Trafficable roofs

With our trafficable roof systems, we transform gray roofs of underground structures and parking garages into walkable and trafficable public space.

To prevent structural damage to a paved area on the roof, it is important that the drainage system is strong and designed to withstand mechanical loads as well as the impact of water. Poor drainage and insufficient slope can lead to water stagnation on the roof. This can destabilize the subsurface and soil layers, cause frost damage to the paving or cause unwanted hydrostatic pressure on the waterproofing membrane. Therefore, a reliable and suitable drainage system is essential for the design of trafficable roofs.

The core of the Nophadrain Trafficable Roof Systems consists of the drainage systems from the ND 200 series (walkable roofs) and the ND 600 series (trafficable roofs).

The powerhouses among drainage systems

The drainage systems of the ND 200 series, such as the ND 220 and ND 200sv Drainage Systems, have a compressive strength of 700 kPa and always consist of three functional layers that come together in one product: a filter layer, a drainage layer and a protective layer. However, the real powerhouses are the drainage systems from our ND 600 series, such as the ND 620 and ND 600hdsv Drainage Systems. Drainage cores with extremely high compressive strengths of approximately 900 kPa or even 1,200 kPa characterize them. This makes them suitable for load classes N1, N2 and N3.

Robust filter geotextile key to success

In addition to excellent compressive strength, all drainage systems of the ND 600 series are equipped with a special CE-marked monofilament filter geotextile. This geotextile combines high puncture resistance with minimal stretch, so that the static and dynamic loads released during traffic activities do not cause damage to the filter layer. This also applies during installation work, such as vibrating the foundation layer with a vibrating plate. The filter fabric won’t be damaged, so the drainage layer cannot become clogged and drainage capacity is guaranteed.

The strength and stability of this series of drainage systems has proven itself not only in numerous projects, but also in long-term tests at various institutes such as the University of Munich.
