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 

Standards compliance
Suitable for use in contact with potable water Water Byelaws Scheme Approved product.

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. 

Water swellable - Basic Polymer - hydrophilic waterstop, where shown on the drawings, shall be made from a preformed elastomeric strip which can integrate into existing waterstop networks. It shall be free from rubber, bentonite or other inclusions. The waterstop shall have an unrestrained volumetric expansion of upto 300%. It must not deteriorate under prolonged wet/dry cycling. It must be able to withstand a hydrostatic head of 60 metres (6 bars). It shall be used in accordance with the methods given in the manufacturer’s current data sheet.

HDPE High-Density Polyethylene membrane is a type of synthetic material made from high-density polyethylene polymer. It is commonly used in a variety of applications due to its excellent chemical resistance, durability, and impermeability.
