PVC WATERSTOPPER C240 - 1：Reliable Leak - Proof Solution for Concrete Joints
Easy - to - Install PVC WATERSTOPPER C240 Designed to Withstand Concrete Pressure During Pouring
1. Core Features
(1) Premium Material & Stable Performance
Adopts high-quality flexible PVC composite (free of reclaimed materials) that meets industry performance standards, with key indicators verified by authoritative 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 brittle temperature ≤-30℃ (no cracking in low-temperature bending tests) and no brittleness under high-temperature exposure, adapting to diverse climatic conditions from cold plateaus to hot coastal areas ;
- 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 .
(2) Specialized C-Shaped Structure
The 240mm width (tolerance: ±7.0mm for standard batches) optimizes coverage for medium joints, eliminating waterproof blind spots while avoiding material waste. The C-type profile (standard thickness: 5.0±0.5mm) features :
- Curved elastic core: The C-shaped central body absorbs horizontal and vertical displacement up to 15mm, effectively adapting to concrete expansion and settlement—more flexible than flat sealing materials ;
- Reinforced bonding flanges: 6-8mm thick flanges on both sides, equipped with diamond-shaped anti-skid ribs (height ≥10mm) and pre-punched brass eyelets. The ribs increase bonding force with concrete by 35% compared to smooth surfaces, while the eyelets enable secure fixing to steel reinforcement ;
- Balanced hardness: Shore A hardness of 70±5, 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 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 (≤0.6MPa) 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 basements, and underground car park construction joints (paired with split formwork for optimal installation) ;
- Water conservancy projects: Small irrigation channels, farmland water conservancy ponds, culverts, and small reservoir expansion joints (resistant to sewage and irrigation water erosion) ;
- 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 (≤150m³) .
3. Installation & Advantages
(1) Efficient Construction & Compatibility
- Simplified fixing: The pre-punched eyelets in flanges allow quick attachment to steel reinforcement with tie wires, or direct pressing with split formwork—avoiding displacement during concrete pouring ;
- Easy on-site welding: Butt joints are seamlessly welded using a thermostatically controlled welding iron (240V). Factory-welded L/T-shaped pieces are 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 240mm width reduces waste by 20% compared to 280mm-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 grouting without large-scale demolition ;
- Long-term value: A single installation provides over 30 years of waterproof protection, with total cost 40% lower than frequent replacement of ordinary sealants .
(3) Reliable Supply & After-Sales
- Packaging & delivery: Supplied in 20-25m rolls (custom lengths available), packaged in moisture-proof polyethylene film to avoid sun exposure and rain damage. Monthly supply capacity reaches 100,000 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 .
