Leakproof Flexible PVC WATERSTOPPER WO230-1 - Fit for Basement Concrete Joints

1. Core Features

Premium Material Performance: Adopting high-quality flexible PVC composite, the product achieves a tensile strength of ≥10MPa and an elongation at break of ≥250%, fully complying with GB/T 18173.2-2014 Polymer Waterproof Materials - Part 2: Waterstops . It maintains excellent elasticity within the temperature range of -35℃ to 60℃, with no cracking in low-temperature bending tests and no brittleness under high temperatures . The water absorption rate is ≤0.5%, ensuring stable performance even in long-term humid environments , and it exhibits strong resistance to acids, alkalis, salts, and common chemical media .

Specialized WO-Type Structure: The 230mm width design provides comprehensive coverage of standard and medium-width structural joints. The WO-type cross-section combines an O-shaped central core and reinforced wings: the O-core enhances radial compression and deformation capacity to accommodate structural settlement, while the extended wings with anti-skid convex lines increase friction with concrete, preventing displacement during pouring . The thickness ranges from 5mm to 8mm (customizable) to adapt to different water pressure conditions , and the multi-rib profile of the wings forms an impenetrable barrier against water migration .

Rigorous Performance Compliance: The Shore A hardness measures 65±5, and after 72 hours of hot air aging at 100℃, the tensile strength retention rate exceeds 80%, demonstrating superior anti-aging properties . It meets the acceptance requirements of JGJ 333-2014 Technical Specification for Waterproofing of Underground Engineering for installation and durability , with a flammability rating of V-0 for enhanced safety .

2. Application Scenarios

The product is ideal for various engineering scenarios requiring reliable joint waterproofing, including:

Water conservancy projects: Reservoir walls, culvert expansion joints, and irrigation channel connection seams ;

Underground engineering: Metro station platform settlement joints, underground utility tunnel construction joints, and basement exterior wall expansion joints ;

Municipal & industrial projects: Sewage treatment tank circumferential seams, swimming pool structural joints, and chemical workshop floor joints ;

Civil construction: High-rise building basement floor joints and retaining wall expansion joints .

It performs exceptionally well in environments with long-term water pressure, alternating dry-wet conditions, or mild chemical erosion .

3. Installation and Advantages

Efficient Construction: The material is flexible and can be cut arbitrarily according to joint lengths, easily adapting to linear, curved, and corner shapes . Installation is achievable via steel bar clamping or formwork pressing without special tools. Joint connections can be site-welded with a welding knife or bonded with specialized PVC adhesive, ensuring the integrity of the waterproof system . It is highly compatible with concrete pouring processes, effectively shortening the construction period .

Cost-Effective Durability: With strong resistance to microbial erosion and insolubility in water and common oils , the product maintains stable performance for over 30 years under normal use, significantly reducing long-term maintenance costs . Compared to rubber waterstops, it offers higher cost-effectiveness and is more suitable for large-area applications .

Reliable Quality Assurance: Each batch undergoes third-party testing for tensile strength, low-temperature flexibility, and chemical resistance . The finished products are packaged in 20m or 25m rolls (customizable) for convenient transportation and on-site use , fully meeting the acceptance standards of GB 50108-2008 Technical Specification for Waterproofing of Underground Engineering .
