Permaroof Roofdrain is a lightweight water storage geocomposite primarily intended to solve dry spells in weather, ensuring your green roof system gets the water it needs for a long and healthy lifespan.

In addition to providing drainage the perforated roofdrain core provides a water reservoir for plant roots, storing between 4 and 20 litres per m2 and in turn aiding sustained growth during dry spells.

Permaroof Roofdrain attenuates the rainfall run off and is therefore an active SUDS system. This ability to control the discharge rate is key criteria in overcoming planning constraints. 915mm wide and sold by the linear meter up to a maximum of 50 linear meter long strips.
