Bring Back the Safety and Curb Appeal of Your Front Porch
If your porch is settling, cracking, or pulling away from your steps or home, we can help. A sunken porch can lead to water drainage problems, trip hazards, and long-term structural issues. At RaiseRite, we lift and stabilize sunken porches using high-density polyurethane foam. It’s clean, fast, and done without the need for demolition or replacement.
Why Do Porches Sink?
Concrete porch slabs are often built on fill soil that settles over time. Water from downspouts, shifting ground, or seasonal freeze-thaw cycles can cause that soil to compress or wash away. The result: your porch dips, tilts, or separates from the house — creating gaps, cracks, and uneven transitions between your steps and entryway.
We also level driveways, garage floors, walkways, steps, patios, slabs, interior floors, and pool decks. See all residential concrete leveling services here.

What Are the Signs You Need Porch Leveling?
Sinking porches are more than a cosmetic issue. They affect safety and structure. Watch for:
Gaps between the porch and front steps or doorway
Porch pulling away from the house
Water running toward your foundation
Uneven or cracked slabs
Soft spots or hollow sounds when walking across the porch
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.
Frequently Asked Questions

We also level concrete steps and can raise both the steps and porch in the same visit.
It usually will. Once lifted, the porch realigns to eliminate gaps and restore a level surface at the entry point.
Yes — re-leveling the porch can correct slope and drainage issues that cause water to flow toward the house.

In most cases, yes. Leveling is faster, cleaner, and far more affordable than full concrete removal and repouring.
