Hydrotite Waterstop


Hydrotite is a state-of-the-art hydrophilic waterstop with unmatched durability and water-sealing capacity. Comprised of Non-Bentonite, modified chloroprene rubber, Hydrotite expands up to eight times its original volume when exposed to water. This expansion creates an effective compression seal within joints of limited movement. Recognized worldwide, Hydrotite has a proven track record as a high-quality and cost-effective solution to your water containment needs.


Typical structures utilizing Hydrotite

• Water and wastewater treatment facilities
• Primary and secondary containment structures
• Tunnels and culverts
• Dams, locks, canals, water reservoirs, and aqueducts
• Pipe penetrations
• Swimming Pools
• Storage tanks
• Retaining Walls
• Foundations
• Slabs on grade

1. For best results apply Hydortite to smooth, even surfaces to ensure good bonding.
2. Provide 2” minimum concrete cover
3. Hydrotite can be installed on the plain surface of concrete or in a formed keyway.
4. Hydrotite should be spliced by cutting ends square with a sharp knife or shears. Bond the prepared ends together with a cyanoacrylate (super glue) adhesive.
5. Remove all dust, oil, etc from the concrete surface prior to adhering Hydrotite.
6. Hydrotite is available with an adhesive back for adhering to the concrete surface. Bonding of Hydrotite profiles can be accomplished using a contact adhesive compatible with chloroprene rubber.
7. Concrete nails, in conjunction with adhesives, are recommended for vertical or overhead applications.
