ND 800sv Drainage System
High-performance, CE-marked drainage system for podium decks with limited fall, or podium decks where extensive drainage lengths are required on inverted roof constructions. The drainage system prevents the build-up of hydrostatic pressure on the waterproofing membrane and protects it against mechanical loads.
