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.

AT System waterstops have been specially developed for water excluding and retaining structures such as basements, reservoirs, sewage treatment works, etc. The AT System is an important advance in concrete joint protection which combines Active Technology with the conventional mechanical properties of PVC waterstops.
- Increased security – combines advantages of PVC waterstop with active hydrophilic elements to provide maximum resistance to water pressure
- Continuously active sealing – hydrophilic elements swell in contact with water to plug voids formed by normal concrete shrinkage
- Prevents water tracking – location of active element is designed to prevent lateral migration of water along waterstop bulb
PVC EDGETIE™ is an internally cast passive waterstop system manufactured in a range of sizes for sealing joints in concrete structures subject to water pressure.
- Proven profile - solid circular end bulbs promote better concrete compaction and simplifies site jointing
- Flexible - will accommodate movement during construction and service life
- Valve action - created by concrete shrinkage around end bulbs
SERVISEAL® is a passive external PVC waterstop system manufactured in a range of sizes for protecting joints in concrete basements and sub-structures.
- Proven design
- Flexible
- External seal
- Pliable
SWELLSEAL® Mastic is a one-component, polyurethane-based, solvent free, hydroswelling mastic, supplied in cartridges and aluminium sausages, for the sealing of construction joints and around pipe penetrations. SWELLSEAL® Mastic cures and swells in the presence of moisture.
- Solvent free
- Flexible system
- Easy application with standard caulking gun
- Durable
- Sealing rough and smooth construction joints of in-situ cast concrete
- Sealing joints between pre-cast segments
- Sealing around steel H-beams
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.
