Swelling Waterstop Headquarters

Hydro-Flex is the BoMetals hydrophilic waterstop which provides a lasting compression seal. It meets standards set for cold joints in a number of situations. For areas requiring environmental protection, TPER waterstop is the rule. For non-expansive seals, Synko-Flex should be your choice because of its wide applications.

Waterstop Specs

When using waterstops for joints, it is expected you know your business. Waterstops must be placed properly and used in the appropriate site. Every construction site issues waterstop specs at the designers' discrimination. Swelling waterstops and TPER waterstop protection are made in accordance with federal guidelines and industry standards. TPER, in particular, is so important for consumer safety as well as having commercial benefits, that our products not only meet, but exceed industry standards.

TPER Waterstop and Safety

This waterstop is primarily for containment of EPA sensitive materials. BoMetals make the installation easier with factory-made fittings for the required changes in direction. Without the specially designed accessories, failures may occur given the difficulty in splices otherwise. We make it an easy installation and your workers only need perform butt welds with minimum equipment. Contact us today to find out what concrete form accessories are right for you.

TPER remains flexible in cold temperatures, and this may be critical depending on your climate. The difference between this and other swelling waterstop is its ability to withstand chemicals that can effect the composition of waterstop's structure. TPER will last indefinitely under pressure and continuous exposure to water and toxins.
