PVC WATERSTOPPER V200-1 - High - Performance Waterproof Solution for Concrete Joints

1. Core Features

• Premium Material PerformanceAdopts high-quality flexible PVC composite, achieving a tensile strength of ≥10MPa and elongation at break of ≥250%—fully complying with GB/T 18173.2-2014 Polymer Waterproof Materials - Part 2: Waterstops. It retains elasticity across -35℃ to 60℃, withstanding -20℃ low-temperature bending without cracking and high-temperature exposure without brittleness. The water absorption rate is ≤0.5%, ensuring stability in long-term humid environments, and it resists erosion from weak acids, alkalis, and municipal sewage, avoiding performance degradation in corrosive settings.
• Specialized V-Type StructureThe 200mm width optimizes coverage for standard joints in residential and municipal projects, reducing material waste. The V-type (triangular) central core enhances radial compression and lateral shear resistance, effectively absorbing structural expansion or settlement to prevent seal failure. The 5-7mm thick wings (customizable) feature anti-skid convex ribs, increasing bonding force with concrete by 30% compared to smooth surfaces and preventing displacement during pouring.
• Rigorous Performance ComplianceShore A hardness measures 65±5, balancing rigidity for installation and flexibility for deformation. After 72 hours of hot air aging at 100℃, tensile strength retention exceeds 80%, ensuring long-term durability. It meets the V-0 flammability rating (UL94 standard) and passes microbial erosion tests, avoiding mold growth in damp conditions. All indicators align with industry waterproofing engineering standards.

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 segment 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 ConstructionFlexible texture allows easy cutting and bending for linear, curved, or corner joints—no special tools required. Installation uses steel bar clamping or template pressing; on-site joints can be sealed with hot welding (300W PVC welding gun) or specialized adhesive, ensuring waterproof system integrity. Compatible with standard concrete pouring, reducing construction time by 15-20%.
• Cost-Effective DurabilityInsoluble in water, oils, and common solvents, maintaining performance for over 30 years under normal use and minimizing maintenance costs. The 200mm width balances coverage and material efficiency, offering 20-25% higher cost-effectiveness than wider waterstops for standard-joint projects.
• Reliable Quality AssuranceEach batch undergoes third-party testing for tensile strength, low-temperature flexibility, and corrosion resistance (100% qualification rate). Packaged in 20m/25m rolls (customizable) with moisture-proof film for easy transportation and storage. Fully meets GB 50208-2022 Code for Acceptance of Construction Quality of Building Waterproofing Engineering requirements.
