How Polyurethane Concrete Lifting Works

concrete, lifting, leveling, polyurethaneThere is no denying that cracks in your concrete can be a cause of trips and hazards. They can increase wear and tear on tires and make snow removal very difficult. It can look unsightly as well!

You can combat settled and sunken concrete by leveling it using polyurethane foam. The polyurethane concrete raising process is quick and efficient. Here’s how it works:

Before you level

There are a few things you need to consider and do before concrete leveling takes place. 

Get an estimate

The first thing to do would be to get an estimate. Once you schedule an estimate, a technician will come out to inspect your settled concrete. 

Schedule your concrete leveling

After receiving your estimate you can schedule your concrete leveling repair.

Day of Service

Unlike replacing your entire sidewalk or driveway, raising your concrete with polyurethane takes only 1-2 hours. The process is simple and mostly mess-free. 


  • Drilling – It begins with drilling a few ⅝” holes into the concrete slab that is being raised. One of the benefits of choosing polyurethane concrete raising over mudjacking is the size and the number of holes drilled into the cement. 
  • Filling – Using an injection gun and a tapered delivery port, polyurethane foam is pumped below the sunken concrete. The foam fills the gaps where soil under the slab has settled or washed away. 
  • Raising – Once the polyurethane foam is injected below the concrete, a chemical reaction occurs. It expands and raises the concrete
  • Cleanup – Once completed, the holes are filled in and all equipment is removed from site.


Using your concrete again

Once the concrete is raised to the desired height you need to allow 15 minutes for the polyurethane foam to cure. Once it has, you can walk and drive on the concrete slab once more.
