The brochure lists natural rubber and synthetic rubbers, compounded, milled and moulded or extruded, then vulcanised. It highlights elasticity, abrasion resistance, ageing resistance, tear resistance, and the ability to follow movement.
The stated service window is −45 °C to +60 °C. The brochure says not to use a rubber waterstop above 70 °C, in strong oxidation, or where oils and other organic solvents will reach it.
What the brochure emphasises
- CB: buried, with a centre hole. CP: buried, without a centre hole.
- EB: external, with a centre hole. EP: external, without a centre hole.
- Compounds named: natural rubber, chloroprene, EPDM.
- Also: steel-edge, hydrophilic (water-swelling), and flat profiles.
Uses named in the brochure
- Construction joints and movement joints in cast-in-place concrete.
- Basements, tunnels and culverts, aqueducts, dams and liquid-retaining structures.
- External basement walls and post-poured strips are named as everyday uses.
Laying notes printed in the brochure
These are the manufacturer’s notes. They do not replace the project specification or the engineer’s method statement.
- Do not leave the profile in the sun for long, keep it out of rain, and keep it away from aggressive chemicals.
- Protect it from reinforcement and from machinery. A tear in rubber propagates more easily than a tensile break.
- Fix it so the pour cannot move it. The brochure allows extra reinforcement, a dedicated clip, or tie wire and formwork. If you must puncture it, puncture only the fixing edge.
- Order the length from the drawings, with sketches for junctions, and have the factory join it where you can. Site joints are vulcanised on a heated platen or cold-bonded for rubber, and welded for a plastic waterstop.
