Bentonite Waterstop Bar Water Swelling Waterstop Strip for Tunnel Basement

Bentonite Waterstop Bar Water Swelling Waterstop Strip for Tunnel Basement. Rapid expansion when encountering water, automatically fill concrete gaps, block leakage channels for long-term waterproofing. Solve poor fitting, micro water seepage and material failure problems. Realize self-healing plugging for better sealing effect. High and uniform expansion rate, excellent aging and erosion resistance, good compatibility with concrete, firm bonding without falling off. Suitable for waterproofing of construction joints and post-casting belts in basements, tunnels, water conservancy projects, reduce engineering leakage rate. Faster expansion, denser filling and better impermeability than ordinary waterstop strips, easy construction with higher cost performance.
