TX PVC Waterstop

CJSA TX PVC Waterstop is a specially designed profile for use in construction or expansion/isolation joints in concrete where you require a waterstop in the joint between an existing structure to a new structure.

  • Ability to waterstop the joint where traditional PVC waterstop profiles or other waterstop systems cannot be placed.
  • Able to accommodate large movements in expansion/isolation joints due to its innovative design.
  • Able to accommodate longitudinal, lateral and differential movements in expansion/isolation joints.
  • A high performance material produced from virgin PVC compound (refer to material specification) giving long-term integrity and durability over time. No scrap or recycled PVC’s are used.
  • Water stops the joint and allows it to expand and contract freely from movements caused by thermal fluctuations and serviceability loads from within the structure.

All types of construction or expansion/isolation joints in concrete where an existing structure and new structure meet and require a waterstop.

Note: The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

Note: Refer to CJSA’s in house Certificate of Analysis (COA) dated 13/12/2018 for test results pertaining to the above. Internal COA’s are conducted on every batch of raw material that is used in the production of TX 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.

Note: TX PVC Waterstop is available in 3 metre lengths

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 TX 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. Refer to our PVC Waterstop Site Joining Guidelines for further information on the above.

  1. TX-100 PVC Waterstop should only be installed into an expansion/isolation joint with a maximum width of 30mm and with a maximum movement (longitudinally and vertically) of 50mm. If a wider joint or wider range of movement is required, please consult CJSA.
  2. TX-150 PVC Waterstop should only be installed into an expansion/isolation joint with a maximum width of 50mm and with a maximum movement (longitudinally and vertically) of 50mm. If a wider joint or wider range of movement is required, please consult CJSA.
  3. TX PVC Waterstop must be installed by skilled installers and must be in accordance with CJSA’s recommended installation procedures (refer to our “Installation Method Guideline”) or your engineers design.
  4. TX PVC Waterstop and its ancillary items for installation must be supplied from CJSA. (refer to our “Installation Method Guidelines – Ancillary Items List”).

Hydrostatic head pressure resistance testing has not been directly undertaken on our TX PVC Waterstop profiles.

Based on parameters documented in the Corps of Engineers document, ‘Waterstops and other Preformed Joint Materials for Civil Works Structures EM1110-2-2101, (30th September 1995)’ and installed in accordance with the installation instruction, the profile TX-150 can withstand up to 20 metre of water pressure.

For the extension legs of the TX profiles, we have two profile lengths at 100mm (TX-100) and 150mm (TX-150) and these leg lengths of the waterstop, once cast into the new concrete section can withstand the following hydrostatic head pressure resistance:
• TX-100 @ 12 metres (1.2 Bar)
• TX-150 @ 20 metres (2.0 Bar)

  1. Installation of TX PVC Waterstop must be in accordance with our recommended installation procedures (refer to our “Installation Method Guideline”).
  2. TX PVC Waterstop and its ancillary items for installation must be supplied from CJSA (refer to our “Installation Method Guideline – Ancillary Items List”).
  3. The concrete must be fully vibrated around the TX PVC Waterstop to help achieve ultimate sealing capabilities and full integration of the waterstop into the structure.
  4. Joining of TX PVC Waterstop must be performed by heat welding with special equipment provided by CJSA (refer to our job site joining/welding method guideline).
  5. Factory fabricated intersections must be used to connect traditional types of PVC waterstop to TX PVC Waterstop. Special intersections will be required to join the waterstops that are being used in the construction or expansion joints that run perpendicular into the construction, expansion/isolation joint where the TX PVC Waterstop is to be placed. Contact CJSA for further details.
  6. All joints of the concrete structure that run perpendicular into the construction or expansion/ isolation joint where the TX PVC Waterstop is to be used, must have waterstops in them. If they are construction joints, then traditional construction joint PVC waterstops or a Hydrophilic Waterstop can be used (refer to our recommended installation procedures). If traditional PVC waterstops are to be used, then refer to item 5 above, or your design engineer’s recommendations.

Waterstop shall be TX PVC Waterstop (state profile type) as supplied by CJSA with dimensions, shape and material properties as illustrated/mentioned in their brochure. All installation and joining procedures must be according to their recommendations and requirements, and also approved by the project’s design engineer.

Joining of TX 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.
