Foundation drainage system - French drain & drainage mat

Foundation drainage system - French drain & drainage mat: This line item refers to the installation of a foundation drainage system that includes both a French drain and a drainage mat. A French drain is a trench filled with gravel or rock containing a perforated pipe that redirects surface water and groundwater away from the foundation. The drainage mat is a sheet of material placed against the foundation wall to provide a drainage space, allowing water to flow freely into the French drain. This combined system helps prevent water accumulation around the foundation, reducing the risk of water damage and maintaining the structural integrity of the building.
