Solving your Infrastructure issues
At EagleLIFT, our goal is to solve your infrastructure issues, and not just offer short-term repairs. That means inspecting the problem and determining its root cause before quickly taking action. We then inject a high-density structural polyurethane through the impacted structure and into base soils, where it quickly moves throughout the aggregate and expands, filling voids and compacting grounds before curing into a solidified support system.
A variety of factors contribute to infrastructure degradation. Our innovative polyurethane injection process is ideal for use on public works and infrastructure assets impacted by the following:
- Soil settlement
- Soil compaction
We specialize in the rehabilitation of the following infrastructure types:
Culvert Rehabilitation Services
Culverts are subjected to deterioration through weathering and erosion over the years. As your culvert rehabilitation depends on the type of deterioration and root cause of the problem, we will perform a site-specific analysis of the area and provide you with the best possible solution. With reliable soil compaction and densification solutions, we can strengthen weak or loose soil strata, level concrete, and restore load-bearing capacity without damaging assets or the environment. Our infrastructure rehabilitation services are ideal for public works managers, engineers, municipalities, and state agencies. We minimize downtime, maximize budgets, and extend the infrastructure lifecycle with innovative no-dig solutions. Give us a call to learn more about our foundation culvert replacement services.
Polyurethane Injection Process
Polyurethane grout is a hydro-insensitive plural component grout that expands as a consequence of a chemical reaction. The two-part grout sets and alters the physical properties of a geologic mass, traveling through a soil profile initially by permeation and then by densification due to an expansive exothermic reaction. The polyurethane grout binds as a closed-cell formation and has expansive qualities of 15 to 22 times the initial volume. The advantage of polyurethane is that it is not as sensitive as permeation grout in regards to soil conditions. It is not dependent on moisture and is still effective in highly saturated environments. Additionally, polyurethane’s cure time is fast, setting up to 90% density in 15 minutes whereas permeation grout requires approximately 24 hours in optimal situations.
Our polyurethane injection process for infrastructure rehabilitation utilizes a fully self-contained injection rig with a 60kW diesel generator set, a 5hp 23 CFM air compressor, and a refrigerated dryer/regulation system. The systems use double diaphragm feed pumps and an impingement-style gun. The ½” diameter steel tubing is driven down to discrete injection elevations. The multiple injection elevations result in stacked spheres of polymer with the tubing being sacrificial upon completion of the injection. The tubing can be angled for void fill or centerline foundation repairs. Due to the highly expansive qualities of the two-part chemical grout, monitoring for movement is required using a laser level.
