Studded drainage membrane RS 60

polyolefingreen roof drainagedrainage

With this system build-up ZinCo offers a solution for the increasing heavy rain events and the resulting overload of the sewer systems. Spacer elements, combined with a Retention Run-off Limiter installed on top of roof drains, allow for additional water storage on the roof without affecting the upper layers (vegetated green roofs, walkways, driveways, etc.). The retained precipitation is then released with a delay over a pre-defined period of time into the sewer systems. The system build-up “Stormwater Management Roof” combines the advantages of a green roof with effective stormwater management. The system build-up is suitable for application on roofs without slopes. Powerful and highly transportation friendly spacer element made of thermoformed recycled polyolefin; height: ca. 60 mm; weight: ca. 2.2 kg/m²; with multidirectional drainage channel system on the underside and interlocking studs for length- and crosswise connection; max. water retention volume: ca. 55 l/m²; compressive strength at 10 % compression according to EN ISO 25619-2: ca. 40 kPa, for use in Stormwater Management Roofs on roof surfaces without inclination.
