Thermoplastic Waterstop for Water, Chemical and Ozone Resistance

Ribbed Centerbulb Waterstop

Ribbed centerbulb is the most versatile type of waterstop available. The centerbulb accommodates lateral, transverse, and shear movement. Ribbed centerbulb waterstop can be used in expansion, construction, and control joints. Click here for more info and CAD details...

Retrofit Waterstop Systems

Retrofit waterstop is designed to provide a fluid-tight seal between existing and new concrete construction. Click here for more info and CAD details...

Dumbbell and Dumbbell Centerbulb Waterstop

Usually used in below grade applications, where limited movement is expected. Click here for more info and CAD details...

Base Seal Waterstop

Ideal for flat pavement jobs such as runways, large containment slabs, etc. Click here for more info and CAD details...

Integrated Cap Systems Waterstop

Designed to replace post-applied joint sealant, and provide a fluid-tight internal seal like a traditional waterstop with a one-step, integrated unit. Click here for more info and CAD details...

Special Waterstop Shapes

Additional shapes are available for special applications. Currently, Earth Shield manufactures a tear web waterstop, designed for large joint movements such as tank foundations. Click here for more info and CAD details...

Thermoplastic Vulcanizate (TPV / TPER) Waterstop Basic Use

Earth Shield Thermoplastic Vulcanizate Waterstop 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, 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 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.

Different varieties and grades of thermoplastic elastomers (TPE) are commercially available. On the low-end there is thermoplastic polyolefin (TPO), which has a rubber phase that is not cross-linked. On the high-end there is thermoplastic vulcanizate (TPV)... Earth Shield has chosen a fully cross-linked TPV as our standard elastomer compound, which provides superior mechanical properties, retention, and chemical resistance. In fact, when compared side-by-side, no competitive product is even close to achieving the physical properties of Earth Shield.

Installation

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 #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.

More detailed installation instructions can be found in our Standard 3-part Specifications.
