Concrete Lifting in Salt Lake City, UT
Concrete lifting in Salt Lake City with polyurethane foam injection to raise sunken slabs fast, no demo, free estimates.
Serving Salt Lake City and nearby communities.
A sunken slab doesn't need to be torn out and repoured. Salt Lake City Foundation Experts uses polyjacking, polyurethane foam injection through dime-sized holes, to raise settled concrete back to grade in hours instead of days. It's the same lifting principle used on driveways, patios, and sidewalks, applied here to any slab that's dropped due to soil movement under the Salt Lake Valley's freeze-thaw cycles.
Most slabs settle because the soil underneath loses compaction, often from water washing out fines after winter snowmelt or from the valley's clay content shrinking and swelling. Instead of mudjacking's heavy slurry, we inject lightweight hydrophobic foam that expands to fill voids and lift the slab without adding load the weakened sub-base has to carry.
What's included
What's included with Concrete Lifting
Typically included: slab inspection and void mapping, drilling access holes, polyurethane foam injection to lift the section, elevation checks during lift, and hole patching to match the surrounding surface.
Optional: joint resealing on adjacent slabs, minor surface crack sealing, drainage slope correction on the lifted section.
Customer prep: clear furniture, planters, or vehicles from the work area and point out any slab sections that have shifted or cracked.

How our Concrete Lifting process works
Step 1Surface Assessment
Uneven or sunken concrete areas are identified and measured.
Step 2Drilling Access Holes
Small holes are drilled into the concrete to allow material injection.
Step 3Material Injection
Expanding foam is injected beneath the slab to raise it evenly.
Step 4Elevation Monitoring
Lift progress is measured to achieve the desired level.
Step 5Hole Patching
Access holes are filled and finished to match the surrounding surface.
Step 6Final Inspection
The lifted area is reviewed for levelness and stability.
Materials
Materials and methods for Concrete Lifting
A lifting job is only as good as what goes under the slab. We use materials built for void-filling and long-term stability, not just a quick cosmetic fix.
Polyurethane Foam
Expands beneath slabs to lift and stabilize concrete surfaces without adding the weight that can re-compress soft valley soil.
Injection Ports
Allow controlled placement of lifting material under the slab so adjoining sections lift evenly.
Patch Compound
Fills drilled access holes for a smooth finish that blends with the original pour.
Surface Sealant
Protects the repaired area from moisture and staining, important given SLC's freeze-thaw winters.
Leveling Gauge
Used to measure and confirm slab elevation during lifting so the finished grade matches neighboring concrete.
Bonding Agent
Improves adhesion between new patch material and existing concrete for a durable repair.

What does concrete lifting cost in Salt Lake City?
Cost depends on slab size, how much the section has settled, and how many injection points are needed to achieve an even lift. These are ballpark ranges, not a fixed quote. Call for a free estimate based on your slab.
| Project type | Typical range | What’s included |
|---|---|---|
| Small section lift | $400-$900 | single slab panel with minor settling. |
| Driveway or garage floor | $1,000-$2,500 | multiple panels and deeper void fill. |
| Large patio or combined areas | $1,500-$4,000 | broader coverage with slope correction. |
These are typical local ballparks — final cost depends on scope, materials, and site conditions. A free estimate gives you an accurate, itemized number for your home.

DIY vs hiring a pro for Concrete Lifting
| DIY | Hire a pro |
|---|---|
| Filling small surface cracks with a patch kit | Lifting a slab evenly, since uneven DIY mudding doesn't fill the void underneath and the slab keeps settling |
| Monitoring a slight dip to see if it worsens over a season | Any area near a foundation wall, downspout, or drainage path where the wrong fix sends water toward the house |
| — | Slabs larger than a single small panel, where uneven lift can crack concrete further |

FAQs
Concrete Lifting FAQs
How much does concrete lifting cost in Salt Lake City?
Most residential slab lifts run $400 to $2,500 depending on slab size and settlement depth, with larger combined areas running higher.
Is polyurethane foam lifting actually permanent?
The foam itself doesn't break down or wash out, but if the underlying soil keeps moving the slab can still shift again over time. That's why we check for drainage issues as part of the inspection.
How is concrete lifting different from slab replacement?
Lifting raises the existing slab using foam injected underneath, while replacement means tearing out the old concrete and pouring new. Lifting is faster and considerably less expensive when the slab itself is still in good shape.
Can concrete lifting fix a sloped slab that's draining water the wrong way?
We can often use injection to correct slope along with raising the low point, redirecting water away from the foundation instead of toward it.
Will the drilled holes be visible after the repair?
The access holes are patched and finished to blend with the surrounding concrete. Some color variation is normal, especially on older, weathered slabs.
How soon can I drive or walk on the slab after lifting?
Foam reaches working strength quickly, usually within an hour, so most slabs are ready for normal use the same day.
Do you lift slabs that are badly cracked?
If a slab is badly cracked or broken into pieces, lifting may not hold. We'll tell you honestly during the inspection if replacement makes more sense.
