Smart systems for green and utility roofs

High-performance, CE-marked drainage system for podium decks with sufficient fall. The ND 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 filter geotextile and a pressure dividing slip film (ND 220) that are glued (not thermally bonded) to the dimpled core.
