French drains are used to prevent water from penetrating or damaging building foundations and other structures.

A french drain is a trench filled with gravel or rock or containing a perforated pipe that redirects surface water and groundwater away from an area. A French drain can have perforated hollow pipes along the bottom to quickly vent water that seeps down through the upper gravel or rock.A French drain goes by a number of names:
