HIGH SWELL HYDROPHILIC WATERSTOP FOR IN-SITU CONCRETE
Description
Supercast SW30 is a swellable waterstop that can be installed and positively linked into conventional Supercast PVC waterstop networks.
Supercast SW30 is made from high performance synthetic elastomer strips. The high swelling action is the result of contact between water and hydrophilic groups which are part of the Supercast SW30 ‘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.
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.
