High-quality, CE-marked drainage system with high compressive strength consisting of a specially woven monofilament filter layer and strong drainage core. The ND Drainage System prevents the build-up of hydrostatic pressure against the waterproofing membrane and protects it against mechanical loads. This drainage system is especially suitable for installing walkable and trafficable paving on foundation layers of landfill material and drain concrete.
The special monofilament fabric combines high puncture resistance and minimal stretch, which can withstand the forces caused by static and dynamic loads from traffic. This also applies during installation because the filter fabric can also withstand the stresses of mechanical or dynamic compression of the foundation layer by means of a vibrating plate. This ensures that the filter geotextile is not punctured and the drainage layer remains free of additional filler material. The powerful drainage core with a compressive strength of approx. 900 kPa ensures that the drainage system retains its shape and therefore its original building height, even under dynamic loads. The pressure-dividing slip film, in combination with the ND TSF-100 Slip and and Protection Sheet, forms a double sliding layer that protects the roof covering against dynamic and static loads on traffic roofs.

TestedYou can request a test report from us about the functionality and stability of the system under dynamic loads. This practical research was carried out by the Technical University of Munich (DE). This practical research was carried out by the Technical University of Munich (DE).
The rolls can be moved to the right place by just 1 person (with a trolley or by rolling). Divide the rolls and install.
ND drainage systems are supplied in rolls. With one motion, 3 layers are rolled out at once.
Roll out, overlap and done. Bonding the layers means there is no delay caused by wind, everything is in the right place at once.
Rock & roll
The ND Drainage Systems are quick and easy to install because the filter, drainage, and (sliding and) protective layers are bonded together. De ND Drainagesystemen worden op rol geleverd en zijn daardoor makkelijk te hanteren en snel uit te rollen.
Bonded, not thermally bonded
The filter, protection (and sliding) layers are bonded and not thermally bonded to the core of the dimpled membrane, to prevent damage to the mechanical and hydraulic properties of the geotextiles and the entire drainage system. Bovendien voorkomt dit dat de geotextielen tussen de noppen gedrukt worden, wat een goede drainage zou belemmeren. De overlap van het filtergeotextiel zorgt voor een optimale filtratie.
