Sunken concrete? No problem, Polylift it!
PolyLift: Concrete Lifting & Leveling
The days of living with sunken concrete or spending a fortune on replacement are gone! PolyLift is a concrete raising technique which uses high-density polymer to lift, level and stabilize settled concrete slabs. The process is a quick, easy and cost-effective alternative to concrete replacement and has many advantages compared to other concrete repair methods, such as mudjacking.

Why repair settled concrete?
Why concrete sinks and the problems it can create.
Nothing last forever and that includes concrete. This is especially true in Illinois where we experience extreme seasonal cycles which causes the ground to shift. This can lead to concrete sinking and cracking overtime. Also, concrete built over poorly compacted stone and soil, especially around your home, is susceptible to settling over time especially as water penetrates below through cracks, joints, and open sides, and erodes the base material.
- Become dangerous trip hazards
- Divert water towards your home causing other larger problems
- Create ugly eye sores that reduce curb appear and property value
Concrete Hero uses advanced technology to lift and level concrete!
Leveling Concrete the Hero Way
Typically there have been two options when correcting sunken concrete. The first would be replacement, which can be extremely costly, time consuming and inconvenient. The second was mudjacking, which works by pumping a cement and sand slurry below a slab to lift it back up. Mudjacking has been a popular method in the past however it was never regarded as a long-term solution since the slurry material tends to break down over time and the heavy weight of the material can cause the slab to re-settle again.
We Use the Power of Polyurethane!
Concrete Hero to the rescue! Our PolyLifting system is an extremely effective method used for extending the life of concrete. The process is similar to mudjacking but the results are longer lasting and less invasive. The system works by injecting high-density polymer below a sunken concrete slab, causing it to raise to its intended position while also stabilizing loose soil. The polymer is light weight and extremely strong which makes it a longer-lasting repair option when compared to traditional mudjacking.
Our state-of-the-art PolyLift system is the industry’s preferred method for effectively raising and leveling sunken concrete. Once completed, the life of the concrete has been extended and can be put back to use immediately. PolyLifting is the quickest, cleanest and longest lasting method for repairing sunken concrete.
Polyurethane cures as an inert, impermeable, solid polymer that will not shrink, breakdown or wash away. This means once the polymer is installed, its not going anywhere.
Polyurethane only weighs about 2.5 - 3.5lbs per cubic foot, so it doesn’t add much weight to an already failing substrate. This means the chance of the concrete re-settling is greatly reduced.
Replacing concrete is extremely expensive. On the other hand, raising sunken concrete is typically 50%-80% less than replacement, saving you a lot of money.
Polyurethane is injected as a liquid, so it is very effective at filling open voids, solidifying and stabilizing loose soils.
The polyurethane injection process uses penny-size holes making our work barely noticeable.
Only a few hours to complete and it cures fast, so you can go back to using your concrete right after we leave!
The PolyLift Process
Step 1: Drill
Once our crew arrives, small 5/8” dime size holes are strategically drilled into your sunken slab.
Step 2: Pump
The technician now carefully injects a two part liquid polymer into each hole. The liquid turns into expanding foam once mixed below the slab, quickly filling open voids, stabilizing weak soil and lifting the slab.
Step 3: Patch
Once all the concrete slabs have been fully leveled and stabilized, the technician fills each small hole with grout to ensure a tight seal. Your concrete is now back to where it should be.
Step 4: Enjoy!
As soon as our crew leaves you are ready to begin enjoying your restored concrete again. No waiting time!
Common Polyurethane Concrete Leveling Questions
What is the average cost to lift my concrete with polyurethane?
Raising concrete is an extremely affordable option when compared to replacement. Since every job is unique in terms of the amount of material needed and the size of the area being raised, giving an average cost is difficult. In general, raising concrete with polyurethane is typically 50%-80% less than replacement. Most front walkway leveling projects are around $500-$900 and driveways and patios are around $600-$1,500. The size of the area and the amount it has sunk are the biggest factors that determine the price. You can learn more about this by reading our average cost page.
Polyurethane foam vs mudjacking – which is better?
Both methods will certainly lift and level your concrete however there are many advantages to using polyurethane over mudjacking. Below are the main advantages and benefits to using polyurethane over mudjacking:
Longevity: Since polyurethane is extremely lighter than mudjacking material the chance of re-settling is greatly reduced.
Appearance: Polyurethane requires much smaller injection holes, making the work much less noticeable than mudjacking.
Process: A much cleaner process and the area is usable 15 minutes after installation vs 24 hours with mudjacking
Contractors who argue that mudjacking is the best method are either misinformed or are just reluctant to update their equipment and process. You can learn more about in greater detail by checking out are polyurethane vs mudjacking page.
How long will my raised concrete stay level?
This is a very common and important question. Our polyurethane since it’s a synthetic material, will not change shape or breakdown like other materials such as sand or cement. However the ground can and will move overtime depending on soil conditions, especially with the frost cycles we experience here in the Midwest. Also, water intrusion from poor drainage can erode the soil, which can cause re-settling. Lastly, a long dry spell over the summer can cause the ground the shrink, which can impact your concrete. So typically if there is any re-settling it’s most likely due to soil conditions, poor drainage or extreme weather all of which would also affect new concrete.
What can be done to prevent my concrete from sinking?
The key to preventing concrete from sinking is by filling voids and keeping water away. Open voids below your concrete should be stabilized with polyurethane foam. All open gaps such as cracks and expansion joints should be caulked to stop water from getting below the slab and eroding the base. Also, all water should be directed away from your concrete such as downspout. The sides of your concrete should also be properly graded so that the base cant wash away.
