Aquadrain G20 is a two part prefabricated drainage composite consists of a high strength HDPE geonet core with a nonwoven polypropylene filter fabric bonded to both sides. It is designed for horizontal and vertical applications requiring very high compressive strength with low to moderate flow properties. The fabric is bonded to the core to minimize fabric intrusion into the core resulting from backfill pressure. The HDPE geonet core provides high compressive strength and a moderate water flow. The non-woven fabric allows water, or other liquids to pass into the drainage core while restricting the movement of soil particles.
