A French drain or weeping tile (also blind drain, rubble drain, rock drain, drain tile, perimeter drain, land drain or French ditch) is a trench covered with gravel or rock or containing a perforated pipe that redirects surface and groundwater away from an area. A French drain can have perforated hollow pipes along the bottom (see images) to quickly vent water that seeps down through the upper gravel or rock. French drains are common drainage systems, primarily used to prevent ground and surface water from penetrating or damaging building foundations. Alternatively, the French drain technique may be used to distribute water, such as a septic drain field at the outlet of a typical septic tank sewage treatment system. French drains are also used behind retaining walls to relieve ground water pressure.
