Founded in 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-quality copper waterstops for over two decades. Our Tunnel and Dam Copper Waterstop, 1.5mm thickness, 300mm width, is engineered to provide reliable, long-term sealing in the most demanding civil engineering projects. With an annual export value exceeding US$5 million and shipments to major ports like Tianjin, Qingdao, and Shanghai, we supply this product to contractors and engineers across North America, Europe, Southeast Asia, and the Middle East. This copper waterstop is specifically designed to resist soil corrosion, ensuring the integrity of concrete joints in tunnels, dams, and underground structures.
Key Features & Technical Specifications
- Pure Copper Material – Made from high-grade copper (Cu > 99.9%), offering exceptional ductility and resistance to aggressive soil environments.
- Optimal Dimensions – 1.5mm thickness provides a balance between flexibility and structural strength; 300mm width covers most joint designs effectively.
- Soil Corrosion Resistance – Copper naturally forms a protective patina layer, resisting sulfates, chlorides, and other chemicals commonly found in soil and groundwater.
- Easy Installation – Can be bent, cut, and welded on-site using standard copper welding techniques, saving time and labor costs.
- Customizable Lengths – Available in rolls (up to 30m per roll) or pre-cut lengths to match your project requirements.
- Long Service Life – Proven performance in hydraulic structures for decades without deterioration.
| Parameter | Specification | Note |
|---|---|---|
| Material | Copper (Cu) – purity ≥ 99.9% | Meets international standards |
| Thickness | 1.5 mm (±0.05 mm) | Uniform across the width |
| Width | 300 mm (±2 mm) | Other widths (200–500 mm) available |
| Tensile Strength | ≥ 200 MPa | High ductility for stress absorption |
| Elongation | ≥ 30% | Allows for joint movement |
| Corrosion Resistance | Excellent in soil, acidic/alkaline environments | Tested per ASTM B152 |
Advantages for Your Project
- Enhanced Watertightness – The copper waterstop creates a continuous barrier against water penetration, preventing leaks in tunnel linings and dam construction joints.
- Resistance to Soil Corrosion – Unlike steel or PVC, copper does not rust or degrade when exposed to moist soil, chlorides, or sulfates, ensuring decades of reliable sealing.
- Flexibility & Adaptability – Can be easily shaped to follow irregular joint profiles, including expansion joints, contraction joints, and construction joints.
- Compatibility with Concrete – Copper bonds well with concrete, and the waterstop can be embedded halfway into the joint for optimal performance.
- Cost-Effective Over Time – Minimal maintenance and replacement needs reduce lifecycle costs compared to alternative materials.

Frequently Asked Questions
- How is the copper waterstop installed? – The waterstop is typically placed at the concrete joint, with half its width embedded in the first pour and the other half in the second pour. It can be tied to rebar or welded for positioning.
- Can this product be welded? – Yes, copper waterstops can be joined by brazing, oxyacetylene welding, or TIG welding. We recommend using copper filler rods for strong joints.
- What is the minimum bending radius? – For 1.5mm thick copper, the minimum bend radius is about 5 times the thickness (7.5mm) without cracking.
- Is the waterstop resistant to seawater? – Yes, copper has excellent resistance to seawater corrosion, making it suitable for coastal tunnels and dams.
- Do you offer custom widths or thicknesses? – Absolutely. We can produce widths from 150mm to 500mm and thicknesses from 1.0mm to 3.0mm upon request.
- How long does the copper last underground? – Copper waterstops have been documented to last over 50 years in aggressive soil conditions, with minimal loss of material.
- What certificates do you have? – Our products are manufactured in compliance with ASTM B152 and BS EN 1652. For specific certifications, please contact our sales team.
- Do you provide samples for testing? – Yes, we can send small samples (e.g., 300mm x 300mm) for your evaluation. A nominal fee may apply, but it is refundable with larger orders.
