As a result of climate change or increased precipitation, hydrogeological conditions in a given area may change. Therefore, the fact that we are not currently affected by the drainage problem does not mean that we will not be affected in the future. Magnaplast drainage pipes are a comprehensive answer to all the issues related to the excess water in the soil. The full range of products, including the pipe system and drainage fittings, as well as inspection chambers necessary for the assembly process, is confirmed by material durability tests and a guarantee for the entire installation at a single manufacturer.
Drainage is needed wherever:
- There is a high level of groundwater,
- Groundwater appears during excavations for foundations,
- There is a heterogeneous soil around the building, e.g. impermeable layers (clay, silt), which, due to the lack of outflow of groundwater, will cause the walls to get damp.
If drainage was to be provided during the construction work, it is laid next to the foundation walls. If, on the other hand, it is installed next to an existing building, it is necessary to keep a distance of 2-3 m from the walls.
It is very important to drain the house when the house is located on a slope or near it. The water that flows down the slope stops along the foundations. This causes the soil to soften, which in turn can cause the walls of the building to collapse. In this case, drainage is necessary regardless of the type of subsoil, but it is carried out on the elevated side.
Performing a perimeter drain around the foundations serves to collect excess rainwater flowing deep into the ground and lower the level of groundwater around the buildings. In each corner of the building, inspection chambers should be placed; they will be used to flush the pipes and thus remove sediments. More on the inspection chambers: LINK.
