Our polyurethane soil stabilization technique is a process where we inject a high-density polyurethane adjacent to the impacted infrastructure.  Once injected, the polyurethane moves throughout the voids similar to how water finds the path of least resistance.  After a few short minutes, the polyurethane begins to react and expand throughout the voids, densifying adjacent soils and filling the compromised joints with polyurethane.
The polyurethane is a hydro-insensitive formula, meaning it pushes away any present water and prevents future washout or infiltration by creating a water tight seal.

Here are some of the benefits to repairing Inflow and Infiltration with polyurethane:

• Fast and Minimally Invasive – it requires no excavation and can be completed in hours.
• Minimal Disruption to Traffic – Repairs can be performed from within or above the structure, and can take place during non-peak hours.
• Cost-Effective – with minimal downtime, fast repair, and lower man-hour costs, polyurethane inflow and infiltration repair is very cost-effective.
• Fill Voids and Restore Soil Support – Polyurethane injection fills voids and restores load support back into the soils with one application.
• Lift, Level, and Realign – Level structures such as roadways, outfalls, sidewalks, and rail lines while simultaneously sealing the subgrade infrastructure.
