types have an attractive appearance, which will require finishing installation. Particular attention must be paid to the area of ​​application. It must be stated that brick can be treated.

The following types are used:

• coating;
• penetrating;
• injections;
• welded and pasted.

The first include various dry mixtures, paints and mastics. Each of them has its own characteristics. They are selected depending on the operating conditions of the walls, the amount of precipitation and the level of groundwater rise.

Dry mixes use cement as a base. The remaining components are chemically active reagents. Penetrating into the capillaries, the coating insulation forms crystals from inside the brick, which fill all the voids and prevent moisture from seeping inside. Even if damaged, the protective layer can repair itself. The crystals quickly grow again - the channel through which moisture previously penetrated will be completely blocked. These types are also called penetrating.

Benefits of penetrating agents:

• have a low cost;
• protect the base not only from the outside, but also at the depth of impregnation;
• long service life;
• a wide range of.

Fused types include types containing bitumen, for example, euroroofing felt. It is laid using a gas torch. The underside of the roll is heated and pressed against the surface, as a result of which it adheres tightly to the wall and protects it from rain or groundwater. But built-up waterproofing cannot be used for all types of brick. They are mounted only on fireproof blocks - red and fireclay.

Pasting options are laid on glue or mastic, or have a special self-adhesive layer. But they are rarely used for brick walls, since careful preparation of the surface is required. It must be absolutely flat, clean, and free of dust, otherwise the sticky side will not be able to adhere firmly enough to the base. Because of this, it will be necessary to treat the structure with deep penetration primers several times in order to significantly increase the degree of adhesion.

Injections are one of the most expensive methods. It is impossible to carry out such work on your own, since this requires special equipment and experience. Even a small error in injection technology can lead to serious problems that are subsequently very difficult to eliminate.

The bottom line is this: the composition penetrates into all kinds of voids: cracks, crevices, joints and pores. Injections can be made either inside the material or to fill the space between two structures. Waterproofing by injection not only protects against moisture, but also reinforces a wall or other structure.

Advice from professionals

The lack of waterproofing in brickwork leads to the formation of dampness and, as a result, to the appearance of mold and fungi, which provoke serious diseases. In addition, the accumulated water may contain salt, which destroys the brick from the inside, forming microcracks. And if there are metal parts in the masonry, they will also suffer from corrosion.

Read this article on how to make reinforced brickwork yourself.

The video at the link below shows an example of reanimating an old room with brick walls by using penetrating waterproofing.

Brick is a porous material that perfectly absorbs moisture.

Brick can be saturated with it from atmospheric air. But such moisture does not have time to penetrate deeply, since it evaporates almost immediately under the influence of sunlight and wind. The greatest danger is the direct contact of brick and soil.

The material, like a sponge, absorbs moisture, which can reach the upper floors of the building. This means that there will be a gradual destruction of the material, and dampness will be present in all rooms. Features of waterproofing brick walls Protecting brick walls from moisture should be done from the outside. Carrying out internal waterproofing work is devoid of practical meaning, moreover, it can increase the negative consequences. Creating internal protection will lead to even more intense saturation of bricks in direct contact with the ground with moisture.

Dampness on the upper floors will increase, and the building material itself will deteriorate. It is also necessary to waterproof the brick foundation or base from the outside. Therefore, such work should be carried out at the construction stage of the building. Instructions for insulating brickwork on video Types of waterproofing brickwork There are several ways to waterproof brick walls. For coating waterproofing, mastics based on bitumen with fillers or synthetic resins are used. An alternative to bitumen-containing coating materials are hard-elastic polymer-cement compositions.

Let's take a closer look at the modern two-component waterproofing mastic for brick and concrete Tekmadray Elast. It consists of a dry mixture dissolved in a latex water dispersion. The waterproofing material has excellent adhesion to the base.

Thanks to latex, it is able to bend and stretch significantly. Tekmadray elast is designed to create a separating waterproofing layer under ceramic tiles or other type of finishing coating. Such a waterproofing layer is capable of withstanding pull-off pressure reaching 5 atmospheres. Before waterproofing a brick wall, it must be thoroughly cleaned of dust and dirt.

To obtain an ideal result, a primer is applied to the wall before the main coating layer. The simplest, cheapest and fastest way to construct a waterproofing barrier for horizontal and vertical surfaces is to use adhesive waterproofing materials. Despite the difference in form - roll, sheet, panel - all these materials are based on fiberglass or cardboard impregnated with bitumen compounds. Adhesive waterproofing is most effective when used outside. Horizontal barriers work more efficiently than vertical ones. The most common representatives of this category of materials are roofing felt - roofing cardboard with a bitumen coating and roofing felt - cardboard impregnated with tar.

These materials are quickly installed and inexpensive, but they have a number of significant disadvantages that limit their use. The cardboard base does not withstand even minor mechanical stress and weakly resists rotting. Roofing felt on a fiberglass base is stronger and more durable, but also more expensive. An effective way to extend the service life of the roofing felt layer is to protect it with bulk cement mortar. The most common brands of adhesive waterproofing are TechnoNIKOL, Technoelast, Isoplast. Penetrating waterproofing, successfully used for treating concrete walls, not used for bricks.

Due to the low content of calcium and aluminum in it. The basis of plaster waterproofing is a solution based on sand and cement. It is not recommended to use cement of the lowest grades. Ensuring waterproofing of multi-layer wall structures with brick cladding Traditional technology for constructing thick brick walls is gradually becoming a thing of the past. Modern structures are multi-layered, and the brickwork acts as a cladding.

Behind the masonry there is a drainage cavity with a thickness of at least 50 mm, then - rolled or sheet waterproofing material, wood sheathing and a load-bearing frame. The main barrier to penetrating moisture is two layers of roofing material. The second layer duplicates the first in case of ruptures during the installation of a multilayer structure. In the areas of window blocks, metal ebbs are used to seal vulnerable areas. Sometimes, instead of metal flashings, in order to save money, developers use rolled waterproofing materials.

However, they are significantly inferior to metal in terms of durability and the ability to give the required shape. Brickwork seams are vulnerable to moisture penetration. Due to the difficulty of compacting cement mortar, the seams are sometimes not completely filled with it, which creates favorable conditions for water penetration. To create a waterproof masonry, the seams between the bricks must be completely filled with mortar, but the mortar itself must not fall into the drainage cavity and clog it. Ways to prevent channel clogging: A mesh is placed at the bottom of the drainage cavity, which catches debris, preventing it from falling down. Drainage the cavity must be at least 50 mm.

Otherwise, water can penetrate into the wood sheathing and then into the supporting structures. Incorrect choice of waterproofing material and violation of the technology for its use can lead to ineffective or ineffective expenditure of funds and labor. The need for proper waterproofing of a brick plinth The plinth is the lower, usually somewhat thickened part of the wall, located directly on the foundation. The foundation and base of the building are important not only as a support for the entire structure, but also as protection of brick walls from moisture. High-quality waterproofing of these structural elements protects the brickwork from moisture from the soil and atmospheric precipitation. For horizontal waterproofing, as a rule, roofing felt on bitumen mastic is used. It is laid in two levels - slightly above the level of the blind area and on top of the base.

For vertical waterproofing, coating or plaster compounds are most often used. Previously, only one waterproofing layer was laid - on top of the base. But this led to rapid destruction of the foundation surface. Especially during freezing-thawing.

Under the influence of external negative factors, brick walls are gradually destroyed, which leads to problems that arise indoors. The walls near the attic and foundation are especially in need of protection, because they are constantly exposed to moisture and precipitation that passes inside.

Over time, this leads to the appearance of fungus and mold, which negatively affects human health and the condition of structures. The main method of protecting surfaces is waterproofing a brick wall from the outside. For this purpose, today there is a huge variety of materials that are worth considering in more detail.

Insulation of brick structures from moisture ingress

To begin with, you should focus your attention on brick façade walls, since this is the material that is most popular in the construction of private houses and cottages. It is immediately worth noting that due to its porosity, brick absorbs moisture like a sponge, which is why structures without appropriate waterproofing can quickly collapse

This is especially true for walls that are located in close proximity to the ground or are in contact with it.

As a rule, the construction of the walls of a new building begins after the foundation is prepared. A layer of bedding or waterproofing is spread along the entire perimeter of the foundation; most often, ordinary roofing material is used for this, which is glued to molten bitumen. Only after completing the foundation insulation can you begin further laying brick walls.

The part of the walls that will be in contact with the ground, after backfilling, must be reliably insulated from possible penetration of moisture, otherwise the facade wall will not last long and significant damage may occur.

Here waterproofing can be done by two different methods, namely:

• pasting the wall that will be in contact with the ground with appropriate materials;
• waterproofing walls by coating with special compounds.

In this case, with the first option everything is more or less clear, but as for the second option, you will have to use the appropriate materials. Here, bitumen, bitumen-based mastic, rubber or synthetic resins can be used as waterproofing.

As a rule, the compositions are applied to the surface using a special sprayer, but renting such equipment can cost a lot of money, which is why they can be applied using a regular brush.

The application of such waterproofing is carried out in several stages, namely:

• first of all, the surface is cleaned of dust and accumulated dirt;
• Next, the brickwork is primed using a liquid solution - a mixture of gasoline and bitumen;
• After the primer layer has been applied, you can begin to apply the main waterproofing mixture using a brush or roller.

After the waterproofing work is completed, it is necessary to measure the thickness of the insulating layer, which should not be less than 2 millimeters. To do this, you can cut out a uniform piece of insulation and measure it with a micrometer; if you don’t have one, you can use a ruler.

Brickwork waterproofing work

Need for protection

Brick is a porous material, so when used in humid conditions, it becomes saturated with moisture, and a destructive process begins inside. The structure loses its integrity over time. You can protect structural elements from moisture using waterproofing.

This work is carried out in the area of ​​the plinth and external walls. Therefore, it is better to supplement the waterproofing of a brick wall with internal work. An integrated approach allows you to combat destruction throughout the entire service life.

Depending on the chosen type of protection, the algorithm for carrying out the work may be different. External waterproofing is usually carried out using fused materials, while internal work is carried out using coating agents.

The main feature of such work is the preliminary preparation of the bases, which must be smooth and dense for a good fit of the waterproofing layer. Preparation can be done using plaster based on lime-cement mortar. However, you can also use ready-made mixtures.

Types of insulation

Depending on the location of the insulation, three types of insulation are distinguished:

• external: the heat insulator is attached to the wall on the street side;
• in-wall: insulation is placed in a cavity inside the wall;
• internal: the material is attached to the wall on the room side.

At first glance, it may seem that there is not much difference between these methods, because the thermal resistances of all layers are summed up regardless of their relative position.

In fact, the position of the insulation relative to the main wall plays a very important role. If you attach it indoors, the brick or other material will be cut off from the warm space, which means that in winter it will freeze through.

Any material contains at least a small amount of water (add to this the steam coming from the room), so freeze-thaw cycles will quickly render it unusable. In addition, inside you will have to use insulation with less vapor permeability than brick, so the vapor permeability of the structure as a whole will decrease. Accordingly, ventilation performance will have to be increased, and along with it, heat loss will increase.

Thus, internal insulation should be resorted to only as a last resort, when external insulation is not possible.

As for intra-wall insulation, it allows the use of bulk materials, for example, slag or expanded clay. In this case, the outer part of the wall will not freeze much, since the above-mentioned heat insulators have a relatively high thermal conductivity coefficient.

Penetrating compounds

Penetrating waterproofing is quite common among professionals, which gives structures additional properties. When finishing a wall, modifiers are added to the solution, which penetrate the material through capillaries.

Among the advantages of such waterproofing of a brick wall from the outside, the following should be highlighted:

low cost of materials; the ability to protect external and internal surfaces; high levels of protection at the level of bitumen or film; wide range of materials offered; maximum penetration deep into the structure.

To protect the masonry from capillary suction, a method of restoring horizontal waterproofing is used - injection. This method is effective and widely used.

For horizontal waterproofing of a brick wall using the injection method, holes are made in the lower part of the structure in two rows, into which a special compound is injected. Materials with low viscosity and long curing times are ideal for these jobs. These mixtures fill the joints of the masonry and impregnate the pores of the brick.

When considering penetrating waterproofing mixtures, you can become more familiar with the Penetron composition. It is a dry mixture of cement, quartz sand and chemical additives.

"Penetron" is used to protect monolithic and prefabricated structures. With its help, it is possible to increase water resistance, frost resistance and strength. After completion of the work, the structure acquires the ability to undergo the following impacts:

sea ​​water; ground water; waste water; alkalis; acids.

Penetrating waterproofing for bricks

There are many situations in which penetrating waterproofing is simply irreplaceable when working with a brick base:

1. A shower or other wet area is finished or constructed with brick. In this case, the water pressure is positive, we carry out work on the side from which the water pressure comes. There is access to every area, and waterproofing bricks with penetrating compounds in this case is a real pleasure.
2. Penetrating waterproofing for bricks is indispensable when we are dealing with precast foundations. They often call us for advice and describe their foundation something like this: “The left wall is made of concrete, the right one is made of FBS blocks, and here, a 1x3 meter window is bricked up. A little more covered with homemade mortar and a couple of foam blocks.” Such foundations are often found in houses built in the 2000s and 1990s - during construction, those building materials that were available at the moment were chosen. For the sake of local waterproofing of a brick insert, no one wants to dig up the entire foundation; penetrating waterproofing comes to the rescue for bricks
3. Shut-off waterproofing is a type of waterproofing in which a barrier is created for further water leakage, most often horizontal. Thus, for example, the first line of brickwork installed on the ground will absorb water, but it will not rise higher, since water will be cut off along the second and third lines using the injection method; injection is an effective way to waterproof bricks.
4. External protection along the brickwork line. Quite often we come across structures with a monolithic foundation in the ground and brick walls above - the basement of the building. The depth of brick walls in this type of structure ranges from half a meter to three meters. They are installed on a concrete base and may not require horizontal cutting, but continue to suck in moisture from the upper soils with which they come into contact. In this case, penetrating waterproofing is applied to the brick from the outside, creating a barrier between the soil and the brick wall.

Work methodology

For waterproofing, you must follow a certain algorithm.

At the first stage, the surface is prepared, cleaned of solution residues and various contaminants. Next, the base is treated with a primer, which fills the pores and increases the protection of the material from mold and mildew. The surface is re-moistened, which is dictated by the characteristics of the brick.

Next, you can begin applying waterproofing using a spatula or brush. The solution is mixed and applied according to the instructions. The thickness of the applied layer may vary depending on the composition.

At the final stage, finishing is carried out. It may involve plastering the surface, but experts argue on this topic. Some believe that waterproofing must be applied to the finished finish, otherwise condensation, mildew and mold may occur.

Stages of work

Waterproofing a construction site with a penetrating mixture can be carried out both during the construction of the building and during major repairs or even during operation. When applying the composition, crystals form in the pores of the brick, thanks to which the ingress of water is reduced to zero.

Waterproofing bricks is carried out in several steps.

Careful preparation of walls, which are cleaned from oil stains, plaster, old paint, dust and dirt, in order to increase the penetrating ability of the composition. If there is mold, then before starting work, an antiseptic is applied to the walls.

1. Along the entire brick wall, specially shaped recesses are made at an angle of 45 degrees to the surface. Similar holes are made at a distance of 5 centimeters.
2. The recesses made in the wall are washed with water, as a rule, this is done using a high-pressure apparatus, and then filled with a penetrating composition.
3. Sealant is applied to the points where communication pipes enter.
4. The next stage is applying the composition to the walls (waterproofing masonry) using a brush.

When waterproofing bricks, you need to remember that you need to take a set of measures to protect the construction site from moisture. For example, if you do not protect the foundation, then treating walls with penetrating compounds will not achieve 100% reliability. Therefore, these works should be carried out by specialists, from design to complete completion of the process.

Methodology for carrying out work on applying coating waterproofing

The application of any waterproofing layer requires surface preparation. It includes cleaning the base from dirt and dust, as well as restoring the seams, if necessary.

The walls are covered with plaster, and then a waterproofing layer is applied with a hard brush, which allows you to get a smooth surface. It is smoothed out with a roller. At the final stage, finishing is carried out with facing material.

Waterproofing a brick wall from the outside from rain is often carried out using coating materials that have unique properties and proven quality. As an example, we can consider a product from German manufacturers, for example, Aquafin.

This composition is suitable for a wide range of works. After completing the application process, a day must pass for the material to become hard, then facing work can be carried out. After a week, the wall is ready for water loads.

In order to prevent the appearance of cracks on the surface, polymer-mineral waterproofing is used, which contains an elasticizer. This additive provides elasticity to the hardened layer, and in everyday life such compositions are called rubber concrete. The mixture is applied with a hard brush to a moistened surface, which allows you to obtain a seamless coating that covers cracks.

How to prevent dampness in the basement

If there is an accumulation of condensation on the outside or inside of the basement, leaks appear in the seams or the surface becomes damp, the following work must be carried out:

1. Disassemble the blind area around the entire perimeter of the building.
2. Carry out excavation work, namely dig a trench along the foundation wall.
3. Clean off the old waterproofing layer.
4. Waterproof the surface.
5. Make a backfill. Sand or clay is suitable for these purposes.
6. Build a new blind area.

Waterproofing the basement is a mandatory measure that allows you to protect brick basement walls from the negative effects of moisture and thereby increase the service life of a building or structure.

Using built-up waterproofing

Waterproofing a house in the area of ​​a brick wall can be carried out using fused materials. This protection involves the use of rolled materials that are attached to the base after thermal heating.

The work is carried out using the following technology: to ensure a tight fit of the insulation, the surface is covered with plaster, and then primed with bitumen mastic, which guarantees reliable adhesion. The strips are cut into separate sheets of the required length. They are then heated with a propane torch until bubbles appear on the material.

The insulation is glued to the surface. The strips must be attached without voids so that the material does not lag behind the wall.

Therefore, the waterproofing is smoothed with a roller or by hand during installation, and problem areas are cut out to make separate overlays for them. The strips are glued with an overlap, the width of which ranges from 10 to 15 cm. You should remember about personal protective equipment, because you are working with hot material.

External insulation technology

Step-by-step instructions for waterproofing a brick foundation or basement walls from the outside using weld-on rolls:

• The surface of the walls is cleaned of soil, greasy stains and old finishing materials, and left to dry.
• The base is checked for defects. Potholes are sealed with cement-sand mortar or other similar means, and protruding parts are removed. Before laying the composition, to increase the degree of adhesion, it is recommended to treat the surface with a deep penetration primer; it will strengthen the top layer of the brick.
• The height of the walls is measured. The roll is cut into the required lengths, all parts are rolled back.
• Place waterproofing on the foundation starting from the bottom and working towards the top.
• Installation is carried out as follows: the lower part of the roll is heated with a gas burner, after which it is slowly rolled out and pressed with a roller; there should be no bubbles.

If swelling appears, they are carefully opened with a sharp knife and the air is squeezed out. Then they are lubricated with mastic, heated and pressed. A patch can be fused for additional protection.

If the waterproofing of such a wall or foundation with fused or adhesive materials is carried out in several layers, then the joint points should not coincide. So, for example, the first layer can be laid horizontally, and the second vertically. All welded rolls are mounted with an overlap of 10-15 cm (this parameter depends on the manufacturer). For convenience, some manufacturers equip their products with special stripes indicating the width of the overlap.

The technology for applying the coating mixture is much simpler. Bitumen is often used for basements and plinths. It must be applied to a clean and dried surface; evenness in this case plays only a decorative role. Apply bitumen in 2-3 layers, the base must be absolutely dry and dust-free. To increase the degree of adhesion, it is better to treat the brick with a primer. If dry coating compounds are used, dilute them according to the manufacturer's instructions. You can place it either in a thin layer or in a thick layer, for example, 2 cm.

Insulation of walls from inside the building

Waterproofing the floor and walls of the basement helps protect the room from dampness and mold. Fused, coating or penetrating agents are used. The type depends on whether the house is under construction or just being renovated.

It is necessary to carefully select mixtures - they should not contain components that, when evaporated, can release dangerous compounds. Work is carried out at any time of the year. Before application, the surface is cleaned of old finishing, cracks and potholes are sealed. If the base will be treated with coating compounds, then it is necessary to coat everything with a primer to increase the degree of adhesion.

To protect basements and cellar walls built of brick from moisture, you can use lining and overlay types, as well as bitumen mastics. The following work is being carried out:

• A trench is dug around the foundation.
• The walls are cleared of soil and left to dry.
• The base is insulated.
• The trench is filled with sand or clay.
• The blind area is being laid.

Waterproofing is applied from inside buildings and in places where there is often high humidity, for example, in bathrooms or kitchens.

Before purchasing, you need to carefully check the manufacturer's instructions for compatibility with the building material from which the walls, basement or cellar are built. You cannot use fused rolls for finishing sand-lime brick, as it is not intended for high heat.

Also, the type of waterproofing depends on the level of groundwater rise; if it is low, one type can be used. It is enough to coat the walls with a penetrating agent. If the waters rise high, then several varieties are combined. For example, first the walls, cellar, foundation or basement are treated with a coating mixture, and then covered with rolled material in 2-3 layers.

You can treat surfaces with coating and penetrating mixtures yourself. It will be extremely difficult for one person to mount the rolls on a vertical base if he has not previously done anything like this. To administer injections, you must contact the appropriate company, as special equipment and experienced operators are required.

Using horizontal waterproofing

Horizontal waterproofing prevents the passage of water into the structure. It is represented by a layer that is laid on a horizontal surface, and a variety of materials can be used for this. Cement mortar or asphalt are suitable for brick walls.

After the masonry is erected to the design level, compacting substances are added to the mixture, with the help of which a layer of mortar up to 30 mm thick is created.

When using asphalt, this parameter is 20 mm, and the first row of bricks is laid exactly on this layer of mortar. A waterproofing layer based on roll materials is laid on a leveled surface, and the surface of the canvas is coated with bitumen mastic. At the next stage, you can continue laying.

Tips from the pros

When waterproofing a residential building, professionals advise using only proven materials that are of high quality, durability and reliability.

According to builders, it is best suited for internal waterproofing

• bitumen paste Elastopaz (“Elastopaz”);
• penetrating primer Flex (“Silpaz Flex”);
• liquid waterproofing Master Flex (“Master Flex”);
• coating mixture Styrbit 2000 (“Stirbit 2000”).

Waterproofing plaster type “Infiltron-100” and Izofol film have proven themselves very well.

See the following video for the process of waterproofing walls.

Pasted waterproofing from

Technonikol adhesive waterproofing is made on the basis of bitumen, which is mixed with atactic polypropylene or styrene-butadiene styrene. These additives are modified polymers, which makes the material more durable and strong.

TechnoNIKOL adhesive waterproofing is also created using vulcanized rubber, polyethylene and thermoplastic. The latter is made of polyvinyl chloride and chlorinated polyethylene, which are heated before use, and the seams are sealed by welding or using solvents.

Why is processing necessary?

Brickwork is used to create private houses and is popular due to its thermal insulation properties, environmental friendliness and moderate cost. But the material has a significant drawback: it is susceptible to moisture.

The lower part of the building and “wet” rooms inside the house are most susceptible to contact with moisture. The procedure for applying moisture protection is mandatory so that the walls can withstand atmospheric phenomena and temperature fluctuations. In addition to limiting the destructive effects of moisture, the waterproofing layer protects against steam and drying out of the brick as a result of evaporation of moisture from the walls.

Waterproofing can be applied both during construction and after its completion. It is recommended to carry out work on the facade of the building immediately, when the walls are just being erected.

What is the difference between the outside of a building and the inside?

To create reliable protection, materials with different properties are used, which are selected based on specific conditions. Different compositions are suitable for external and internal insulation from moisture.

External insulation protects:

• base;
• the lower part of the walls;
• external structural elements (porch, veranda);
• roofing

To protect the building from the outside, anti-pressure waterproofing is used; it protects against the ingress of moisture directed into the room.

The protective layer is applied on the outside of the wall. And if, for example, the water level rises due to precipitation at the base of the building, the waterproofing is pressed against the walls, protecting the basement from moisture.

Features of applying a protective layer on the outside of the building:

• not all products can be used due to direct exposure to sunlight;
• The air temperature must correspond to the recommendations on the composition.

Internal processing is used for:

1. bathrooms;
2. kitchens;
3. basements;
4. ground floor;
5. baths and saunas;
6. garage.

For processing, non-pressure waterproofing is chosen, which protects everything that is inside the room, starting with finishing materials. It helps to resist the accumulation of water at the base after spring floods, and prevents the penetration of water into the rough masonry during the operation of the building.

Requirements for waterproofing compounds used inside the building:

• environmentally friendly (without PVC, bitumen and rubber), non-allergenic;
• fireproof;
• thorough penetration along the entire perimeter of the room, particularly in the corners.

Waterproofing internal and external brick coverings differs in the method of implementation. Some types of compounds cannot be used outdoors or, conversely, in an enclosed space.

When to use both internal and external brick insulation:

• if the house is equipped with a brick base and there is a sauna, garage or kitchen on the ground floor;
• if the first floor of the house is on an uneven surface, the wall is on the leeward side, constantly getting wet due to precipitation, and there is a bathroom, kitchen or sauna inside;
• if the garage and bathhouse are separate, they are completely waterproofed inside, and outside at the base.

Above the lower part of the first floor of a residential building, it is not necessary to use both types at the same time; it is enough to protect the building from the inside.

Vapor barrier is applied only inside rooms exposed to steam: bathroom, kitchen, sauna, bathhouse, garage (if a hot wash is used).

Consequences of the absence of a waterproofing layer

What results from inattention to protecting bricks from moisture:

1. 
   The porous material is saturated with moisture, small particles are washed out, and the structure is damaged. Parts of the cladding break off and crumbs appear inside the premises.

2. When exposed to the sun or exposed to high temperatures, the brick dries out and cracks. The structure is deformed and collapses.
3. The lower floors of the house are constantly damp, high humidity, and cold. The floor freezes, requiring large heating costs.
4. In a humid environment, microorganisms that are hazardous to health, such as mold and mildew, multiply. They are almost impossible to breed, they multiply quickly and worsen the quality of life.
5. Without waterproofing, insulation cannot be installed. Otherwise, the technology will not be followed and the wet material will cease to fulfill its purpose.
6. Along with water, salts penetrate into the brick, leaving a white mark and damaging the façade. With the onset of cold weather, the moisture inside the material freezes and increases in size, creating pressure on the form, tearing the brick.

Consequences occur both outside the building and inside. Therefore, it is important to follow the technology and use only high-quality materials that are suitable for protecting a specific element of the structure.

The most common penetrating materials for protecting a brick wall

If deep penetration waterproofing is used, the surface will become insensitive not only to water, but also to the influence of solvents, petroleum products and alkali. The construction market is full of products that protect brick walls. Here is a list of the most common ones:

1. "Khureh." Made in Canada. Waterproofing is based on cement. It has active additives. Thanks to them, water will not penetrate into the structure of the material. In addition, they perform a protective function, since the wall becomes invulnerable to the effects of chlorides and corrosion. The principle of operation is simple: active additives pass into the pores, after which an insoluble compound is created. When the substance comes into contact with water, a crystalline structure is formed. Such compounds in the concrete mixture make it absolutely protected from external influences and moisture.
2. Isomat Aquamat. Representative of coating-type waterproofing products that penetrate the structure. Most often used as a protective layer against water in swimming pools, wells and other similar structures. Product advantages: the composition is constantly in active condition after use, surfaces receive maximum moisture protection, structural elements are less vulnerable to mechanical damage, and the fittings are not afraid of corrosion. The product can be used in structures and containers used to supply drinking water.
3. "Penetron". The product is made on the basis of quartz sand and cement (a special brand is used). Additionally, the raw materials are mixed with active substances. The product is intended for waterproofing work on reinforced concrete and other materials that have cracks no more than 0.4 mm wide. Penetron is also used to process brickwork, plaster and concrete structures made from a sand-cement mixture. The substance is applied both from the outside of the walls of the house and from the inside. It is environmentally friendly, it can be applied with a brush even on a damp surface; after crystallization, moisture will not penetrate up to 1 m deep.
4. "Virtyoz". Penetrating type waterproofing for treating walls inside and outside. The packaging contains cooking instructions. This is a kind of waterproofing plaster, which, after mixing, is applied with a spatula or brush to the brickwork or concrete surface. After application, it is recommended to moisturize the surface for 3 days.
5. "Waterplug." This is a dry mixture consisting of aluminate cement, quartz sand and active additives. With its help, it is easy to eliminate pressure leaks that form in concrete or brick structures. Feature: quick setting, ability to expand. The material is used together with Penetron. The product is environmentally friendly and therefore suitable for structures that provide water supply.

To summarize, we can say that waterproofing bricks with deep penetration means has a lot of advantages. They are affordable, easy to use, environmentally friendly and, most importantly, can be used on an already erected structure. The brick surface and masonry will be reliably protected, and the penetrating properties allow the products to be used even on double silicate bricks.

Important! It should be borne in mind that such waterproofing is universal and will help achieve complete protection. If it copes with the walls, then it is better to additionally protect the foundation with horizontal insulation. For maximum effect.

Methods of protection against moisture and mold

Not all types of waterproofing are suitable for brick structures. Let's take a closer look at those that have the necessary properties and are recommended for use by experienced builders.

Injection

The technology makes it possible to create high-quality protection in parts of buildings that are below ground level. Used after completion of construction, in old buildings, when repairing existing waterproofing of a different type. Helps protect against water, rain entering the masonry through capillaries (microcracks), from the soil or the atmosphere.

To form waterproofing, a water repellent and high pressure pumps are used. The essence of the process: the composition penetrates the capillaries of the brick and crystallizes inside, pushing out moisture.

Advantages of the method:

• the building material itself does not change its properties during the process; on the contrary, the heat and sound insulation capabilities are improved;
• in addition to moisture, the composition prevents the penetration of any liquid substances: petroleum products, alkalis, solvents;
• economical investment, does not require repairs, works well.

Minuses:

• the wall is partially processed, it is impossible to track to what depth the composition has penetrated;
• requires the involvement of specialists and equipment;
• expensive material.

They are used more often for external processing, for repairs and improvements inside the building.

What are the mixtures made of:

1. Polyurethane polymer gel. An inexpensive and effective way to effectively close capillaries from moisture, it interacts with water and increases in size by 20 times.
2. Epoxy based. It hardens in the open air and is used on finished, completely dry structures.
3. On acrylic acids. Acrylate compounds quickly harden inside the brick. Can be used on the outside of the wall under the ground. When connected to the soil they become stronger. Their density coincides with the density of water, penetration into the capillaries is as easy as possible.
4. Cement-sand. In addition to waterproofing properties, they seal cracks and seal walls from the inside.

Additional properties of injection waterproofing: destruction of foci of fungus, preventing the spread of mold, improving protection against chemicals and preventing corrosion of reinforcement.

Pasting

The essence of the method: a waterproof continuous coating is created from a multilayer material, which is fixed to the object using a special adhesive composition. This type of waterproofing is sold in rolls and is called roll insulation.

What does it consist of:

• Adhesive base. It is not always present on the protective sheet, but greatly simplifies the installation process.
• Substrate. It consists of polymer materials and is used as a frame for a waterproofing layer.
• Waterproofing layer. Located on the front side of the cut, it protects the wall surface from moisture, contains bitumen or similar materials with zero permeability.

The adhesive waterproofing is applied in a continuous layer, the material is overlapped, and the joints are carefully insulated.

This type of waterproofing combines with vapor barrier and insulation and is considered the most popular.

Advantages:

1. Availability. Low price, you can buy it at any construction site.
2. Safety. They are manufactured according to state standards and do not contain harmful substances (except for some varieties that are not recommended for use inside a building).
3. Coating stability. It is most often used on the outside of a building; it can withstand the passage of groundwater and heavy rainfall. Some species are adapted for extreme conditions.
4. Easy installation. For pasting, no additional equipment is required; all manipulations can be carried out with your own hands. The coating applies to both vertical and horizontal surfaces.

Flaws:

• Almost all wrapping materials are flammable, so they are rarely used inside a building. In the technology of melting joints, a gas burner is used, which must be handled with the utmost care.
• The surface must be straight and level, then the pasting will adhere tightly. For passages, windows and pipe outlets, you will need holes in the material and additional waterproofing in this place using a different kind of material.
• Some types of roll waterproofing have a short service life and will require repairs. They are subject to mechanical damage, so the surface must be smooth.

There are rolls, sheets and tiles. The varieties include:

• Ruberoid. The composition is based on cardboard-based bitumen substances, the most popular and inexpensive option.
• Hydroisol. There are varieties made from fiberglass. Another option: asbestos based on bitumen mastic.
• Isol. Contains only bitumen and rubber. Suitable for underground use.
• Glass insulation Similar to waterproofing, only a protective layer of polymer materials is added.

For brick walls on the outside, vertical type waterproofing with abrasive powder is suitable. For interior spaces, it is recommended to use polymer protection. If additional strength is required, choose fiberglass-reinforced sheeting.

Smearing

This method is used for external and internal walls; it is an effective way to prevent capillary moisture from passing through and can withstand water under pressure (ground, precipitation).

Varieties:

1. 
   Bitumen based .
   Advantages: dense coating, the entire surface is protected without seams, elastic layer, affordable price, can be applied independently, without the use of additional equipment. Disadvantages: service life on average 6 years, requires repairs, may crack due to building movements. Working with bitumen requires heating and there is a fire hazard.

2. Mastics with polymers , latex or rubber as a base. Pros: they are more elastic, firmly adhere to the surface, and can be used in rooms where the temperature changes. Disadvantage: the cost is higher.
3. Cement based. Pros: effective protection not only from moisture, but also from destruction, ease of use, long service life. The material is environmentally friendly and safe.

Polymer mastics are mixed with a special emulsion, bitumen and cement materials - with water.

The coating is used mainly for interior spaces; it perfectly follows the shape, levels the surface and is completely safe for humans. An excellent option for bathrooms, kitchens, swimming pools, steam rooms.

Vapor barrier

It is used indoors, where the temperature changes and wet drops settle on the walls (bathrooms, bathhouses, garages, kitchens).

For protection use:

• plastic film;
• liquid rubber;
• foil steam-hydro-thermal insulation;
• bitumen-based materials (glassine, roofing felt);
• isospan, magaisol;
• polyurethane foam.

It is applied as the last layer before finishing. Often used in conjunction with injection waterproofing.

Advantages of waterproofing materials

This treatment has many strong points. These include:

1. The cost of penetrating waterproofing is low compared to competitors, and finishing the wall from the outside will cost much less.
2. The high level of penetration of the material will provide protection not only for the surface, but also for the base.
3. The moisture-repellent characteristics are in no way inferior to film or bitumen, but experts still advise not to use such material for external protection of the foundation.
4. Good indicators of deep penetration into the structure allow the use of such products even on sand-lime brick, significantly increasing its protection from moisture.
5. A wide variety of such materials will allow you to choose an option that is ideal for processing a particular surface.

Keep in mind that for effective protection it is better to combine such material with other insulators. This will allow you to achieve maximum efficiency. For more information about penetrating waterproofing, watch this video:

As you can see, waterproofing brickwork using modern materials allows you to achieve a good level of protection. The main thing is to take into account the properties of a particular surface. The processing procedure is quite simple and even a beginner in the construction craft can handle it.

Why protect brick walls from moisture?

Waterproofing walls and foundations is an integral part of construction work, which is carried out during the construction of buildings. Thanks to this, the walls will be less susceptible to negative factors such as precipitation and strong temperature fluctuations. After all, if the structure is unprotected from moisture, it will gradually deteriorate, cracks and deformations will begin to appear. This is especially true for buildings located in humid regions.

The word waterproofing itself consists of two parts: “hydro,” which translates as water, and “insulation.” That is, waterproofing is a process that allows you to protect or isolate a particular material from the negative effects of moisture. There are several rooms in the house that constantly have high humidity. We are talking about the kitchen, bathroom, garage, basement, bathhouse or sauna. If necessary, it is possible to carry out waterproofing work separately for a specific room. Or start building it from the outside. In this case, waterproofing the external walls allows you to protect the house completely.

So, without a waterproofing layer, the walls will be vulnerable to the negative influence of moisture; not only will the structure begin to deteriorate, but water will constantly penetrate inside. For example, during heavy rain, there is a possibility of flooding in the basement or garage. The waterproofing layer of a brick wall serves as a barrier that does not allow moisture to pass through. There will be no “crying walls” effect inside, and the humidity level inside will be optimal. As a result, the surface of the walls will not become covered with fungus or mold.

It is advisable that waterproofing of the external walls of the house is carried out at the stage of their construction. Protecting the walls of an already built house will be more expensive and more difficult to implement. There are many materials on the construction market for these purposes: mastics, penetrating waterproofing for bricks, rolled materials, injection pastes. They are different and have their own characteristics. Thanks to them, you can protect the structure both outside and inside.

Waterproofing under the cladding

You can create high-quality waterproofing of the foundation at the time of cladding the house. Professional builders warn that if you want to cover a house with siding or similar material, which should have a gap from the wall, then take care of thermal insulation and waterproofing material.

In the case of screeding the base with a waterproofing agent, proceed from your own capabilities and requirements. In stores you can find a film or a special membrane that will help to properly tighten everything.

When the heat and waterproofing have been selected, we proceed to installation. First, we use insulation, which will protect the foundation. And only then we isolate it from moisture. This is the only way you can protect the walls of your house.
