Drainage Mat mat of impermeable High Flow Dimpled Polypropylene

Enkadrain 3611R

Enkadrain 3611R is a drainage composite mat used in foundation walls, retaining walls, beneath slabs, plaza decks, and green roofs. It 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 storm water runoff, heat islands and energy consumption.

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
