Drainage system ND 5+1 (25 m²) in package

Drainage system for flat roofs.

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

The core of the ND 5+1 drainage system is a perforated, vapor-permeable, studded foil with a water retention capacity of approximately 5.8 l/m². The core is characterized by high compressive strength with a profile height of approximately 27.5 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 foil.

The ND 5+1 drainage system is part of the AGRO CS Extensive and Intensive Green Roof Systems. In these layers, it performs the function of a filtration, drainage and protective layer. The ND 51 drainage system is suitable for installation in layers of green roofs with insufficient slope of the structure. The construction height of around 28 mm 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 the "classic" warm roof structure as well as for the inverted roof structure.
