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.
Supercast SW20 can provide simple solutions to detailing pipe entries, construction joints in the vertical plane and to kicker joints. Can be linked to Supercast PVC*† waterstops to give an effective combination of waterstops which maintain network continuity. 

Advantages

 Easy to install
 Supercast SWX*† swellable adhesive enable full integration of Supercast SW20 and Supercast PVC networks
 Solves detailing problems in conjunction with Supercast PVC range
 Swelling properties unaffected by long term wet/dry cycling
 Delayed swell action allows extra tolerance on site
 Sustains effective seal in wet conditions

Description

The Supercast SW20 is a swellable waterstop which can be installed and positively linked into conventional Supercast PVC waterstop networks.This allows the use of Supercast PVC for expansion joints and Supercast SW20 for construction joints all the time maintaining an integrated network. The Supercast SW20 is made from high performance synthetic elastomer strips. The swelling action is the result of contact between water and hydrophilic groups which are part

of the Supercast SW20 ‘Basic Polymer’ molecular structure.


The hydrophilic groups are not subject to extraction or loss of swelling performance by prolonged or repeated wetting. This is a unique feature of the basic polymer. Expansion of the waterstop creates a positive pressure against the face of the concrete joint, thus preventing water passing through the protected joint
