HYDRO-STOP® PVC WATERSTOP

STANDARD PROFILES
STANDARD PERFORMANCE SPECIFICATION (SPS) GRADE

PRODUCT DESCRIPTION

CJSA Hydro-Stop® PVC Waterstops lead the way in high technology
waterstops and comply with international standards.Hydro-Stop® PVC Waterstops are extruded from specially compounded PVC in accordance with BS2571 and they are designed for use in water retaining and water excluding structures where a positive seal is required for poured in-situ concrete expansion, construction and contraction joints.

Hydro-Stop® PVC Waterstops are designed for use in many types of applications and structures, and are available in a number of different size profiles to suit a project’s requirement.

Hydro-Stop® PVC Waterstops are available in rolls with separate intersections supplied to simplify and minimise on-site fabrication. The waterstop is heat weldable and allows for fast and easy on-site welding/joining.

The efficiency of any waterstop is very dependent on good workmanship, installation, and on full compaction of the surrounding concrete around the waterstop during concrete placement. Optimum performance will beachieved if the waterstop is installed by keeping these important factors in mind.

PHYSICAL PROPERTIES

Note: Refer to CJSA’s in house Certificate of Analysis (COA) dated 15/08/2017 for test results pertaining to the above. A COA is conducted on every batch of raw material that is used in the production of Hydro-Stop® PVC waterstops. Independent laboratory test results are also available upon request. Project specific material properties can be custom compounded to suit. Material properties can vary between batches.

PROFILE DRAWINGS

Note: Full dimension drawings 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.

SITE JOINING

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 Hydro-Stop® PVC 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 PVC fuse. When ordering Welding Equipment, please advise profile number of the waterstop required.

FACTORY MADE INTERSECTIONS

A wide range of standardised prefabricated intersection pieces are available allowing easy site welding of butt joints to Hydro-Stop® PVC Waterstop junction pieces. Customised pieces can be made to suit. In such cases, drawings must be provided giving exact dimensions and jointing details.

WRITTEN SPECIFICATION

Where shown on the drawings waterstops shall be Hydro-Stop® PVC 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 PVC 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.
