StormCap™+Detention: How does it work?


StormCap™+Detention provides retention and detention.

Watch the video to see how StormCap™+Detention vegetated roof, a full-fledged stormwater tool, is ready to face second day and extra-large storms.

Superior Components

The engineered base layers include Urbanscape’s needled mineral hydro blanket, made solely of virgin rock fibre. This mineral wool has no binders and therefore has superior retention of 90% of water by volume and withstands freeze/thaw cycles.

A clear return on investment, it reduces or eliminates cisterns and bioretention facilities and frees up valuable space for income-generating development. Even works on a low-sloped roof!
