Product Overview
This PVC Waterstop is a flexible waterproofing sealant strip manufactured from Polyvinyl Chloride (PVC) material, specifically engineered to control water seepage through joints in concrete structures. Its core function is to be embedded during concrete pouring, forming a continuous water-resistant barrier to manage moisture at critical points such as construction joints, expansion joints, and cold joints. This product plays a significant role in various civil engineering and construction projects and is commonly used in underground parking garages, foundation slabs, tunnels, subway stations, reservoirs, wastewater treatment plants, and bridge abutments—projects where water resistance is a key consideration. Its design accommodates minor structural movements caused by loading, temperature variations, or settlement while aiming to maintain sealing integrity.
Key Features & Advantages
The use of industrial-grade PVC raw materials provides the product with good flexibility, resistance to chemical corrosion, and aging characteristics. Its composition supports the stability of physical properties over extended service periods.
The unique cross-sectional profile works to extend the water penetration path. When water pressure acts on the joint, this design can promote tighter adhesion between the material and the concrete, thereby enhancing water-blocking performance. Its flexibility allows it to accommodate joint movement.
The product is soft and pliable, making it easy to bend, cut, and splice on-site to fit complex joint layouts. It can be securely fastened to reinforcement bars at predetermined locations using wire or specialized clamps, preventing displacement during concrete pouring.
As a non-metallic material, it is not prone to rust. Compared to some alternative waterproofing methods, PVC Waterstop generally offers a cost-efficient sealing solution, and its installation process is relatively straightforward in terms of technical skill required.
Technical Specifications & Installation Reference
We can supply a variety of specifications of PVC waterstop to meet the design requirements of different engineering projects. Common products include models with varying widths, thicknesses, and physical performance indicators to adapt to a wide range of application scenarios. The specific technical parameters of the product (such as tensile strength, elongation, hardness, and chemical resistance) all comply with relevant industry standards. To inquire about exact specification models, technical data sheets, or to obtain samples, please contact our sales or technical support team.
To support the intended waterproofing outcome, the following general site practice points are recommended: clean the joint area before installation; ensure the waterstop is centrally positioned within the concrete pour; carefully make splices, suggesting reliable connection methods (e.g., heat fusion welding) to ensure continuity and strength at joints; and exercise care during concrete vibration to avoid creating voids around the waterstop.
