Specification of Fosroc Supercast SW
Swellable waterstops for in-situ concrete
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
appropriate effective combination of waterstops which maintain
network continuity.
Advantages
Easy to install by adhesive bonding, or casting into joint
faces
Supercast SWX enables full integration of Supercast SW
and Supercast PVC networks
Supercast SW Adhesive and Supercast SWX can be
applied to damp substrates
Solves detailing problems in conjunction with Supercast
PVC waterstops
Swelling properties unaffected by long term wet/dry cycling
Tolerant of salts in concrete and groundwater
Sustains effective seal in wet conditions
Highly adaptable to accommodate complex joint shapes
Description
The Supercast SW range consists of swellable waterstops;
Supercast SW formed sections, Supercast SWX gun-applied
paste and Supercast SW Adhesive.
Supercast SW sections are made from high performance
synthetic elastomer strips. The swelling action of the Supercast
SW range is the result of contact between water and hydrophilic
groups which are an intimate part of the Supercast SW
polymeric structure. These hydrophilic groups are not subject
to extraction and loss of swelling performance by prolonged
or repeated wetting.
