Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-quality construction waterproofing materials since 1998. Our 0.8mm Thick Copper Waterstop with 200mm width and 20m length is specifically designed to provide reliable sealing for concrete joints in demanding infrastructure projects. Crafted from pure copper, this waterstop offers exceptional corrosion resistance and long-term durability, making it an ideal choice for dams, tunnels, water treatment plants, and basements. With annual export value exceeding US$5 million, we serve clients across North America, Europe, Southeast Asia, and beyond, ensuring consistent quality and competitive pricing.
Copper waterstops function by creating a watertight barrier within concrete joints, preventing water ingress and structural damage. Our 0.8mm thickness strikes the perfect balance between flexibility for easy installation and robustness for enduring performance. The 200mm width provides ample coverage for standard joint configurations, while the 20m length minimizes waste and reduces installation time. Below, we detail the key features and technical specifications of this product.
Key Features & Benefits
- High-Purity Copper: Made from 99.9% pure copper, ensuring excellent resistance to chemical attack and corrosion even in aggressive soil or water conditions.
- Optimal Thickness: 0.8mm thickness provides sufficient rigidity for maintaining shape during concrete pouring while remaining flexible enough to conform to irregular joint movements.
- Convenient Dimensions: 200mm width and 20m length per roll reduce the number of joints needed, simplifying installation and lowering labor costs.
- Long Service Life: Copper naturally develops a protective patina, extending the lifespan of the waterstop beyond 50 years in most environments.
- Easy Handling: Supplied in coiled rolls, easy to cut and shape on-site, with no special tools required.
- Versatile Application: Suitable for both vertical and horizontal joints, including expansion joints, contraction joints, and construction joints.

Our copper waterstop is manufactured under strict quality control processes, ensuring consistent thickness and width throughout each roll. The material is annealed to achieve the desired ductility, making it easier to bend and shape around rebar or formwork. For projects requiring non-standard dimensions, we offer customization options including different widths (150mm, 250mm, 300mm) and thicknesses (0.6mm, 1.0mm, 1.2mm) upon request.
Installation & Handling Tips
- Uncoil the waterstop and allow it to straighten before installation.
- Secure the waterstop at the center of the joint using tie wires or clips, ensuring it is not displaced during concrete pouring.
- Overlap adjacent sections by at least 50mm and solder or weld joints for continuous watertightness.
- Keep the copper surface clean and free of oil or grease to ensure proper bonding with concrete.
- For cold weather, pre-warm the material slightly to avoid cracking during bending.
Compared to PVC or rubber waterstops, copper offers superior resistance to ultraviolet radiation, chemicals, and biological attack. It is also non-aging and maintains its mechanical properties over decades, making it a cost-effective solution for critical infrastructure with service lives exceeding 50 years.
