Reliable, durable, and customizable engineering rubber products and bridge components for infrastructure projects worldwide.
PVC Waterstop is a flexible waterproofing material manufactured from high-quality polyvinyl chloride (PVC) through an extrusion process. It is mainly installed in concrete construction joints, expansion joints, and settlement joints to prevent water penetration through concrete structures.With excellent elasticity, aging resistance, corrosion resistance, and tensile strength, PVC Waterstop can accommodate minor movements caused by temperature changes, concrete shrinkage, and structural settlement. Various profiles, sizes, and customized specifications are available according to different engineering requirements.PVC waterstops are widely used in concrete structures because they create a continuous waterproof barrier inside joints and improve the long-term durability of structures.

Product Features：
1. Excellent Waterproof Performance
The special ribbed profile design increases the water flow path and effectively prevents water leakage through concrete joints.
2. High Flexibility and Movement Accommodation
PVC material provides excellent flexibility to absorb minor structural movements caused by temperature changes, shrinkage, and settlement.
3. Strong Chemical Resistance
PVC Waterstop offers good resistance against water, acids, alkalis, and various chemical environments.
4. Long Service Life
Made from durable PVC compounds, the product maintains stable performance under long-term concrete embedding conditions.
5. Easy Installation and Welding
PVC Waterstop can be connected by heat welding on site and can be fabricated into corners, T-joints, and cross joints according to project requirements.
6. Customized Production Available
·Width customization
·Thickness customization
·Length customization
·Profile design customization
·Color customization

Installation Method：
1. Positioning
Install the PVC Waterstop according to the construction drawing and ensure the centerline aligns with the concrete joint.
2. Fixing
Secure the waterstop with steel wire, clamps, or special fixing devices to prevent displacement during concrete pouring.
3. Concrete Casting
Ensure the concrete around the waterstop is fully compacted without voids or honeycombs.
4. Joint Welding
Connect PVC Waterstop sections by heat welding to ensure continuous waterproof performance.
5. Inspection
Check the installed waterstop for damage, displacement, or improper connections before final acceptance.
