Eliminate Trip Hazards on Steps
Sunken or uneven concrete steps can quickly become a safety hazard around your home or property. When steps settle or shift, they create uneven heights between stair sections, increasing the risk of trips and falls. Over time, this can also lead to cracking and additional structural movement.
Saint Louis Polyjack provides concrete step leveling using advanced polyurethane foam injection. Our process lifts and stabilizes sinking concrete from underneath—no demolition or replacement—often saving customers up to 50%. Most repairs can be completed in just a few hours, and the steps are typically ready to use the same day.
Why Concrete Steps Sink
Concrete steps rely on the soil beneath them for support. When that soil shifts, erodes, or settles, the steps above can begin to sink or tilt.
Common causes include:
- Soil erosion caused by water runoff
- Voids forming beneath the steps
- Poor soil compaction during installation
- Freeze and thaw cycles affecting the soil
- Natural ground settling over time
When these issues occur, the steps lose support underneath. Concrete leveling restores that support by filling the voids and stabilizing the soil beneath the steps.
Signs Your Concrete Steps Need Leveling
Step settlement often happens slowly, which means many property owners do not notice the problem until the steps become uneven or unsafe.
You may need step leveling if you notice:
- Uneven step heights
- Steps tilting away from the porch or entryway
- Gaps forming between steps and surrounding concrete
- Cracks appearing in the stair structure
- Water pooling near the base of the steps
- A noticeable shift between stair sections
If these issues continue to worsen, the steps may settle further and become more dangerous to use.
Sometimes sinking steps are connected to other concrete problems around the home. If multiple surfaces are settling, Saint Louis Polyjack also repairs walkway and sidewalk leveling, driveway leveling, and porch leveling. In some cases, soil movement may also create empty spaces beneath the slab, which can be stabilized through void filling.

Our Fix: Polyurethane Step Leveling
Saint Louis Polyjack uses a polyurethane foam injection process to lift and stabilize concrete steps safely and efficiently. Instead of tearing out and rebuilding the stairs, our method restores support beneath the structure by filling hidden voids and strengthening the soil underneath.
Our process works in three simple steps:
1. Drill Small Access Holes
Small holes are drilled in precise areas so we can reach the empty space beneath the steps.
2. Inject Expanding Polyurethane Foam
High-density foam is injected beneath the structure. The material expands to fill voids, stabilize the soil, and gently lift the steps back into position.
3. Patch the Holes and Finish the Repair
Once the steps are level, the drill holes are patched neatly. Most steps are ready to use shortly after the repair is completed.
Benefits of Step Leveling
Concrete lifting offers several advantages compared to rebuilding or replacing concrete steps.
Some of the main benefits include:
- Save up to 50% compared to replacement
- Fast repair that usually takes only a few hours
- Minimal disruption to surrounding landscaping
- Long-lasting stabilization beneath the steps
- Improved safety for entrances and walkways
- Elimination of uneven step heights
Instead of demolishing the stairs, leveling restores the existing concrete while correcting the problem underneath.

FAQs – Concrete Step Leveling
Clear answers about safety, repair methods, and how concrete lifting restores uneven steps.
Yes. If the steps are structurally sound, polyurethane lifting can raise and stabilize them without demolition. You can learn more about how this works on our concrete leveling process page.
Most concrete step leveling repairs are completed in just a few hours, making it much faster than rebuilding the stairs.
Concrete steps are typically ready to use the same day because the polyurethane foam cures quickly and provides strong support beneath the structure.
Steps usually settle due to soil erosion, voids beneath the structure, or natural ground movement. In some cases, stabilizing the area with void filling can help restore proper support.
Many property owners choose polyurethane leveling because it uses smaller drill holes and lightweight material that stabilizes the soil beneath the steps. You can read more about the difference on our poly leveling vs mudjacking page.
Yes. The same lifting process can repair driveways, walkways and sidewalks, garage floors, and pool decks if they are sinking or uneven.
