Bentonite Waterstop

Bentonite waterstop is a water-stopping material made by mixing sodium bentonite, the main raw material, with fibers, elastomers, etc. It has a unique water-swelling property. After coming into contact with water, its volume can expand several times, filling gaps and forming a sealed water-stopping layer. This waterstop has good low-temperature resistance and anti-aging performance. It is easy to install without the need for complex tools and can bond tightly with concrete. It is suitable for waterproofing construction joints and post-cast strips in projects such as buildings and water conservancy facilities.
