KISCOTE RW 10 is a pale-coloured rubber waterstop made of butyl materials. It swells rapidly when immersed in water, making it an obvious choice as a pre-installed defense against water leakages along construction joints for poured in-situ concrete. To prevent premature expansion before the next pour of concrete, it has been treated with a protective coating so it will not react for the first 1-2 hours of full contact with water. KISCOTE RW 10 reacts to water ingress rapidly – expanding over 100% by the first 20 hours of immersion in water. In addition, it has exhibited an ability to expand repeatedly after numerous wet-dry cycle conditions while still maintaining its functionality. It is installed by being nailed to one side of the concrete or glued using appropriate adhesives.

• Built-in delay-reaction coating to prevent premature swelling.
• Easy to install.
• High swelling > 250%.
