BENTOGROUT®, manufactured by CETCO® and distributed by Engineered Site Products is a high-solids grout consisting of a proprietary blend of bentonite and polymers formulated for sealing water leaks in existing below-grade structures. Its unique blend of bentonite and polymers expands to form a barrier across the structure’s surface, sealing small cracks in the concrete while filling voids in the adjacent soil. Applications include:

• Foundation walls
• Underslab
• Tunnels
• Manholes
• Sheet piling interlocks
• Utility vaults
• New construction (atypical conditions)

Durable, self-sealing, and good for the planet

Even as the structure settles, BENTOGROUT®’s bentonite component maintains its ability to flex, absorb water, and self-seal, expanding to seal cracks and block any gaps. What’s more, a BENTOGROUT® barrier doesn’t shrink or dry out, and typical freeze/thaw cycling has no effect on its performance. BENTOGROUT® consists primarily of the naturally occurring volcanic mineral bentonite, so it will not only last as long as the structure it’s protecting, but it’s also environmentally friendly.
