How to protect the walls of your house from moisture. Protecting walls from moisture. The need for internal waterproofing

High humidity is typical for many houses, garages and other buildings. Such buildings are always quite damp and uncomfortable. The reason for this lies in elevated level humidity. Improperly performed waterproofing of walls from the inside against mold can lead to a number of very negative consequences. The most significant thing is that living in a damp room can negatively affect the health of the people living in it.

Protecting the walls from the outside

The best results can be achieved when performing work not only on the internal areas of the facility, but also on external areas. However, it must be taken into account that it is advisable to carry out external waterproofing during the construction of the facility. In this case, the walls and roof must be waterproofed. To do this, it is necessary to provide for a certain set of works at the design stage of a house under construction. In this case, you can choose the pasting, painting, coating method, or perform asphalt or rigid waterproofing.

Painting waterproofing will be a reliable barrier to capillary moisture. Petroleum bitumen and other mastics are used for this purpose. They are applied in two to four layers. In this case, the thickness of the formed layer can reach 6 cm. In this case, the corners and edges of the protected surface must be sealed with strips of waterproofing or glass mesh.

If you are waterproofing walls with your own hands, then you should pay attention to the coating method. It involves the use of special compounds, which are applied in a continuous layer having a thickness of about 5 mm. To ensure rigid waterproofing, a solution based on sand and cement is used. This best option for waterproofing the basement of the house.

The creation of an adhesive hydrobarrier is carried out in the following sequence:

the bitumen layer is being installed;
the walls are covered with two layers pasting materials. Adhesive composition stands bitumen mastic. It is necessary to use special lining materials roll materials: insulation, glass felt, waterproofing and other materials that are resistant to rotting. For this reason, you should avoid using roofing felt or glassine;
coating materials are applied. There should be no swelling or peeling on the surface of the materials. In this case, a reliable barrier will be created in the path of moisture.

Asphalt waterproofing involves applying an asphalt mass about 15 mm thick to horizontal and inclined surfaces of the basement. Asphalt waterproofing is produced by emulsion mastics that contain cement. Asphalt mastics can be applied hot or cold. At the same time, the former begin to fully provide water protection after complete drying, and the latter begin to cool down.

Otherwise, excavation of the foundation will be required to achieve the best result. This will require additional financial investments. Therefore, if the waterproofing of the walls outside was not carried out during the construction of the house, the work will need to be done indoors. In this case, you need to choose the most suitable option.

How can you protect walls from moisture from the inside?

Protecting walls from the inside

First you need to decide on the type of material used. The sequence of work will directly depend on this. In this case, all materials can be divided into compositions:

penetrating action;
based on expanding cements;
which are based on the principle of waterproofing membranes.

The first group of materials forms a crystallization barrier in the wall, thereby dramatically increasing its water resistance. Such compositions, after adding water, take on the appearance of a liquid dough. They are applied to a damp wall, ensuring the formation of a thin hardened film on the surface. Materials of this group are able to penetrate 15 cm deep into the structure, leaving the capillaries permeable to air. Such compositions are sometimes called penetrating.

The second group of compositions is relevant when it is necessary to impart water resistance, crack resistance and durability to structures. They have a high degree of adhesion to old concrete. This is relevant in the case of creating a water barrier inside an old building. Can be used for underground and above-ground structures.

In addition to those mentioned, you can use roll materials - polymer films. They perfect option when using insulation in the form of slabs. If waterproofing indoor walls is carried out with their help, then the sequence of work is as follows:

the polymer film is fixed;
insulation is being installed.

If necessary, you can also use cement-sand mortar, into which various additives are introduced to provide the required set of properties. This plaster must be applied in three stages. In this case, the primer is applied first, and then subsequent layers. In this case, each layer can be applied only after the previous one has hardened. In this case, a dense crust will be formed, which will not allow moisture to penetrate inside for a minimum of financial investment.

We create a hydrobarrier with penetrating materials

These materials can be used to waterproof basement walls from the inside, as well as any other room. With the right composition, a leak can be eliminated in a fairly short period of time. Penetrating compounds can be used both in the construction of new facilities and in the repair of facilities that have been put into operation for a long time. At the same time, you can protect walls that were made using concrete, stone, or brick.

Protecting the walls in the basement from the inside

The sequence of work in this case is as follows:

the walls are thoroughly cleaned;
the required amount of water is added to the composition consisting of cement, sand, modifiers;
the surface of the protected wall is moistened with water;
the composition is applied to the wall in a thin layer.

The material, penetrating inside the wall, comes into contact with the water that is inside the wall. In this case, the composition, passing through the existing capillaries, clogs them with the resulting crystals. As a result, a fairly reliable hydrobarrier is formed that can withstand exposure to moisture for a long time. Work can be done indoors at any time of the year. It is important that the temperature corresponds to the recommended value.

Waterproofing basement walls performed using this method has the following advantages:

can be applied to the opposite side in relation to a surface that is unable to retain moisture;
allows waterproofing to be carried out after all construction work is completed;
does not require mechanical protection;
high fire resistance and chemical resistance;
significant durability;
possibility of choosing foreign and domestic compositions.

In addition, it is worth noting:

If panels were used during the construction of the house, then when creating a water barrier it is necessary not only to protect the walls, but also the joints between the plates;
Creating reliable waterproofing should be taken care of even at the design stage of a house under construction, and the entire necessary range of work should be completed in advance;
If you are waterproofing walls in a bathroom, kitchen, or sauna, then it is better to give preference to penetrating waterproofing;
Waterproofing must be continuous. Particular attention should be paid to the seams located at the junctions between wall and wall and wall and floor;
Preference should be given to modern high-quality materials.

Currently, such an industry is developing at a rapid pace in Russia. National economy like construction. Hundreds are being built every day various buildings and structures. Basic construction material, which is used for this is a brick. Very often, problems with brick laying arise for private owners. This manifests itself in the fact that brick structures begin to collapse. This occurs mainly as a result of moisture getting between the bricks, in the joints or seams. In this case, moisture is deposited, and in winter time and freezes, destroying the structure from the inside. Externally, this process manifests itself the following signs: visible cracks on the walls, between the seams, a decrease in the heat-insulating properties of the enclosing structures, the presence of moldy fungi, greenery, and so on.

It is necessary to protect the brickwork and eliminate negative impacts moisture on the brick.

Some owners, seeing this, begin to insulate their homes from the inside, but this does not solve the main problem. The structure gradually collapses and becomes less durable. As a result, you will have to resort to expensive repairs. It is best to prevent these negative effects of moisture on brick. Let us consider in more detail how and with what help protection from moisture is carried out, the main reasons for how brick protection is carried out.

Masonry repair options

Protecting a brick wall from moisture includes hydrophobic impregnation of the wall and cleaning the surface.

Protection brickwork from water - this is a rather serious problem. It is best to do this at the construction stage, when the damaging factor is not yet in effect. But if, nevertheless, there are already visible signs of destruction and exposure to moisture, then there are 2 main repair options. The first one, if the seams are in in good condition. In this case, hydrophobic impregnation of the wall is used, as a result of which water and other liquid substances do not affect it. In the second case, the seams are sealed first, and only then water-repellent substances are used. Protecting a brick wall from moisture should include periodic inspections and cleaning of the surface.

Inspection is carried out at least once a year. At the same time, visible dirt is removed, greenery and mold are removed. All this does not have to be done manually. There are special devices, for example, a cleaner high pressure. This very useful device in the household is capable of cleaning any surface from chemical and mechanical contaminants. It can be used to clean cars, remove old paint. If the dirt cannot be removed, you can use a special paste.

Sealing joints between bricks

Protection is also carried out by cleaning the seams between them. During the work, the crumbling elements of the mortar between the bricks are removed. Facing stones that are in unsatisfactory condition are also removed. The seams are filled with cement-sand mortar and then sealed with a special substance. For these purposes, it is recommended to use the following solutions: Atlas, Betonite and others. It is best to apply the solution not separately to each seam, but to the entire surface to give it greater stability and strength.

The stages of work include: removing destroyed mortar and bricks, pre-impregnating the wall, waiting for it to dry, then sealing the seams, cleaning it and impregnating it a second time.

To seal the joints, it is necessary to prepare a mixture based on cement and sand. The solution is rubbed into the wall using a special board with rubber. After this the wall is washed clean water. It is important that after this stage the surface is protected from direct sunlight. After 2 days, the impregnation is repeated.

Impregnation of a brick wall

After impregnation of the wall with hydrophobic substances, a protective film is created that does not collapse for a long time.

Protection of brickwork can be carried out in other ways. Even if the walls are saturated with moisture, it is recommended to impregnate them with hydrophobic substances. It is advisable to do this in dry, warm weather so that the solution is well absorbed. The essence of this method is that the substance included in the preparation helps close pores in the building material (in the seams and the stone itself). At the same time, an invisible, transparent, thin protective film is created on the surface of the structure, which does not collapse for a long time. Impregnation is best done before sealing joints. For convenience, use a sprayer.

The drug is applied from top to bottom. Previously, the domestic drug Siloxyl was widely used, but now its European analogue Funkosil is very popular. They are very easy to use, as they are very active even on wet surfaces. It is environmentally friendly, therefore practically safe for the human body. Despite all its advantages, the substance will not last long. Will need to be repeated periodically this procedure to avoid repeated destruction of the brick.

Efflorescence on the surface of a brick

Efflorescence on the surface of the brick indicates an active process of destruction of the wall.

Brick is ceramic product, which does not contain any salts. Even if there is a dye (metal oxides) on its surface, the salts cannot come to the surface with water. Salts give it color. In white brick there are none at all. Salt is formed from a solution that is used in masonry. This stone contains many pores that absorb both moisture and salts. After the water evaporates, you can see a white coating on the surface, this is efflorescence. To a greater extent it worsens appearance designs, but this is not the main problem. Salts indicate an active process of destruction of the wall.

The most commonly used product for removing efflorescence is Decap’ sols Guard. Before applying it you will need some preparatory work: check the quality of waterproofing, especially the roof and gutters, and reduce moisture ingress. You will also need to clean the seams. There are other similar active substances, but their mechanism of action is the same. Some of them do not require neutralization.

Water repellent Kristallizol

The water repellent Kristallizol is very economical and easy to use.

Protecting brickwork from liquid can be done using special substances. The most effective of them are water repellents. What is it? This is a product that is used for water-repellent impregnation for various construction work. It is a silicon-based concentrate. This is a perfect and multi-component drug. Experts recommend it for processing artificial stone, concrete, brick, ceramic tiles. Unlike its other competitors, it is active against wet surfaces of structures, which gives it wider use and greater effectiveness.

Found a similar concentrate wide application in the processing of slate, brick, concrete, shell rock, cinder blocks, gypsum, plaster and other materials. Its scope is very large. Its advantage is that even in the presence of moisture, it is very economical, unlike its foreign counterparts. It is diluted approximately 30 times, so one liter of the substance is enough to treat more than 150 meters of the surface of any material. Cost of processing 1 sq. meters is only 12.5 rubles. Therefore, Kristallizol is practically indispensable in this area.

Mechanism of action of Crystallisol

Crystallisol prevents the deposition of dirt, moldy fungi and the penetration of moisture deep into the coating.

Protecting brickwork in this way is that the water repellent helps to increase frost resistance brick construction several times, in addition, its strength increases by 24 - 26%. Very often the product is used in cladding the surfaces of buildings with high humidity

: baths, saunas. In this case, Crystallisol prevents the penetration of moisture deep into the coating and prevents the deposition of harmful microorganisms, in particular microscopic moldy fungi, on the surface. They can be used to process facades. Crystallisol prevents the deposition of dirt on the surface of the brick, which has a beneficial effect on the aesthetic characteristics of the building or structure. Along with these beneficial properties

, the product is widely used for painting walls along with conventional paints. Thanks to it, it is possible to reduce the amount of paint consumed and save a little. Another big advantage is the ease of use. This does not require special knowledge, skills or equipment.

Advantages of Kristallizol: the drug is environmentally friendly, fireproof, durable, does not change the appearance of the surface.

As mentioned above, this method is very simple, effective and economical. It has a number of advantages over other means of protection. Firstly, the water repellent does not create a visible, sticky film on the wall surface, which would cause the accumulation of dust and dirt. Secondly, this drug is environmentally friendly. This means that it contains no harmful chemical substances, dangerous to humans. Thirdly, it is fireproof, unlike regular paint. Fourthly, it does not change the appearance of the treated surface and does not interfere with the vapor permeability of facades. Fifthly, it's cheap. Sixth, it is durable.

The impregnation contains no solvents that can be toxic. It is economical, that is, it is used only in diluted form. Its dilution ratio to water is 1:30. Consumption rate per 1 sq. m is 200 g of solution. Thus, one liter of the drug can treat more than 150 square meters. meters of surface. It is also important that it is active on almost any surface, be it brick or concrete.

Instructions for use

To protect the brickwork from moisture, it is necessary to prepare a working solution.

Protecting masonry requires knowledge of the description of the product, area of application, and preparation of the working solution. In order to prevent exposure to moisture, you will need to make a working solution. To do this, the substance is diluted in ordinary water in a ratio of 1:30, after which the resulting mixture is applied in an even layer to the surface of the brickwork. It is important that it is clean and dry. If it is contaminated with efflorescence, fungi, or herbs, then you first need to clean it. For this it is best to use chemical solutions and antiseptics, which have disinfecting effects and remove biological agents from the surface. It is advisable to remove mechanical contamination with a jet of water.

On facades brick buildings The water repellent is applied in a thin, even layer. There should be one layer. On concrete coverings It is possible to apply a double layer, with a gap between them of at least 10 - 15 minutes. It is recommended to do the treatment in dry, warm weather at a temperature of at least + 5 degrees, otherwise the effect of protection against moisture may be lower. If you follow the instructions and proper care behind the surface of brickwork, the validity period of the drug Crystallizol will be from 10 to 12 years. This substance is also an excellent antiseptic that prevents the formation of harmful mold on the surface of the masonry.

The water repellent Crystalizol is applied to the facades of brick buildings in a thin, even layer.

We can conclude that very often in private construction there is destruction of structures, including brick ones. The main reason is exposure to moisture and lack of pre-treatment of the surface with protective agents. Moisture penetrates the seams and pores of the brick, gradually destroying them. There are 2 main repair methods. In the first case it is required pre-cleaning and removal of damaged material, then impregnation. In the second, the walls are simply treated with active substances. In order to make repairs, you will need equipment and tools:

Master OK;
falcon;
sledgehammer;
cement-sand mixture;
shoulder blade;
ladder;
hydrophobic solution;
hammer;
solution container;
wooden stick for even application of the product;
water hose;
antiseptics;
sprayer.

Very popular today are water repellents that can form on the surface of brickwork. protective film. It is simple, economical and very effective method protection from moisture. When carrying out all work, it is very important to follow the instructions for its use. Very great importance It also matters whether you noticed the first signs of destruction in time or not. Very often, the first symptoms of masonry destruction are the appearance of efflorescence on the surface, which represents white coating. In addition, mold, green growth or cracks may appear.

Protect the external walls of the house from different materials from moisture, the appearance of efflorescence and other unpleasant formations - facade waterproofing is used for this. Waterproofing of the façade can be carried out special compounds, and protection can be used slab materials, paints or membranes.

All these procedures can be carried out for a building that has already been built or is just under construction. To protect porous materials, for example, the surface is impregnated by special means, they promote water repellency and contain acrylic, silicon and organic components.

About the benefits of waterproofing external walls

Efflorescence is a white salt coating that appears on the walls of houses. All this happens due to the fact that water, along with salts, moves inside the material. When the weather is sunny, moisture rises and dries, and the salt remains, forming an unsightly white coating.

Hydrophobization is often used for important cultural objects. The material from which the object is constructed may be too “fragile” for other methods of protection.

After the facades are treated with hydrophobic compounds, they will not be exposed to water and moisture, and the facades will become much easier to clean.
Those treated indoors retain heat better, all because impregnation provides improved thermal insulation. Fungus, mold and other “moisture lovers” will not be on a dry wall, and accordingly the wall will remain not only dry, but also intact.

There are many water repellents, but those that contain silicone or silicon are ideal. Using a silicone-based water repellent, your building will continue to “breathe”, because silicone allows air to pass through.

What external wall materials can be protected with chemical compounds?

Hydrophobization of the facade is not suitable for all materials; only materials that absorb moisture are suitable, for example: brick, gas blocks, tiles. The application process itself is simple; it will be enough to apply the waterproofing substance to the surface using a brush or spray. This method is called the “surface hydrophobization method”.

Giving water-repellent properties to building materials during their production is called the method of volumetric hydrophobization. The best results are achieved when these two methods are used.

This provides maximum protection against moisture, dust and efflorescence. The best results are achieved when these two methods are used. This provides maximum protection against moisture, dust and efflorescence.

How to protect the brick facade of a house?

Be sure to clean the surface to be treated from salt and dirt before applying the water repellent. Walls that are saturated with moisture can also be hydrophobic, but to achieve the most better effect work should begin after several days of warm weather. During these days the wall will dry and be ready for processing.

The essence of the work comes down to sealing the pores in the brick itself and its seams. Apply the liquid to the previously cleaned wall surface you want to protect. Due to the fact that the brick itself is a porous material, the solution can penetrate into it quite deeply, up to several centimeters.

A colorless water-repellent film will be created on the surface. If the seams have become very frayed over time, they can be filled with a new solution before applying the water repellent to give a more fresh and aesthetic appearance.

Protection of plaster facades

They are also susceptible to destruction from moisture, and therefore will require waterproofing of a plaster façade on any basis.

Organosilicon additives are used to protect them; they protect against moisture and increase the drying speed. plaster finishing 2 times. The process of their preparation is normal and does not involve any special technological processes.

The solution can be prepared both at the work site and at units specially designed for this, but the solution must be made in a mortar mixer.

Application to the walls takes place in the usual way, using a brush or spray gun. After treatment with hydrophobic liquids, the facade will be protected from moisture and dirt, which can ruin its appearance, especially if the facade is bright in color.

Protecting wood from moisture

Wood is beautiful natural product and building material. But without careful care, it can lose all its properties, constantly leading to costs.

A wooden facade must be treated with water-repellent elements, otherwise it will not last long and will lose its appearance.

Special hydrophobic impregnations have been developed for wood, which penetrate into the deep layers of wood, perfectly protecting it from moisture. In addition, such impregnation does not create a film, which allows the wood to breathe.

Before applying the water-repellent layer, the wood must be prepared, sanded along the grain, and all accumulated dust removed. Wood with defects is subjected to restoration using special putty solutions.

It is advisable to apply the water repellent in dry weather so that there is as little moisture in the wood as possible.

Protection of aerated concrete

Aerated concrete blocks themselves strongly absorb moisture due to their porous, open structure, and therefore over time they fade, oxidize and become excess weight. To protect against all these misfortunes, you will need waterproofing of the facade made of aerated concrete blocks, which consists of several methods.

It’s worth noting right away that slabs made of extruded polystyrene foam, cement and film paints are not suitable for cladding; all these substances do not allow air to pass through and, accordingly, the wall cannot breathe.

Protecting aerated concrete with plaster

Let's start with plaster. For aerated concrete blocks there are special plaster compositions, which can protect cheaply and efficiently. But remember, the thickness of the plaster should be such that it can be vapor permeable.

During its application it is necessary, especially where the tension is increased (windows, corners). Do not plaster in the cold and do not allow the plaster mixture to dry out.

Protecting aerated concrete with siding

Siding for aerated concrete houses provides the best protection from all kinds of weather whims. Lining, ceramic sheets or metal - there is a wide choice, and everyone will find something they like.

Additional a nice bonus It is possible to insulate the house with special insulation materials that can be laid under the facing material.

Painting aerated concrete

Textured mixtures and are the cheapest way to waterproof a façade made of aerated blocks. The main thing is to remove all flaws from the wall, bumps, potholes, etc., which can worsen the appearance and quality of the paint.

The seams between the blocks will have to be sanded. These types of putties are vapor permeable, which allows the building to breathe.

Drainage from the roof

To protect facades from snow and water, drainage systems are used, which are currently on the market big choice. Usage drainage systems– this is also one of the aspects of an integrated approach to waterproofing facades made of various materials.

Installation quality system catchment will increase the lifespan of your roof and facades. Modern gutters are complete works of art, ensuring complete removal of rainwater from roofs of any shape.

They are made from several types of material: steel with zinc coating, copper and gutters based on zinc-titanium alloys. A good wide roof will prevent rainwater from reaching the facade, but will not protect against direct rain.

Snow guards

During the winter season, modern snow retainers will help you retain large amounts of snow.

They not only protect against snow falling on your head, but also prevent it from entering the drainage system, which can lead to its breakdown. Modern market provides several types of the most effective snow retainers: yokes, snow supports, lattice and tubular logs. The choice of snow guard depends on the type of roof you have.

Almost everything in a house needs protection from moisture: the roof, openings, foundations and walls. Any wall - brick or wood - must be reliably protected from liquid. And when dampness appears on the walls, their waterproofing is not always to blame - often a poor-quality foundation can fail at the most inopportune moment. And, as you know, there are capillaries in the walls through which water can rise higher and higher. Moisture can also enter the walls from the roof if the waterproofing is not done properly. How protect walls from moisture?

Waterproofing the wall should start from the bottom. 10-20 cm above the blind area you need to perform horizontal waterproofing. You can immediately worry about vertical waterproofing. To do this, you can drill several holes in the wall at a slight angle and pour insoluble silicon elements into them. Now the capillaries in the wall will be filled with a solution through which soil moisture simply cannot penetrate. The part of the walls that is in direct contact with the roof must be reliably protected from atmospheric moisture. In addition, it is important to take care of the outer part of the wall. But first things first.

Creating a hydrophobization effect

From the very beginning, you need to create a boundary for moisture to enter through the outer part of the wall. By hydrophobizing walls, it is possible to prevent their wetting. When applied, water will not penetrate inside, but will simply roll onto the blind area, from where it will then be diverted away from the building. When deeply treated with the substance, the materials will receive protection from moisture for the entire period of their operation. Before applying a water repellent to the surface, it must first be cleaned.

Another way protecting walls from moisture– use of plaster waterproofing. It is applied to the wall with a spatula, after which the surface can be finished with any material. Even ordinary cement, applied in a millimeter layer, can be used for these purposes. But when prolonged exposure water makes the cement wet. But if you add to it liquid glass or ceresite, then the water protection will become more effective.

Polymer mixtures – effective remedy in the fight against moisture

If you use it completely ready-made mixtures, which include fillers, binders, mineral and polymer additives, then you can provide high-quality protection of walls from moisture. It is known that these substances have minimal interaction with liquid. After their application, the walls can be covered with porous plaster or facade paint.

Another remedy for protecting walls from moisture- These are moisture-removing plaster mixtures. They not only protect walls from moisture, they are even able to draw water out of them and evaporate it. Penetrating waterproofing has also been developed. A wall that is protected in this way is not afraid of even direct contact with liquid. After all, this type of protection reliably fills cracks, voids, pores and capillaries, so that there is simply no room left for water.

Other ways to protect walls from moisture

Another type of waterproofing is a mixture of quartz sand, Portland cement and chemical elements, which will simply seal the pores of the walls. Before applying the coating, the surface should be thoroughly cleaned of dust and oil stains. The brickwork should be embroidered half a centimeter deep. Now it should be sealed contained in cement mortar waterproofing mixture. This is very reliable protection– water is more likely to enter the house through a window than through the walls.

As you can see, people have achieved some success in protecting walls from moisture. However effective methods they are very expensive, but they do not provide affordable comprehensive protection. An ordinary dry mixture is often used as a coating waterproofing material. It is created on the basis of special polymers and cement. With its help, you can obtain an effective frost-resistant and elastic coating that has waterproof properties and good adhesion. To create such protection, you first need to clean the wall from dust and erosion using a wire brush. In cases where the partition is damp, it should be covered with quick-drying cement. Each component of paint or plaster must be mixed. Try not to prepare a large amount of the mixture, because you may not use it right away, and then it will become unusable.

Without wasting time, you need to apply several layers of the substance to the wall. If it is a moisture-repellent paint, then the strokes of each subsequent layer should be applied perpendicular to the previous one. You should work in a respiratory mask. Although protecting walls from moisture requires financial and time costs, with its help you can reliably protect your home from sad consequences. It is known that in damp walls Mold and fungi develop, which often harm our health. Therefore, if you are concerned about the well-being of yourself and your family, then take the time to worry about high-quality protection of your walls from moisture.

Protecting a brick wall is an important step, since the material absorbs moisture from the soil. As it rises, it can reach the upper floors of the building, destroying the masonry. As a result, the rooms will become damp and mold and mildew will begin to spread.

High-quality waterproofing protects brickwork from moisture and dampness.

Protection of brick walls must first be carried out from the outside, this is the first stage of work. If this is not done, the device internal waterproofing may enhance Negative consequences. Creating protection inside the rooms will lead to even greater saturation of the walls with moisture. The dampness on the upper floors will become stronger.

Your job is to protect brick wall, base or foundation from dampness. First, make high-quality waterproofing on the outside. It is very good if this stage of work is carried out at the stage of construction of the building.

Options for protecting basement masonry

When building houses they are used the following types protection:

coating:
pasting;
clay castle;
the use of plaster with special modifiers included in it;
screen

Clay castle is a method that is based on constructing a ditch around the foundation. Liquid clay is used to strengthen the walls and bottom. Then the ditch is filled with gravel, and a blind area is built on top. Screen waterproofing involves working with bentonite mats; they are laid overlapping.

These 2 types of waterproofing are good to use to protect the brickwork of the basement, but work must be carried out during the construction of the building. The clay castle and the laying of screens cannot be considered the only possible options. Plaster mixtures and the hydrophobic modifiers introduced into them make it possible to reliably protect the masonry from groundwater.

Coating waterproofing involves the use of mastics made on the basis of bitumen. The addition of synthetic resins or other fillers increases the protective functions. Before treating a brick wall with mastic, thoroughly clean the surface.

The lining is very effective; it is based on the use of fiberglass materials. It's simple and cheap way protection of the foundation and basement masonry from groundwater.

Protection of masonry walls

Seams of brickwork located above ground floor, are also vulnerable to moisture. Ceramic stone Today it is used most often; due to excess moisture, it begins to deteriorate.

Brick is a porous material, and masonry seams can be called a weak point. When moisture rises along the walls, the following troubles are possible:

the appearance of whitish salt formations;
In winter, moisture freezes to form ice;
destruction of masonry;
heat leaves the building.

Treatment brick surface is done in stages.

A special impregnation is best suited to protect bricks from moisture.

After processing it will be completely protected. In addition, brick walls will become very beautiful, and the durability of the structure will significantly increase. The product creates a water-repellent layer and excellent vapor barrier. This is achieved due to the penetration of impregnation into the brick by 1 cm. As a result, the stone wall is not afraid of rain, snow and melt water will also not have any harmful effects.

Impregnations are available for sale in specialized stores. It is worth mentioning the following products, which differ from each other in composition:

Water-repellent impregnation for bricks. It is most in demand because the product has excellent protective characteristics.
Silicone impregnation. Remedy for water based, it consists of 2 components.
Impregnation varnish. By applying it to the walls, you will get a surface with a slight gloss.
Silicone acrylic impregnation.

Impregnation for bricks has a water-repellent effect. On the surface of the brickwork, the products form a very thin hydrophobic film, which reliably seals the pores of the brick, preventing moisture from penetrating inside. The destruction of the brick stops.

Before starting work, you need to identify sources of moisture penetration. To do this, examine the seams. If they are not destroyed, then simply apply impregnation to the walls. If there is visible damage to the seams, first carry out restoration work, and only then cover the walls with a protective agent.

Inspect stone walls once a year. Remove dirt with water or a special paste. No less effective mechanical cleaning. To remove traces of salt on the walls, use special solutions. Be sure to treat mold and mildew with antiseptics.

It is best to apply the product to dry and clean brick walls. Wait for dry weather and then get to work. If the mortar in the masonry joints crumbles, remove it. Replace crumbling parts of the masonry, lay new brick. Apply impregnation to the masonry and let dry. This is the preliminary stage of work. Then seal all seams.

If you want to get a good result, then make sure that at least a day passes between the preliminary impregnation of the masonry and the finishing part of the work. Then seal the seams by applying cement-sand composition layer 2 mm. Using a sponge diagonally, rub in the solution. Remove excess and wait until the solution has completely set. To remove residue, rinse the wall thoroughly cold water. Cover the seams from sunlight. Wait 3 days and then apply finishing impregnation. This is an excellent hydrophobic coating for sand-lime bricks.

If there is no need to repair the seams, apply protective impregnation in 2 layers. There should be a little time between coats 1 and 2, but waiting 15 minutes is enough. There should be a visible shine on the wall; such a coating will last at least 10 years. Now you know everything about how to protect walls.

Conclusion

Protection of brickwork consists of 2 stages. First, waterproof the foundation, and then move on to protecting the walls of the building from precipitation. Use special impregnations.

The products form a thin hydrophobic layer on the surface of brick walls, which prevents moisture from penetrating into the masonry.
