Concrete leveling in Bolingbrook involves lifting and leveling sinking concrete slabs, decks, sidewalks, and driveways with polyjacking, in which polyurethane foam is used. It’s a non-toxic method, faster, and stronger than other concrete leveling solutions like mudjacking.

Why Does Concrete Settle?

Concrete may settle for multiple reasons like poor drainage, low-quality compaction, damaged site conditions, tree roots, and more. The most common reason is when water from gutters or rainwater removes dirt from concrete surfaces like sidewalks or driveways. It creates voids or pockets into the concrete, which causes it to settle.

Concrete may also settle if there is clay-rich soil. When the soil is saturated with water, it expands. Then, when the soil dries, it contracts. Thus, the soil remains unstable, which causes concrete to move and sink.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

If the soil underneath the concrete is not strong enough, it can’t support the weight. Weak soil leads to crucial problems that can never be fixed by replacing only the slab. The polyjacking process is an ideal solution for that. 

Benefits of Polyjacking​

Fast Acting

Within 15 minutes of injecting the foam, your concrete slab will be ready to use. You can walk on it. It will also be able to support vehicular traffic.


The polyjacking process doesn’t need any excavation. Hence, it ensures no mess around your concrete.


The foam used in the process is lightweight. It doesn’t contribute to future soil settlement, unlike the heavy ingredients used in solutions like mudjacking.

Environmentally Friendly

The inert polyurethane foam neither reacts with soil or moisture nor seeps harmful chemicals into the ground.


The polyjacking process saves up to 50% of the total cost of traditional concrete slab replacement methods.


Once the process is done, the polyurethane foam doesn’t wash away.

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.
