The Nophadrain Parking Deck System-HGV has been extensively subjected to performance tests by the Technical University in Munich. In particular, loading areas for heavy goods vehicles and emergency vehicles zones (fire engines, ambulances, etc.) are exposed to high dynamic and static (traffic) loads. The pressure resistant CE marked ND 620hd Drainage System ( approx. 1,200kPa ) in combination with the ND TSF-100 Slip and Protection Sheet offer an excellent protection for the waterproofing membrane. The sub-base layer, which is installed directly on top of the drainage system, can therefore be compacted properly creating a suitable base for the paving elements. The Nophadrain Parking Deck System can be easily combined with intensive planting schemes.
