Concrete Raising

Polyurethane Slabjacking - Polyjacking!

Polyurethane Concrete Raising Experts

The preferred solution for lifting sunken concrete

Problem: Settled and Sinking Concrete

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. Overtime sunken slabs such as driveways, patios, and garage floors can become dangerous trip hazards, divert water towards your home and can make your property look just plain ugly. Sunken concrete is a very common issue many Illinois property owners are faced with and luckily there is an easy and affordable solution.


Solution: Polyurethane Slabjacking – Polyjacking!

Catalano Concrete to the rescue! High-density polyurethane gets injected below the sunken slabs as a two-part polymer. Our high performance expanding geotechnical foam not only raises and levels the sunken slab but also fills open voids and stabilizes loose soil, which reduces the chance of future settling.   The life of the concrete has now been extended all in a matter of minutes and can be put back to use immediately.  Polyjacking is the quickest, cleanest and longest lasting method for repairing sunken concrete.

Why use Polyurethane to Raise Concrete?

SUPER STRONG! Polyurethane cures as an inert, impermeable polymer that will not shrink, breakdown or wash away.

LIGHTWEIGHT! Polyurethane weighs about 2.5 per cubic foot, which doesn’t add much, unwanted weight to an already failing substrate.

STABILIZATION! Since polyurethane is injected as a liquid it is extremely effective at filling open voids, and solidifying and stabilizing  loose soils.

LESS INVASIVE! The polyurethane injection process uses penny-size holes making our work barely noticeable.

IT’S FAST! Polyurethane cures extremely fast which means you can go back to using your concrete right after we leave.

IL Concrete Leveling Services

Driveway Leveling

Replacing a concrete driveway is no easy task (we know because we do it everyday).  Be prepared for 2-3 days of construction and another 7 days of parking on the street to allow for curing.  Also, some landscape restoration we be needed after completion and of course you will need to obtain a permit from the village before any work takes place. Average driveway replacements in the Chicago area cost $5,000 -$7,000.

Due to the hassle and high cost, many homeowners are choosing to extend the life of their current driveway with our raising and  leveling services.  Our advanced polyurethane concrete raising system is completed in hours not days and cost a fraction of replacement.

Patio Leveling

As the soil around a home settles, its very common for patios to sink as well. Sunken patios that are pitched towards your home are not only an eye sore but can also create major water problems to your homes foundation and basement.  Installing a new patio is an extremely expensive and invasive process and luckily it is typically not needed if the slabs are still in good shape but have just settled.

Our polyurethane injection system (Polyjacking) is an effective and popular method for raising and leveling sunken patios. The high-density polymer material will not shrink, wash away or breakdown which creates a long-term repair and the injections holes are the size of a penny making the repair almost unnoticeable.

Walkway Leveling

We’ve all been there.  You’re walking along a walkway and suddenly you trip over a section of uneven concrete causing you to trip and possibly fall.

The Americans with Disabilities Act defines a trip hazard as any vertical change over ¼ inch at any joint or crack in the concrete. Because the ADA demands strict compliance and places direct responsibility on the property owners, trip and fall hazards left unrepaired can lead to significant legal liability.

Concrete raising & leveling is the ideal solution for quick and affordable trip hazard repairs.   Our non-invasive system effectively raises walkway slabs back into place without needing costly replacement.

The Polyjacking Process

Our state-of-the-art Polyjacking concrete raising process is the most advanced and effective way to raise and level concrete. It can be done quickly (usually less than an hour) with minimal disruption to surrounding area and concrete can be used minutes after we leave.

It begins with our trained professional estimator visiting the site, taking measurements and leaving a detailed estimate. This can be done without needing to be home unless it’s an interior slab.

Drill: Once our crew arrives, small 5/8” penny size holes are strategically drilled into your sunken slab. Any dust that is created is quickly vacuumed away.

Pump: After the small holes are drilled, our technician then carefully injections a two part liquid polymer into each hole. The material is stored in our trailer and pumped through a heated hose and then discharges through our specialized spray gun. The two-part liquid turns into expanding foam once mixed below the slab. The expanding polyurethane foam quickly fills open voids, stabilizes weak soil and lifts the slab. The technician carefully monitors the process to ensure a perfect lift

Patch: Once all the concrete slabs have been fully lifted, leveled and stabilized, the technician then fills each small hole with grout to ensure a tight seal. Your concrete is now back to where it should be and ready for use!

Polyjacking vs. Mudjacking

While mudjacking is an older process for raising concrete, it does have its weakness. When researching the best method for raising concrete we and many other contractors have discovered that Polyjacking concrete raising is less invasive, long lasting, cleaner and faster when compared to mudjacking. Read below to learn why more and more homeowners and property managers are using Polyjacking to raise and level their sunken concrete.

Less Noticeable…

Polyjacking Concrete Raising vs Mudjacking - Catalano ConcreteSmaller Injection Holes: A key benefit many property owners love about using polyurethane to repair concrete compared to mudjacking are the smaller holes that are required. Our polyurethane method only requires 5/8” holes (the size of a penny) compared to 1”-2” size holes needed for mudjacking. Our process produces a nearly invisible end result. This is especially important when repairing decorative stamped concrete.

Fewer Holes: Our polyurethane foam needs fewer holes to be drilled in your concrete for a cleaner look compared to mudjacking. Because polyurethane foam is sprayed below the slab as a highly pressurized liquid, we can cover a larger area from each injection port. The foam can flow and expand from 4 to 15 feet from each injection port. Since mudjacking uses a heavy slurry, only 1-2 feet can be covered below the slab from each hole. This means more holes are needed to raise and level concrete when using mudjacking. Those who prefer their concrete to not look like Swiss cheese after it’s raised prefer using our polyurethane method.

Long Lasting Repair…

Lightweight: Mudjacking uses a grout made of sand, cement, and water. On average this can weight around 100lbs per cubic foot. This heavy material can put more burden on an already weak base which can cause future settling to occur. Polyurethane on the other hand only weighs 2lbs per cubic foot. Which means our lightweight material will put much less (about 50 times less!) weight on your base which decreases the chance of future settling when compared to mudjacking.

Non-Shrinking Material: Our polyurethane material is made from environmentally safe materials and becomes an inert, high-density solid material minutes after it’s injected and will forever keep its shape and strength. Mudjacking, on the other hand, is made from water, sand, and cement, which means it can shrink, wash away and can be susceptible to moisture and erosion.

Cleaner & Faster Process…

Cleaner: Our material is contained in our specialized trailer, it is then pumped to each injection port through a hose. That’s it! Unlike mud jacking, there is no need for heavy equipment to be used on your property and messy grout spills to be cleaned. Also, since our holes are so small, there is less dust created compared to mudjacking. Of course, any dust that we do create is quickly vacuumed up!

Faster: Once the polyurethane is pumped in it only needs 15 minutes to cure before it’s ready for cars to drive over the concrete. No need to wait days to get your car back in your garage, which is the case with mudjacking. Business owners can also allow customers and employees to use the area immediately after we leave.

Raising Concrete vs. Replacing Concrete

We decided to add concrete raising services to our service offerings because we knew there was a better way to repair concrete slabs that have sunk due to a failed base. Many of our customers were spending money replacing structurally sound concrete that just needed to be raised. After a year of research, we decided to offer our customers the most effective alternative to replacement. Below are the reasons why concrete raising may be a better choice for repairing sunken concrete.

  • Cheaper: Raising concrete is normally around 50% to 70% less than having it replaced!
  • Faster: Our raising process can be completed in 30-60minutes compared to days with replacement.
  • Easier: No need for permits, inspections, and all the noise, dust and other things that are part of the concrete construction.
  • Greener: If are trying to do your part to minimize your environmental footprint, then raising your concrete rather than replacing it is one way to do it.

Of course, not all concrete can be raised. If there are many structural cracks than replacement might be the only option. Set-up a free estimate and evaluation to learn which option is best for you!
