Signs Your Patio Needs Leveling
- Sunken sections — parts of the patio have dropped below their original level
- Pooling water — settled areas collect rainwater instead of draining
- Uneven surface — adjacent slabs sit at different elevations
- Gaps between slabs — settlement has created openings between patio sections
- Trip hazards — elevation changes create lips that are easy to stumble on
- Sloping — the patio tilts toward the house, directing water toward your foundation
How Patio Leveling Works
The process is the same as general concrete leveling, applied to patio slabs. Material — either mudjacking slurry or polyurethane foam — is injected through small holes in the settled sections, filling voids and lifting the concrete back to level.
Most patio leveling projects are completed in a few hours. With polyurethane foam, the patio is ready to use the same day.
Drainage Considerations
One of the most important reasons to level a settled patio is drainage. When a patio slopes toward your house, rainwater flows toward your foundation — which can lead to water intrusion, basement leaks, and foundation damage. Leveling restores the proper slope so water drains away from your home.
If drainage is the underlying cause of your patio settlement, it should be addressed as part of the project to prevent future settling.
Cost Factors
Patio leveling cost depends on the size of the patio, the amount of settlement, the method used, and accessibility. See our concrete leveling cost guide for details.
Frequently Asked Questions
Yes, in most cases. If the patio slabs are structurally sound but have settled, leveling can raise them back into place. If the concrete is severely cracked or deteriorated, replacement may be needed.
Leveling can restore the proper slope so water drains away from your home instead of pooling on the patio. However, if the drainage problem is caused by grading or downspout issues beyond the patio itself, those may need to be addressed separately.
