This drainage composite consists of a post-industrial recycled polypropylene drainage core of fused, entangled filaments and a geocomposite fabric bonded to one side. The entangled filaments are molded into a square waffle pattern that maintains the flexible design of other Enkadrain products. This product, because it has 40% postindustrial recycled content, can help contribute up to 2 LEED points when used in conjunction with other recycled content products. Enkadrain 3611R can contribute towards additional LEED points when used with a green roof by reducing storm-water runoff, heat islands and energy consumption.
