INTERNATIONAL PROFILES CHEMICAL RESISTANT WATERSTOP
Sure-Shield® TPER (Thermoplastic Elastomeric Rubber) Waterstops lead the way in high technology waterstops that have been designed for use in primary and secondary containment structures where a highly chemical resistant waterstop is required to prevent the flow or migration of fluid through joints in concrete.
Sure-Shield® TPER Waterstops are extruded from specially compounded cross-linked TPER material that resists a wide range of chemicals, oils, fuels, solvents, alcohols and aqueous acids, bases and salt solutions. Sure-Shield® TPER Waterstops provide high performance features for long-term durability and integrity of the structure, for continuous use in low and high temperatures and have excellent ozone and weather resistance.
Sure-Shield® TPER Waterstops are designed for use in many types of applications and structures, and are available in a number of different size profiles that are for use in construction, contraction or expansion joints.
Sure-Shield® TPER Waterstops are heat weldable and allow for fast and easy on-site welding/joining of the
The efficiency of any waterstop is very dependent upon good workmanship, installation, and on full compaction of the surrounding concrete around the waterstop during concrete placement. Optimum performance will be achieved if the waterstop is installed by keeping these important factors in mind.
- A full range of profiles and sizes to suit all construction requirements.
- High quality compounded TPER for long term durability and integrity.
- Excellent heat & ozone resistance.
- Internal profiles come with factory pre-punched eyelets for easy and secure wire tying to reinforcement.
- Ability to withstand high hydrostatic head pressures.
- Factory made intersections to simplify and minimise on-site fabrication.
- On-site welding equipment is available upon request.

PROFILE WIDTH SELECTION
The width of waterstop depends upon the thickness of the concrete and positioning of the reinforcement. The thickness of the concrete should be greater than or equal to the width of the waterstop profile. Refer to your engineer for further clarification and approval.
CJSA recommends the use of its specialised welding equipment for on-site welding which consists of thermostatically-controlled Welding Irons and special Welding Jigs (each type of CJSA Sure-Shield® TPER Waterstop requires its own welding jig to suit the particular shape). On-site joining is a simple exercise using CJSA Heat Welding Equipment comprising of an adjustable Welding Jig and Welding Iron.
The ends of the waterstop are cut square and placed into the adjustable Welding Jig, then push the ends of the waterstop against the Welding Iron and bring the two ends together until the molten ends of the Sure-Shield® TPER Waterstop fuse together. When ordering Welding Equipment, please advise profile number of the waterstop required.
FACTORY MADE INTERSECTIONS
A wide range of standardized prefabricated intersection pieces are available allowing easy site welding of butt joints to Sure-Shield® TPER Waterstop junction pieces. Customised pieces can be made to suit and in such cases, drawings must be provided giving exact dimensions and jointing details.
Where shown on the drawings waterstops shall be Sure-Shield® TPER Chemical Resistant Waterstop (state profile number required) as supplied by CJSA. Provide factory made waterstop fabrications for all changes of direction, intersections and transitions, leaving only straight butt joined splices for on-site fabrication.
HEALTH AND SAFETY INFORMATION
Joining of Sure-Shield® TPER Waterstops is performed by heat welding which results in the discharge of hydrogen chloride mist and vapour. In confined spaces or in still air conditions, the use of a ventilation fan or suitable respirator should be used, and the advice and approval of the Site Safety Supervisor is essential. For further information or advice on health and safety precautions, safe handling, storage and correct disposal of products, please refer to the most recent product Safety Data Sheet (SDS), which is available upon request.
