TPV Waterstop — Earth Shield® Thermoplastic Vulcanizate (TPV) Waterstops (the vulcanized version of a Thermoplastic Elastomeric Rubber [TPER]) are free from harmful chemicals like plasticizers and heavy metals commonly found in other polymers, making them safer for both the environment and human health. TPV is also lighter than other rubbers, helping reduce transportation emissions and overall environmental impact. As a thermoplastic, TPV can be repeatedly melted and reshaped without losing its essential properties, making it a sustainable material easily recyclable and reusable in new products. TPV also has the most extended lifespan in structural applications, which minimizes the need for replacements and reduces material consumption over time. TPV's eco-friendly nature, longevity, and recyclability contribute to long-term sustainability. Earth Shield+® TPV Waterstop is made from renewed materials and is available upon request.

PVC637 in Forms

PVC Waterstop — Recycling Polyvinyl Chloride (PVC) reduces the demand for raw materials like fossil fuels used in its production and minimizes the amount of waste sent to landfills. However, due to their inherent toxicity, PVC's use of plasticizers (phthalates) and fillers presents an environmental challenge. Earth Shield® PVC Waterstop is less toxic (non-hazardous phthalates) and NSF 61 and California Prop 65 certified. Earth Shield+® PVC Waterstop is made from renewed materials, is still toxin-reduced, and is available upon request.

Stainless Steel Waterstop Fabrications

SS Waterstop — Earth Shield® Stainless Steel Waterstop is 100% recyclable and can be reused to create new products without losing their original properties, reducing the need for raw material extraction and minimizing environmental impact. Its durability and corrosion resistance ensure a long, sustainable lifespan with minimal maintenance, lowering the demand for replacements and conserving resources over time. Additionally, stainless steel is non-toxic and does not leach harmful chemicals into the environment. Since it can be recycled indefinitely, it supports sustainability by reducing the demand for virgin materials such as iron, nickel, and chromium, conserving natural resources, and lessening the environmental impacts of mining.

MCR Waterstop

MCR Waterstop — Earth Shield® Modified Chloroprene Rubber (MCR) is highly durable and has a long lifespan, reducing resource consumption over time. Our formulation is designed to minimize or eliminate the use of harmful substances, such as bisphenol A (BPA) or other modifiers, making it a more environmentally friendly option compared to other elastomeric products that rely heavily on such additives. With ongoing advancements in production and recycling, its environmental impact can be further reduced, contributing to long-term sustainability.

Sustainability is an increasingly important consideration in construction materials. Earth Shield® waterstops from J P Specialties, Inc. are available in multiple material types, each offering different levels of recyclability and environmental impact. Understanding these differences helps engineers and specifiers select the most appropriate solution for both performance and sustainability goals.

Material Comparison
TPV (Thermoplastic Vulcanizate) Waterstops
  • Recyclability: High
  • TPV is a thermoplastic elastomer that can be melted and reprocessed multiple times without significant degradation.
  • Supports circular use of materials and reduces manufacturing waste.
  • Long service life further enhances sustainability.
Best Use: Projects prioritizing recyclability and long-term environmental performance.

PVC (Polyvinyl Chloride) Waterstops
  • Recyclability: Moderate
  • PVC can be recycled; however, additives such as plasticizers can complicate the recycling process.
  • Widely used and cost-effective, but less environmentally favorable than TPV.
Best Use: General applications where cost and performance are primary drivers, with some benefit from recyclability.

Stainless Steel Waterstops
  • Recyclability: Excellent
  • Stainless steel is fully recyclable with no loss of material properties.
  • Can be reused indefinitely and has a very high recovery rate in industrial recycling streams.
Best Use: Projects requiring maximum durability and the highest level of recyclability.

MCR (Modified Chloroprene Rubber) Waterstops
  • Recyclability: Limited
  • Designed for durability and resistance to harsh environments.
  • Recycling options exist but are less established than thermoplastics.
Best Use: Chemical or industrial environments where performance takes precedence over recyclability.
Additional Sustainability Considerations
  • Select Earth Shield® products incorporate recycled or renewed materials.
  • Manufacturer-supported jobsite recycling and material recovery programs may be available.
  • Longer service life reduces replacement frequency and lifecycle waste.
Key Takeaways
  • Most recyclable options: TPV and stainless steel
  • Moderately recyclable: PVC
  • Durability-focused (less recyclable): MCR
Selecting the appropriate waterstop material can contribute to LEED goals, waste reduction strategies, and overall project sustainability.

Specifier Tip
When sustainability is a project priority, specify TPV or stainless steel waterstops and confirm the availability of recycling programs with the manufacturer early in the project lifecycle.
For additional technical guidance, consult the full Earth Shield® Waterstop Technical Library or contact J P Specialties, Inc. for project-specific recommendations.
WATER IS OUR MOST VALUABLE COMMODITY. IT IS IMPORTANT TO PROTECT IT, EITHER FROM LOSS OR POLLUTION. PROPERLY INSTALLED WATERSTOP ACHIEVES BOTH GOALS.
