PVC WATERSTOPPER O-210 - High - Performance Waterproofing for Concrete Joints

1. Core Features

(1) Premium Material & Stable Performance

• Mechanical strength: Tensile strength reaches 12-15 N/mm² (exceeding the ≥10 N/mm² industry baseline), elongation at break of 300%-350%, and tear strength ≥12 N/mm²—ensuring resistance to tearing during concrete pouring and structural deformation;
• Temperature adaptability: Operating range of -35℃ to +55℃, with no cracking in low-temperature bending tests and no brittleness under high-temperature exposure, adapting to harsh climates from cold plateaus to hot coastal areas;
• Environmental resistance: Water absorption rate ≤0.5%, maintaining stability in long-term submerged environments. It demonstrates permanent resistance to seawater, sewage, and road salt solutions, and temporary resistance to diluted inorganic alkalis, mineral acids, and mineral oils—suitable for sewage treatment plants and coastal projects;
• Aging durability: The added anti-aging agents extend its service life to over 30 years in underground or shaded environments (free of direct UV exposure). Proper storage (dry, shaded conditions) ensures a 5-year shelf life without performance degradation.

(2) Specialized O-Shaped Structure

• Hollow elastic bulb: The central O-shaped core (typically 15-20mm internal diameter) absorbs horizontal and vertical displacement up to 15mm, effectively adapting to expansion and settlement of concrete structures—far more flexible than flat sealing materials;
• Reinforced bonding flanges: 5-7mm thick flanges on both sides, often equipped with pre-punched eyelets for easy fixing and anti-skid ribs on the surface. These ribs increase bonding force with concrete by 30% compared to smooth surfaces, preventing displacement during pouring;
• Balanced hardness: Shore A hardness of 82-90, striking a perfect balance between rigidity for stable positioning during construction and flexibility for deformation absorption after concrete hardening.

(3) Rigorous Quality Compliance

• Meets factory standards for profile geometry and physical properties, with manufacturer test certificates provided (custom third-party testing available by agreement);
• Passes hydrostatic pressure resistance tests, effectively blocking medium water pressure (≤0.6MPa) penetration—suitable for basements and water reservoirs;
• Weldable via hot-melt technology, enabling seamless on-site joints that maintain the same waterproof performance as the main body, avoiding leakage at connection points.

2. Application Scenarios

• Municipal engineering: Underground utility tunnels, rainwater regulation tanks, subway station basements, underground car parks, and sidewalk expansion joints;
• Water conservancy projects: Small-to-medium reservoirs, irrigation channels, culverts, box 涵 interfaces, and farmland water conservancy ponds (paired with polyisobutylene mastic for enhanced waterproofing);
• Civil construction: High-rise building basements, retaining walls, lift shafts, and prefabricated concrete component joints;
• Special facilities: Swimming pools, sewage treatment plants, service pits, and industrial storage tanks (≤150m³).

3. Installation & Advantages

(1) Efficient Construction & Compatibility

• Simplified fixing: Pre-punched eyelets in the flanges allow quick attachment to steel reinforcement with tie wires, or direct pressing with split formwork. Care should be taken to avoid flattening the O-shaped bulb during formwork installation;
• Easy on-site welding: Butt joints can be seamlessly welded using a hot-melt tool (e.g., 500℃ heat gun), with prefabricated cross, T, or L-shaped pieces available to reduce on-site workload;
• Concrete compatibility: Works with all standard concrete mixes, with sealing performance activating immediately after concrete hardening—no additional curing time required.

(2) Cost-Effective & Low Maintenance

• Material efficiency: The 210mm width reduces waste by 25% compared to 250mm-wide alternatives for medium joints, lowering material costs;
• Minimal maintenance: The durable PVC-P material and reliable bonding with concrete minimize repair needs. If leakage occurs, reserved 注浆 tubes (common in box 涵 applications) allow for easy maintenance without large-scale demolition;
• Long-term value: A single installation provides decades of waterproof protection, with total cost 40% lower than frequent replacement of ordinary sealants.

(3) Reliable Supply & After-Sales

• Packaging & delivery: Supplied in 20m rolls (custom lengths available), packaged in moisture-proof film to avoid damage during transportation. Monthly supply capacity reaches 80,000 meters with a 5-7 day lead time;
• Technical support: Free provision of installation guides, welding operation videos, and profile drawings. On-site technical consultation is available for large projects;
• Quality guarantee: 3-year warranty against material defects (e.g., uneven thickness, reduced elasticity). Non-human-caused quality issues are eligible for free replacement.
