Residential Chemical Compaction Grouting

Residential Soil Densification & Compaction

Soil instability can cause significant structural problems during and after the building process. Homes built on sand, soft ground, fractious rock, & other terrain types not naturally suited to tolerate heavy loads can suffer from cracking, sinking & structural integrity deterioration.

successfully stabilize base soils 

Strengthen loose soil strata with chemical grouting from EagleLIFT, a leading full-service ground-engineering solutions firm. Often used in sandy soil conditions, soil grouting is a time-tested method of foundation underpinning. During the process, a deep hole is drilled, and immobile grout is injected into the soil using high-pressure equipment. Chemical and permeation grouting applications:

  • Act as a jack to elevate sinking foundation sections
  • Control soft ground settling under commercial & residential buildings
  • Control water flow in leaking structures
  • Prevent structural movement during excavation projects
  • Improve the stability of underlying rock structures

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.

Chemical grouting is the introduction and permeation of chemical grout fluid into base soils to produce stone-like masses that are capable of carrying loads of the structures above. Sometimes called permeation grouting, this process. Our chemical grouting process 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 flexibility.

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


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


EagleLIFT’s 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?


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:

With more than 25 years of experience using polyurethane for concrete foundation lifting, soil stabilization, and structure rehabilitation, EagleLIFT is the top injection process provider in California and Nevada. We have obtained a Class A license and can provide a range of soil stabilization, foundation and trenchless sewer repair engineering solutions to clients of all sizes. All projects our teams take on are expertly designed, and the soils they address and thoroughly studied.
