AV WastoDrain

The WastoDrain system for green roofs is a water storage system as well as a long-lasting drainage system with a highly diffusion capability. It provides thereby the best conditions for long lasting roof greening. With bearing capacity up to 204 kN/sqm, the Wasto-Drain roof water storage panels are easier to be installed and are suitable for higher substrate layers. The drain-age system have 277 holes/sqm and enables water retention of approx. 27 l/ sqm. WastoDrain improves the green roof microclimate.
