A solid stone or brick house is defenseless before the constant effect of precipitation, moisture is destructive for all buildings without exception. The reason lies in the fact that in the warm season, water fills the micro -general in the foundation, gradually layers of bricks lying on the foundation are impregnated with moisture. In the cold season, water at minus temperatures freezes. Since freezing water increases in volume, the formed ice in the microcracks of the walls and foundation swells and begins to destroy the building material.
