Concrete leveling in Elgin, Illinois involves lifting and leveling concrete slabs, sidewalks, patios, and driveways. We do this by polyjacking, a method in which polyurethane foam is used. The process is non-toxic, faster, as well as longer lasting, compared to other concrete leveling solutions.

Why Does Concrete Settle?

Concrete may settle due to various reasons like lack of proper drainage, poor compaction, tree roots, and adverse site conditions. The most common cause for concrete settlement is rainwater or water from the gutter washing out debris from underneath driveways or sidewalks. The voids or pockets created as a result can lead it to settle.

Another reason why concrete may settle is the contraction of clay-rich soil that expands due to changing moisture content. As a result, the soil also becomes unstable, causing the concrete to shift and sink further.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

The soil beneath the concrete of your home should be sturdy enough to hold its weight. Otherwise, it won’t be able to support the weight of the concrete, making it impossible to replace the slab.

Benefits of Polyjacking​

Fast Acting

After 15 minutes the foam is injected, you'll be able to walk over the concrete. It will also be strong enough to support vehicular traffic.


The process is minimally invasive as it does not involve any major excavation that may bother the homeowners.


The foam consists of lightweight polyurethane. In contrast to other leveling techniques like mudjacking that use heavy materials, leading to soil settlement in the future.

Environmentally Friendly

The foam used for polyjacking is not sensitive to moisture. Moreover, it stops dangerous substances from seeping into the ground.


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


Polyurethane foam is not easily affected by water after being settled. It is completely waterproof and durable.

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.
