ND 600sv / ND 600hdsv Drainage System
High-performance, CE-marked drainage system with very high compressive strength, a perforated core and a special mono-filament woven geotextile. Specially suited for installing pedestrian and vehicular pavements on sub-base layers made of rubble and permeable concrete on an inverted roof. The drainage system prevents the build-up of hydrostatic pressure on the waterproofing membrane. The vapour-permeable geotextile on the back protects the XPS insulation from mechanical loads and ensures that vapour is able to evaporate freely from the XPS insulation. It's a 3-in-1 product (on roll) consisting of a woven filter geotextile and a vapour-permeable geotextile that are glued (not thermally bonded) to the dimpled core.
