Where is Supercast Hydrofoil PVC waterstop used?

It seals expansion and construction joints in cast in-situ concrete on water-retaining and water-excluding structures such as tanks, basements, retaining walls and below-ground slabs.

How is the 250 mm waterstop installed?

The waterstop is cast into the joint with one half embedded in the first pour and the second half captured by the next pour. The eyeletted flanges allow positive fixing to formwork or reinforcement before concreting.

How much does one roll cover?

Each roll is 12 m long. Allow a small overlap and order moulded intersection pieces (Tees, 3- and 4-way, MOEs, MOFs) for changes of direction rather than site-fabricating them.

Is Supercast suitable for drinking water structures?

Yes. The system complies with AS 4020:2018 for products in contact with drinking water, so it can be specified in potable water tanks and reservoirs.

How are lengths joined on site?

Lengths are heat-welded on site using a hot knife or jointing iron, following the Fosroc Supercast jointing instructions. Pre-fabricated intersection pieces remove the need to weld complex shapes in the field.

Product Details

Designed with precision, these waterstops ensure effective sealing to prevent water ingress and enhance structural integrity. With a length of 12 meters and a width of 250mm, these PVC waterstops are durable, flexible, and easy to install. Parchem Hydrofoil Supercast PVC waterstops are the ideal choice for reliable waterproofing in various concrete applications, providing long-lasting protection against water leaks and ensuring the durability of your construction projects.

How to Use

Fix centrally over the line of the joint through the edge flange eyelets, then place and fully compact the concrete around it.Select the waterstop width for the concrete thickness; the 250mm profile suits wall thicknesses of 250mm and over
Carefully measure the length of waterstop required and add 5 or 6 mm to each mating end to allow for melting during heat welding
Clamp the end to be trimmed into a jointing jig and cut to the required length using the side of the jig as a guide
Repeat for the other mating end
Clamp the two ends into their respective sides of the jig with approximately 10 mm projecting and engage the guide rods
Plug in the 240v welding blade, allow it to warm up and check on a small offcut that it reaches a temperature sufficient to melt the PVC
Press the mating ends against either face of the blade until a molten bead of PVC approximately 3mm thick appears along the length of the blade
Slide the jig apart, remove the heating blade and push the waterstop back together under pressure so the molten PVC fuses
Unclamp the jigs and remove the joined waterstop without flexing the join until it has cooled
Use the factory moulded intersection pieces at tees, corners and changes of direction rather than site fabricating them
Lay the waterstop centrally over the line of the joint, within the thickness of the concrete
Fix through the eyelets, which are located outside the edge bulbs so no water path is created around the profile
Hold the waterstop securely in correct position while the concrete is placed
Leave adequate clearance where reinforcement is present to permit proper compaction
Fully compact the concrete around the waterstop so no voids or porous areas remain

Parchem Supercast Hydrofoil 250mm x 12m $556.00

Technical overview

Supercast Hydrofoil is a centrally placed PVC waterstop extruded from a high grade PVC compound formulated for flexibility and longevity, supplied by Parchem under licence from Fosroc International. It is cast within the thickness of the concrete over movement and construction joints, so it is supported by concrete on both sides and resists water pressure from either side, which is what makes it suited to water retaining structures. The fully continuous 4 bulbed section works on both the valve and tortuous path principles, and the eyeletted edge flanges sit outside the edge bulbs so fixing does not create a water path. It handles hydrostatic head up to 60 m and joint movement up to 10 mm, and holds an accredited AWQC report (308921) for AS/NZS 4020-2018 compliance for contact with drinking water.

Key applications

Movement and construction joints in concrete cast in-situ
Reservoirs, water towers and sewage tanks
Dams, culverts, canals and spillways
Swimming pools
Bunded areas surrounding liquid retaining tanks
Basements and underground car parks
Tunnels and subways
Abutments and retaining walls
Roof decks and podium areas

Surface suitability

Cast in-situ concrete movement and construction joints
Walls 250mm thick and over (250mm waterstop width)
Water retaining structures - reservoirs, water towers and sewage tanks
Water excluding structures - basements and underground car parks

Supercast Hydrofoil is a centrally placed waterstop: it must sit within the thickness of the concrete and be supported by concrete on both sides. The 250mm width suits wall thicknesses of 250mm and over; for concrete less than 250mm thick use a narrower waterstop approximating to the wall thickness. Waterstops must be installed so they are securely held in correct position while concrete is being placed, and the concrete must be fully compacted around them to ensure no voids or porous areas remain. Where reinforcement is present leave adequate clearance to permit proper compaction. Do not bend tighter than the minimum practical placement radius of 15 m on flat or 0.15 m on edge or distortion is likely, and note ambient temperature may affect these dimensions. Site joints must be heat welded with the correct jig and a 240v blade. Ensure heater blades are earthed by the green/yellow wire and that the wiring operation is carried out by a competent electrician. Hot blade, do not immerse blade in water or liquids.
