Power Jack uses the latest technology for raising compromised concrete and home foundations called Polyurethane Foam Injections. This involves drilling nickel-size injection holes into concrete foundation and filling the voids underneath with an earth-friendly polyurethane that lifts the settling concrete foundation. Our method was developed and is used as an alternative to concrete Pressure Grouting or Mudjacking. We utilize this non-destructive and extremely effective concrete leveling solution to keep cost and homeowner inconvenience to a minimum. Polyurethane Foam Injections are our least invasive process for foundation repair inside the home, with the smallest amount of damage to preserve existing floor coverings. Most repairs can be completed in just 1 day.
