1. Core Features

Premium Material Performance: The flexible PVC composite delivers a tensile strength of ≥12MPa and elongation at break of ≥250%, exceeding the basic requirements of GB/T 18173.2-2014 Polymer Waterproof Materials - Part 2: Waterstops . It retains excellent elasticity across -30℃ to 60℃, withstanding low-temperature bending (-20℃) without cracking and high-temperature exposure without brittleness . The water absorption rate is ≤0.5%, ensuring stable performance in long-term humid environments, while strong resistance to acids, alkalis, and salts suits corrosive settings like sewage treatment tanks and chemical workshops .

Specialized W-Type Structure: The 300mm width optimizes coverage for large joints in underground engineering and water conservancy facilities, with common thickness options of 4mm, 6mm, 8mm, and 10mm (customizable per project needs) . The W-shaped central core enhances radial compression and longitudinal tensile capacity to absorb structural settlement and expansion, while wings feature diamond-shaped anti-skid ribs that increase bonding force with concrete by 30% compared to smooth surfaces, preventing displacement during pouring . This dual-design creates a multi-layer barrier against water migration, even under medium-to-high water pressure.

Rigorous Performance Compliance: Shore A hardness measures 65±5, balancing rigidity for installation and flexibility for deformation . After 72 hours of hot air aging at 70℃, tensile strength retention exceeds 80% and elongation at break retention reaches ≥240%, ensuring long-term durability . It meets flammability rating V-0 and passes microbial erosion resistance tests, avoiding performance degradation in damp conditions .

2. Application Scenarios

Ideal for projects with large-width joints and high waterproof demands, including:

Water conservancy projects: Small-to-medium reservoir dam joints, irrigation channel connection seams, culvert expansion joints, and structural seams ;

Municipal engineering: Underground utility tunnel construction joints, rainwater regulation tank circumferential seams, subway station platform expansion joints, and tunnel joints ;

Industrial facilities: Workshop floor joints, medium-to-large storage tank (50-500m³) seams, and sewage treatment pool structural joints ;

Civil construction: High-rise building basement floor/wall joints, retaining wall expansion seams, and prefabricated component connections .

It performs reliably in environments with medium-to-high water pressure (≤0.5MPa), alternating dry-wet cycles, or mild chemical exposure.

3. Installation and Advantages

Efficient Construction: The 300mm width and flexible texture allow easy cutting and bending for linear, curved, and corner joints—no special tools required . Installation uses simple steel bar clamping or template pressing, while joints are sealed via hot welding or specialized PVC adhesive for system integrity . Compatibility with standard concrete pouring reduces construction time by 15-20% compared to complex waterproof systems .

Cost-Effective Durability: Insoluble in water, oils, and common solvents, the product maintains performance for over 30 years under normal use, minimizing maintenance costs . Its wide-width design reduces the number of joints in large projects, lowering material waste and labor costs—offering 25% higher cost-effectiveness than narrower alternatives for large-joint applications .

Reliable Quality Assurance: Each batch undergoes third-party testing for tensile strength, low-temperature flexibility, and corrosion resistance . Packaged in 20m or 25m rolls (customizable) with moisture-proof film, it ensures easy transportation and on-site storage, fully meeting GB 50208-2022 Code for Acceptance of Construction Quality of Building Waterproofing Engineering requirements .
