ND SolarDrain

High-quality, CE-marked drainage system for roofs equipped with extensive vegetation in combination with the ND Solar Mounting System for Green Roofs. It is suitable for roofs with a standard fall, with unlimited fall and for both standard roof constructions as inverted roof constructions. The drainage system consists of a filter geotextile, perforated drainage core with water buffering and a GRK 4-class separating geotextile. It prevents the build-up of hydrostatic pressure against the waterproofing membrane and protects it from mechanical loads.
