Signs Your Driveway Needs Leveling
- Sinking or sloping sections — parts of the driveway have dropped below their original level
- Cracks — settlement stress causes cracks as the slab shifts
- Pooling water — low spots collect rainwater instead of draining
- Gaps at the garage or street — the driveway has pulled away from the foundation or curb
- Uneven surface — adjacent slabs sit at different elevations
- Trip hazards — elevation changes create lips that are easy to stumble on
How Driveway Leveling Works
The process is the same as general concrete leveling, applied specifically to driveway slabs:
- Inspection — The driveway is assessed to determine the cause of settlement and the best method.
- Drill access holes — Small holes are drilled through the sunken sections.
- Inject material — Mudjacking slurry or polyurethane foam is pumped beneath the slab.
- Lift and level — The slab is raised to the correct elevation.
- Patch and clean up — Holes are patched, and the driveway is ready for use.
Mudjacking vs. Polyurethane Foam for Driveways
Both methods work well for driveways. Mudjacking is more cost-effective for large driveway areas. Polyurethane foam is better if you need to use the driveway the same day or if the soil beneath is weak. See our comparison guide for details.
Driveway Leveling vs. Replacement
If your driveway is structurally sound but has settled, leveling is almost always the better choice — it costs 50-70% less and avoids the mess and downtime of demolition and repouring. However, if the concrete is severely cracked, crumbling, or has widespread surface damage, replacement may be the better long-term investment.
Cost Factors
Driveway leveling cost depends on the size of the settled area, the amount of drop, the method used, and accessibility. See our concrete leveling cost guide for details.
Why Driveways Settle in Minnesota
Minnesota's freeze-thaw cycles are tough on driveways. Water seeps beneath the slab, freezes and expands, then thaws and leaves voids. The driveway settles into those voids. Poor drainage and soil compaction issues make the problem worse. Learn more in our guide to why concrete sinks in Minnesota.
Frequently Asked Questions
Yes, in most cases. If the driveway slab is structurally sound but has settled, leveling can raise it back into place. If the concrete is severely cracked or crumbling, replacement may be needed.
With polyurethane foam, the driveway is typically ready for vehicle traffic within 30 minutes. With mudjacking, you should wait 24-48 hours before driving on it.
