A gravel-filled trench with a perforated pipe that collects and redirects underground or surface water away from a building.
A trench filled with gravel or rock containing a perforated pipe that redirects surface water and groundwater away from areas where it would cause problems. French drains are used for foundation drainage, landscape drainage, and surface water management. The perforated pipe collects water through small holes, and the gravel provides a path for water to flow into the pipe.
A French drain was installed along the uphill foundation wall to intercept groundwater before it could cause hydrostatic pressure.
