Your patio has seen better days. Maybe one corner has dropped an inch or two. Maybe water pools in the middle after every rain. Or maybe you've noticed a growing trip hazard where the patio meets the house. Whatever the symptom, the question is the same: do I have to tear this thing out and start over?
The short answer: almost certainly not.
When Replacement Is NOT Necessary
If the concrete itself is still structurally sound — meaning no large broken pieces, crumbling, or severe spalling — it can almost always be leveled instead of replaced. Common issues that foam leveling fixes include:
- One or more sections settled lower than others
- A gap between the patio and the house foundation
- Water pooling on the surface
- Trip hazards at control joints
- Uneven surfaces causing furniture to wobble
- Hairline to moderate cracks (these are cosmetic and don't prevent leveling)
How Patio Leveling Works
Patio leveling with polyurethane foam is a straightforward process:
- Assessment: We identify which sections have settled and how much correction is needed
- Drilling: Small 5/8-inch holes are drilled through the settled sections (about the size of a penny)
- Injection: Two-part polyurethane foam is injected through the holes. It expands beneath the slab, filling voids and lifting the concrete back to grade
- Patching: The drill holes are filled with matching concrete patch
- Cleanup: We clean up and you're done — walk on it immediately
The entire process typically takes 1-3 hours for an average patio. Compare that to 3-7 days for demolition, forming, pouring, finishing, and curing a new patio.
What About the Cracks?
Many homeowners assume that cracks mean the patio needs replacement. In most cases, that's not true. Hairline and moderate cracks are cosmetic — they don't affect the structural integrity of the slab. Leveling the concrete can actually prevent cracks from getting worse by removing the stress caused by uneven settlement.
If you want to improve the appearance after leveling, cracks can be sealed with a flexible polyurethane caulk that matches the concrete color.
Cost Savings
A typical 200-400 square foot patio costs:
- Foam leveling: $1,000 – $3,000
- Full replacement: $4,000 – $12,000+
That's a savings of 50-75% by choosing leveling over replacement, with the added bonus of keeping your existing patio (and avoiding the mess of demolition in your backyard).
When Replacement IS Necessary
There are a few situations where leveling won't work and replacement is the better option:
- The concrete is broken into multiple large pieces that are no longer connected
- Severe surface deterioration (deep spalling, exposed aggregate falling out)
- The slab is less than 2 inches thick (unusual for patios, but it happens)
- You want to change the size, shape, or design of the patio
