Inspection Concrete cladding

In order to permanently protect concrete against chemical deterioration, concrete structures are coated with a concrete protective or liquid-retaining layer. Concrete cladding prevents the action of gases and/or aggressive liquids and is used, for example, in waste water basins of WWTP’s or other storage tanks. Normec QS assesses the welds and checks whether the result meets the requirements.

Inspection of concrete cladding during construction and leak tightness investigation

Integrated application of HDPE linings in concrete structures are processed in accordance with the “Protocols for the application of plastic geomembranes for soil protection”. Both during and after the weldingwork, the welds are assessed and it is checked whether the result meets the set requirements.

Normec QS carries out the following inspection activities in this context:

  • assessment of the welding methods to be used
  • assessment of the welders to be used
  • assessment of the welding process before and during the execution of the welding work
  • verification of the result by visual inspection
  • leak tightness test (with the vacuum or with the spark test method).
