Retention basin recovered with GRP lining

A retention basin, in which rain and surface water is to be collected, was completely lined with GRP laminates from Haase. Both the price and the durability of the material were decisive for the customer’s decision.

The approx. 186 m² laminate was manufactured in the Großröhrsdorf plant, assembled to the correct size and then wound up as rolls. The transport to the construction site was not a problem. The GRP panels were anchored to the concrete and then all joints and panel transitions were overlaminated in a liquid-tight manner. This technology also enabled the absolutely tight connection of a DN250 inlet pipe using a GRP pipe socket and a rubber press seal. Finally, a UV-resistant protective coating was applied.
