The drainage system is a complex engineering structure. It consists of pipes and drainage wells, and is installed in the entire area where the construction is planned. The main function of the drainage system is to protect the site from moisture. You can order signs inexpensively according to the above link.
The main element of the drainage system is the pipes indicated in this case by drains. At the moment, they are produced from modern materials, including a composite and polymers, which are distinguished by special filtering functions. They pass only water, blocking the entry of land or other solid materials into the drainage system. This type of pipe give the system a greater degree of reliability and efficiency. Meanwhile, plastic pipes are often used often. In the course of production, a special geotextile shell is applied to them, which also has the properties of filtering.
The drainage system also has pumps installed in the wells. The pipes themselves must be laid with a slope towards drainage wells. In this case, the water accumulated on the site is collected in only one specific place. But the distance between the pipes is determined by the water resistance of the soil, as well as the purity of precipitation.
