Koster Quellband Waterbar (Box 6 x 5m rolls)

Koster Quellband is used in waterproofing systems as a waterstop in concrete construction joints in new build basement and retaining wall structures.

The robust strip is simply nailed onto an existing joint face before the consequent concrete pour. Any leakage through the joint, activates the Quellband, which expands to fill any cavities in the joint to stop water leaks.

Quellband is a sodium-bentonite based water swellable joint tape with an alkalinity activated surface coating which stops premature swelling of the tape on the building site, which breaks down during the swelling process and the resulting paste seals all cracks and voids permanently.

Koster quellband can be fixed in place by a combination of mechanical fixings – eg hilti gun – and CEM805 adhesive.
