Flexible 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.
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.

WATER IS OUR MOST VALUABLE COMMODITY. IT IS IMPORTANT TO PROTECT IT, EITHER FROM LOSS OR POLLUTION. PROPERLY INSTALLED WATERSTOP ACHIEVES BOTH GOALS.

THE CHEMICAL RESISTANCE OF THE WATERSTOP MATERIAL, EXPOSURE, TEMPERATURE, CHEMICAL CONCENTRATION OF THE CONTAINED MATERIAL, AND ANY REQUIREMENTS FOR JOINT MOVEMENT SHOULD BE CONSIDERED WHEN SELECTING THE WATERSTOP MATERIAL.

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.
