As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to offer our Copper Waterstop for Tunnel Construction Waterproofing 1.2mm x 300mm Roll. This high-quality copper waterstop is specifically engineered to provide reliable sealing in concrete joints, effectively preventing water ingress in tunnels, underground structures, and other critical infrastructure. With over two decades of experience in metal product manufacturing, we combine precision craftsmanship with durable materials to deliver a solution that meets the rigorous demands of modern construction projects.
Our copper waterstop is manufactured from pure copper, ensuring excellent corrosion resistance and long-term performance even in harsh underground environments. The 1.2mm thickness offers a balance of flexibility and strength, allowing easy installation while maintaining structural integrity under hydrostatic pressure. Each roll is 300mm wide, providing ample coverage for standard construction joints, and can be customized in length to suit specific project requirements.
Why choose our copper waterstop? It not only acts as a physical barrier but also forms a chemical bond with concrete, creating a watertight seal that outperforms many alternative materials. Whether you are working on a subway tunnel, hydroelectric project, or basement waterproofing, this product is designed to deliver consistent results.
Key Features & Benefits
- Superior Waterproofing: The copper waterstop creates a reliable barrier against water seepage, even under high hydrostatic pressure.
- Corrosion Resistance: Copper naturally resists corrosion, ensuring decades of service life in wet or chemically aggressive soils.
- Flexible & Durable: The 1.2mm thickness allows the strip to conform to joint movements without cracking, while maintaining tensile strength.
- Easy Installation: Supplied in rolls, it can be cut and positioned quickly on-site, reducing labor time and costs.
- Compatibility with Concrete: Copper bonds well with concrete, eliminating the need for additional adhesives or mechanical fasteners.
- Customizable Dimensions: Length and width can be tailored to meet specific project specifications (available upon request).
- Eco-Friendly: Copper is 100% recyclable, contributing to sustainable construction practices.

Frequently Asked Questions
1. What is the standard length of each roll?
Our standard roll length is 20 meters, but we can produce custom lengths according to your project needs. Please inform us of your required length when placing an order.
2. Can this copper waterstop be used in saltwater environments?
Yes, copper has excellent resistance to corrosion in both fresh and saltwater conditions. However, for extremely aggressive chemical environments, we recommend consulting our technical team for compatibility.
3. How is the waterstop installed in concrete joints?
The copper waterstop is placed in the middle of the construction joint, embedded half in the first concrete pour and half in the second. It should be positioned securely and supported to prevent displacement during pouring. Detailed installation guidelines are available upon request.
4. Is the copper waterstop flexible enough for curved tunnel sections?
Yes, the 1.2mm thickness provides sufficient flexibility to conform to curved surfaces without cracking. For tight radii, we recommend cutting the strip into shorter segments or using our pre-formed corner pieces (available on request).
5. Do you provide samples before bulk order?
Absolutely. We can send free samples (shipping cost may apply) for your evaluation. Please contact our sales team to arrange sample delivery.
