PVC WATERSTOPPER C220 - 1: Superior Waterproofing Solution for Concrete Joints
Specifically Designed for Working Joints and Expansion Joints, with a Width of 220mm
1. Material & Stable Performance
Adopts high-quality flexible PVC composite (free of reclaimed materials) that meets CNS 3895-1990 and industry performance standards, with key indicators verified by testing :
- Mechanical strength: Tensile strength ≥12MPa (up to 17MPa for high-grade batches), elongation at break ≥300%, and tear strength ≥25kN/m—ensuring resistance to tearing during concrete pouring and structural deformation ;
- Temperature adaptability: Operating range of -30℃ to 65℃, with no cracking in low-temperature bending tests (brittle temperature ≤-30℃) and no brittleness under high-temperature exposure, adapting to diverse climatic conditions ;
- Environmental resistance: Water absorption rate ≤0.5%, maintaining stability in long-term submerged environments. It resists erosion from weak acids (pH 3-10), alkalis, and municipal sewage, suitable for sewage treatment pools and underground projects ;
- Aging durability: After 70℃×72h hot air aging, tensile strength retention ≥83% (≥10MPa) and elongation at break retention ≥240%, ensuring a service life of over 30 years in underground or shaded environments .
- Specialized C-Shaped Structure
The 220mm width (tolerance: ±6.5mm) optimizes coverage for medium joints, eliminating waterproof blind spots while avoiding material waste. The C-type profile (thickness: 4.0±0.5mm for standard models) features :
- Curved elastic core: The C-shaped central body absorbs horizontal and vertical displacement up to 12mm, effectively adapting to minor expansion and settlement of concrete structures—more flexible than flat sealing materials ;
- Reinforced bonding flanges: 5-7mm thick flanges on both sides, often equipped with anti-skid ribs (height ≥10mm) to increase bonding force with concrete by 30% compared to smooth surfaces, preventing displacement during pouring ;
- Balanced hardness: Shore A hardness of 75±5, striking a balance between rigidity for stable positioning during construction and flexibility for deformation absorption after concrete hardening .
- Rigorous Quality Compliance
- Meets CNS 3895-1990 standards for C-type PVC waterstops, with each batch undergoing third-party testing for hardness, tensile strength, and low-temperature flexibility—achieving a 100% qualification rate ;
- Passes hydrostatic pressure resistance tests, effectively blocking medium water pressure (≤0.5MPa) penetration—suitable for basements and small reservoirs ;
- Weldable via hot-melt technology (welding temperature ≥140℃), enabling seamless on-site joints that maintain the same waterproof performance as the main body .
2. Application Scenarios
Ideal for medium-joint waterproofing in concrete structures with minor-to-moderate deformation:
- Municipal engineering: Underground utility tunnels, rainwater regulation tanks, subway station auxiliary structures, and underground car park construction joints ;
- Water conservancy projects: Small irrigation channels, farmland water conservancy ponds, culverts, and small reservoir expansion joints (paired with mastic for enhanced waterproofing) ;
- Civil construction: High-rise building basements, retaining walls, lift shafts, and prefabricated concrete component joints ;
- Special facilities: Swimming pools (resistant to chlorine corrosion), sewage treatment plants, and small industrial storage tanks (≤100m³) .
3. Installation & Advantages
- Efficient Construction & Compatibility
- Simplified fixing: The flanges can be fixed to steel reinforcement with tie wires or pressed with split formwork. Care should be taken to keep the C-shaped core centered in the joint to ensure displacement absorption ;
- Easy on-site welding: Butt joints are seamlessly welded using a thermostatically controlled welding iron (240V). For bends, factory-welded L/T-shaped pieces are recommended 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 .
- Cost-Effective & Low Maintenance
- Material efficiency: The 220mm width reduces waste by 25% compared to 250mm-wide alternatives for medium joints, lowering material costs ;
- Minimal maintenance: The durable PVC material and reliable bonding with concrete minimize repair needs. Leakage (if any) can be easily addressed via local 注浆 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 .
- Reliable Supply & After-Sales
- Packaging & delivery: Supplied in 20m rolls (custom lengths available), packaged in moisture-proof film to avoid sun exposure and rain damage. 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 cross-section 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 .
