J-Drain 302 is a Heavy-duty, high-density, polyethylene geonet drainage core that allows filtered water to pass through both sides. Applications consist of retaining walls, plaza decks, planters, green roofs, under slabs, and bridge abutments. This drainage system is designed to be crush proof, which allows it to place in areas with high load requirements and high vehicle traffic. J-Drain 302 also has filter fabric on both sides of the geonet, providing drainage and filtration from both sides. This facet of the product allows for both soil retention and for maintaining water cleanliness throughout the drainage system.
