A range of water swellable polymeric hydrophilic waterstops for sealing construction joints in in-situ concrete.
The Supercast SW range consists of swellable waterstops, formed sections, SWX gun-applied paste and SW adhesive.
Supercast SW sections are made from high performance synthetic elastomer strips. The swelling action of the Supercast SW range is the result of contact between water and hydrophilic groups which are an intimate part of the Supercast SW polymeric structure. These hydrophilic groups are not subject to extraction and loss of swelling performance by prolonged or repeated wetting. Expansion of the waterstop creates a positive pressure against the faces of the concrete joint, thus preventing water passing through the joint.
Supercast SWX is a grey, elastomeric water-swellable gun applied paste. It can be used as a swellable adhesive to adhere Supercast SW waterstop to concrete. It has the capability to fill undulations and surface holes in the concrete beneath the waterstop and swell into these when required.
