Durable PVC WATERSTOPPER KC - 310: Ensuring Reliable Leak - Proofing in Concrete Joints
Features Superior Resistance to Corrosion, Weathering, and Chemicals
1. Core Features
(1) Premium Composite Material & Superior Performance
Adopting high-quality flexible PVC composite (free of reclaimed materials), the product meets strict industry performance benchmarks, with key indicators validated by authoritative testing :
- Mechanical Strength: Tensile strength ≥12MPa (up to 15MPa 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 -35℃ to 65℃, with brittle temperature ≤-35℃ . It withstands low-temperature bending without cracking and high-temperature exposure without brittleness, 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 resists erosion from weak acids (pH 3-10), alkalis, municipal sewage, and seawater, suitable for sewage treatment plants and coastal 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 35 years in underground or shaded environments.
(2) Specialized KC-Type Composite Structure
The 310mm width (tolerance: ±9.0mm for standard batches) optimizes coverage for large joints, eliminating waterproof blind spots while avoiding material waste. The KC-type profile (standard thickness: 6.0±0.5mm) integrates three functional components :
- Reinforced Curved Elastic Core: The KC-type central body (enhanced with internal rib reinforcement) absorbs horizontal and vertical displacement up to 20mm—30% higher than ordinary C-type 止水带 —effectively adapting to large concrete expansion and settlement.
- Dual-Layer Bonding Flanges: 7-9mm thick flanges with diamond-shaped anti-skid ribs (height ≥12mm) and pre-punched stainless steel eyelets. The ribs increase bonding force with concrete by 40% compared to smooth surfaces, while eyelets enable secure fixing to steel reinforcement .
- Balanced Hardness: Shore A hardness of 72±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 GB/T 18173.2-2014 and GB 50208-2011 standards , with each batch undergoing third-party testing for hardness, tensile strength, low-temperature flexibility, and aging resistance—achieving a 100% qualification rate.
- Passes hydrostatic pressure resistance tests, effectively blocking high water pressure (≤0.8MPa) penetration—suitable for deep basements, reservoirs, and tunnels .
- Weldable via hot-melt technology (welding temperature 140-160℃), enabling seamless on-site joints that maintain the same waterproof performance as the main body .
2. Application Scenarios
Ideal for large-joint waterproofing in high-demand concrete structures:
- Municipal Engineering: Underground utility tunnels, large rainwater regulation tanks, subway station main structure joints, and underground car park expansion seams (paired with split formwork for optimal installation).
- Water Conservancy Projects: Medium-sized reservoirs, irrigation channels, culverts, and dam auxiliary structure joints (resistant to sewage and irrigation water erosion ).
- Civil Construction: Super high-rise building basements, retaining walls, and prefabricated concrete component large joints.
- Special Facilities: Large sewage treatment pools, industrial storage tanks (≤300m³), and tunnel construction joints.
3. Installation & Advantages
(1) Efficient Construction & Compatibility
- Simplified Fixing: Pre-punched stainless steel 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 and ensure joint reliability.
- 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 310mm width reduces waste by 20% compared to 350mm-wide alternatives for large joints, lowering material costs .
- Minimal Maintenance: The durable PVC material and reliable bonding with concrete minimize repair needs. If leakage occurs, local grouting can address issues without large-scale demolition .
- Long-Term Value: A single installation provides over 35 years of waterproof protection, with total cost 45% 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 120,000 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: 5-year warranty against material defects (e.g., uneven thickness, reduced elasticity). Non-human-caused quality issues are eligible for free replacement.
