Concrete is everywhere—sidewalks, driveways, pool decks, parking lots, and beyond.
Concrete is widely used in residential and commercial construction for its strength and longevity but is not immune from damage. Cracking, sinking, unevenness, and tripping hazards can befall concrete surfaces, leading to significant disrepair and safety issues.
Bay Area Underpinning understands how frustrating it is to discover and deal with cracking and uneven concrete on your property. Thankfully, the problem can be fixed with concrete leveling. This article will help you understand how the process works and why one option in particular is our favorite.
What is Concrete Leveling?
Concrete leveling is a repair process that lifts concrete back to a safe position. This restores the concrete’s safety, functionality, and appearance simultaneously.
In the home repair world, concrete leveling goes by a few names. You might see the following names used in place of concrete leveling (but they all refer to the same thing):
Other Names for Concrete Leveling
- Concrete repair
- Concrete lifting
- Concrete raising
- Slabjacking
- Slab lifting
- Concrete jacking
- Cement jacking
Depending on who you work with, you might also hear concrete leveling go by one of these more technically specific names:
- PolyRenewal™ (our method), commonly known as “Polylifting,” “Polyjacking,” or “Polyurethane Foam Leveling.”
- “Mudjacking”
- “Stone Grout Slurry Leveling” or “Cement Slurry Leveling”
- “Self-Leveling Concrete”
These methods are designed to lift a concrete surface as close to its original position as possible.
Comparing Concrete Leveling Methods
There are some differences between the four most common concrete leveling methods. Certain methods provide a longer-lasting fix than others. Based on our experience, here are concrete leveling methods ranked from best to worst:
Polyurethane Foam Injection
Polyurethane foam injection can be installed quickly and provides long-term results. The foam cures within 30 minutes and provides incredible strength to the concrete. Polyurethane foam causes minimal disruption to your concrete and provides a longer-lasting result compared to other concrete leveling methods.
Mudjacking
Mudjacking gets its name from the slurry mixture it’s made from. This mixture contains materials like cement, sand, and clay. The solution is pumped beneath concrete to lift and level the structure.
As the mixture cures, it creates a solid, stable base that fills gaps below the concrete and pushes it upwards. However, mud jacking rarely lasts, and it’s a risk to consider.
Due to the materials used in its slurry mixture, mud jacking is susceptible to erosion after rain or snowmelt. As a result, concrete often falls back into a state of damage just a few years (at most) after mud jacking is installed.
Cement or Stone Slurry Concrete Leveling
Stone slurry grout concrete leveling combines mud jacking and polyurethane foam injection techniques, using a mix of crushed stones (mainly limestone) and water. This mixture is installed with special polyurethane injection tools.
It requires drilling large holes (about 1”) for application, offering better control over the material’s thickness and adding significant weight to the soil. Unlike mudjacking, this method effectively fills voids, is environmentally friendly, and durable, though it tends to be a costly option.
Self-Leveling Concrete
Self-leveling concrete, a polymer-fortified cement, is popular because it is user-friendly. It offers a quick-drying, low-water solution for DIY interior floor patching and resurfacing. It’s ideal for small-scale repairs and home improvements, providing a smooth finish without structural reinforcement.
The Cost of Concrete Leveling
Concrete leveling is a complex process, so there isn’t one simple answer to how much it will cost. There are many variables affecting the total cost, including:
- The extent of the damage
- Size of the area requiring repair
- Appropriate repair method
- Amount of product required
- Labor, materials, permits

Which Concrete Leveling Method Should You Choose?
Ultimately, your choice comes down to personal preference. However, we prefer polyurethane injection as it is the fastest, longest-lasting, and least disruptive method available to homeowners. Our team installs PolyRenewal™, our patented version of polyurethane injection.
What is PolyRenewal™?
PolyRenewal™ is our modern approach to concrete leveling. It’s an eco-friendly solution designed to lift concrete without causing a mess or requiring excavation.
Once under the concrete, the foam expands and fills voids between the soil and the slab. As the foam expands, it compresses the soil (making it stronger) and pushes concrete back to a safe level.
What Does PolyRenewal™ Fix?
PolyRenewal™ addresses various concrete problems, including cracking, sinking, and uneven surfaces. It also prevents future issues by stabilizing the underlying expansive soil, which is often the root cause of these problems.
This versatile method can be used on various concrete surfaces, including:

How Do Experts Install PolyRenewal™?
Unlike mudjacking, which requires drilling large holes and pumping heavy materials beneath slabs, concrete lifting with PolyRenewal™ polyurethane injections offers a significantly less invasive approach.
Bay Area Underpinning’s installation teams follow a specific process when applying this solution to concrete structures:
- Complete a thorough concrete inspection to assess the damage.
- Determine necessary repairs, mapping out areas of installation.
- Drill small holes the size of a penny into the affected areas.
- Place injection ports in the drilled holes.
- Mix together a two-part, closed-cell polymer foam.
- Inject the foam under the concrete slabs.
- Allow the foam to expand, fill voids, and cure within 15 to 30 minutes.
- Ensure proper slab lifting and soil stabilization.
- Remove the injection ports.
- Fill and smooth the drilled holes.
- Apply sealant to cracks and joints to prevent further damage.
- Schedule annual maintenance inspections to monitor and protect your concrete slabs.
