Sidewalk & Walkway Lifting in St. Louis, MO
Is Your Sidewalk Sinking or Creating a Trip Hazard?
An uneven sidewalk can turn a normal walking path into a safety problem. One settled slab may leave a raised edge, low spot, or awkward transition that people have to step over every time they use the walkway.
St. Louis Mudjacking lifts settled sidewalk and walkway concrete using a proven grout-based mudjacking process. When the existing concrete is still in good condition, lifting it may help restore a safer, more even walking surface without tearing out and replacing the entire section.

Why Do Concrete Sidewalks and Walkways Sink?
Most sidewalk settlement begins with a loss of support beneath the concrete.
When the soil under a walkway compacts, shifts, or washes away, part of the slab can begin to drop. Because sidewalks are made up of separate sections, even a small amount of settlement can create a noticeable height difference between adjoining slabs.
Common causes include:
- Soil settlement beneath sidewalk slabs
- Poorly compacted fill from construction or previous excavation
- Clay soil movement as moisture levels change
- Water washout that removes support beneath the concrete
- Drainage problems near walkways and landscaping
- Freeze-thaw cycles that contribute to movement below the slab
- Tree roots and landscaping changes that affect surrounding soil
- Voids beneath the concrete that leave sections unsupported
These conditions are common throughout the St. Louis area, where clay-heavy soils, changing moisture levels, heavy rain, and seasonal temperature swings can all affect concrete.

Signs Your Sidewalk May Need Leveling
Sidewalk settlement is often easy to notice because you walk over the same area regularly.
Watch for:
- One sidewalk section sitting lower than the next
- Raised edges between adjoining slabs
- A noticeable trip hazard along a walkway
- Water collecting in low sections
- Concrete sloping toward the house or another structure
- Gaps between sidewalk slabs
- Uneven transitions where a walkway meets steps or a driveway
- Sections that rock or move when stepped on
- Hollow areas beneath the concrete
- Walkways that have become difficult for carts, strollers, or mobility devices to cross
If the concrete itself is still solid and the main problem is settlement, mudjacking may be an option.
Our 3-Step Mudjacking Process
How Sidewalk & Walkway Mudjacking Works
Sidewalk lifting uses a straightforward three-step process to restore support beneath settled concrete and carefully bring uneven slabs closer to the proper level.
Drill & Prepare
Access holes are drilled through the settled sidewalk slab in locations that allow us to 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 settled sidewalk section.
Patch & Finish
Once the slab has been lifted, 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 Sidewalk
When the existing concrete is still worth saving, lifting a settled sidewalk can provide several practical benefits.
- Reduce trip hazards caused by raised slab edges
- Create smoother walking transitions between concrete sections
- Improve accessibility along frequently used walkways
- Help correct certain drainage problems caused by low areas
- Save usable concrete instead of automatically replacing it
- Reduce disruption compared with tearing out entire sidewalk sections
- Potentially lower repair costs when mudjacking is a suitable option
- Improve the appearance of visibly uneven walkways
Mudjacking will not erase existing cracks or make older concrete look new, but it can help restore the position and usability of slabs that are still in good condition.

Sidewalk & Walkway Lifting FAQs
Frequently Asked Questions
If the slab is still solid but has settled lower than the surrounding concrete, it may be a good candidate for mudjacking. Concrete that is badly cracked, crumbling, or deteriorated may be better suited for replacement.
Mudjacking can often reduce a trip hazard when it is caused by one concrete section settling lower than the slab next to it. The goal is to raise the settled section and improve the transition between slabs.
The soil beneath that section may have settled, compacted, or washed away. Because each sidewalk slab can move independently, one section may drop while the surrounding slabs remain in place.
In many cases, yes. Sidewalks and driveway slabs often settle in the same areas because they are affected by similar soil and drainage conditions. See our Driveway Leveling service for related driveway problems.
Mudjacking is performed through access holes in the concrete, so it generally requires less demolition than replacing sidewalk slabs. Every property is different, and we work carefully around nearby landscaping and structures.
It depends on how many slabs need to be lifted and the conditions beneath them. Smaller walkway projects may be completed relatively quickly, while larger or more complicated areas can take longer.
The access holes are patched when the lifting is finished. The patches can remain visible, particularly on older or weathered concrete, but they are kept as neat as possible.
Yes, depending on the condition of the concrete. Walkways near entrances often settle along with steps, porches, or adjoining slabs. Learn more about Steps & Entry Lifting if the problem extends into your entrance area.
No concrete lifting contractor can guarantee that soil will never move again. Mudjacking restores support and raises the existing slab, but future drainage, soil movement, or changing ground conditions can still affect concrete over time.
When the slab is a good candidate for lifting, mudjacking avoids removing and replacing the entire section. That can mean less demolition, less disruption around the property, and a faster repair process than full replacement.
