AV 200h Drainage System

High-performance CE-marked drainage system with an innovative dimple design made out of recycled high impact polystyrene. The core of the AV Drainage System is a dimpled sheet with a high compressive strength and a construction height of approx. 16 mm. A non-woven geotextile is bonded to each dimple as a filter layer. Application The AV 200h Drainage System is a component of the Nophadrain Podium Deck System that acts as a filter, drainage and protection layer. The drainage system is designed for roofs with limited falls. The increased construction height (approx. 16 mm) prevents waterlogging in the sub-base and /or levelling layer and the risk of frost heave affecting the paving and allows longer drainage length.
