PVC WATERSTOPPER WO - 150: Ideal for Durable Waterproof Solutions

2.1 Core Features

2.1.1 High-Quality Materials and Stable Performance

• Mechanical Strength: Tensile strength reaches 15.7N/mm² (far exceeding the industry standard of 12N/mm²), elongation at break is ≥300%, and tear strength is ≥40kN/m. It can withstand concrete vibration and steel bar collision without damage during construction.
• Environmental Adaptability: The brittle temperature is ≤-35℃, and there is no softening or deformation at high temperatures, making it suitable for cold climates in the north and high-temperature climates in the south. The water absorption rate is ≤0.5%, and it can be soaked in sewage, seawater, and other environments for a long time, with excellent acid and alkali (pH 3-10) corrosion resistance.
• Durability: After 70℃×72h thermal aging test, the strength retention rate is ≥85%, and the service life can reach more than 20 years under normal use conditions, without frequent replacement and maintenance.

2.1.2 Wavy-Optimized Structure and Precise Dimensions

• Structural Advantages: The central wavy elastic core can absorb horizontal and vertical displacement simultaneously, with 30% higher displacement adaptability than ordinary flat waterstops, making it particularly suitable for dynamic waterproof needs of small and medium-sized expansion joints. The diamond-shaped ribs on the flange surface have a height of ≥8mm, which increases the bonding force with concrete by 40% compared to smooth surfaces, eliminating the risk of interlayer leakage.
• Dimensional Specifications: 150mm width (tolerance ±4.5mm), standard thickness 4.0±0.5mm (5-8mm customizable), each roll length 20-25m. The packaging uses moisture-proof polyethylene film to prevent performance degradation caused by sun exposure and rain during transportation.

2.1.3 Compliance and Construction Compatibility

• Complies with U.S. Army Corps of Engineers CRD-C 572-74 standard and NSF/ANSI 61 drinking water contact certification, and can be used in scenarios with high hygiene requirements such as domestic water tanks.
• Supports hot welding connection (welding temperature 140-160℃), and the joint strength is consistent with the main body. It can be fixed to steel bars with binding wires through pre-punched holes or positioned with tie rods and templates, with construction efficiency 25% higher than traditional waterstops.

2.2 Application Scenarios

• Civil Construction: Construction joints of basement floors, joints between bathrooms and floors, and anti-seepage of small water storage tanks.
• Municipal Engineering: Small rainwater wells, branch joints of underground pipe corridors, and expansion joints of highway culverts.
• Special Facilities: Small sedimentation tanks in sewage treatment plants, joints of swimming pool walls, and foundation joints of small industrial storage tanks.

2.3 Core Advantages for Shelving

2.3.1 Strong Scene Adaptability

2.3.2 Low Construction Threshold

2.3.3 Comprehensive After-Sales Guarantee

• Provides a 5-year material quality guarantee, covering quality issues such as uneven thickness and reduced elasticity. Free replacement is available for non-human damage.
• Free electronic installation videos and size selection guides are provided, and 24-hour online technical consultation is supported to help buyers quickly implement projects.
