Cementitious Grout Solutions

Cementitious Grout Solutions
Ultrafine

Unique among all cementitious grouts produced in the world today, US Grouts are made with the same pumice-based pozzolan the Romans used over 2000 years ago. As proven by the Pantheon and many ancient Roman structures standing strong after 2 millennia, US Grout’s patented pumice-pozzolan based cement provides unequaled longevity. Developed by the U.S. Department of Energy, the aptly named US Grout produces Ultrafine products equal or superior to any ultrafine grout available in the marketplace.

A Superior Grout

All products are sourced, refined, and produced in the United States. They are supplied and supported by industry recognized grouting expert Avanti International. US Grout products are the professional choice for those critical grouting applications where only a superior, high-performance grout will do.

  • US Grout products are ready to mix and pump without additional admixtures.
  • Customized blends are available.
  • Competitively priced; stable North American supply.
  • Stringent quality control and modern plant facilities ensure uniformity.
  • Expert technical support; international distribution network.
  • Ultrafine grout will penetrate smaller fractures and finer-grained soils.
  • Low internal cohesion means greater penetration and lower drilling costs.
  • Composed of non-hazardous materials.

Permeation Grouting

An extensive, large scale permeation test proved that US Grout Ultrafine can pass through, and completely grout, a silty sand with a hydraulic conductivity as low as 5 x 10-2 centimeters/second. The hydraulic conductivity of the grouted mass was reduced to 1 x 10-7 centimeters/second.

Particle Size Information

Particle size and internal cohesion, not viscosity, determine a grout’s ability to penetrate extremely small openings. Ninety percent of the particles in Ultrafine grout are smaller than 8 microns and average 3 microns.*

GROUT CHARACTERISTICS

 POZZOLANIC GROUTS ARE ENGINEERED FOR:
  • Wide range of water to cement ratios.
  • Little or no bleed at recommended water-to-grout ratios.
  • Two-plus hours of injectability.
  • Rheology and set time adjustable with various admixtures.
  • Enhanced strength and decreased permeability.
  • Volume stability, less than 0.1% linear shrinkage.
  • Water soluble lime and alkalinity are greatly reduced.
  • Extremely low hydraulic conductivity/permeability.
  • Brine tolerant; applications in and around salt water.
  • Resistance to chemical attack due to lower alkalinity and very low hydraulic conductivity.
  • A low heat of hydration resulting in higher resistance to thermal contraction cracking.
*These sizes were determined by the Micro Meretics Company, using their sedigraph.

The pozzolanic qualities of US Grout’s pumice-based cements are legendary. The Romans built an empire on pozzolanic (pumice) concrete structures that endure to this day – some 2000 years later. Now, enhanced by state-of-the-art refining and injection processes, that same pozzolanic chemistry fortifies a high-performance grout that is superior in performance and effectiveness. Naturally.
