What Is Permeation Grouting?
Permeation grouting or chemical soil grouting is a method of foundation underpinning that is often used in sandy soil conditions to help strengthen loose soil strata. During the permeation grouting process, a deep hole is drilled and immobile grout is injected into the soil using high-pressure equipment to fill cracks or other small defects in non-cohesive soils. Permeation grouting helps to:
- 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
successfully stabilize base soils
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
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:
- Future home construction
- Commercial foundations
- Residential foundations
- Multi-family dwellings
