Mudjacking is a concrete leveling technique where a cement-based slurry is pumped under sunken slabs to lift them back to the proper level. We drill small holes through the concrete, inject the material underneath, and the hydraulic pressure raises the slab. The holes are patched afterward. Mudjacking is cost-effective and works well for driveways, sidewalks, patios, and garage floors. It is much cheaper than full replacement and can be completed in a few hours with minimal disruption.

How long does concrete leveling last?

When done properly, concrete leveling can last 5 to 10 years or more depending on the cause of the original settling. If the soil underneath is stable and drainage is good, leveled concrete can last as long as the original installation. However, if the underlying soil continues to settle or erode, further sinking may occur. We assess the reason for settling and address drainage or base issues when possible to ensure long-lasting results. Leveling is a fraction of the cost of replacement even if it eventually needs to be redone.

Is polyurethane foam injection better than mudjacking?

Polyurethane foam injection (also called polyjacking or foam jacking) has some advantages over traditional mudjacking. The foam is lighter weight, so it puts less stress on weak soil. It cures quickly, so the surface can be used within hours instead of days. The injection holes are smaller and less noticeable. However, foam is more expensive per job. For heavy slabs and large areas, mudjacking may be more economical. We offer both methods and recommend the best option based on your situation and budget.

Fix Sunken Concrete Without Replacement

Sunken or settled concrete is a common problem that creates uneven surfaces, trip hazards, and drainage issues. Driveways, patios, sidewalks, and garage floors can sink when the soil underneath shifts, compacts, or washes away. The traditional solution was to tear out and replace the concrete, which is expensive, messy, and time-consuming. Concrete leveling offers a better alternative that lifts and levels sunken slabs at a fraction of the cost and in just a few hours.

Also known as slab jacking, mud jacking, or foam jacking, concrete leveling involves injecting material under the slab to fill voids and raise the concrete back to its original position. This process is fast, affordable, and minimally invasive. You can use the surface within hours instead of waiting days for new concrete to cure. Leveling works on most concrete surfaces and can solve problems that would otherwise require costly removal and replacement.

We provide professional concrete leveling services throughout Florence-Graham and surrounding areas. Our experienced crews use proven methods to restore your concrete surfaces quickly and effectively. Whether you have a sunken driveway section, uneven patio, or dangerous sidewalk trip hazard, we can help. Visit our homepage to learn about all our concrete repair and installation services.

How Concrete Leveling Works

The concrete leveling process is straightforward and causes minimal disruption to your property. Here is what to expect when we level your sunken concrete.

Site Assessment

We start by inspecting the sunken areas and measuring how much the concrete has settled. We check for cracks, voids underneath, and any drainage problems that caused the settling. This evaluation helps us determine if leveling is the right solution and how much material will be needed. Not all sunken concrete can be leveled successfully. Severely damaged or cracked slabs may need replacement instead.

Drilling Injection Holes

Small holes about one to two inches in diameter are drilled through the concrete at strategic locations. These holes give us access to the space underneath where we will inject the leveling material. The number and placement of holes depend on the size of the area and how much it has settled. Drilling is done carefully to avoid damaging the slab.

Injecting Leveling Material

We pump leveling material through the holes into the voids beneath the concrete. The material fills empty spaces and creates pressure that lifts the slab. We monitor the lift carefully and adjust injection points as needed to achieve level results. The process is controlled and precise, allowing us to raise the concrete in small increments until it reaches the desired height. Traditional mud jacking uses a cement slurry mix, while polyurethane foam injection uses expanding foam that is lighter and cures faster.

Finishing and Cleanup

Once the slab is level, the injection holes are filled with concrete and smoothed to match the surrounding surface. The area is cleaned and ready for immediate use in most cases. Polyurethane foam cures in about 15 minutes, while cement slurry takes a few hours. The result is a level surface that looks and functions like new without the cost and disruption of replacement.

Benefits of Concrete Leveling

Concrete leveling offers significant advantages over replacement, making it the smart choice for most sunken slab situations. Here is why property owners choose leveling over removal and replacement.

Cost Effective: Leveling typically costs 50 to 70 percent less than removing and replacing concrete. You get great results without breaking the bank.
Fast Process: Most leveling projects are completed in a few hours. You can use the surface the same day instead of waiting a week or more for new concrete.
Minimal Disruption: No heavy equipment, extensive excavation, or landscape damage. The process is clean and does not tear up your property.
Environmentally Friendly: Leveling reuses existing concrete instead of sending it to landfills and producing new concrete with its carbon footprint.
Prevents Further Damage: Addressing settling early prevents water infiltration, additional cracking, and more extensive problems down the road.
Improves Safety: Eliminating uneven surfaces and trip hazards protects family members, guests, and visitors from injury.
Restores Drainage: Leveling corrects slopes and allows water to drain properly instead of pooling on the surface.

These benefits make leveling an attractive solution for homeowners and businesses dealing with settled concrete. The combination of low cost, fast results, and minimal disruption cannot be matched by replacement. For severe damage that cannot be leveled, we also offer concrete replacement services.

Common Applications for Concrete Leveling

Concrete leveling works for many types of settled slabs around your property. Here are the most common applications we handle for residential and commercial customers.

Driveways: Sunken driveway sections create drainage problems and cause vehicles to bottom out. Leveling restores smooth transitions and proper slope.
Sidewalks: Uneven sidewalk sections are major trip hazards and liability issues. Leveling eliminates dangerous height differences between slabs.
Patios: Settled patios collect water and become unusable. Leveling restores proper drainage and creates a smooth surface for furniture and activities.
Garage Floors: Sloped garage floors allow water to run toward the foundation or create uneven parking surfaces. Leveling fixes these issues quickly.
Pool Decks: Settled pool decks create trip hazards and drainage problems. Leveling is ideal because it does not require draining the pool or extensive excavation.
Commercial Walkways: Business owners need safe level walkways for customers and employees. Leveling is fast and allows business to continue with minimal interruption.

Any settled concrete surface is potentially a candidate for leveling. We evaluate each situation and let you know if leveling will work or if replacement is necessary. For new concrete installations, check out our driveway services and other concrete work.
