PowerDrain 6000 geocomposite consists of a dimpled High Density Polyethylene (HDPE) core and a fully bonded polypropylene filter geotextile. The dimpled HDPE core acts as a drainage plane that allows moisture from the soil to flow to the drain-age rock below. The attached non-woven filter geotextile allows water to freely pass through it, while protecting against soil and other sediments entering and potentially clogging the drainage plane. When properly installed, PowerDrain 6000 creates a 10mm gap which relieves the hydrostatic pressure that would otherwise be acting on the foundation wall.
