XB PVC WATERSTOP
HIGH PERFORMANCE SPECIFICATION (HPS) GRADE
CORK JOINTING SYSTEMS XB PVC Waterstop is a specially designed profile for use in expansion/isolation joints in concrete where traditional PVC waterstop profiles cannot be placed due to the interference of reinforcement bars.
- Ability to waterstop the joint where traditional PVC waterstop profiles cannot be placed due to their inappropriate design and width.
- 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 load from within the structure.
- Easy to install (refer to our recommended installation procedures).
AREAS OF APPLICATION
- Expansion/isolation joints in concrete where reinforcement does not allow the use of traditional, wider type, PVC waterstop profiles.
- Double beam expansion joints.
- Podium slab to building expansion/isolation joints.
- Slab to column expansion joints.
- Slabs & suspended slabs with double beams & columns.
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 Cork Jointing Systems’s in house Certificate of Analysis (COA) dated 13/09/2017 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 XB 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: XB PVC Waterstop is available in a 10 metre roll length.
- Installation of XB PVC Waterstop must be in accordance with our recommended installation procedures. (refer to our “installation method guideline”) or refer to your designer engineer’s recommendations.
- The concrete must be fully vibrated around the XB PVC Waterstop to help achieve ultimate sealing capabilities and full integration of the waterstop into the structure.
- Joining of XB PVC Waterstop must be performed by heat welding with special equipment provided by the supplier. (refer to our “on site joining guidelines”).
- Factory fabricated intersections must be used to connect traditional types of PVC waterstops to XB PVC Waterstop.
- Special intersections will be required to join the waterstops that are being used in the construction or
expansion joints that run perpendicular to the expansion/isolation joint where the XB PVC Waterstop is to be placed. Contact us for further details or refer to your designer engineer’s recommendations.
- All the joints of the concrete structure that run perpendicular into the expansion/isolation joint where the XB PVC Waterstop is being used must have waterstops in them. If they are construction joints, then traditional PVC watestops or our Superswell® 47B hydrophilic waterstop can be used (refer to our recommended installation procedures). If traditional PVC Waterstops are to be used, then refer to No. 4 above or refer to your designer engineer’s recommendations.
A. Place formwork into position for beam and slab. Formwork for XB PVC Waterstop application at expansion joint must be split and secured fully. 1st pour of concrete is now ready to be placed.
Note: XB PVC Waterstop must be secured firmly into position and 1st pour of concrete must be fully vibrated around the product.
B. Once 1st pour is completed, remove formwork from face of slab and beam and fix expansion joint fillerboard into position. 2nd pour of concrete is now ready to be placed.
C. Place 2nd pour of concrete into position and against expansion joint fillerboard. Vibrate concrete fully around the XB PVC Waterstop
- XB-75 PVC Waterstop should only be installed into an expansion/isolation joint with a width of 10mm-25mm.
- XB-100 PVC Waterstop should only be installed into an expansion/isolation joint with a width of 30mm-50mm.
- Each leg length section of the XB PVC Waterstop that is to be embedded into the concrete, must penetrate by a minimum of 25 mm into each side of the joint. This means that the reinforcement cover must be at a minimum of 30 mm to allow for the waterstop leg to fit into the concrete, or refer to your designer engineer’s recommendations.
Note: Proposal, specification, design and end use of this product must be fully endorsed and approved by the Design Engineer.
CORK JOINTING SYSTEMS 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 XB PVC Waterstop requires its own welding jig to suit the particular shape). On-site joining is a simple exercise using
CORK JOINTING SYSTEMS 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
Waterstop shall be XB PVC Waterstop (state profile type) as supplied by CORK JOINTING SYSTEMS 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.
HEALTH AND SAFETY INFORMATION
Joining of XB PVC Waterstop 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.
