The Enkadrain 3000R series is Colbond's family of environmentally conscious composites made of post-industrial recycled polypropylene drainage core and a geocomposite fabric bonded to one or both sides.
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.
EnkaRetain & Drain 3111/3211 is an all-in-one drainage/water retention layer that combines Enkadrain 3611R with a super absorbent water retention fabric that holds 10x its weight in water. The fabric absorbs water for continuous hydration of plant roots, while excess water passes through to the drainage core below. 3211 is the basic 3111 but also has a Colback nonwoven fabric bonded to one side which gives added protection to the waterproofing membrane.
Enkadrain 3611R/3811R is the classic waffle pattern Enkadrain with Colback nonwoven fabric bonded to two sides. The smooth, touch bolback fabric protects the waterproofing membrane and eliminates the need for a protection board.
Enkadrain/W 3601 is the most recent addition to the 3000 series. It is a thin, white polypropylene with a very strong but lightweight white Colback filter fabric thermally bonded to one side.
