Concrete leveling in Addison involves lifting and leveling sinking concrete slabs, patios, sidewalks, or driveways using expanding polyurethane foam. It’s known as polyjacking, and it’s non-toxic, faster, and stronger than other concrete leveling solutions like mudjacking.

Why Does Concrete Settle?

Poor drainage, bad site conditions, and unwanted tree roots are some of the reasons why concrete may settle. The most common reason is when rainwater or water from your gutters washes away dirt from under the sidewalk or driveway. This creates a void under the concrete surface, which causes it to settle.

Another reason why concrete may settle is due to clay-rich soil. The soil expands and retracts as per the amount of moisture in it. When the soil is saturated with water, it expands. Then, when the soil dries, it shrinks. This instability in the soil causes the concrete to move and settle.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

Experts suggest the soil under the concrete must be as strong as the concrete itself. Otherwise, it can’t support the weight. If the soil remains weak, even replacing the slab won’t fix anything. Therefore, using polyjacking is an ideal solution.

Benefits of Polyjacking​

Fast Acting

15 minutes after injection, you can walk over the concrete slab. It will also be able to support vehicular traffic.


The whole polyjacking process doesn’t require any excavation.


The lightweight foam doesn’t contribute to further soil settlement, unlike with other processes like mudjacking, which involve heavy materials.

Environmentally Friendly

Polyurethane foam doesn’t react with soil or moisture. Moreover, it doesn’t add any harmful chemicals to the ground.


With polyjacking, you can save up to 50% of the total cost of traditional concrete slab replacement.


Once the process is done, the polyurethane foam won’t wash away or get affected by water.

What Is The Process Of Polyjacking Concrete Leveling?

The process involves some important  steps:  

Concrete Leveling

Step 1

Dime-sized holes are drilled into the sunken concrete areas.

Concrete Leveling

Step 2

Polyurethane foam is injected through the holes beneath the concrete.

Concrete Leveling

Step 3

The foam underneath the concrete expands, lifting the slab.

The polyurethane foam we use in polyjacking is nonorganic and doesn’t erode or decompose over time. So, the polyjacking process is a long-lasting and useful solution for sinking concrete.
