Concrete Leveling In Oak Park, Illinois

The Real Seal offers concrete leveling services in Oak Park, Illinois using polyjacking to raise and level sinking concrete slabs, patios, pathways, and driveways. Expanding polyurethane foam is used in this method. Compared to other alternatives like mudjacking, it is a non-toxic concrete leveling method.

Why Does Concrete Settle?

Many factors cause concrete to settle, including poor drainage, compaction, site conditions, and tree roots. The most common cause of concrete settling is when water from gutters and rain washes dirt out from under your sidewalk or driveway. This creates pockets or voids underneath your concrete causing it to settle.

Another factor that causes concrete settlement is clay-rich soil that expands and retracts according to its moisture content. This clay-rich soil expands when it is saturated with water and shrinks when it is dried out. This change in the moisture content creates unstable soil, which leads the concrete to move and sink.

Why Does Concrete Settle

Concrete Leveling Using Polyjacking

Concrete should be supported by soil that is as stable and strong as the concrete itself. Otherwise, it might not be able to support the weight. If the problem is weak soil, the slab cannot be replaced.

Benefits of Polyjacking​

Quick Action

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


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


The foam is made up of lightweight polyurethane in contrast to the heavy-weight materials used in other techniques.

Environmentally Friendly

The foam used for polyjacking does not let any dangerous substances seep into the ground and fills up all the voids in the soil.


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 therefore, not easily weakened by water.
