Construction of houses adjoining drainage. Types, kinds, the need for resettlement.

Why do we need a drainage system?

Drainage plan is necessary even during the foundation of the house favorites. If you do not, then ground water can destroy the foundation and the house in general. Particularly relevant drainage in clay and loamy soils. Drainage is required in areas where they often fall precipitation (Moscow, St. Petersburg), if laid on a plot paths of concrete that covers the natural water drain, if there is a risk of flooding the basement premises.

Apparatus drainage system

The drainage system consists of the following elements:

— drains (Drainage pipe) made of polymers. They filtered water from the sand. The ability to install corrugated pipe with filters.
— wells - placed at the points of bending Drenov. They are needed for maintenance Drenov. There are 2 types of wells: the collector (designed to collect water) and inspection (required for system maintenance).
— pumps - set for evacuation in case of impossibility to output water in a natural way.

types of drainage

Depending on the features of the site and drainage objectives possible to install several types of drainage system:

— surface drainage - a simple type that can be called a storm sewer. It mounted after all the construction work at the site completed. Such a system can only take surface water, which appeared as a result of rainfall or snowmelt.
— Linear drainage. It is placed on the perimeter of the frame house in a small shallow trenches. Linear drainage is also one of the types of drainage, it is necessary in cases where there are no designated areas to drain the water.
— point drainage mounted under the base at those points where the water accumulates (e.g., under the drain). The system consists of pits, filled with concrete pad at least 10 cm, and pipes that connect these pits and expel water from the house.

— subsurface drainage It is a system closing.
— The deep drainage install in places high location of groundwater.

types of drainage

In the method and arrangement of structure are several types of drainage:

— ring drainage arranged around the carcass home, if there is no basement or ground floor. It should be located at least 5 meters from the building. Perhaps the combination of the ring to the storm sewer drain. This drainage is a closed system of tubes disposed in the corners of manhole.
— The reservoir drainage located under the base frame house, it is intended to collect ground water and capillary moisture. Such a system should be installed in clay soils.
— Perimeter drainage It protects the ground floor or basement moisture. He mounted after the completion of all construction works. His suit around the building, and then combined with other kind of drainage of open or closed type.
