Enkadrain 3611 Polypropylene Drainage Mat Composite

The Drainage composite with post-industrial recycled Polypropylene!

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 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. EnkaEngineered is a commitment to sustainability!

Bury It * Bend It * Shape It * Soak it * Drive over it * Stomp on It * Cut it * Go Green with it * Admire it!

Roof Gradient

Problems

Solutions

Low

1-5° (2-9% )

· Sufficient fall to drain

· Few ponded area may exist

· No major drainage concerns

· Use regular profile Enkadrains (0.4”) to effectively convey runoff to roof drains

· Use EnkaDrain&Retain for green roof designs requiring high water storage capacity
