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, heavy duty but lightweight spacer element made of thermoformed polypropylene. Height: ca. 65 mm or 100 mm; integrated void system; max. water retention
volume: ca. 60 l/m² . Compressive strength according to EN ISO 25619-2: 50 t/m²; for
use in Stormwater Management Roofs on roof surfaces without inclination with heavy
loads such as walkways or driveways or deep substrate levels on top.
