A French drain works with gravity. Water follows the ebb and flow of the earth's guiding principle, and thus, the drain carries water downstream. This sloped trench provides a method to help homeowners avoid damp patches on their lawn or property by regulating drainage, and keeping things dry in places where it's necessary.

Needless to say, the long-term durability of a house depends heavily on the lack of seepage, above all in the foundation. Excessive humidity can have devastating and damaging long-term effects, both on your home and your health. Moreover, mould and bacteria growth can end up being very costly.

The French drain plays a highly important role in preserving your home's integrity, as water accumulating near the foundations can seriously damage a home and lead to expensive renovations.
