Fosroc Supercast SW20 PVC Waterstops

High performance swellable waterstop for in-situ concrete.

Uses

Integral sealing for construction joints in concrete castinsitu.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. Fosroc 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.

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.

Design criteria

Fosroc Supercast SW20 should be used to prevent the passage of water through non-movement joints in both new in-situ concrete. and between new and existing concrete. Supercast SW20 increases in volume in the range of up to 300% and gives a resistance to hydraulic heads of up to 60 meters. Swelling ofFosroc Supercast SW20 in fresh concrete is minimal, therefore maximizing the positive pressure to seal the joint. Supercast SW20 is suitable for application between existing and newly placed concrete where there is little or no steel continuity and where up to 2mm movement may occur. Supercast SW20 waterstops should be positioned to ensure that a minimum of 80 mm cover of concrete is present to accommodate pressure developed during the swelling process.
