Reliable Grouting Solutions for Diverse Soil Types

US Grout’s Ultrafine cementitious grouts are used to improve the soil characteristics and function of many challenging sites while being economical, effective, enduring, and non-hazardous. Once injected into the soil, the cement grout works for centuries, stabilizing weak soil structures, imparting load-bearing compressive strength, and sealing against leachate within most soil types.

Century-Long Durability of Cementitious Grouts

Unique among all cementitious grouts produced worldwide, US Grout’s products are made with similar pumice-based pozzolan chemistry the Romans used over 2,000 years ago. As proven by the Pantheon and many ancient Roman structures standing strong after two millennia, US Grout’s patented pumice-pozzolan-based cement provides unparalleled longevity. Developed by the U.S. Department of Energy for the Waste Isolation Pilot Plant (WIPP), US Grout produces Ultrafine products that are equal to or superior to any cement grout available in the marketplace.

Ultrafine Grouts for Stabilizing Soil and Sealing Microfractures

The key to effective soil permeation is particle size and rheology, rather than viscosity. Particle size and rheology determine a grout’s ability to penetrate and properly disperse in soil. This image shows salt rock from a waste isolation pilot plant with visible cracks and fractures. US Grout’s Ultrafine grouts feature significantly smaller particle sizes compared to conventional cement, allowing for superior soil permeation even with a lower water-to-cement ratio, while achieving high compressive strengths.

Conventional Grouting Practices, Unconventional Grout Solutions

US Grout products are re-formulated for challenging grouting situations and designed for placement using conventional grout practices and equipment. US Grout’s cement grouts offer a generous injectability window of over two hours, are easy to mix properly, and are safe to use. Some solutions are listed below:

  • Stabilize and Strengthen Soil and Sand:
    Enhance soil integrity for construction and environmental projects.
  • Seal Seepage in Mines, Dams, and Tunnels:
    Prevent water intrusion and improve structural stability.
  • Form Low-Permeability Grout Curtains:
    Create effective barriers for water control and containment.
  • Fortify Waste Containment:
