BENTOSEAL is trowel-grade, sodium bentonite/butyl-rubber based sealant designed for a variety of surface preparation and waterproof detailing work with Volclay Panels, Swelltite and Voltex waterproofing membranes. Being bentonite based, BENTOSEAL swells upon contact with water to seal against water intrusion. With the consistency of thick grease, BENTOSEAL is easy to apply and bonds to most substrate materials.

APPLICATIONS

BENTOSEAL is an below-grade waterproofing accessory product designed for the following uses:

• Fillet material at horizontal and vertical inside corners
• Flashing material around drains, mechanical and electrical penetrations, curbs and parapets
• Sealing material at waterproofing terminations
• Repair material for small concrete substrate surface defects prior to waterproofing membrane installation
• Trowel-grade waterproofing for extremely irregular substrate surfaces.

BENTOSEAL is formulated for use on structural concrete, masonry, wood and most metal surfaces. Do not use BENTOSEAL on extruded polystyrene (EPS) concrete forming systems. Use in applications with proper confinement only. Backfill soils should be compacted to a 85% Modified Proctor density. BENTOSEAL is not an expansion joint sealant.
