How long does concrete leveling last?

Concrete leveling can last 5 to 10 years or more, depending on soil conditions and the quality of the work. In many cases, leveling provides a permanent solution, especially when combined with improvements to drainage that prevent future settling.

Can all sunken concrete be leveled?

Most sunken concrete can be successfully leveled, but there are exceptions. If the concrete is severely cracked, broken into multiple pieces, or structurally compromised, replacement may be the better option.

Will the leveled concrete settle again?

In most cases, properly leveled concrete remains stable for years. The leveling material fills voids and provides support that was missing, which helps prevent future settling. However, if the underlying cause of settling is not addressed, the concrete could settle again over time.

What Is Concrete Leveling and Why You Need It

Concrete leveling, also called slab jacking or mud jacking, is a process that lifts and stabilizes sunken concrete slabs. When soil underneath your concrete settles, washes away, or compacts over time, sections of your driveway, sidewalk, or patio can sink and become uneven. This creates trip hazards, drainage problems, and an unsightly appearance that brings down your property value.

The good news is that you do not always need to replace the concrete. Leveling is a cost-effective alternative that can restore your concrete to its original position in a fraction of the time and at a fraction of the cost of replacement. We drill small holes in the sunken slab, inject a specialized material underneath, and lift the concrete back to the proper level. The process is quick, minimally invasive, and delivers long-lasting results.

Concrete leveling is ideal for driveways, sidewalks, patios, garage floors, and pool decks that have settled but are otherwise in good condition. If the concrete is severely cracked or damaged, replacement may be necessary, but for most settling issues, leveling is the smart, affordable solution.

How Concrete Leveling Works

The Leveling Process

We start by evaluating your sunken concrete to determine the extent of the settling and the best approach for lifting it. We measure the elevation differences and identify the areas that need to be raised. Then we drill small holes, typically about the size of a quarter, in strategic locations across the sunken slab.

Through these holes, we inject a lifting material, either a specialized polyurethane foam or a cement-based slurry, depending on the application and your needs. The material fills the voids beneath the slab and expands or hardens, creating pressure that lifts the concrete. We carefully control the injection to raise the slab gradually and evenly to the desired level.

Once the slab is level, we patch the injection holes with fresh concrete that blends with the existing surface. The leveling material cures quickly, and the concrete is usually ready to walk on within hours and ready for vehicles within a day. The entire process typically takes just a few hours, causing minimal disruption to your daily routine.

Polyurethane vs Traditional Methods

Traditional mud jacking uses a heavy cement-based slurry to lift concrete. This method has been around for decades and works well in many situations. However, the slurry is heavy and can add weight to already compromised soil, potentially leading to future settling.

Polyurethane foam leveling is a newer technology that uses lightweight foam to lift the concrete. The foam is extremely strong, weighs much less than mud jacking material, and expands to fill voids completely. It cures faster and does not add significant weight to the soil. We offer both methods and help you choose the best option based on your specific situation, soil conditions, and budget.

Benefits of Concrete Leveling

When you choose concrete leveling from NWC Norwich Concrete, you get a solution that saves you time, money, and hassle. Here are the key advantages:

Costs 50 to 70 percent less than complete concrete replacement
Fast completion with most jobs finished in just a few hours
Minimal disruption to your property and landscaping
No demolition, hauling, or disposal of old concrete
Concrete is ready to use within hours, not days
Eliminates trip hazards and improves safety
Restores proper drainage and prevents water pooling
Extends the life of your existing concrete for years

Leveling also avoids the environmental impact of tearing out and replacing concrete. You keep your existing slab out of the landfill and use fewer new materials. This makes leveling an eco-friendly choice that still delivers excellent results.

Another advantage is that leveling maintains the existing appearance and character of your concrete. If you have decorative stamped or colored concrete, replacement would mean losing that custom finish. Leveling preserves your investment and keeps your concrete looking the way you want it.
