SWELLABLE WATERSTOPS FOR IN-SITU CONCRETE
Description
The Supercast SW range consists of three swellable waterstop strips, Supercast SWX gun-applied paste, Supercast SW Adhesive and Nitoseal PU40A.
Supercast SW strips 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. Supercast SWX 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. Please refer to separate datasheet.
Uses
Integral sealing for construction joints in concrete cast in-situ.
Convenient and problem solving in situations where a conventional waterstop would require complex shuttering.
Typical uses include secant piled and diaphragm walled basements, pile caps and casting against old concrete. The Supercast SW range can provide simple solutions to detailing pipe entries, construction joints in the vertical plane and to kicker joints.
They can be linked to Supercast PVC waterstops to give an effective combination of waterstops which maintain network continuity.
Characteristics & Advantages
