TeraPROOF^™ 10-11 Drainage Mat is a high-performance, two-layer drainage composite designed for below-grade system applications. It features a dimpled drainage core made of impact- and tear-resistant co-polymer polypropylene, bonded to a high-strength, needle-punched polypropylene geotextile—allowing water to pass freely while blocking soil particles to prevent clogging. The product ensures a continuous water drainage plane and relieves hydrostatic pressure. Suitable applications include underground walls, pile and lagging walls, retaining walls, bridge abutments, and hydrostatic pressure relief layers. Available in 4 ft. and 6 ft. wide rolls that are 50 ft. long.
