Superstop Bentonite Waterstop

Superstop is a composite waterstop system incorporating granular, expandable bentonite that’s layered on one edge with a pressure-sensitive adhesive. It is designed for sealing cold joints in concrete and preventing water migration through construction joints below grade.

• Effective waterproofing under proper compaction to prevent water migration
• For vertical installations, use an approved primer
• One edge is coated with pressure sensitive adhesive for easy placement
• Saltwater-grade version available for use in brackish water environments
• No primer required for horizontal installations

• Service Temperature Range: –40 °F to 230 °F (–40 °C to +100 °C)
• Application (Installation) Temperature Range: 0 °F to 120 °F (–17.8 °C to +110 °C)
• Specific Gravity (ASTM D71): 1.75
• Tear Strength (ASTM D751): 70 lb (≈ 31.7 kg)
• Color: Gray
• Softening Point (ASTM D30): 212 °F (100 °C)
