Chemical Grouting for Soil Stabilization

Soil instability can cause significant structural problems during and after the building process. Structures built on sand, soft ground, fractious rock, and other terrain types not naturally suited to tolerate heavy loads can suffer from cracking, sinking, and structural integrity deterioration. EagleLIFT offers chemical soil grouting services for soil stabilization throughout all of California, Arizona, and Nevada

What is Chemical Grouting?

Chemical grouting for soil stabilization is a form of permeation grouting where chemical grout fluid into base soils produces stone-like masses that are capable of carrying loads of the structures above. Chemical grouting has many advantages over other grouting methods, such as cement-based ones. Cementitious grouts are heavy, porous, dry unevenly, crack easier, wear faster, and have minimal flex.


Chemical grouting helps to:

  • Improves soil strength
  • Bolters soil rigidity
  • Reduces soil vibration
  • Controls water flow
  • Limits ground movement


Our chemical grouting process utilizes high-density structural polyurethane, which is injected into base soils through 3/4” metal rods. The polyurethane quickly travels throughout the aggregate and enlarges, which acts to:

  • Bind soil media together
  • Fill gaps
  • Reduce permeability
  • Stop soil compression
  • Increase soil strength
  • Mitigate inflow, infiltration, and leakage of water


Strengthen loose soil strata with chemical grouting from EagleLIFT, a leading full-service ground-engineering solutions firm. Our chemical grouting process can stabilize base soils successfully, quickly, and at an affordable price with little to zero interference with day-to-day activities at the impacted structure or job site.

Our chemical grouting is fast-acting, nondestructive, and environmentally safe. The polymer is neither chemically nor biologically reactive and will not decompose. Additional characteristics include:

  • Expands up to 25 times its initial volume
  • Unaffected by standing water
  • Increases a soil’s weight-bearing capability
  • Displaces trapped water
  • Not compromised by wet conditions during or after installation
  • Seals leaks and misaligned joints
  • Not impacted by contamination, microbial corrosion, and or high acid levels

Need Chemical Grouting?


As a commercial chemical grouting contractor, our highly trained technicians can easily inject chemical grout into spaces with limited access or where no structural connection to the foundation being underpinned is required. After injection, the soil will become more stable in a few minutes. The polyurethane material will cure into a strong, durable, and long-lasting replacement base material. This process allows for minimal to zero work area shutdowns, no soil excavation, and crews can work during off-peak, nighttime, or when employees are not on the floor.


Our chemical grouting process is ideal for a wide range of applications. Examples include:
