Concrete leveling services by The Real Seal in Lake Forest, Illinois are used to raise and level concrete slabs, sidewalks, patios, and driveways. This technique involves polyjacking, a method in which polyurethane foam is used. The leveling process is non-toxic, fast, as well as long-lasting when compared to other concrete leveling solutions.
Why Does Concrete Settle?
Concrete can settle due to a variety of reasons such as lack of proper drainage, poor compaction, tree roots, and adverse site conditions. The most common cause that causes concrete settlement is rainwater or water from the gutter washing out soil from underneath your driveways or sidewalks. The voids or pockets created as a result can lead it to settle.
Another reason why concrete can settle is the shrinking of clay-rich soil that grows due to varying levels of moisture content. As a result, the ground becomes unstable, causing the concrete to shift and sink even more.
Concrete Leveling Using Polyjacking
The soil underneath a concrete surface must be strong enough to hold its weight. Otherwise, it will not be able to support the concrete structure, making it impossible to keep the slab from sinking. You must remember that if the problem is weak soil, the slab will sink again.

Poly Jacking Process
The polyjacking process includes the following steps:

Step 1: Dime-sized holes are drilled into sunken concrete surfaces.
Step 2: Polyurethane foam is injected into the holes.
Step 3: The foam beneath the concrete expands and lifts the slab.
Since the polyurethane foam is inorganic, it won’t decompose over time. Consequently, this technique provides a reliable solution for sinking concrete.
The Benefits of Polyjacking
Quick Action
Just 15 minutes after the foam is injected, you can easily walk over the concrete. It is strong enough to support heavy weights such as vehicular traffic.
Minimally invasive
The process creates the minimum inconveniences for owners as it does not involve any major excavation that may bother them.
Lightweight
The polyjacking foam is lightweight in contrast to other leveling techniques such as mudjacking which use heavy materials, which leads to future soil settlement.
Eco-friendly
The foam used for polyjacking does not easily react to moisture and does not leak which keeps harmful substances from seeping in.
Pocket-friendly
Owners can easily save up to half of the traditional concrete slab replacement costs if they opt for concrete leveling by polyjacking.
Waterproof
Polyurethane foam is not easily affected by water once it has settled successfully. It is completely waterproof and highly durable.
What Our Customers Are Saying
George, our technician, did an outstanding job with the repair. During the process, he discovered a 2x4 that had been bolted directly into the foundation wall—a possible cause of the cracking we were seeing. He explained how that kind of pressure can lead to long-term structural issues, which we never would have realized on our own. George not only fixed the problem, but also walked me through the repair process and what was being done to ensure the wall would be properly supported going forward.
Both Rob and George were professional, knowledgeable, and respectful throughout. It’s rare to find a company where both the inspection and the repair sides are this strong. I’d highly recommend Real Seal to anyone needing foundation repair or basement waterproofing. Their team brings both skill and great communication—exactly what you want for something as important as your home’s foundation.
If you have a crawlspace want to add square footage to your home (or have a nice new spot to wait out tornados), I highly recommend reaching out to Real Seal about a conversion.
