Works on waterproofing walls and floor

In some houses you can see an unpleasant odormold and damp. This is especially true for the basement and first floors of private houses. This occurs in places where the waterproofing of the building has been disturbed. Any construction at the stage of erection requires protection from the negative impact of moisture, this applies not only to the walls, but also to the floor. If such works were not performed in time, then the problem can be rectified at the stage of building operation.

Sources of moisture can be precipitation,ground water and air humidity. It is important to waterproof the walls of the cellars with masonry, the first floors, as well as the rooms, whose walls are in contact with the concrete foundation. In this case, the material is easily saturated with moisture, as well as those places where it is theoretically possible to flood, here you can include bathrooms, kitchens, bathrooms and swimming pools.

Oble waterproofing of walls

Work on waterproofing canto be carried out with the help of penetrating and lubricating waterproofing. The last version in the base contains synthetic resins, polymers, cement mastics and cement mixtures with different fillers. For monolithic walls, a cement-and-sand screed must be made to level the wall to save materials.

Work on waterproofing involves a primerSurface to increase adhesion with the following layers. At this point, the substrate should be left until it dries. Further, a coating of waterproofing is applied. The last step is the installation of a drainage system, these can be spike-like membranes. If the wall consists of reinforced concrete prefabricated structures, then it is not necessary to align it. Further work technology looks the same.

Penetrating waterproofing of walls

Penetrating waterproofing is a mixture thatfill the pores of concrete, but leave him the ability to breathe. This method is used only for reinforced concrete and monolithic structures. Leveling the surface is not necessary, and proper preparation involves removing the screed and cleaning the base with iron fleecy brushes. To do this, you can use sandblasting plants, with which dust and dirt are removed from the walls.

The substrate must be treated with antifungalmeans or impregnate with water by spraying. At the next stage, a waterproofing mortar is applied, which protects against moisture and increases the frost resistance of concrete. Especially carefully it is necessary to process potholes, cracks and places of abutment of walls. Use for such work can be Penetron. The places of junctions, joints and seams are treated with the appropriate materials of the Penecret type. Surfaces are left for three days, during which time they must be moistened.

Floor waterproofing

Work on waterproofing in the house should becarried out also in the field of sex. First the base is leveled. Then you can start applying liquid waterproofing. Usually, a brush is used for this. As a composition, the usual bitumen is used, which is heated before use. The next step is to lay the film materials in two layers. It is important to ensure the overlap of the canvas, which is 20 cm.

On the surface of the walls, the film must go 30see Rolls of pasting waterproofing should be rolled up along the premises. The material should go to the walls. It is glued to the surface of the floor, and after the completion of the work, the excess material should be cut off. Such work on the waterproofing of the floor is carried out before pouring the screed.

External waterproofing of walls

At the first stage of waterproofing of external wallsIt is necessary to reduce the level of groundwater using the method of drainage. After that, you can start preparing the walls. They are cleaned of dirt and closed cavities. Traces of rust and oil stains should be removed. The wall is left until it dries out before applying the primer. Drying should be done in a natural way.

Then you can start applying plasterwaterproofing. To begin with, the notch is grounded. To do this, use a hammer and chisel. Before applying bitumen formulations, a primer should be applied, which is prepared from gasoline and bitumen. The application of a primer is usually carried out with a brush or spray gun.

Often used todaywaterproofing for outdoor works. It is made of synthetic resins. Suitable for these jobs are cement-polymer mastics and bitumen-based polymers. The walls are leveled with a cement-sand screed, and then the surface is treated with a primer. In the role of coating material, the following compositions are often used:

• "Trimsmes".
• "Cemisol 2EN".
• "Isotope is a DK".
• "Ascovil".

Waterproofing for foundation

Work on waterproofing the foundation can beare realized with the help of "Hydroisol". It is on sale in a liquid version, which has the appearance of bituminous mastic. Among the ingredients are polymeric fillers and bitumen, which are able to protect from moisture any surfaces.

Application should be carried out with a spatula oncleaned surface. The material is leveled and left until the point of hardening. There are solvents in it, which gradually evaporate, this gives the mastic strength. "Gidroizol" is offered on sale in several varieties, which can serve without censure up to 30 years. Such a waterproofing for outdoor works on concrete is perfect. It fills the pores, so before carrying out the manipulations it is necessary to clean the surface to open the ways for the penetration of the material.

Works on oilproofing the foundation waterproofing

To begin with, the foundation surface is cleaned ofpollution. It is important at this stage to eliminate sharp edges, then the obtained places are sealed with a solution of cement and sand. The foundation is covered with a primer and left until it dries. Then you can prepare the mastic. If it is a two-component composition, it is mixed.

The prepared solution is applied with a roller orBrush in several layers. However, before proceeding with the application of the next layer, it is necessary to allow the previous one to dry. Such work on waterproofing at the final stage provides for filling the foundation with construction sand or soft soil.

Conclusion

For waterproofing works inthe area of ​​the floor and walls can use different materials. Among them, it is necessary to distinguish pasting, coloring, coating and plastering mixtures. Compositions can be injectable, sprayed and penetrating. Works on waterproofing are carried out using different technologies. In the case of paint materials, they are applied with a thin film, which consists of mastic, paint, varnish or bitumen.
