Suitable for use in contact with potable water – Water Byelaws Scheme Approved product: Listing No. 9312507.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.
Aquaproof Anchoring Systems is authorised project Super stockist and brushbond authorised Fosroc applicator for Fosroc Chemicals(India) in Pune, Maharashtra and a leading dealer for construction chemicals.


Integral sealing for construction joints in concrete cast in-situ where conventional waterstops are impractical to use because of limited access.
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.
