Drainage of the foundation of the building

Drainage of the foundation of the building

When the foundation is placed, its drainage is necessarily provided, regardless of what foundation. Drainage must be used due to soil and its water permeability. Increase in groundwater leads to dampness in the basement of the house. The foundation can be deformed that the soil that was nourished by moisture is swelling. The drainage of the foundation is designed to normalize the level of groundwater. This foundation can be performed according to different methods of open and closed.

Draining without pipes is called open, and if pipes are used in the drainage system, drainage is called closed. To protect the underground part of the structure from groundwater, sometimes drainage is used around the foundation. In this case, the system is installed along the contour of the building, where the system of the system must have a slope for water stack in a water intake or well. Trenches are filled with gravel, and in order not to be washed out small particles of the soil, waterproofing materials are used. Ring drainage excludes the likelihood of flooding of the basement. Drainage in the form of an unmarked circuit is used if the flow of groundwater is on one side. To perform a drainage foundation, it is necessary to make the necessary calculations and the project. Non -compliance with calculations and project can lead to unnecessary consequences, for example, the stability of the building is reduced.
