Prefabricated Drainage Composite

US SWD-6 is a modular composite drainage and collection system consisting of a 3-dimensional, high flow drainage core which is wrapped with a nonwoven filter fabric. It is designed to replace conventional sand or gravel covered pipe drain around building foundations and retaining walls.

Soil particles are held back by the filter fabric allowing water to pass through the drain core for easy removal by sump or by running to daylight. A full array of fittings are available.
