Concrete Lifting, Concrete Jacking or Concrete Leveling is the process of using polyurethane foam to raise and level out concrete. Polyurethane foam is also used for concrete void filling and joint/slab stabilization. The concrete lifting process starts by drilling a hole into the concrete. The polyurethane foam is then injected into the hole expanding and slowly raising the concrete. Once the concrete has been leveled, a small patch is then placed over the injection site. This method is used because it reduces rework due to erosion and does not over burden the sub base. The delayed expansion of the polyurethane foam allows it to travel further and prevents over raising of the concrete slab. Concrete Lifting can be used for residential and commercial projects.
- For Department of Transportation, the application process is quick allowing for minimal lane closures and traffic disruptions.
- The injection site is less obtrusive. It leaves a small hole which is patched in minutes.
- The process of lifting, raising or jacking concrete is inexpensive and quick compared to replacing concrete.
- The polyurethane foam will never lose density and never sink due to its lightweight material.
- It is a green application. The foam is made from recyclable materials so it does not contaminate soil.
- Lifts building structures and stabilizes soil.
