Concrete leveling in Elmhurst employs a technique called polyjacking to raise and level sinking concrete slabs, patios, pathways, and driveways. Polyurethane foam that expands is used in this method. In comparison to other alternatives like mudjacking, it is a non-toxic concrete leveling method that operates more swiftly and efficiently.

Why Does Concrete Settle?

Numerous factors, including inadequate compaction, poor drainage, unfavorable site conditions, and tree roots, can cause concrete to settle. Concrete settling is most frequently caused by rainwater and gutter water washing debris out from under your driveway or sidewalk. This causes voids to form under your slab, sinking the concrete.

Another aspect is clay-rich soil, which changes in size in reaction to moisture content. This soil expands when it is wet, and it contracts when it is dry. The change in moisture content makes the earth unstable, which causes the concrete to move and sink.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

Concrete must be supported by soil as stable and strong as the concrete itself. Otherwise, it might not be able to support the weight. If the issue is the weak soil even if the slab is replaced, the problem will repeat itself over time.

Benefits of Polyjacking​

Quick Action

Just 15 minutes after the injection, you can walk, park, and drive over the slab without any damage.


The technique is minimally invasive for owners as it does not involve any major excavation or digging.


The foam is composed of lightweight polyurethane in comparison to other techniques like mudjacking, which uses heavy materials.


The foam used for polyjacking does not seep dangerous substances into the ground and therefore, prevents soil poisoning.


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


Polyurethane foam is waterproof and is not affected by water once cured.

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.
