French drain and foundation

If you have water infiltration problems in your home or if you have noticed cracks at the base of your foundation, then you are probably having problems with your drainage solution. Fortunately, Pavé IHM is here to explain how to solve the problem and help you determine signs of aging of your French drain.

What is a french drain?

In a few words, French drain is a drainage pipe that is installed along the foundation area.

Its function: to drain the excess water that accumulates at the base of the building in order to avoid any water infiltration inside it. With French drain, you avoid many problems caused by water infiltration, such as mold and the proliferation of bacteria that can crack your foundation and cause very costly damage to be repaired.

The French drain is perforated to allow water to enter and drain away. The pipe is often wrapped with a geotextile filter (flexible polyethylene, standard flexible polyethylene, pcv/bnq) in order to limit the accumulation of sediments that can reduce its performance.

Have a french drain installed by specialists

It is essential to call upon specialists, such as those working for Pavé IHM, to install your French drain, because, in addition to the standards to be respected, it is absolutely necessary to check the presence of electrical wires, gas or any other connection or pipe before starting work. This is a delicate practice.

Only then can we go through the excavation stage, i.e. dig around the house, all the way to the foundation base in order to position the filter that will protect the foundations.

The French drain is then installed around the perimeter of the house, while ensuring that it is sloped to promote water drainage. Finally, the drain is covered with clean stone and then covered with a geotextile membrane to prevent small residues from blocking its operation.
