Protective layer on a plastic sealing

The construction measures in the industrial area of Zwickau led to a large-scale sealing of the surfaces.

The soil sealing had a negative impact on the natural water cycle, with the result that precipitation could no longer seep away naturally, but had to be drained from the sealed surfaces and temporarily stored to relieve the sewer system. The drainage concept provided the construction of a rainwater retention basin as part of a storm water management system.

After the basin had been excavated, a protective non-woven fabric was laid first and then a plastic sealing membrane was laid on top to seal the basin. TILTEX 9 P roll was laid as a stable
protective layer on top of the plastic sealing membrane. It was prefabricated at the factory in different lengths for precise laying at the construction site.

For the project described here, TILTEX 9 P was the technically, and above all, economically optimal solution for stable protection against mechanical damage to the plastic geomembrane. For TILTEX 9 P, a "normal concrete" of strength class C80/95 is used. Typical areas of application are, for example, surface erosion protection in open-cast mines for the drainage of surface water, lining of trenches of any kind and excavation pit protection as an alternative to sheeting covers, shotcrete, etc. The spectrum of applications ranges from road construction, ditch construction and hydraulic engineering to the construction of reservoirs and rainwater retention basins.
