Product Overview

1. Core Features

Material Performance: The product adopts high-quality PVC composite material, which has excellent corrosion resistance and can resist the erosion of common chemical media in sewage and underground environments . It maintains good elasticity in the temperature range of -35℃ to 60℃, with no cracking in low-temperature bending and no brittleness in high-temperature environment . The water absorption rate is ≤0.5%, ensuring stable performance in humid environments for a long time .

Structural Design: The 320mm ultra-wide design fully covers the large-size construction joints and deformation seams, and the surface is designed with anti-skid convex lines to increase the bonding force with concrete and avoid displacement during pouring . The cross-section adopts a "double-wing + middle rib" structure: the middle rib enhances the longitudinal tensile deformation capacity, and the extended wings improve the contact area with concrete, effectively blocking the seepage channel . The thickness is 6-8mm (customizable), which meets the bearing requirements of medium and high water pressure environments .

Performance Parameters: The tensile strength reaches ≥10MPa, the elongation at break is ≥250%, and the Shore A hardness is 65±5, which fully complies with the requirements of GB/T 18173.2-2014 Polymer Waterproof Materials - Part 2: Waterstops . After 72 hours of hot air aging test, the tensile strength retention rate is ≥80%, and the aging resistance is superior . The unit weight is about 2.0-2.5kg/m, which balances structural stability and construction convenience .

2. Application Scenarios

It is especially suitable for engineering projects with wide joints and high waterproof requirements, including: large-scale reservoir dams and spillway structures , underground comprehensive 管廊 deformation joints , subway station platform floor expansion joints , municipal sewage treatment tank circumferential seams , and high-rise building basement outer wall construction joints . It performs well in environments with long-term water pressure, alternating dry and wet conditions, or mild chemical erosion .

3. Installation and Advantages

Efficient Construction: It can be fixed by steel bar clamping or template pressing, without special tools . The material can be cut arbitrarily according to the joint length, and the overlap joint can be bonded with special PVC adhesive to ensure the integrity of the waterproof system . It is highly compatible with the concrete pouring process, which helps to shorten the construction period .

Cost-Effective Durability: The product has strong resistance to microbial erosion and is insoluble in water and common oils . Under normal use conditions, the service life can reach more than 30 years, which significantly reduces the later maintenance and repair costs of the project . Compared with rubber waterstop，it has higher cost performance and is more suitable for large-area engineering applications .

Quality Assurance: Each batch of products has passed the third-party detection of tensile strength, low-temperature flexibility and aging resistance, and meets the acceptance standards of GB 50208-2022 Code for Acceptance of Construction Quality of Building Waterproofing Engineering .
