Supercast SW20
Water swellable – Basic Polymer – hydrophilic water stop,where shown on the drawings, shall be made from a preformed elastomeric strip which can integrate into existing water stop networks. It shall be free from rubber, bentonite or other inclusions. The water stop shall have an unrestrained volumetric expansion of upto 300%. It must not deteriorate under prolonged wet/dry cycling. It must be able to with stand a hydrostatic head of 100 metres (10 bars). It shall be used in accordance with the methods given in the manufacturer’s current data sheet.
Description
Uses
Integral sealing for construction joints in concrete cast in-situ where conventional water stops are impractical to use because of limited access.
Convenient and problem solving in situations where a conventional water stop 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*† water stops to give an effective combination of water stops which maintain network continuity.
