Centrally and externally placed PVC
waterstops

The Supercast range of PVC waterstops is designed to
provide an integral sealing system for movement and
construction joints in concrete cast in-situ.

Centrally placed Sika® Waterbars O type section is used in expansion, contraction and construction joints. The bulb in the centre allows for movement in the structure to be accommodated for. The waterstops are easily anchored to the steel reinforcement using special tie-clips.

The externally placed rearguard Sika® Waterbars AR sections are used in construction and contraction joints. The centrally placed fin assists with shutter locations

The externally placed rearguard Sika® Waterbars DR sections are
designed with a flat top box section, with a protruding fin, to assist with positioning and to provide a chair to support the joint filler. The section is used in expansion joints to accommodate movement.
