Smart systems for green and utility roofs
High-performance, CE-marked drainage system with very high compressive strength 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. The drainage system prevents the build-up of hydrostatic pressure on the waterproofing membrane and protects it against mechanical loads. It's a 3-in-1 product (on roll) consisting of a woven filter geotextile and a pressure dividing slip film (ND 620hd) that are glued (not thermally bonded) to the dimpled core.
