Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with over two decades of expertise in metal products. Our Underground Basement Copper Waterstop 1.5mm Thick × 250mm Width × 20m Length is engineered to provide reliable water sealing for critical concrete joints in basements, tunnels, and other below-grade structures. Made from high-purity copper, this waterstop offers exceptional corrosion resistance and long-term durability, ensuring your construction stays dry and safe.
This copper waterstop is designed to be embedded in concrete construction joints, acting as a permanent barrier against water ingress. The 1.5mm thickness provides adequate rigidity while remaining flexible enough for easy on-site installation. Each roll is 20 meters long, minimizing splicing and waste. With a width of 250mm, it covers a wide joint area, making it suitable for heavy-duty waterproofing requirements.
Key Features & Technical Specifications
- Material: Pure copper (Cu ≥99.9%) – naturally resistant to rust, chemicals, and soil conditions.
- Thickness: 1.5 mm (±0.05 mm tolerance) – balances strength and workability.
- Width: 250 mm – suitable for most standard construction joints.
- Length: 20 m per roll – reduces the number of joints required.
- Surface Finish: Smooth, oxide-free finish for optimal bonding with concrete.
- Flexibility: Easily bendable to follow irregular joint contours without cracking.
- Durability: Copper’s natural patina forms a protective layer, extending service life.
- Compliance: Manufactured in accordance with international construction standards (custom specifications available upon request).

Frequently Asked Questions (FAQ)
-
Q1: What is the advantage of copper waterstop over PVC or rubber waterstops?
A: Copper waterstop offers superior durability, corrosion resistance, and longevity. It does not degrade under UV light, chemicals, or soil conditions, and it maintains its sealing properties for decades. While initial cost may be higher, the total lifecycle cost is often lower due to reduced maintenance. -
Q2: Can this waterstop be used in saltwater environments?
A: Yes, copper has excellent resistance to saltwater corrosion. However, for extreme marine conditions, we recommend consulting with our engineers for specific application advice. -
Q3: How is the waterstop installed?
A: The copper waterstop is placed at the construction joint before concrete is poured. It should be centered in the joint and held in place with wire ties or clips. The ends of each roll can be overlapped and soldered or welded for a continuous seal. -
Q4: Is the copper waterstop suitable for both horizontal and vertical joints?
A: Absolutely. The flexible copper strip can be used in both horizontal (slab) and vertical (wall) joints. It can be bent to follow complex shapes. -
Q5: What is the minimum order quantity?
A: Our standard minimum order is 100 rolls. For smaller quantities, please contact us to discuss options. -
Q6: Do you offer custom sizes?
A: Yes, we can customize thickness (from 1.0mm to 3.0mm), width (from 100mm to 500mm), and length per roll. Custom dimensions are subject to minimum order and production lead time. -
Q7: How do you ensure product quality?
A: We perform incoming material inspection, in-process checks, and final testing for thickness, width, length, tensile strength, and surface finish. Certificates of analysis are available upon request. -
Q8: What are the shipping options?
A: We ship via sea freight from Tianjin, Qingdao, Shanghai, or Foshan. Air freight and express courier are also available for small orders. Delivery time depends on destination and shipping method.
