TenCate Polyfelt® Megadrain drainage composites are monofilament geomats from polypropylene, with a filter nonwoven (TenCate Polyfelt® TS) on one or on both sides. The extremely high voids content of TenCate Polyfelt® Megadrain ensures a high water-flow capacity, especially at low overburden pressures.
