We speak of drainage when it is a question of a network used to collect and evacuate water from the ground. The device serves as a protection against the arrival of water for the buried parts of the buildings. On slightly sloping ground, drainage is not very useful downstream. For flat land, on the other hand, it is essential that the drainage surrounds the house.
What do you need for a drainage system?
There can be no drainage without resorting to drains. The latter are available in several versions, but the most used are under-base drains, agricultural drains, and slope stabilization drains. However, it is worth mentioning that agricultural drains are not at all suitable for dedicated sanitation use. Indeed, this type of accessory projects the water on the facade of the house instead of collecting it.
To properly perform their function, the pipes in question must be sufficiently robust and resistant to shocks. The choice can thus be made between perforated PVC pipes, porous concrete pipes, and terracotta pipes.
What are the points to consider before resorting to drainage?
It is important to specify that drainage is not necessarily suitable for all situations. The following three points must first be observed before starting the work:
- Evacuation: does the state of the ground allow drainage water to be properly evacuated?
- The water table: is it necessary to use casing? What other solution can be adopted following the studies previously carried out by the experts?
- The state of the terrain: are we dealing with homogeneous or heterogeneous terrain? Does the adoption of drainage risk feeding the permeable veins and therefore ruining the entire construction?
It is also necessary to make sure that a device for evacuating the collected water remains permanently available before learning about Home drainage.
What are the dimensions of the components of the drainage network?
Depending on the quantity of water to be evacuated , the diameter of the pipe may vary for each installation. As for the minimum diameter of the inside of the drain, this must not be less than 100 mm. A slope between 3 and 10 mm is on the other hand obligatory for the pipe, and this, for a length of 1 m.
The permeability of the land, its relief, as well as its total surface, can have an influence on the overall design of the drainage. These measures may therefore be subject to slight modifications.
Can you do the drainage of your house yourself?
Given the objects to be handled, all the criteria to be met, and the scope of the work, carrying out the drainage of your home yourself can be a complex task. In order to limit the damage and thus avoid inconvenience of any kind, it is always more reasonable to call on a NRC Gravco to take care of it. We can put you in touch with specialists in this field in case you need them.
