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.

Tested
You 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).
The rolls can be moved by just 1 person to the right spot (by hand truck or by simply rolling). The rolls are immediately ready to install.
We supply our ND Drainage Systems as rolls. This means, that all three required system layers – protection layer, drainage layer and filter layer – are unrolled at once in one motion.
Unroll, overlap and done. Since all layers are glued together, delays due to wind effects or wrongly positioned layers are nearly impossible. It can’t be quicker.
Rock & roll
The ND Drainage Systems are easy and quick to install because the filter, drainage and (sliding and) protection layer are glued together. The ND Drainage Systems are supplied as rolls, making them easy to handle and quick to unroll.
Glued, not thermally bonded
The filter, protective (and slip) layers are glued and not thermally bonded to the core of the dimpled core. This prevents damage to the mechanical and hydraulic properties of the geotextiles and the entire drainage system. It also prevents that geotextiles form being pressed between the dimples, which could jeopardize good drainage. The overlap of the filter geotextile ensures optimal filtration.
