Waterproofing and tiling in wastewater treatment plants

Concrete surfaces in wastewater treatment plants are permanently subjected to chemcal, biological and mechanical stresses. Areas with vehicular traffic are also subjected to heavy duty stresses and as a rule fitted with wearing tiles. For this reason, there are intense demands on the waterproofing and installation systems.

When levelling is required a cement replacement system can be used together with a bonding agent

Alternatively a bonded screed together with a bonding slurry can be installed


Epoxy resin-based barrier primer


The waterproofing is carried out with different colours of the chemically resistant polyurethane waterproof membrane ASOFLEX-AKB with ASO-Joint-Tape-2000-S. The last coat is sanded with quartz sand.
