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.

Earth Shield® Type 20 & Type 23 Hydrophilic Butyl Rubber Waterstops are designed to swell when exposed to water, yet maintain a solid structural integrity that will not deteriorate due to uncontrolled expansion, unlike many of the traditional, clay-based waterstops currently on the market. This swelling ability prevents the passage of water through concrete construction joints. Type 20 & 23 waterstops are fast, easy, and economical to install. Simply apply Earth Shield® Primer to the existing concrete, firmly press the waterstop to the primed surface, and place your second pour of concrete. No splitting of forms or difficult field welding is necessary to achieve a watertight seal.

Earth Shield® 125CR Chemical Resistant Strip Waterstop is designed to prevent the passage of aqueous hydrocarbons through non-moving concrete joints in environmental engineered concrete structures. The product aggressively bonds to most substrates and is unaffected by rain or wet conditions during installation.

The ST-10® was designed and patented by J P Specialties as the perfect solution for producing high-tensile strength, leakproof welds on thermoplastic waterstops such as PVC, HDPE, LDPE, TPER, and TPV. New quality assurance standards in today’s waterstop specifications mandate tensile testing across field welded joints, usually requiring tensile strength 80% or better of the parent material. Waterstops welded with the ST-10® assure the Contractor that their workmanship will yield results conducive to these rigorous requirements. The ST-10® is also an extreme labor saver, taking a two-man job — welding waterstop — and taking it down to just one man.

• Easy to use
• Aligns the waterstop
• Portable, lightweight
• Weather resistant
• Minimizes fumes (maximizes safety)
• High tensile welds
• Welds under pressure, eliminating air bubbles
