TPV Waterstop

Earth Shield® Thermoplastic Vulcanizate Waterstop (TPV) (aka TPE-R) is used as a fluid-tight diaphragm, embedded in concrete, across and along the joint, for primary and secondary containment structures. Earth Shield® Chemical Resistant Waterstops are resistant to a wide range of oils, solvents, and aggressive chemicals. Alcohol, ketones, glycols, esters, and aqueous solutions of acids, salts, and bases have little effect on Earth Shield® Thermoplastic Vulcanizate Waterstop.

Unlike polyvinyl chloride (PVC) waterstop, Earth Shield® waterstop contains no plasticizer, stabilizer, or filler to leech out when exposed to chemicals, fuels, ozone, and aggressive industrial fluids. Also, unlike PVC waterstop, Earth Shield® can withstand prolonged exposure to high and low temperatures (-78°F to 275°F long term) without detrimental effect. Earth Shield® TPV Waterstop is NSF Standard 61 certified for use in drinking water and is made of a recyclable polymer, so it’s good for your health and the environment.

The superior chemical resistance of Earth Shield® Thermoplastic Vulcanizate Waterstop is enhanced by the use of a ribbed centerbulb configuration, which is available in a 4, 6, and 9-inch width. This provides for greater mechanical bonding with the concrete and a barrier against migration of liquid flow around the waterstop. The ribbed centerbulb style also allows for joint movement and may be used in above or below grade applications. Additional shapes are available for retrofit, extreme expansion, stainless steel and base seal applications.

Install Earth Shield® TPV Waterstop in all concrete joints. Waterstop should be centered in, and run the extent of the joint. All changes of directions should be prefabricated (see Shop Made Fittings), leaving only butt-welding for the field. If installing in an expansion joint, keep center bulb unembedded to allow it to accommodate movement as designed. Use optional factory installed brass eyelets (or #3 hog rings) and tie wire to secure waterstop to reinforcing steel to avoid displacement during the concrete pour. Splice straight lengths of waterstop and Shop Made Fittings to straight lengths, with an ST-10® In-Line Waterstop Splicer with the iron temperature set to 410°F to 430°F.

Qualified technical assistance is available during any phase of your construction project. 

Standard 3-part Specifications are available at our website in Microsoft Word and Adobe PDF format, and upon request in printed and a variety of computer word processor formats. Call our Technical Sales Staff for additional help with your specification.

Concrete is everywhere: Buildings, fountains, parking decks, locks and dams, roads and bridges, and myriad other constructions. Because of its long lifespan, high workability, and near-worldwide availability, concrete is the preferred building material for large structures, especially those subject to hydraulic pressure. Not all concrete structures require protection from the ingress of water or other fluids, but those that do require a properly installed waterstop in and along their concrete joints. The concrete joint is the most likely point of leakage and waterstops are uniquely designed to prevent this. This book’s sole purpose is to educate the reader on all facets of waterstop.
