Enkadrain 3801 AKA XF 3801- Thin Drainage For Under Rooftop Pavers, Green Roofs

Looking for a drainage mat that will lay flat, resist UV degradation for up to 30 days, and is about 30% thinner than other mats on the market, and is suited for rooftop pavers, green roofs, plaza decks for starters?

Enkadrain 3801/ XF 3801 is a new thin drainage composite which is part of the Enkadrain family of environmentally conscious products. It consists of a post-industrial recycled white polypropylene drainage core and a very strong but lightweight white Colback filter fabric thermally bonded to one side and a grey Colback fabric bonded to the other . The U groove entangled filament configuration is protected from UV degradation for up to 30 days. This product, because it has 40% post-industrial recycled content, can help contribute up to 2 LEED points when used in conjunction with other recycled content products. Enkadrain 3801 can contribute towards additional LEED points when used with a green roof by reducing stormwater runoff, heat islands and energy consumption

Roof Gradient for Enkadrain 3801 on Sloped Roofs

ROOF GRADIENT PROBLEMS SOLUTIONS

Steep

5-20° (9-36%)

Very Steep

>20° (>36%)

· Runoff increases with roof gradient

· Water runs off too quickly on steep slope, growing substrate can become dry especially near the top of the roof

· Risk of sliding of green roof materials on the roof at high gradients

Drain layer is generally not necessary
Use thin profile drains (0.25”) if needed
Secure drainage layer to prevent sliding

· Use thin profile Enkadrains (0.25”) to slow down runoff and allow time for the rain to soak into the growing substrate

· Use EnkaDrain&Retain to retain water and compensate for higher runoff

· Install Enkadrain upside down or use one with 2-sided fleece to minimize sliding on steep slope roof

When to use a Drainage Mat

Drainage mats are used to provide drainage, soil separation and protection. The ideal mat must be lightweight, especially when they are going on green roofs, and rooftops. The thinnest, lightest material that doesn't store water is a must. Drainage mats often have to work with uneven surfaces, to help drain rainwater. Check for the manufacturers performance guarantee. Does it offer a 20 year performance guarantee?
