The drainage of the foundation
The drainage of the foundation is an engineering structure that provides buildings with a high degree of protection against the effects of excess moisture. To reduce possible damage from an excessive moist environment, a properly designed and well -assembled drainage system of the foundation is necessary. It helps to prevent the appearance of any, even the most insignificant moldy formations. In addition to minimizing plots with mold, this system will help in solving problems with the emergence of icing both inside the building and outside, as well as with the problems of flooding of basements and the floor of the first floor of the houses. Therefore, the essence of the drainage is to protect the foundation from the negative impact of water with the extension of its operation and drainage of the foundation using the underground system of perforated pipes, thanks to which rain and melt water that seeps from the surface of the soil occurs from the soil around the soil. When laying the foundation of houses, a violation of the hydrological regime of the surroundings occurs, the foundation turns into a kind of dam that prevents the established movement of moisture. Through this, groundwater levels may increase, lowering the stability of the soil and leading to its subsidence with an increase in the strength of frosty heaving. The drainage system well installed inside the foundation helps to avoid this. When installing the pipe drainage system, it should be laid into material that passes moisture well, for example, crushed stone, sand-gravel mixture and sand. To facilitate installation work, it is possible to place in the same trench of the storm sewers and drainage systems, while their upper edge should always be located slightly below the foundation sole.
