Uses
The Supercast range of PVC waterstops is designed to provide an integral sealing system for movement and construction joints in concrete cast in-situ. These joints typically occur in the following types of structure:
Water Retaining
- Reservoirs, water towers and sewage tanks
- Dams, culverts, canals and spillways
- Swimming pools
- Bunded areas surrounding liquid retaining tanks
Water Excluding
- Basements and underground car parks
- Tunnels and subways
- Abutments and retaining walls
- Roof decks and podium areas
Application Notes
- When used on ground slabs where the waterstop is supported on blinding, Rearguard profiles usually require no fixing
- Lay the waterstop centrally over the line of the joint to be formed
- Fixing to vertical shuttering is done by nailing through the outer
- nailing flanges leaving the head of the nail proud so that it is held in the cured concrete
- This prevents the waterstop being displaced when the shuttering is struck
- Jointing of Supercast waterstops is carried out using Fosroc Heat Welding Equipment and Supercast Jig
- Standard intersection pieces are available for each Supercast waterstop profile
Precautions
- Hot weld site jointing of PVC waterstops liberates hydrogen chloride mist and vapour
- Ensure adequate ventilation
- If working in still air or confined spaces, provide forced ventilation or suitable respiratory protective equipment
- Care in the handling and installation of Supercast PVC waterstops is necessary at low ambient temperatures. Such temperatures will also require special precautions to be taken with the placing and curing of concrete
