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 Advantages „ Range of profiles to suit every need „ Fully continuous 4 bulbed network „ Eyeletted edge flanges for positive fixing „ Simple on-site jointing „ Full range of moulded and fabricated intersection pieces „ Complies with AS 4020 Standards Compliance Supercast PVC complies to BS 2571 - 1990, Class 3, Type E3. Description Supercast waterstops are extruded from a high grade PVC compound which has been formulated to give excellent flexibility and longevity characteristics. They are available as straight lengths and factory produced intersections or as a factory prefabricated segment of a network to minimise site jointing. The range consists of centrally placed profiles; Supercast Hydrofoil and externally placed profiles; Supercast Rearguard S, Supercast Rearguard R. Principles of waterstop function Supercast waterstops work because of two specific aspects of their design. a) Valve principle Simple waterstop profiles based on dumbells are cast into the edges of adjacent concrete panels which act as baffles. In the event of joints opening as drying shrinkage or other movement occurs, the edge bulbs of the profile act as anchors. These induce tensions across the waterstop resulting in a sealing effect at the inner faces of the edge bulbs. b) Tortuous path principle Profiles with more complex cross section have a much greater surface area. They present a much greater resistance and more difficult path for water to seep around the section. The Supercast range incorporates both of these principles. The products offer a fully continuous 4 bulbed design maintaining both the valve and tortuous path principles. These principles area maintained in the transition from Rearguard profiles in floors to centrally places profiles in walls. Supercast Hydrofoil sections Centre bulb sections are used in expansion, contraction and construction joints. The centre bulb allows for movements in a structure to be accommodated whilst its hexagonal design provides a flat surface. This allows shuttering and joint fillers to fit snuggly.
