Fosroc Waterstops Supercast is a swellable waterstop for use with sealing construction joints, it can be installed and positively linked into conventional Supercast PVC waterstop networks. This product is made from high performing elastomer strips that swell when in contact with water. The hydrophilic groups are not subject to extraction or loss of swelling performance by prolonged or repeated wetting. This swelling means that the waterstop pushes against the concrete joints, stopping any water from getting through. This swelling action happens because of the hydrophilic particles that interact with water and draw water to it. This productís unique formula means that it does not lose any performance or swelling through repeated wetting. Use Fosroc Waterstops Adhesive Supercast to fix the Fosroc Waterstops Supercast to concrete. For any more advice or guidance, call our team on 01628 674910.
