Product Description
Superstop is a bentonite waterstop system designed for effective below-grade waterproofing. This composite material features granular bentonite with a pressure-sensitive adhesive on one edge, ensuring easy application and strong bonding. It prevents water infiltration through concrete cold joints, making it ideal for foundations and below-grade structures.
Key Benefits
- Enhanced Waterproofing: Effectively seals joints to block water migration through concrete cold joints below grade.
- Easy Installation: Can be installed without primer on horizontal surfaces; primer recommended for vertical use.
- Versatile Use: Saltwater-grade version available for marine and brackish water environments.
Best For
- Sealing cold joints in concrete
- Preventing water migration through construction joints below grade
