Canzac SwellStop Waterstops

Product Description

Swellstop and Swellstop II are a flexible, coiled strip of butynol rubber and a swellable clay waterproofing compound that swells upon contact with water to form a long lasting compression seal in concrete joints.

Swellstop is a multiple use waterstop, which is formulated to encapsulate hydrophilic materials into a rubber base creating a controlled, moisture- activated sealant. Swellstop has the structural integrity of a rubber-based sealant, conforming well to the underlying substrate and exhibiting self-healing properties when needed. Unlike many of the traditional cly-based products, Swellstop will not expand to a point that thewaterstop itself is destroyed. The controlled expansion properties engineered into Swellstop reduce the internal pressures created in cast-in-place applications. Internal pressures can cause spalling in foundations and wall structures.
