PVC WATERSTOP C250: Ideal for Durable Waterproofing in Various Building Projects

It Has a Good Adhesion to Concrete, Lasting Waterproofing and Preventing Water Leakage Efficiently.
1. Core Features
(1) Standard-Compliant Material & Performance
Adopting high-quality PVC composite (free of reclaimed materials), the product meets strict industry benchmarks with verified test data :
  • Mechanical Strength: Tensile strength reaches 15.7 N/mm² (15.7MPa) — exceeding the 12MPa industry minimum — with elongation at break ≥300% and tear strength ≥25kN/m . It resists tearing during concrete pouring and structural movement.
  • Temperature Adaptability: Operating range of -30℃ to 65℃, with brittle temperature ≤-30℃. It maintains flexibility in cold climates and avoids brittleness in high temperatures, adapting to diverse regions.
  • Environmental Resistance: Water absorption rate ≤0.5%, ensuring stability in long-term submerged environments. It resists weak acids (pH 3-10), alkalis, and municipal sewage, suitable for sewage treatment plants .
  • Aging Durability: After 70℃×72h hot air aging, tensile strength retention ≥85% and elongation retention ≥250%, guaranteeing a service life of over 30 years in underground or shaded areas .
(2) Specialized C-Shaped Structure (WS-C-2 Specification)
Following CNS 3895-1990 standards, the C250 features a precision-engineered profile :
  • Dimensional Precision: 250mm width (tolerance: ±7.5mm) and 6.0mm thickness (tolerance: ±0.6mm) — ideal for joints requiring wider coverage than 240mm models but avoiding waste of 300mm alternatives .
  • Curved Elastic Core: The C-shaped central body absorbs horizontal/vertical displacement up to 10mm , effectively adapting to concrete expansion and settlement. Its arc design outperforms flat waterstops in dynamic joint scenarios.
  • Reinforced Bonding Flanges: 7-9mm thick flanges with diamond-shaped anti-skid ribs (height ≥14mm ) increase concrete bonding force by 40% compared to smooth surfaces. Pre-punched eyelets (optional) enable secure fixing to steel reinforcement, preventing displacement during pouring .
  • Balanced Hardness: Shore A hardness of 78 IRHD , balancing rigidity for installation stability and flexibility for deformation absorption.
(3) Quality & Compliance
  • Certifications: Meets ISO/21 CFR 175:300 and CNS 3895-1990 standards , with each batch passing third-party tests for tensile strength, low-temperature flexibility, and hydrostatic resistance.
  • Water Pressure Resistance: Withstands 10m hydrostatic head (≈0.1MPa) , suitable for basements, water tanks, and small reservoirs.
  • Weldable Joints: Hot-melt welding (140-160℃) creates seamless joints with identical performance to the main body, ensuring no leakage at connections .
2. Application Scenarios
Tailored for medium-to-large joints in diverse projects :
  • Water Conservancy Projects: Medium irrigation channels, farmland ponds, and reservoir auxiliary structures — resistant to long-term submerged erosion.
  • Municipal Engineering: Underground utility tunnels, rainwater regulation tanks, and subway station basements — paired with split formwork for optimal installation.
  • Civil Construction: High-rise building basements, retaining walls, and prefabricated component joints — adapting to structural settlement.
  • Special Facilities: Sewage treatment pools, industrial storage tanks (≤200m³), and tunnel construction joints — withstanding chemical corrosion and water pressure.
3. Installation & Advantages
(1) Efficient Construction
  • Simplified Fixing: Pre-punched eyelets (optional) allow quick attachment to steel reinforcement with tie wires; alternatively, split formwork presses the flanges to prevent displacement .
  • On-Site Welding: Use a 240V thermostatically controlled welding iron for seamless joints. Factory-supplied L/T-shaped pre-welded pieces reduce on-site workload by 30% .
  • Concrete Compatibility: Works with all standard concrete mixes, activating waterproof performance immediately after concrete hardening (no extra curing time) .
(2) Cost-Effectiveness
  • Material Efficiency: 250mm width cuts waste by 20% vs. 300mm models for matching joints, lowering material costs .
  • Low Maintenance: Durable PVC and strong concrete bonding minimize repairs. Local grouting resolves leaks without large-scale demolition .
  • Long-Term Value: 30+ year service life reduces total cost by 40% compared to replacing ordinary sealants every 5-8 years .
(3) Supply & After-Sales
  • Packaging & Delivery: Supplied in 12m/15m rolls (custom lengths available) , wrapped in moisture-proof plastic to avoid sun/rain damage. Monthly supply capacity: 100,000 meters, with 7-day delivery after payment .
  • Technical Support: Free provision of installation guides, welding videos, and cross-section drawings. On-site consultation available for large projects.
  • Warranty: 3-year warranty for material defects (e.g., uneven thickness, reduced elasticity). Non-human-caused issues qualify for free replacement .
Note: For detailed test reports, custom thickness (5-8mm), or color options (standard blue/black ), contact customer service for tailored solutions!
