PVC WATERSTOPPER WB250-1 Leakproof for Concrete Basement Joints

Leakproof Flexible PVC WATERSTOPPER WB250-1 - Fit for Basement Concrete Joints

Ideal for projects with medium-width joints and moderate waterproof demands, including:

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

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

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

Industrial facilities: Workshop floor joints, medium-sized storage tank seams, and sewage treatment pool structural joints .

It performs reliably in environments with medium water pressure (≤0.4MPa), alternating dry-wet cycles, or mild chemical exposure.

3. Installation and Advantages

Efficient Construction: The 250mm width and flexible texture allow easy cutting and bending for linear, curved, and corner joints . Installation uses simple steel bar clamping or template pressing , while joints are sealed via hot welding or 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 and oils , the product maintains performance for over 30 years under normal use , minimizing maintenance costs. Its medium-width design balances material efficiency and coverage, offering 25% higher cost-effectiveness than wider alternatives for medium-joint projects.

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