Concrete leveling in Evanston is done by lifting and leveling concrete slabs, patios, driveways, or sidewalks. This process is called polyjacking, in which expanding polyurethane foam is used. It’s a non-toxic concrete leveling method that is faster and more robust than other solutions like mudjacking.

Why Does Concrete Settle?

Concrete can settle for several reasons, such as insufficient compaction, poor drainage, unsuitable site conditions, and tree roots. The most prevalent cause of concrete sinking is rain and gutter water clearing out debris from beneath your driveway or sidewalk. Your concrete can move because of voids or pockets that develop beneath it.

The presence of clay-rich soil, which alters in size in response to moisture levels, is another factor. When this soil gets moist, it expands, and when it dries out, it contracts. The soil becomes unstable due to the change in moisture content, which causes the concrete to shift and sink.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

Soil that is equally solid and durable as the concrete itself must support it to improve durability. If that does not happen, it might be unable to carry the weight. The slab cannot be replaced if the problem is unstable soil.

Benefits of Polyjacking​

Quick Action

Just 15 minutes after the injection you can easily walk over the concrete slab. The slab is sturdy enough to accommodate vehicular traffic as well.


The process can be minimally invasive for owners as it does not involve any major excavation or digging.


The foam is made up of lightweight polyurethane. In comparison to other leveling techniques like mudjacking, which uses heavy materials.


Polyurethane foam fills the voids in soil and saves it from any kind of poisoning.


Homeowners can easily save up to 50% of the traditional concrete slab replacement costs if they go for concrete leveling by polyjacking.


Polyurethane foam is waterproof and cannot be weakened by water at all.

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.
