AV 600sv 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 perforated, vapour-permeable dimpled sheet with a very high compressive strength and a construction height of approx. 13 mm. A special mono-filament woven geotextile is bonded to each dimple as a filter layer. A vapour-permeable geotextile is glued to the back of the dimpled sheet as a separation and protection layer of the XPS insulation panels. Application The AV 600sv Drainage System is a component of the Nophadrain Parking Deck System – cars that acts as a filter, drainage, protection and separation layer on an inverted roof construction. Properties • Material dimpled sheet: recycled high impact polystyrene (HIPS) • Material woven geotextile filter: polypropylene (PP) • Material vapour-permeable geotextile: polypropylene (PP) and polyethylene (PE) • Construction height: approx. 13 mm • Compressive strength: approx. 900 kPa (AV 600sv) • Perforations/m²: approx. 1,540 / ø 6.3 mm • Weight: approx. 1,264 g/m² (AV 600sv) • Drainage capacity at i = 1 at 20 kPa: approx. 5.27 l/(s.m) (AV 600sv) / 5.36 l/(s.m) (ND 600hdsv) • Drainage capacity at 2 % fall at 20 kPa: approx. 0.72 l/(s.m) (AV 600sv) • Test: performance test at the Technical University Munich (D) - assessment of the performance and behaviour of a pavement structure under simulated traffic conditions.
