Driveway Leveling & Repair
Sunken Driveway? Lift It — Don't Replace It.
Benchmark Concrete Raising lifts and levels sunken driveway slabs throughout Minneapolis, St. Paul, and the greater Twin Cities metro using polyurethane foam injection. No demolition. No mess. Most jobs completed in a few hours, and the driveway is usable the same day. Free estimates across our entire service area.
Why Driveways Sink
It's a Soil Problem, Not a Concrete Problem
A sunken or uneven driveway creates trip hazards, drainage problems, and long-term damage if left unaddressed. But in many cases, the concrete itself is still in good condition. The problem is the soil beneath it.
The Twin Cities metro sits on clay-heavy soils that expand when wet and contract when dry. Minnesota's freeze-thaw cycles push that movement hard every winter, forming voids beneath concrete slabs as soil shifts or washes away. The slab settles into those voids. Heavy vehicle loads over time compound the problem.
- Soil erosion from water runoff is one of the most common causes of driveway settlement across the Twin Cities
- Poor soil compaction during original installation leaves driveways vulnerable to settling from day one
- Minnesota's freeze-thaw cycle creates new voids beneath slabs each winter as soil expands, contracts, and shifts
- Heavy vehicle loads over time accelerate settlement in areas with already-compromised soil
How It Works
What Is Polyurethane Foam Injection?
Polyurethane foam injection, also known as polyjacking, lifts sunken driveway slabs by injecting high-density foam beneath the concrete through small holes roughly the diameter of a dime. The foam expands, fills voids in the soil, and raises the slab back to its original level. The holes are patched. The driveway is usable the same day.
Because the existing concrete is reused rather than demolished, polyjacking typically costs significantly less than full driveway replacement — without sacrificing durability or performance.
- Small holes are drilled into the affected areas of the driveway
- High-density polyurethane foam is injected beneath the slab
- The foam expands, fills voids in the soil, and gently lifts the concrete back to grade
- The foam cures, creating a strong, stable base beneath the slab
- Injection holes are patched and the site is cleaned up
Why Polyjacking
The Benefits of Lifting Over Replacement
Minimal Disruption
No heavy equipment, no demolition, no hauling away broken concrete. The small injection holes are discreet and the surrounding area is left intact.
Same-Day Results
The foam cures quickly. Most driveway leveling jobs are completed in a few hours and the surface is usable the same day — no waiting for a new pour to cure.
Long-Lasting Support
High-density polyurethane foam is strong, durable, and moisture-resistant. Once in place, it stabilizes the soil beneath your driveway and helps prevent future settling.
Cost-Effective
Because the existing concrete is reused, polyjacking costs significantly less than full replacement. Driveways are one of the surfaces where the cost savings are most significant.
Is It Right for Your Driveway?
When Lifting Works and When It Doesn't
Polyurethane foam injection is the right call when the concrete is structurally intact but no longer level. If your driveway has sunken or uneven sections but the slabs are not severely cracked or crumbling, polyjacking is almost always the better option.
Not every driveway is a good candidate. If the concrete is structurally compromised, we'll say so upfront. We won't take a job we can't do well. If you're not sure whether your driveway can be lifted instead of replaced, an on-site evaluation will give you a clear answer.
- Good candidate: driveway has sunken or uneven sections but the concrete is intact and not severely cracked
- Good candidate: you want a fast, clean repair without the disruption or cost of full replacement
- May need replacement: concrete is severely broken, crumbling, or structurally compromised beyond repair
Common Questions
Driveway Leveling: FAQ
Can a sunken driveway be leveled instead of replaced?
In many cases, yes. If the concrete is structurally intact, polyurethane foam injection lifts sunken slabs back to grade in a single visit at significantly less than replacement cost. We evaluate every job before committing. If replacement is the right call, we'll tell you that upfront.
What is polyjacking?
Polyjacking is a concrete leveling method that lifts sunken slabs by injecting high-density polyurethane foam beneath the concrete through small holes. The foam expands, fills voids in the soil, and raises the slab back to its original level. The foam cures quickly and the surface is usable the same day.
Why did my driveway sink?
Almost always, it's a soil problem beneath the slab. The Twin Cities metro sits on clay-heavy soils that shift with moisture changes, and Minnesota's freeze-thaw cycle accelerates that movement every winter. Soil erosion from water runoff, poor original compaction, and heavy vehicle loads all contribute. The concrete itself is often still in good condition.
How much does driveway leveling cost compared to replacement?
Polyjacking typically costs significantly less than full replacement. Driveways are one of the surfaces where the savings are most pronounced because of the larger surface area involved. We provide free on-site estimates. Call 952-295-0500 or request a quote online.
Is the driveway usable right away?
Yes. The polyurethane foam cures quickly and most driveways are usable the same day the work is completed. No waiting for concrete to cure, no days of blocked access.
Do you serve my area?
We serve communities throughout the Twin Cities metro — Minneapolis, St. Paul, and suburbs across Hennepin, Ramsey, Dakota, Washington, Anoka, Scott, and Carver counties, plus select communities further out like Mankato. Call 952-295-0500 to confirm service to your address.
The Bottom Line
Replacing a Driveway Isn't Always Necessary
Polyurethane foam injection restores safety, improves appearance, and extends the life of your existing concrete — all with minimal disruption to your home and routine. If your driveway is structurally sound but no longer level, polyjacking is almost always the smarter call.
