It is known that any construction process begins with the construction of the foundation. It is also known that any foundation must have drainage. This need is due to the properties of the soil. To be more precise, its weak water permeability.
Very often, especially in spring, when the groundwater level rises significantly indoors, the humidity level rises, which can only be controlled through a drainage system.
There are different types of drainage. For example, if pipes are used in this case, then such a system will be called closed. In this case, special drainage polypropylene pipes are used. If the system was installed without the use of pipes, then in this case it will be an open system.
One of the most common drainage systems is ring drainage. Its peculiarity is that the entire system is mounted around the perimeter of the foundation. In this case, there must be a slope. This is necessary in order for water to enter the well or water intake.
Before proceeding with the installation of the drainage system, it is necessary to prepare a trench. In this case, a crushed stone pillow is made. In addition, it is very important to prevent washing out of small soil particles. For this purpose, waterproofing materials are used. Thanks to the annular drainage, it is possible to exclude the possibility of flooding the basement floors with groundwater.
Sometimes, if the flooding of the building occurs only on one side, then it will be enough to use an open drainage system.
It is also worth noting that before proceeding with the installation of the drainage system, regardless of its type, it is necessary to carry out the necessary calculations. The result of the calculations will be the drafting. Drawing up a project is a mandatory step that allows you to avoid unforeseen situations that arise during the operation of the building.
In the case of mounting a drainage system in an already finished building, some nuances should be taken into account. Under no circumstances should the foundation be undermined. The thing is that there is a risk of subsidence of the whole structure or part of it. To avoid this kind of problem, a drainage trench should be dug at some distance from the foundation. In addition, the trench should be dug slightly lower than the level of the foundation slabs. It should be noted that in such a situation only an annular drainage is mounted.
Only through competent planning of the drainage system, as well as with the high-quality implementation of this project, it is possible to achieve the desired result.
