Porch Lifting & Leveling in St. Louis, MO
Is Your Concrete Porch Sinking or Pulling Away?
A sunken porch can create an uneven entry, noticeable gaps, drainage problems, and trip hazards right where people enter your home. In some cases, the porch slab may also begin pulling away from steps, walkways, or the foundation.
St. Louis Mudjacking lifts settled porch concrete using a proven grout-based mudjacking process. When the slab is still structurally sound, lifting it may help restore a safer, more even entry without tearing out and replacing the entire porch.

Why Do Concrete Porches Sink?
Porch settlement usually starts with a loss of support beneath the concrete.
The soil or fill beneath a porch can compact, wash away, or shift over time. Once empty spaces develop beneath the slab, sections of the porch may begin to drop.
Common causes include:
- Poorly compacted fill beneath the original porch
- Soil settlement around the home
- Clay soil movement as moisture levels change
- Water washout beneath the concrete
- Drainage problems near the porch or foundation
- Freeze-thaw cycles that contribute to soil movement
- Voids beneath the slab that leave sections unsupported
- Backfilled soil settling near the foundation over time
These conditions are common throughout the St. Louis area, where clay-rich soil, heavy rain, changing moisture levels, and winter temperature swings can all affect concrete.
If settlement is also affecting nearby areas, we can help with Steps & Entry Lifting, Sidewalk & Walkway Lifting, and Concrete Slab Lifting.
Signs Your Porch May Need Leveling
Porch settlement can develop gradually, so small changes around the entry are worth paying attention to.
Watch for:
- One side of the porch sitting lower than the other
- A noticeable slope across the concrete
- Gaps forming between the porch and nearby steps
- Concrete pulling away from the house or foundation
- Raised edges that create a trip hazard
- Water collecting in low areas
- Water draining toward the home instead of away
- Uneven transitions between the porch and walkway
- Hollow or unsupported areas beneath the slab
- Doors or entry areas feeling noticeably uneven nearby
If the porch concrete is still solid but has simply settled, mudjacking may be an option.
Our 3-Step Mudjacking Process
How Porch Mudjacking Works
Porch lifting uses a straightforward three-step process to restore support beneath the concrete and carefully raise settled sections.
Drill & Prepare
Access holes are drilled through the porch slab in carefully selected locations so we can reach the unsupported areas underneath.
Pump & Level
A grout-based mudjacking mixture is pumped beneath the concrete. The material fills voids while controlled pressure gradually raises the porch toward the proper level.
Patch & Finish
Once the lifting is complete, the access holes are patched and the work area is cleaned up.
Learn more about the method on our Concrete Lifting & Mudjacking page.
Benefits of Lifting a Sunken Porch
If the porch slab is still in good condition, lifting it can provide several practical benefits.
- Reduce trip hazards around the main entry
- Improve porch-to-step transitions between adjoining concrete surfaces
- Help correct certain drainage problems caused by low areas
- Restore a more even entry surface for everyday use
- Save usable concrete rather than automatically replacing it
- Reduce disruption compared with full demolition and replacement
- Potentially lower repair costs when mudjacking is a suitable option
- Improve curb appeal by correcting visibly settled concrete
Mudjacking will not make worn or stained concrete look new, but it can help restore the position and usability of a porch slab that is still worth saving.

We keep concrete lifting straightforward.

Not every driveway should be lifted. If the concrete is badly broken or deteriorated, replacement may be the better answer. We would rather tell you that upfront.
Porch Lifting FAQs
Frequently Asked Questions
If the concrete is still solid but has settled lower than nearby surfaces, it may be a good candidate for mudjacking. Concrete that is badly cracked, crumbling, or deteriorated may be better suited for replacement.
Mudjacking may be able to improve certain porch slopes by raising settled sections. The amount of correction depends on the condition of the slab, surrounding concrete, and how much movement has occurred.
The soil or fill beneath the porch may have settled while the home remained in place. This can cause the slab to drop and create a visible gap near the foundation or entry.
In some situations, multiple adjoining concrete sections can be addressed as part of the same project. If the steps have also settled, see our Steps & Entry Lifting service.
The goal is to raise the concrete gradually and in a controlled manner. We consider the surrounding structure and adjoining surfaces before and during the lifting process.
Project time depends on the size of the porch, the amount of settlement, access, and the number of areas that need lifting.
The access holes are patched once lifting is complete. The patches may remain visible, particularly on older concrete, but they are kept as neat as possible.
If pooling is being caused by a settled section of concrete, lifting may improve the slope and drainage. Other drainage problems may have causes that concrete lifting alone cannot correct.
Settled walkways can often be evaluated along with the porch. Our Sidewalk & Walkway Lifting service covers adjoining pedestrian areas.
That depends on the condition of the concrete. When the slab is still structurally sound, mudjacking may allow you to keep the existing porch with less disruption than full replacement.
