Thermoplastic Vulcanizate (TPV / TPER) Waterstop Basic Use, Physical Properties, and Installation
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, ozone, and aggressive industrial fluids. Also, unlike PVC waterstop, Earth Shield can withstand prolonged exposure to high and low temperatures (-164°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.
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.
Ribbed Centerbulb Waterstop JP436, JP636, JP936
Ribbed centerbulb is the most versatile type of waterstop available. The centerbulb accommodates lateral, transverse, and shear movement. Ribbed centerbulb can be used in expansion, construction, and control joints. Ribbed centerbulb waterstops provide superior anchoring abilities and a long fluid-flow path because of the multiple ribs on the exterior flanges. Under stress, the multiple ribs will distort less than a dumbbell type waterstop. This is because the stress is first applied to the inward-most anchoring rib, and decreases to the subsequent ribs.
The centerbulb allows for joint movement beyond the ultimate elongation of the material (530%), without causing distortion to anchoring ribs. All of our ribbed centerbulb waterstops are manufactured with a 9/16” outer diameter centerbulb, which is the largest in the industry. This centerbulb, coupled with the outstanding mechanical properties of our proprietary TPV elastomer (ultimate elongation, tensile strength, etc.), provides for unsurpassed joint movement and sealing abilities. Like all our thermoplastic vulcanizate waterstops, Earth Shield ribbed centerbulb waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
Retrofit Waterstop Systems JP320L, JP325T, JP336L, JP450T, JP500, JP540L, JP621L, JPEB375R
Retrofit waterstop is designed to provide a fluid-tight seal between existing and new concrete construction, without resorting to the labor-intensive and structurally destructive saw-cut-and-grout method. It is ideal for constructing a new containment curb or wall to an existing slab, or joining a new slab to an existing wall. Special profile fabrications are available for columns and pipe penetrations.
All of our retrofit waterstops are sold as a complete system, and include all the necessary stainless steel bars and bolts. We also offer a high-quality chemical resistant novolac epoxy — VEN 1000. Earth Shield retrofit waterstops are manufactured with our proprietary thermoplastic vulcanizate compound, which provides for unsurpassed chemical resistance. Like all our thermoplastic vulcanizate waterstops, Earth Shield retrofit waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
Pipe and Column Fitting Waterstop Seal
Earth Shield has solved a long-standing problem for engineered concrete structures with circular protrusions, such as columns, pipes, piers, and pilasters. The problem: how to permanently seal the concrete joint when cast-in-place concrete is formed against an existing circular member. The solution: Earth Shield Column & Pipe Fitting (part no. JP320LC1.XX* [*XX is the diameter in inches]) manufactured with a flexible, chemical-resistant polymer and stainless steel anchoring hardware. A single laborer on the job site can quickly install the column fitting and its associated hardware. Simply apply an epoxy gel bed to the existing surface; place the polymer ring into the epoxy gel bed; heat weld the single opening on the polymer ring using a waterstop splicing iron; and finally, complete the system with the stainless steel closure ring.
The Earth Shield system functions as an internal dam, centrally located within the cast concrete, to stop aggressive chemicals, solvents and hot petroleum oils from penetrating the joint. By preventing the passage of hazardous liquids the Earth Shield Column & Pipe Fitting provides facility owners, engineers, and contractors with the necessary EPA-mandated containment compliance (EPA Title 40 CFR 265.193). Of course, the system prevents the passage of water as well. The mechanical properties of the polymer, plus the tear-web design of the JP320L profile, enable the column fitting to function equally well in expansion (isolation) joints and construction joints.
Integrated Cap Systems JPEB350, JPEB375, JPEB375R, JP158, JP1225
Integrated expansion board cap waterstop systems are designed to replace post-applied joint sealant, and provide a fluid-tight internal seal like a traditional waterstop with a one-step, integrated unit. Earth Shield expansion board cap waterstop is installed on top of conventional expansion board filler or Earth Shield’s own chemical resistant, plastic expansion board. The expansion board acts as the form; therefore, no form splitting is necessary. This greatly accelerates the project schedule and provides a long lasting, attractive finished concrete joint. Earth Shield screed key cap slides over the top of metal screed key, eliminating the need for sealant. Like all our thermoplastic vulcanizate waterstops, Earth Shield integrated cap system waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.

Special Shapes Waterstop JP678, JP978, JP540L, JP621L, JP1225
Earth Shield tear web waterstops are designed for large joint movements such as tank foundations. Tear web is suitable for expansion joints. For construction and contraction (control) joints, ribbed centerbulb should be used instead. We also manufacture a retrofit product specifically designed to accommodate large shear movements, such as tank ring foundations subjected to settlement. The JP621L Retrofit Waterstop System is chemically and mechanically adhered to the existing concrete using one of our chemical resistant, novolac epoxies (VEN500 or VEN1000), stainless steel batten bar, and stainless steel anchor bolts. New for 2010, Earth Shield part number JP540L is designed to act as an external, post-installed, retrofit waterstop seal, ideal for sealing between walls and slabs. Like all our thermoplastic vulcanizate waterstops, Earth Shield tear web and large movement retrofit waterstops can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
Base Seal Waterstop JP211, JP621L
Base seal waterstop is ideal for flat pavement jobs such as runways, large containment slabs, etc. Base seal waterstop is by far the easiest waterstop to install... Simply lay the waterstop directly on the compacted subgrade, place and finish concrete, and create control joint using saw cut or other method. The base seal provides a permanent, life-of-structure seal at the bottom of the joint. Base seal is suitable for construction, contraction (control), and expansion joints. Base seal should not be used on jobs that make interior wall transitions as the part is non-symmetrical and therefore cannot function correctly. For large hydrostatic head pressures (>50 foot) ribbed centerbulb should be used instead. Like all our thermoplastic vulcanizate waterstops, Earth Shield baseseal waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
Dumbbell Waterstop JP647, JP648, JP948, JP949, JP1149
Dumbbell waterstop is usually used in below grade applications, where limited movement is expected. Dumbbell waterstop can be installed in construction and contraction (control) joints; whereas, dumbbell centerbulb can be installed in construction, control, and expansion joints. The large centerbulb (1-1/2” outer diameter) on the JP949 (and JP1149) waterstop profile, coupled with the outstanding mechanical properties of our thermoplastic vulcanizate and large endbulb anchors, enable the product to withstand large-scale joint movement (seismic, settlement, etc.). JP648, JP948, JP949 and JP1149 are all 3/8” thick... The largest and thickest profiles available in the industry! Like all our thermoplastic vulcanizate waterstops, Earth Shield dumbbell waterstop can be heat-welded using a standard waterstop splicing iron. This allows for easy field fabrications, and allows the waterstop to function as a continuous, homogeneous, fluid-tight diaphragm. Waterstop change of directions can be purchased along with straight roll stock, and custom, fit-to-print waterstop modules are produced to order. Prefabricated ells, tees, tank pads, column fittings, and many others are in stock and ready to ship.
