PVC WATERSTOPPER O - 250: High - Quality Circular Waterproofing Solution
Offering Excellent Elasticity and Strong Resistance to Hydrostatic Pressure
2.1 Core Features (Focus on Shelf Appeal)
(1) Premium Material & Reliable Performance
- Mechanical Strength: Tensile strength ≥13MPa (exceeds industry standard of 12MPa), elongation at break ≥300%, tear strength ≥28kN/m—resists tearing during concrete pouring and structural movement, ensuring no breakage in on-site construction.
- Environmental Adaptability: Brittle temperature ≤-35℃ (no cracking in low-temperature bending tests), high-temperature resistance up to 65℃ (no softening or brittleness). Water absorption rate ≤0.15%, stable in long-term submerged environments; resists weak acids (pH 3-10), alkalis, and municipal sewage—suitable for harsh scenarios like sewage treatment plants.
- Durable Aging Resistance: After 70℃×168h hot-air aging, tensile strength retention ≥88% and elongation retention ≥260%, ensuring a service life of over 30 years in underground or shaded environments—reducing long-term replacement costs for buyers.
(2) O-Shaped Structure & 250mm Width Advantage
- Hollow O-Core: The central hollow design absorbs 18mm of multi-directional displacement (20% higher than flat waterstops), avoiding leakage caused by concrete expansion/settlement—ideal for dynamic joints in high-rise basements or water tanks.
- 250mm Wide Flanges: Equipped with 4-6 diamond-shaped anti-skid ribs (height ≥10mm) on both sides, increasing bonding force with concrete by 35% compared to smooth surfaces. The width covers medium joints in one piece, reducing the number of welds by 30% vs. 200mm narrow models, lowering construction workload.
- Precise Dimensions: Width tolerance ±7.5mm, standard thickness 5.0±0.5mm (customizable 4-8mm), each roll 20-25m—fits most project batch needs, minimizing material waste.
(3) Compliance & Easy Construction
- Quality Certifications: Meets GB/T 18173.2-2014 (Chinese standard) and ISO/21 CFR 175:300 (international food-contact safety), passing hydrostatic pressure tests (withstands 10m water height)—suitable for domestic water tanks and drinking water projects.
- Simple Installation: Can be cut with a utility knife; on-site joints are sealed via hot-melt welding (140-160℃) using a common PVC welding gun—no professional equipment required. Pre-punched brass eyelets (optional) enable quick fixing to steel reinforcement, preventing displacement during concrete pouring.
2.2 Application Scenarios (Target Buyer Needs)
Perfect for medium-joint waterproofing in projects such as:
- Civil Construction: High-rise basement wall/floor joints, prefabricated concrete component seams, retaining wall expansion joints, lift shaft waterproofing.
- Municipal Engineering: Underground pipe trench joints, rainwater regulation tanks, subway auxiliary structure seams, sidewalk expansion joints.
- Water Conservancy & Environmental Protection: Small-to-medium reservoirs, sewage treatment pool circumferential seams, swimming pool wall joints, farmland water conservancy pond seams.
2.3 Shelf Advantages (For Procurement Decision-Making)
(1) Cost-Effective
- The 250mm width reduces material waste by 20% compared to 300mm wide models; 30-year service life cuts total cost by 45% vs. frequent replacement of ordinary sealants.
- Customizable roll lengths (10m+ short rolls available) fit small-batch project needs, avoiding inventory pressure for buyers.
(2) After-Sales Guarantee
- Quality Warranty: 5-year warranty for material defects (uneven thickness, reduced elasticity)—non-human damage eligible for free replacement.
- Technical Support: Free provision of electronic installation videos, welding operation guides, and cross-section drawings; 24-hour online consultation for on-site construction issues.
(3) Supply Reliability
- Packaged in moisture-proof polyethylene film to prevent sun/rain damage during transportation. Monthly supply capacity reaches 100,000 meters, 5-7 day delivery lead time—ensures timely project supply.
Note: Custom colors (black/yellow/blue) and steel-edge composite versions are available. Contact customer service to obtain third-party test reports, samples, or bulk quotation discounts!
