Köster Quellband – Water bar

Hydrophilic Strip

Sodium bentonite based water swellable water bar

KÖSTER Quellband is a sodium-bentonite based water swellable water bar with an alkalinity activated surface coating which stops premature swelling of the tape on the building site.

Field of application
KÖSTER Quellband is used as a waterstop in concrete construction joints. The robust strip is simply nailed onto an existing joint face before the consequent concrete pour. Any leakage through the joint activates the KÖSTER Quellband. KÖSTER Quellband breaks down during the swelling process and the resulting paste seals all cracks and voids permanently.

Advantages

  • Alkalinity activated- stops premature swelling on contact with water
  • Easy application
  • No special tools are needed
  • Permanent seal of the joint after swelling – fills all voids and cracks in the concrete
  • Easy to use, non-sticky surface even at high temperatures
