New joint sealing system provides for high securityin groundwater under pressure


In the field of house and apartment construction, Klaus Hufnagl Betonwaren GmbH uses its own proprietary manufactured precast solid wall elements, from the foundation slab to the roof ridge. The company has decided in favour of the system by B.T.innovation from Magdeburg for the implementation of the cellar. The ‘white tank’ is used here, or rather the ‘zebra sealing’, i.e. the joints are subsequently sealed from the outside with a film strip that is approved for this purpose and has been tested by the building authorities. A pressure water seal of up to 20 m water column is thus achieved with InnoElast and ProElast.
