The French drains consist of a small filling trench that helps keep water away from the building’s wall surface.

Many people use them on sidewalks or in gardens when they know that the land is prone to flooding.

Sometimes surface water does not drain properly due to soil and many other factors.

Water flows through a gravel channel and then flows into a pipe at the bottom of the drain. Water flows through the pipe and then safely flows out of the house.
