Drainage system ND 4+1h (37.5 m²) in package

Drainage system for flat roofs.

High-performance drainage system made of recycled, highly resistant "high impact" polystyrene (HIPS), with an innovative nub design and CE hEN 13252 marking. 

The core of the ND 4+1h drainage system is a perforated, vapor-permeable, studded foil with a water retention capacity of approximately 4.3 l/m². The core is characterized by high compressive strength and a profile height of approximately 17 mm. 

A black non-woven filtration geotextile is glued to the surface of the smooth side of the perforated core, and a white non-woven geotextile, which performs a vapor-permeable, protective and separation function, is connected to each nub on the reverse side of the film.

The ND 4+1h drainage system is part of the AGRO CS Extensive and Intensive Green Roof Systems. In these layers, it functions as a filtration, drainage and protective layer. The construction height of around 17 millimeters prevents the substrate from getting wet and the risks associated with freezing of the paving. This profile height also allows for larger distances required for surface drainage. It is suitable for both the “classic” warm roof structure and the inverted roof structure.
