Our concrete leveling services in Naperville, Illinois, include leveling concrete slabs, patios, driveways, and even walkways. Expanding polyurethane foam is used for the polyjacking procedure. It offers a quicker, more dependable, and non-toxic alternative to mudjacking for effectively leveling concrete.
Why Does Concrete Settle?
Multiple factors, including inadequate compaction, bad site conditions, poor drainage, and tree roots, can cause concrete to settle. The biggest cause of this problem is when rain or gutter water washes away dirt from your driveway or sidewalk. As a result, the concrete is left with voids or pockets underneath it, which consequently causes it to settle.
Another factor is clay-rich soil, which varies in size as per the soil moisture levels. The soil expands when it gets water-saturated and shrinks as it dries out. As a result, the soil is rendered unstable because of the frequent changes in moisture, causing the concrete to shift and sink.

Concrete Leveling Using Polyjacking
The concrete should be supported by a solid foundation of soil. The concrete slab cannot be replaced if the earth beneath it is unstable. Polyjacking is the perfect answer to this problem.
Expert Concrete Leveling Services in Naperville, IL
At The Real Seal Basement Waterproofing and Foundation Repair, we offer professional polyjacking to fix uneven concrete throughout Naperville and surrounding areas. This modern solution lifts and stabilizes sinking concrete without the mess and cost of replacement. Polyjacking uses expanding foam to level concrete, giving you a smooth, safe surface that will last for years.
Here’s how our polyjacking process works to deliver remarkable results:
Drill Holes
We start by drilling small, dime-sized holes in your concrete slab. These tiny access points are placed carefully to allow the foam to reach exactly where it’s needed underneath your concrete. Unlike older methods, these tiny holes (less than 1 inch) will not damage the appearance of your surface.
Foam Injection
Next, we place injection ports into these small holes. Our professionals use a specialized foam gun to inject liquid polyurethane slowly beneath your concrete slab. This material flows into all the empty spaces under your concrete, preparing for the lifting phase.
Lift and Fill
As the polyurethane begins to expand, it creates gentle pressure that raises your concrete slab. The foam grows up to 50 times its original size, completely filling the voids and elevating your concrete to the desired height. Our technicians monitor this process closely, ensuring your concrete reaches precisely the right level. Once lifting is complete, we fill the small injection holes using a matching concrete mixture so that the repair points virtually disappear from view.
Clean Up
After your concrete is level, we remove excess material and clean up the entire work area thoroughly, leaving your property tidy and clean. When we finish, you’ll have level concrete with barely any sign that repairs were ever needed.
Benefits of Polyjacking
Fast Acting
After a short 15-minute injection, you can readily walk on the concrete slab. The slab can successfully sustain vehicular traffic too.
Minimally-Invasive
Polyjacking the concrete slabs is not at all invasive for homeowners, as it does not involve any major excavation or digging.
Lightweight
The foam is made up of lightweight polyurethane. As opposed to other market techniques like mudjacking, which uses heavy materials, polyjacking does not cause soil settlement.
Environmentally Friendly
The foam used for polyjacking fills in all the solid voids and does not leak making it impossible for harmful substances to seep in.
Cost-Effective
Property owners can save up to half of the usual concrete slab replacement costs if they choose concrete leveling by polyjacking.
Waterproof
Polyurethane foam is waterproof which means it is not weakened by constant exposure to water.
