Drainage Mat made of impermeable High Flow Dimpled Polypropylene

Drainage Mat Enkadrain 3611R

Enkadrain 3611R is one of a new generation of environmentally conscious Enkadrain products.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 exceeds 40% post-industrial 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 stormwater runoff, heat islands and energy consumption.
