Waterproofing the facade of the house

During the operation of any structure, the waterproofing of its external walls is considered one of the most important points. This need is caused by the periodic impact of precipitation on them, which contributes to the gradual destruction of the construction of external walls. In practice, moisture through microcracks can penetrate a brick or concrete. At low temperatures, it turns into ice, destroying the structure of any building material. Therefore, we need waterproofing of the facade of the house, preventing a number of undesirable phenomena.

Among them may appear on the surface of the facade efflorescence in the form of a white salt deposit. This phenomenon greatly spoils the appearance of any building. Moreover, the moisture that has penetrated to the reinforcing frame of the reinforced concrete wall, causes corrosion of metal elements. In turn, this leads to a loss of strength of the supporting structures of such a structure and cracking the surface of the external walls.

Features of waterproofing

The general concept of waterproofing implies a set of special measures aimed at the effective protection of facades of structures from the destructive processes that are caused by the ingress of moisture on them. Today, it is the most economical way to protect cellular concrete surfaces, ceramic and silicate brick walls from the damaging effects of moisture. It can penetrate the porous structure of the material, filling in multiple voids.

At sub-zero temperatures, the water freezes in the pores of the materials, and begins to expand. This causes microscopic destruction of the structure of the finishing materials of the facade of the building. When water is thawed, salts that are inside the walls begin to go out with the liquid, forming unwanted white spots. Such formations clearly spoil the presentable appearance of any facade. Moreover, undesirable delamination and destruction of individual facade fragments may appear on the outside of the walls.

Materials

Today, various materials are used for waterproofing facades, which can differ in their properties and the method of application to the surface. They are divided into several groups. Namely:

• penetrating mixtures;
• rolled waterproofing materials;
• insulating mastics;
• expanding cement based mixtures.

Penetrating compounds capable of filling the pores of structural building materials. They are liquid glass, quartz sand with chemical additives, as well as some types of mixtures based on mastic. The main area of ​​their use is vertical wall waterproofing.

Rolled waterproofing is available in the form of roofing felt, its modern analogues based on rubber, as well as waterproofing membranes. One of the main advantages of such materials is the convenience of applying them to the surface of the basement or foundation walls. In addition, such insulators have durability and contribute to the preservation of the heat of the building, since they have a certain thickness of the layer that does not transmit heat well.

Wall waterproofing works

The complex of works aimed at ensuring the waterproofing of the facade can be done by hand, following all the technological conditions and building rules. At the same time, one should not forget about personal protective equipment. Protection of exterior walls from moisture should be ensured at the final stage of facade finishing. The insulation layer should be applied on top of a lining such as brick, stone, plaster and other materials. As a working tool, special rollers and wide brushes are usually used.

Waterproofing exterior walls involves applying a protective layer on the basement of the building, as well as on its walls. Since the basement of any structure is in close proximity to the ground surface, it is better to use bitumen mastic and roofing material to isolate it. These materials can provide the most effective protection to the foundation of a building against moisture. Mastic should be applied to a dry surface using a wide brush. Roofing material should be glued with vertical stripes. Thoroughly smearing the edges and joints with a bitumen mortar.

Waterproofing of the walls of the facade must be performed using special penetrating compounds, which today are offered in a wide choice. In the work you need to use special rollers and brushes. Do not leave the raw fragments of surfaces, promazyvaya each section of the outer part of the facade of the building. The waterproofing compound must be applied in smooth, short strokes, processing all the protrusions and the inner corners of the outer walls. Important: it is necessary to clearly follow the instructions attached to the material in order to ensure reliable coverage and to protect the walls from moisture penetration.
