PVC WATERSTOPPER W200-1 Leakproof for Concrete Joints Basements Tanks

1. Core Features

• Premium Material PerformanceThe product adopts a high-quality flexible PVC composite formula, achieving a tensile strength of ≥10MPa and an elongation at break of ≥250%—fully complying with the mandatory requirements of GB/T 18173.2-2014 Polymer Waterproof Materials - Part 2: Waterstops . It retains excellent elasticity across a wide temperature range of -35℃ to 60℃, withstanding low-temperature bending tests at -20℃ without cracking and resisting brittleness under high-temperature exposure . With a water absorption rate ≤0.5%, it maintains stable performance in long-term humid environments, while its strong chemical resistance allows it to withstand erosion from weak acids, alkalis, and common municipal sewage . This material stability ensures no performance degradation even in harsh or corrosive settings.
• Specialized W-Type StructureThe 200mm width is optimized for standard-sized joints in residential and municipal projects, avoiding material waste while ensuring full coverage of seam areas . The W-shaped central core enhances radial compression and longitudinal tensile capacity, enabling it to absorb structural settlement and thermal expansion without losing sealing effectiveness . The extended wings (5-8mm thick, customizable) feature diamond-shaped anti-skid ribs that increase bonding force with concrete by 30% compared to smooth surfaces, preventing displacement during pouring and ensuring tight integration with the structure . This dual-design creates a multi-layer barrier against water migration, even under medium water pressure.
• Rigorous Performance ComplianceThe product has a Shore A hardness of 65±5, balancing rigidity for easy installation and flexibility for deformation . After 72 hours of hot air aging at 100℃, its tensile strength retention rate exceeds 80%, demonstrating superior anti-aging durability for long-term use . It meets the V-0 flammability rating (UL94 standard) and passes microbial erosion resistance tests, avoiding mold growth or performance decline in damp environments . All indicators fully align with industry standards for waterproofing engineering acceptance.

2. Application Scenarios

• Civil construction: High-rise building basement floor/wall joints, retaining wall expansion seams, prefabricated component connections, and balcony waterproof edges ;
• Municipal engineering: Underground utility tunnel construction joints, rainwater collection tanks, sidewalk expansion joints, and small sewage lifting stations ;
• Light industrial facilities: Workshop floor joints, small-to-medium storage tank (≤50m³) circumferential seams, and equipment foundation waterproof joints ;
• Water conservancy accessories: Small irrigation channel joints, farmland water conservancy pond seams, and culvert branch connections .

3. Installation and Advantages

• Efficient and Convenient ConstructionThe 200mm width and flexible texture allow easy cutting and bending to fit linear, curved, or corner joints—no special tools required . Installation is completed via simple steel bar clamping or template pressing, and on-site joints can be sealed with hot welding (using a standard PVC welding gun) or specialized adhesive, ensuring the integrity of the waterproof system . Its compatibility with standard concrete pouring processes reduces the joint waterproofing construction time by 15-20% compared to complex alternatives.
• Cost-Effective DurabilityInsoluble in water, oils, and common solvents, the product maintains stable waterproof performance for over 30 years under normal use, significantly reducing long-term maintenance costs . The 200mm width balances coverage and material efficiency, reducing waste in standard-joint projects and offering 20-25% higher cost-effectiveness than wider waterstops .
• Reliable Quality AssuranceEach batch undergoes third-party testing for tensile strength, low-temperature flexibility, and corrosion resistance, with a 100% qualification rate . Finished products are packaged in 20m or 25m rolls (customizable) with moisture-proof film, facilitating transportation and on-site storage . It fully meets the requirements of GB 50208-2022 Code for Acceptance of Construction Quality of Building Waterproofing Engineering, ensuring compliance and reliability for project acceptance.
