Cetco Bentogrout Remedial Waterproofing Injection Grout 50lb Bag

BENTOGROUT is a high-solids grout consisting of a proprietary blend of bentonite and polymers formulated for sealing water leaks in existing below-grade structures. BENTOGROUT is pumped in a fluid state adjacent to the exterior of the structure where it sets into a gelatinous state forming a waterproofing barrier. BENTOGROUT can be used to seal leaks in concrete, masonry block, brick, and stone foundations.

Installation is fast and easy. Simply mix BENTOGROUT with water and pump it adjacent to the exterior of the building. There it solidifies and expands slightly to form a waterproofing barrier. It can be pumped from above-grade outside the structure without excavating or from the interior of the structure through drilled holes in the walls or slabs. Limited jobsite space is required for injection.

Unlike many remedial waterproofing products that are applied as a surface treatment to the interior of the foundation, BENTOGROUT is applied to the exterior of the building where it stops the water before it can penetrate the structure and further corrode the reinforcing steel. The thick BENTOGROUT barrier covers the exterior surface of the structure filling voids in the adjacent soil and bridging over small cracks in the concrete. Also, BENTOGROUT has the ability to self-seal if the structure settles and therefore its performance is not limited by future hairline cracking in the concrete. BENTOGROUT does not shrink or dry out in sub-surface soil formations and is not affected by freeze/thaw cycling. It remains flexible, maintains a putty-like consistency over time, and retains a swell potential to seal itself off. And since BENTOGROUT primarily consists of natural minerals it is friendly to the environment and will last the life of the structure.
