Enkadrain W 3601-Composite Drainage Mat for Very Steep Sloped Roof

Enkadrain W 3601 is a proven thin drainage composite which is part of the Enkadrain family of environmentally conscious products. Enkadrain W 3601 A postindustrial recycled white polypropylene drainage core and a very strong but lightweight white Colback filter fabric thermally bonded to one side. Made in the USA. Trusted for over 30 years.

UV degradation for up to 30 days
Even drainage
Light weight
The 40% post-industrial recycled content, can help contribute up to 2 LEED points when used in conjunction with other recycled content products.
Enkadrain W 3601 can contribute towards additional LEED points when used with a green roof by reducing storm water runoff, heat islands and energy consumption.
Made to reflect heat to prevent insulation board warping and membrane softening during construction.
Provides flow in all directions
Conforms to irregular surfaces and corners
Thin drain profile = exceptional performance and minimizes weight

Recommended Applications

 Split slab construction  Plaza decks  Under pavers  Green roofs  Foundation walls

Features and Benefits

Excellent durability
White is Cool! Reflects heat to prevent insulation board warping & membrane softening during construction
Continuous flow in all directions, even under high loads
Protects waterproofing during construction  Conforms to irregular surfaces and corners
Long rolls reduce installation costs by reducing butt seams and eliminating interlocking
Recycled content polymer contributes towards LEED points
3” fabric overlap flap

POLYPROPYLENE POLYMER PROPERTIES

Polypropylene has excellent resistance to organic solvents, degreasing agents, acids, and alkalines. It has tensile strength superior to high density polyethylene. It is has a low moisture absorption rate, is resistant to staining, and is very light weight.

Roof Gradient

Problems

Solutions

Very Steep

>20° (>36%)

· Very high runoff due to gradient

· Dry at top and wet at bottom of slope

· Risk of sliding of green roof materials

· Drain layer is generally not necessary

· Use thin profile drains (0.25”) if needed

· Secure drainage layer to prevent sliding
