What is A French Drain
A French drainage system is a trench covered with gravel or rock that redirects surface and/or groundwater away from an area. A French drain has a perforated hollow pipe along the bottom to capture water that seeps down through the upper gravel or rock. French drains are common drainage systems, primarily used to prevent groundwater from migrating under the foundation. Groundwater under a foundation can cause movement beyond seasonal norms. French drains are also used behind retaining walls to relieve hydrostatic pressure.
