As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to present our 1.2mm Thin Copper Waterstop, 100mm Width, with an optional PVC Coated version for enhanced corrosion resistance. Our factory, established in 1998, has been exporting high-quality waterstop products to more than 20 countries worldwide, including North America, Europe, and Southeast Asia, with an annual export value of US$5-10 million. This copper waterstop is designed to provide reliable waterproofing in concrete construction joints, ensuring long-term durability and structural integrity.
Our thin copper waterstop features a precise 1.2mm thickness and 100mm standard width, making it ideal for applications where space is limited yet high-performance sealing is required. The optional PVC coating offers an additional layer of protection against corrosive environments, such as sewage treatment plants, marine structures, and chemical storage facilities. The combination of copper's natural antimicrobial properties and the PVC coating's chemical resistance makes this product a versatile solution for various construction projects.
Key Features & Benefits
- Thin Profile (1.2mm): Easy to install in narrow joints, reduces material waste, and maintains flexibility during concrete movement.
- Standard Width (100mm): Compatible with most concrete joint designs, available in other widths upon request.
- PVC Coated Option: Provides excellent resistance to acids, alkalis, salts, and UV radiation, extending service life in harsh environments.
- High Ductility: Copper can be bent and shaped on-site without cracking, ensuring a tight seal around rebar and irregular surfaces.
- Corrosion Resistance: Copper naturally resists corrosion in soil and water; the PVC coating adds an extra barrier for aggressive media.
- Easy Joining: Copper waterstop sections can be welded or soldered together for continuous lengths, and the PVC coating can be stripped for welding.
- Long Service Life: Proven track record in dams, tunnels, basements, and water treatment plants for decades.

Frequently Asked Questions
-
Q: What is the difference between plain copper waterstop and PVC coated copper waterstop?
A: Plain copper waterstop offers natural corrosion resistance and is suitable for most general applications. The PVC coated version provides an additional barrier against aggressive chemicals, acids, and alkalis, making it ideal for wastewater treatment plants, chemical plants, and marine environments. -
Q: Can the PVC coating be removed for welding?
A: Yes. The PVC coating can be easily stripped at the joint area using a utility knife or heat gun. After welding or soldering, the coating can be repaired with PVC tape or shrink tubing if needed. -
Q: What is the maximum length of each piece?
A: Standard length is 3 meters. We can produce custom lengths up to 6 meters per piece. For continuous installations, sections can be welded together on-site. -
Q: Is this waterstop suitable for use in seawater?
A: Yes, copper is naturally resistant to seawater corrosion. The PVC coated version offers even better protection in highly saline environments. However, for long-term immersion in seawater, we recommend consulting with our engineers for specific project requirements. -
Q: How do you ensure the product meets quality standards?
A: We conduct in-house testing for thickness, width, tensile strength, and elongation. Each batch is also inspected visually for surface defects. We can provide a mill test certificate upon request. -
Q: Can you provide samples before bulk order?
A: Yes, we offer free samples for your evaluation (shipping cost may apply). Lead time for samples is typically 3-5 working days. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard copper waterstop is 100 kg. For custom sizes or PVC coated options, please contact us for details. -
Q: How long does delivery take?
A: For standard products, delivery is usually 15-20 days after order confirmation. For customized orders, it may take 20-30 days depending on quantity and specifications.
