Waterstops
Flexible waterproofing for concrete joints
The way to a better waterstop.
Waterstops represent a critical component of any waterproofing system. Due to shrinkage and settling, the surfaces of a concrete cold joint will never perfectly conform to one another. Without a flexible barrier that can accommodate the imperfections of concrete surfaces, water will have the opportunity to creep in through the seam.

- Remedial 'breaking out' of concrete
Adcor® 500T is a unique product that has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.
- Controlled volumetric expansion – reduces risk of concrete spalling.
- Conformable – can be installed onto a variety of irregular substrates.
- Retains cohesive strength at both original and expanded volume.
- No need for protective steel mesh.
- Resists at least 6 bar (87 psi) hydrostatic pressure.
- Volumetric expansion over 140% in 8% salted water.
- Simple overlap jointing on site.
- Reproducible swell after wet – dry cycling.
- Unaffected by freeze/thaw cycling.
- Horizontal and vertical construction joints in concrete structures
- Casting new concrete against existing
- Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant pile walls.
- Joints between floor slabs and pile caps
- Pipe penetrations through floors and walls
SWELLSEAL® Mastic WA is a one-component, grey, polyurethane-based, elastic, hydro-swelling mastic, supplied in aluminium sausages, for the sealing of expansion joints and around pipe penetrations.
- Due to its special formulation, Swellseal® Mastic WA can be applied onto wet surfaces or in underwater applications.
- Suitable for fresh or salt water applications.
- Solvent free.
SWELLSEAL® Mastic WA is preferably applied onto a dust-free concrete surface. The surface can be rough or smooth, moist or dry. When applying SWELLSEAL® Mastic WA in underwater or very wet applications, be certain to cast the concrete within 6 hours to prevent premature swelling.
WATER-BAR™ XR-2010 is a preformed, 20mm x 10mm rectangular section, modified rubber waterstop. On contact with water, the hydrophilic rubber swells, increasing in volume by over 300% in 9 to 12 days.
It stops water passage by the compressive force generated by the rubber’s moisture induced expansion and its natural resilience. Small movements in the joint are taken up by the re-swellable seal of the product.
- Contains no bentonite materials – provides long term performance
- Simple installation – roll out and mechanically fix at maximum 300mm centres
- Supplied as light weight 10 meter rolls
- No welding or complex detailing required

The GCP advantage
Our waterstops are specifically designed to resist job-site conditions while outperforming other solutions. These waterstops offer innovative technology options to meet a wide variety of project needs. This includes tricky or problematic installations where technical finesse is required. No matter the project, we have a waterstop that’s ideal for the job.
Waterstop Solutions
Our solutions incorporate advanced materials that prevent water infiltration in ways that other waterstops can't. Novel engineering technologies result in waterstops that conform more securely to concrete surfaces, last longer and provide more flexibility to contractors. For more information about these and other waterstop solutions, contact GCP today.
ADCOR®
An advanced hydrophilic waterstop that's compatible with all of our industry-leading waterproofing membranes. ADCOR® is engineered to expand when it comes in contact with water. The material seals against concrete faces when encapsulated and resists water infiltration through a cold joint.
INJECTO® Tube Groutable Hose Waterstop System
An injectable waterstop system that provides a passageway for a variety of chemical grouts. The system is designed to be laid down before concrete is poured, but not injected until well after it has cured. This allows the cracks created by shrinkage during the curing process to fully open. The resulting interfaces and voids can then be permanently sealed.
TRIOject® Multiple Grout Injection Hose
Comprised of a three-channel PVC-hose, TRIOject® allows for multiple grout injections in a more durable enclosure. Each of the three grout channels contains micro holes that prevent water from getting in, but allow grout to escape. The system is protected by a steel mesh on top, as well as a foam pad on the bottom that conforms to the concrete surface. Crucially, the three-channel TRIOject® design lets builders inject the same cold joint multiple times—a best-in-class solution for a critical or problematic application.
