Koster Quellband - Water Swellable Joint Tape
Verified by manufacturer 3 months ago
Sodium bentonite-based water swellable joint tape.
Application
Can be used in horizontal and vertical joints.
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 product and breaks down during the swelling process with the resulting paste sealing all cracks and voids permanently.
Description

Features and benefits:
- 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.
