UNIQUE AMONG THE CEMENTITIOUS GROUTS produced in the world today, US Grout Ultrafine™ is strengthened and made exceptionally enduring with the same pumice-based pozzolan technology the Romans used in their concrete over 2000 years ago. Developed by the U.S. Department of Energy, US Grout Ultrafine™ products are typically superior in injectable performance and cured density to any cementitious grout available in the marketplace.

Stabilize Soils

US Grout Ultrafine are widely applicable to various soil types

It is particle size and rheology, not viscosity, that determines a grout’s ability to effectively penetrate and properly disperse in fine, dense soils. Designed for job-specific adaptability, US Grout Ultrafine VX, paired with USG-Super™ (a super p), can work soil-binding magic in a wide range of soil permeation and stabilization projects—even the fine-grained soils that defeat effective penetration by other grouts. Cementitious grouts are economical, enduring, and non-hazardous for improving the soil character and function of those geotechnical challenges. [ MORE ]

Seal Microfractures

Successfully sealing and reducing the transmissivity of a rock mass with a cementitious suspended-particle grout requires a carefully-tuned rheology (fluidity) centered around a maximum particle dimension that does not exceed one-third to one-half of the fracture aperture—the solid particles must be fine enough to stay suspended in the liquid even when squeezed into microfissures. US Grout Ultrafine has an average particle size of 3 microns in diameter and will penetrate fractures as small as 6 microns as deep as 3 meters. Standard OPC grouts can’t even come close. [ MORE ]

The Pozzolanic Charge

US Grouts are charged with a natural pozzolan to boost cured density, strength and longivity

Think of the pozzolanic reaction as a molecular reclaimation process: the pumice ignites a powerful reaction within the hydrated cement paste that captures and melds with trouble-makings, concrete-weakening Calcium Hydroxide (a by-product of the cement-water reaction), ultimately converting the bad CH into beneficial Calcium Silicate Hydrate (CSH is the binder in concrete). And that additional CSH binder does what you’d expect: it tightly welds the grout particles into a dense, enduring, virtually impermeable matrix. [ MORE ]

Breathe Easy

Our cementitious grouts are composed of non-hazardous components and are safe to handle and use. Our grouts are also Certified by NSF International as conforming to the requirements of NSF/ANSI Standard 61 – Drinking Water System Components – Health Effects.
