Prefabricated Geocomposite Sheet Drains

American Wick Drain Prefabricated Geocomposite Sheet Drains

American Wick Drain Prefabricated Geocomposite Sheet Drains have a flat back which is pressed against an underground structure, such as a basement wall or subsurface footing. The pressure of backfilled soils holds the sheet drain in place. A filtration geotextile covers the drainage core. The geotextile allows unrestricted flow of moisture into the core while it restricts the passing of soil particles, which could contaminate and clog the core. Since most of the soil-exposed surface of a subsurface structure is covered with the geocomposite sheet drain, hydrostatic pressure is virtually eliminated. At less than 5oz/sf, geocomposite sheet drains are very lightweight, easy to handle and easy to install. They require no special equipment or skilled labor.
