Fix That Sinking Patio Without Replacing It
A sinking patio can ruin the look of your backyard — and make it tough to enjoy your space. Whether it’s pulling away from your house, tilting toward your yard, or full of trip hazards, we can help. RaiseRite uses polyurethane foam to lift and level patios quickly, without tearing anything out. Most jobs take just a few hours, and you can get back to enjoying your yard the same day.
Why Do Patios Sink?
Most patios are poured on compacted soil or backfill — but over time, that base can shift. Water runoff, erosion, or poor compaction during construction can cause the soil to settle unevenly. This leads to slabs cracking, sinking, or pulling away from steps or your foundation. The longer it goes untreated, the worse it gets.
If your patio isn’t the only issue, we can also lift driveways, garage floors, walkways, steps, porches, slabs, interior floors, and pool decks. You can also view all residential concrete leveling services.

What Are the Signs You Need Patio Leveling?
Sunken patios aren’t just annoying — they’re often a sign of bigger problems beneath the surface. Look for:
Patio slabs pulling away from your home or steps
Pooling water where it used to drain away
Cracks running across or between slabs
Unlevel joints creating trip hazards
Chairs, tables, or grills that don’t sit flat
Our Fix: Quick, Clean Concrete Leveling with Foam
Step 1) Injection holes are strategically drilled around the areas where the concrete is sunken and requires lifting.

Step 2) Once everything is prepped, and the hose and material are in place, the polyurethane foam is injected through the holes. It expands to fill the space underneath the concrete slab, using the slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original position.

Step 3) Once the concrete is stabilized and lifted to the proper position, the injection holes are filled with new cement, allowing you to use your surface immediately.
Polyurethane concrete raising uses a foam material that is injected under the slab. When the components of the material are mixed, a reaction causes the material to expand. This expanded foam fill any voids beneath the slab and raises the concrete. This material will never lose density, is permanent and weighs only about 2 pounds per cubic foot.
