What Is Concrete Leveling?

The soil in Illinois is great for farming but, for homeowners? Not so much. The black, silty clay loam does not drain well and, as a result, it could cause a concrete driveway, patio, sidewalk, or other slab to sink.

The good news is, that The Real Seal Basement Waterproofing and Foundation Repair can bring your settled concrete slab back into place again. We use polyjacking, which is the industry standard for concrete leveling.

Concrete leveling, or more specifically, polyjacking, is the process of injecting polyurethane foam under the slab. As the foam rapidly expands, it pushes the slab up and into place.

Concrete Leveling in Schaumburg, Illinois

Does Concrete Leveling Work?

Concrete leveling has been used by thousands of people throughout Illinois, including in the Schaumburg area. It is used because it works and it works well.

As long as the concrete is not fully deteriorated (some cracks are fine), it can be lifted into place. When polyurethane foam is used, it will lift the concrete and hold it in place for decades. Any cracks will also be minimized and can easily be patched after the lift is finished.

When Do You Need Concrete Leveling?

There are some obvious reasons why you might need concrete leveling. For example, if you have a concrete slab that used to be level and now it is not. On the other hand, there are some not-so-obvious reasons why concrete leveling may be the option for you. Here are some reasons to consider:

Settled Concrete

If soil conditions or poor drainage have allowed your concrete to settle, then concrete leveling is an option to consider.

Damage is Minimal

Concrete does not bend, so if the soil gives way under it, the slab is likely to crack. This does not necessarily stop you from using polyjacking to level the slab. On the other hand, if the damage to the concrete is significant, other options can be considered.

Water Pooling

Concrete leveling can also be used, at times, to handle a problem where water is getting into the basement and pooling in the area. The Real Seal can let you know what can be done after our free inspection.

You Like Saving Money

Concrete leveling with polyurethane foam is much less expensive than replacing the slab. The cost for material is similar but with the breakup and removal of the old concrete, it will cost you extra money.

You Like Simple

If you want a simple process that can be done in a limited time with a limited impact on your lifestyle, call The Real Seal. We can come lift the slab with polyjacking and you can begin using it minutes after we are done.

Concrete Leveling Methods

You are not without options when it comes to concrete leveling. The process has evolved over the years and sometimes, older methods are still used by concrete leveling companies.

There are two primary methods of concrete leveling in use, mudjacking and polyjacking. The other option is to completely tear out the concrete and pour a new slab.

Mudjacking

Mudjacking is an outdated process that is still used by some concrete leveling companies. It involves drilling large holes in the concrete and pumping a slurry of dirt, sand, and cement below the slab. As the slurry is forced into the area, it fills any voids and pushes the slab into place.

Although mudjacking can raise the slab, it is also problematic in many ways. First, the mud is heavy, so if the soil is incompetent, it will result in further sinking. It also tends to need to be redone every 3-5 years and the cleanup process is extensive.

Polyjacking

Polyjacking is the preferred method of concrete lifting and leveling. This process uses small holes drilled into the concrete and tapered ports for injecting polyurethane liquid under the slab. The polyurethane will begin expanding quickly up to 50 times its original volume.

As the foam expands, it both compresses the soil and pushes against the bottom of the slab, forcing it into position. Polyurethane is non-toxic, so it won’t impact the environment and it will last for decades. That is why The Real Seal will only use polyjacking as a concrete leveling option because you deserve the best.

Poly Jacking Process

Polyjacking is a multi-step process performed by a skilled concrete leveling technician. The goal is to lift part of the slab back to its original height.

1. Drilling:

One or more 5/8″ holes will be drilled through the concrete slab. Tapered injection ports are then put in place.

2. Grinding:

If the slab cracked where it settled, it may be necessary to grind the concrete so the two pieces can move freely during the concrete leveling process.

3. Jacking:

In some cases, a sidewalk jack may be used to raise the slab prior to injecting the foam.

4. Inject:

An injection gun is used to force the polyurethane through the hole we drilled in the slab and into the voids underneath it.

5. Expand:

The foam expands quickly to fill the void and the pressure it puts on the underside of the slab lifts it. The technician must monitor the lift so as to not inject too much polyurethane and overshoot the target height.

6. Clean:

Polyurethane foam cleans up easily. We scrape the excess foam from the slab, fill the holes, and clean the area thoroughly. When we leave, you will have a level slab, ready to use.

The Benefits of Polyjacking

Our customers in Schaumburg can enjoy the benefits of polyjacking. Those benefits include the following:

Hole Size

Mudjacking uses a large hole that may be up to 2" in diameter. Polyjacking is done through a 5/8" hole drilled through the concrete.

Time

The polyjacking process does not require a lot of machinery and can be done quickly. After the concrete leveling is finished, it can be used within 15 minutes.

Weight

Polyurethane foam only weighs about 2 pounds per square foot once it is open. Compare that to mudjacking, which weighs about 100 pounds per square foot.

Price

Compared to tearing out the concrete and replacing it, polyjacking will save you money. It is also a lot easier and more convenient to have it done with polyjacking.

Environment

Polyurethane foam is nontoxic and environmentally friendly.

Cleanup

Unlike mudjacking, polyjacking is easy to clean and we leave very little evidence we were there. After we leave, you will have a clean area, ready to use.

Customer Reviews

They did an amazing job fixing the issues I had with my backyard patio slab. Dave and Susan were more than accommodating and are extremely professional.
Realseal did a great job repairing the cracks in my foundation. They were very courteous and answered all my question. Clean up was excellent. I highly recommend them.
Had them come out to fix a crack in my basement wall. George was very professional and informative. Job was done well!
This is a great company to have work on any project within their scope. I had a really bad leak from one of my walls and couldn’t find the source. From the first phone call to completion of work the experience was seamless and easy. I called for an estimate, they came same day for the estimate, the next day they did the work, then they did such a great job that I requested them to do more work in other areas of my basement that I knew needed work that I had been holding off for some time. So far they performed well services, two foundation cracks in my basement, and a smile and professionalism throughout the entire process. Paying was easy using their online platform, the process of scheduling was great, and the work is beyond quality and every line item from that quote (and going above and beyond) was completed. No corners cut, no inferior products used, and everything George (my amazing technician) did was explained during the process. I used this company in my previous house and so far so good there have been no issues 4 years in. They did such a great job there that I called them when I moved into this house recently. I requested specially for George on the additional work because of his outstanding work, professionalism, punctuality, and courteous service. I don’t know what other type of service any other company would provide, but I’m going with the company that is true and tried from my own personal experience. If you don’t know much about foundation cracks there will be waterproofing companies that will take advantage of you. The required repairs in my previous house was a simple sealing of my foundation cracks but from another company quoted they told me I needed to repair my French drain, re-trench, take out part of the wall, for a total of $12,500 dollars. Really? These guys came out and fixed my problem there for less than 700 dollars and permanently solved my problems at the old house. Please be careful when you are shopping for quotes, there are companies that will quote you on additional things you do not need. Go with professionals like Real Seal!!!
Issues came up during a home inspection and I called Real Seal for a quote on repairs. Jeff came to do the estimate and he was extremely knowledgeable and thorough. He explained things to me so that I could understand the issues he identified. Jeff was honest and transparent about the repairs explaining that they were not nearly as extensive as previously believed. He emailed a detailed quote within a week.

In the end, we didn't need to do the repair as it wasn't deemed a true hazard. Even though we didn't wind up using their services, I was happy for the in-depth analysis from Jeff and the team.
Real Seal exceeded all expectations! From the moment I reached out, their team responded quickly and professionally. Their customer service was incredibly focused on making sure every question was answered and every concern was addressed with care. You can tell they genuinely care about their clients. The workmanship was excellent — precise, clean, and done right the first time. I highly recommend Real Seal to anyone looking for reliable, high-quality service. A top-tier experience from start to finish!
My 10' x 10' concrete patio slab settled 3-3/4" to 4-3/4" (10-3/4" to 11-3/4" below the tread of the bottom stair riser) and across the width of the 7' stoop. Adjoined to the patio slab is a 3' x 6' concrete pad for two A/C units. I am an architect by profession and I submitted a detailed drawing to The Real Seal for an estimate to saw cut the A/C pad from the patio, thus leaving it level, and to polyjack the patio slab at the stoop in order to regain a proper 7" stair riser. Uneven stair heights are dangerous and not building code compliant. Raising the patio slab at the stoop would also regain the proper slope away from it for drainage. The Real Seal's estimator, Jeff Kowalik, and I met on site, where we reviewed the details and the proposed remediation. Jeff was confident that the desired results were doable. Within days, he emailed a detailed and acceptably priced cost estimate. The work was scheduled within a week after my approving the estimate. The office and field crew provided timely correspondence. A two-man crew, led by Raymund Malvaez, arrived as scheduled, and the sawcutting and polyjacking were completed as designed without incident. They were meticulous in polyjacking the patio slab to the correct elevation across the entire width of the stoop while keeping the A/C slab level and at its existing grade elevation. The small drill holes required for polyjacking were patched and are virtually unnoticeable. A construction sealant was neatly applied between the patio slab and stoop. I couldn't be more satisfied with the overall project experience from start to finish. The Real Seal has my endorsement for professional service as well as outstanding concrete leveling and polyjacking workmanship.
Had a great experience with Real Seal. Jim was so kind and helpful identifying cracks in our basement and came up with a solution to seal them. His proposal was emailed a few hours later. Once we signed the contract, I got a call to schedule the sealing for the next day which was done by noon. I felt no pressure during the experience and walked away feeling great about the work they did. Highly recommend.
If you need basement waterproofing, stop searching and call The Real Seal. Jeff was my estimator, he was knowledgable and friendly. I was provided a quote in timely fashion. Work was scheduled and completed without issue. The guys (George and crew) did a nice job cleaning up. I left my basement wall open for April rains and no more leaking!!! Very pleased with my entire experience and wouldn't hesistate to use them again!
The Real Seal team did a phenomenal job on our project. We needed to lower our basement floor by a couple feet in order to put in a golf simulator. The crew worked tirelessly and went out of their way to protect our home from dust and debris from the process. They were very transparent and communicative, and patient will any questions that I had along the way. I give them my highest recommendation.
Real Seal did an outstanding job for us in replacing our window wells. Great communication and excellent work. We would definitely work with Real Seal again and we very highly recommend them.
Great experience with Real Seal. We moved into a remodel where a former contractor (not sure which company) sealed up a basement leak incorrectly leading to water in our basement months after moving in. Real Seal promptly came out to inspect and consult, quoted a fair price, and then repaired the crack; educating me along the way about what went wrong and how they would repair to ensure there would be no more water. I'm so thankful for their service and lifetime warranty.
Great to work with and clear in explaining how their process works. No pressure on the estimate. Arrived on time, answered our questions and were complete professionals. I would recommend this company. 💯
Sal and Omar arrived on-time and did an excellent job repairing the cracks in the foundation and installing the new piping for the crawlspace sump pump. Sal completed the exterior work in the dark nd cold and took the extra time to make sure it was just right ! The whole process from quote to completed job was what was promised.
Fantastic organization to do business with. The process was professionally handled from the initial call to the end of project. They quickly identified the issue, provided a solution, and quote in the same day. Our yard looks like it was never touched and there was a ton of digging performed. We went through the heavy rains the other day and no issues. Thank you to the entire team!
Fantastic service by Omar and Rob! Would definitely use The Real Seal again!
Our foundation had developed cracks, and the corner of our house was sinking by nearly 3/4 of an inch. After getting multiple quotes, Real Seal offered a competitive price and appeared to be highly knowledgeable. Their warranty was also the best among all the vendors. They scheduled the work for six weeks later and started on time. The project was set for three days, and they completed everything as planned. The crew was professional, respectful, and did an excellent job cleaning up the area afterward. Highly recommend them!
Quality materials, trained and experienced staff that made us feel confident thoroughly the process.... no new decisions were made until we has all options and safety concerns discussed... highly recommend The Real Seal!!!
We had a fantastic experience with Real Seal Basement Waterproofing & Foundation Repair! Rob, the structural engineer, came out first to inspect and assess the damage. He was extremely thorough, professional, and took the time to explain what he was seeing, which helped us feel confident in the next steps.

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.
Real Seal was professional throughout. Communication was clear, and they helped us seal cracks in our basement foundation while also offering helpful guidance on a few home improvements. Initially, their quote was a bit on the higher side, but they worked with us to resolve the issue at a very fair price. We’d definitely use them again.
Jesus and his team did amazing job to install french drain system in our basement. They were fast, efficient, organized and super clean at the site. Everyone in the company is great , very knowledgeable at their job. On top of that their price is very reasonable, highly recommend!
Very pleased with my experience. Hired to install foundation piers.
Real Seal came out and was able to provide a clear, well-thought out plan to address water issues in the basement. The installation of the drain tile system and sump pump was quick, the crew was great, and the system is running very well. Really wonderful job--thanks!
Great Company with excellent employees. Highly recommend !!!!!
I had such a great experience with the real seal. David and Susan were awesome and answered all of my questions when I started the process. The crew that came to install the liner was also amazing they were very respectful, kind, and helpful with any questions that I had. They came the day after a snow storm and the temps dropping and still got everything done.
Promot, efficient, knowledgeable, and reasonably priced. Would hire again.
Great work, super friendly service and very communicative.
Great communication with their team and excellent quality of work. Their specialist went the extra mile on site which we all appreciated. Would definitely rely on them again.
George Ledezma is a very hard worker! He pays attention to details, make sure the jobs are completed to customer satisfaction and is a leader. He deserves a promotion for his loyalty towards Real Seal.
the most dependable and thorough waterproofing company in the Chicagoland area. Been using them since we moved into our house in 2011. Austin and his team consistently crush it.
I can't recommend this company enough. Theirs is by far the best customer service I've ever experienced from any company regardless of the business they're in. There are a lot of choices for basement waterproofing, especially in Chicagoland, but Real Seal is a standout.
The crawlspace to basement conversion was great! The crew clearly knew what they were doing and paid close attention to detail. For such a large project, we had a lot of anxiety going in, but Real Seal went above and beyond to make sure the project went smoothly. Every contractor and inspector who stopped by was also impressed by their work!

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.
I'm so grateful that I got The Real Seal to solve my basement water issues. They sealed several cracks and did drainage work outside to get the water away from my foundation. The guys that did the work were very friendly and knowledgeable.
I never used them personally but they respond to all the comments on their website and offer whatever help they can which is very helpful for DIYer’s like me. If they were in Philadelphia I would undoubtedly use them. Great people.
Great job RealSeal. This is my second sidewalk leveling project. Both have been performed very well.
