AV 620 hd 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 an extremely high compressive strength and a construction height of approx. 12.5 mm. A special mono-filament woven geotextile is bonded to each dimple as a filter layer. A pressure-dividing slip film is glued to the back of the dimpled sheet and acts as the first smooth, non-sticky surface of the slip layer and as an additional protection layer of the waterproofing membrane. Application The AV 620hd Drainage System is a component of the Nophadrain Parking Deck System – heavy goods vehicles that acts as a filter, drainage and protection layer. Properties • Material dimpled sheet: recycled high impact polystyrene (HIPS) • Material woven geotextile filter: polypropylene (PP) • Material pressure-dividing slip film: polypropylene (PP) • Construction height: approx. 12.5 mm • Compressive strength: approx. 1,200 kPa • Deformation at 1 MPa: 9 % • Weight: ca. 1,407 g/m² • Drainage capacity at i = 1 at 20 kPa: approx. 5.36 l/(s.m) • Drainage capacity at 2 % fall at 20 kPa: approx. 0.74 l/(s.m) • Test: performance test at the Technical University Munich (D) - assessment of the performance and behaviour of a pavement structure under simulated traffic conditions.
