Concrete leveling and slab lifting in Fresno solves one of the most common problems homeowners face: sunken, uneven concrete surfaces that create trip hazards and look neglected. Whether it's a driveway that's settled due to expansive clay soils, a patio that's shifted from years of ground movement, or a walkway cracked by seismic activity, we lift and level those slabs without tearing them out and starting over. Fresno's unique terrain, with its mix of hillside lots and clay-heavy soil conditions, makes slab settlement a routine issue across residential neighborhoods. The good news is that lifting works fast, costs far less than replacement, and restores both safety and curb appeal. We've been handling concrete leveling across Fresno, Clovis, Sanger, Selma, and surrounding areas since 2016, and we know exactly how local soil conditions behave.
Why Concrete Leveling Matters in Fresno's Climate and Soil
Fresno's expansive clay soils are one of the biggest culprits behind concrete settlement. As the soil expands and contracts with moisture changes, it pushes and pulls at the foundation beneath your slabs. Combined with the region's seismic activity and the weight of vehicles on driveways, concrete naturally sinks and tilts over time. A sunken slab isn't just ugly; it's a liability. Tripping hazards on patios and walkways can lead to injuries, and uneven driveways damage vehicles and create drainage problems that worsen the settlement.
- We identify the root cause of settlement, whether soil movement, poor drainage, or foundation shifting, before we lift.
- We use polyurethane foam injection to raise slabs to their original level without removing and replacing them.
- We correct trip hazards and improve drainage patterns so water doesn't pool and worsen the problem.
- We restore the value and safety of your property in a single day, with minimal disruption to your home or landscape.
Addressing settlement early prevents costlier damage down the road and keeps your property safe for family, guests, and resale value.
Key info: A driveway in Fresno that has settled 1 to 2 inches might seem minor, but it's a sign that soil movement is active. We lift it back, and proper drainage prevents the cycle from repeating. In Clovis and Sanger, we see the same pattern, especially on hillside lots where drainage and soil stability are critical.

How Concrete Leveling Works: Our Process in Fresno
We don't demolish and rebuild. Instead, we use targeted polyurethane foam injection to lift sunken slabs from beneath. The foam expands under pressure, raising the concrete back to grade while filling voids in the soil. The process is fast, precise, and leaves your slab intact. We start with a site assessment to measure the settlement, identify the cause, and determine the best lifting strategy. Then we drill small ports in the concrete, inject the foam, and monitor the lift in real time until the slab is level and stable.
- We assess the slab with laser levels and measure settlement depth at multiple points across the surface.
- We drill strategically placed ports (typically less than half an inch) to inject polyurethane foam beneath the slab.
- We inject the foam in stages, lifting the slab gradually to avoid cracking and achieving precise level.
- We seal the ports with concrete, leaving no visible trace of the work.
- We verify final grade with laser levels and confirm drainage flow away from the structure.
The entire job typically takes one day, and your driveway, patio, or walkway is ready to use immediately after.
Real example: A homeowner in Fresno 93721 had a driveway that settled 3 inches at the street end, creating a severe trip hazard and trapping water. We injected foam at 12 points, lifted the slab back to grade in about 4 hours, and sealed the ports. No removal, no replacement, no weeks of cure time. The driveway is level and safe again.

Concrete Leveling Methods: Comparing Approaches
| Method | How It Works | Best For |
|---|---|---|
| Polyurethane Foam Injection | Expanding foam is injected beneath the slab through small ports, lifting it back to grade while filling soil voids. | Driveways, patios, walkways, and garage slabs with minor to moderate settlement. Fast, clean, and no cure time needed. |
| Mudjacking (Slab Jacking) | A slurry of soil, cement, and water is pumped beneath the slab, raising it and filling voids underneath. | Larger commercial slabs or situations where foam injection is not suitable. Requires 24 to 48 hours cure time. |
| Concrete Removal and Replacement | The sunken slab is demolished, the soil is graded and compacted, and new concrete is poured to the correct level. | Severely cracked or damaged slabs, or when soil conditions require deep remediation before new concrete is laid. |
| Soil Stabilization Before Lifting | We address the root cause (poor drainage, expansive soil) before lifting, preventing future settlement. | Properties with ongoing settlement issues or where preventing recurrence is a priority. Often combined with foam injection. |
Concrete Leveling and Slab Lifting Cost in Fresno: What to Expect
Concrete leveling starts at $4 per square foot as a baseline for polyurethane foam injection on residential driveways and patios. A typical driveway of 400 square feet might run $1,600 to $2,400, depending on the extent of settlement and the number of injection points needed. The final cost depends on several factors: how much the slab has settled, the size of the area, accessibility for equipment, soil conditions, and whether we need to address drainage or other underlying issues. A patio with minor settlement costs less than a driveway with deep voids that require multiple lifting stages. We always provide a free, no-obligation estimate so you know the exact price before we start.
- Settlement depth and the number of injection points required directly affect the total cost of the job.
- Access to the slab, such as tight spaces or obstacles, may increase labor time and pricing.
- Soil conditions in Fresno's expansive clay zones sometimes require additional stabilization, adding to the estimate.
- Mudjacking or removal and replacement will cost more than foam injection, typically $5 to $8 per square foot.
Getting two or three estimates from licensed contractors ensures you understand the scope and price before committing. See our full pricing overview for detailed breakdowns by service type and job complexity.
Concrete Leveling and Slab Lifting Near Me: What Fresno Homeowners Should Know When Hiring
Not all concrete contractors have the equipment and expertise for slab lifting. When you're looking for concrete leveling and slab lifting near you in Fresno, Clovis, Sanger, or nearby areas, focus on a few key credentials and practices. First, verify that the contractor is licensed with the California State License Board (CSLB) and carries liability insurance and workers' compensation. Concrete lifting requires specialized equipment and training, so ask about their experience with polyurethane foam injection and how many projects they've completed in the Fresno area. Request references from recent jobs, especially residential driveways or patios similar to yours. Ask whether they handle local permitting for sidewalk or driveway work if it involves right-of-way or curb cuts. Finally, get at least two estimates and understand what's included: are ports sealed? Is site cleanup covered? Is there a warranty on the lift?
- Confirm CSLB C-8 license and current liability and workers' compensation insurance before hiring.
- Ask about experience with polyurethane foam injection and request references from at least three recent residential projects.
- Verify that the contractor understands local soil conditions and settlement patterns common to Fresno and the Central Valley.
- Clarify whether permitting for driveway or sidewalk work is included, especially if the slab touches the right-of-way.
- Request a written estimate that breaks down labor, materials, and any additional costs, with a timeline for completion.
