Long product description

Water storage and retention element made of polypropylene for surface drainage and water buffering used in the Nophadrain Systems for extensive green roofs. They serve as temporary storage of excess rainwater to relieve the storm water system. Due to the special design, the water retention elements can also be used on inverted roofs. The elements can be combined with flow restrictors for the suitable regulation of drainage (e.g. ND AFC-100 Adjustable Flow Control).

For protection of the waterproofing membrane or the thermal insulation, ND SV 300 Protective Geotextile has to be placed underneath the ND WSE-100lte. As filter layer, the ND FV-300 Filter Geotextile has to be used.

Accessories
The ND WSE-100lte Water Retention Systems need to be interlocked with special connectors (type Large) in order to assure best force transmission. Recommended quantity: 6 connectors per m2 (available per bag (50 pieces)).
