Driveway Concrete Leveling with Polyurethane Foam Injection
A sunken or uneven driveway isn’t just an eyesore — it can create trip hazards, drainage problems, and long-term damage if left unaddressed. The good news? In many cases, your driveway can be lifted and leveled without replacing the concrete.
That’s where polyurethane foam injection, also known as polyjacking, comes in.
What Is Polyurethane Foam Injection for Driveways?
Polyurethane foam injection is a concrete leveling method that lifts sunken driveway slabs by injecting a high-density polyurethane foam beneath the concrete.
Here’s how it works:
Small holes are drilled into the affected areas of the driveway
A specialized foam is injected beneath the slab
The foam expands, filling empty spaces in the soil
As it expands, it gently lifts the concrete back to its original level
Once the foam cures, it creates a strong, stable base that supports your driveway for the long term.
Why Driveways Sink in the First Place
Driveways commonly settle due to:
Soil erosion from water runoff
Poor soil compaction when the driveway was installed
Freeze-thaw cycles common in Minnesota climates
Heavy vehicle loads over time
In many cases, the concrete itself is still in good condition — it’s the soil underneath that has shifted.
Benefits of Polyjacking for Driveways
Minimal Disruption
Polyjacking is minimally invasive. The small injection holes are discreet, and there’s no need for heavy equipment, demolition, or tearing out your driveway.
Fast, Same-Day Results
The foam cures quickly, meaning most driveway leveling projects are completed in just a few hours and are often ready to use the same day.
Long-Lasting Support
The high-density foam is strong, durable, and resistant to moisture. Once in place, it helps prevent future settling by stabilizing the soil beneath your driveway.
Cost-Effective Alternative to Replacement
Because the existing concrete is reused, polyurethane foam injection typically costs significantly less than full driveway replacement — without sacrificing performance.
Is Polyjacking Right for Your Driveway?
Polyurethane foam injection is ideal when:
Your driveway has sunken or uneven sections
The concrete is intact (not severely cracked or crumbling)
You want a fast, clean repair instead of replacement
If the concrete is structurally sound but no longer level, polyjacking is often the best solution.
A Smarter Way to Fix Sunken Driveways
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 you’re unsure whether your driveway can be lifted instead of replaced, an evaluation can help you understand your options and make the right call.
