French Drain Installation
A French drain, also known as a weeping tile, is trench that is filled with rock and perforated PVC pipe. The purpose of the French drain is to redirect surface and ground water away from an area (in most cases a home or buildings foundation). French drains can either be installed around the exterior foundation walls or can be installed inside the crawlspace around the foundation. Interior French drains must be installed in conjunction with a sump pump.
