Patio Lifting & Leveling in St. Louis, MO
Is Your Patio Sinking or Pulling Away From the House?
A sunken patio can create uneven walking surfaces, low spots that collect water, and noticeable gaps where the concrete meets your home, steps, or surrounding slabs.
St. Louis Mudjacking lifts settled patio concrete using a proven grout-based mudjacking process. When the existing concrete is still in good condition, lifting may help restore a more even surface without tearing out and replacing the entire patio.

Why Do Concrete Patios Sink?
Most patio settlement starts underneath the concrete.
A patio slab depends on the soil beneath it for support. When that soil settles, washes away, or changes with moisture, sections of the concrete can begin to drop.
Common causes include:
- Soil settlement beneath patio slabs
- Poorly compacted fill from original construction
- Clay soil movement as moisture levels change
- Water washout beneath the concrete
- Drainage problems around the patio
- Downspout runoff near slab edges
- Freeze-thaw cycles that contribute to soil movement
- Voids beneath the slab that leave sections unsupported
These conditions are common around St. Louis, where clay-heavy soil, changing moisture levels, heavy rain, and seasonal temperature changes can all affect concrete.
Settlement may also affect nearby surfaces. We can help with Sidewalk & Walkway Lifting, Steps & Entry Lifting, and Concrete Slab Lifting.
Signs Your Patio May Need Leveling
Patio settlement can develop slowly, especially when only one section of the slab begins to move.
Watch for:
- One patio slab sitting lower than the next
- Raised edges that create trip hazards
- Water collecting in low areas after rain
- Concrete sloping toward the house
- Gaps forming between the patio and foundation
- Uneven transitions near doors or steps
- Patio furniture sitting unevenly
- Cracks forming near settled slab joints
- Hollow or unsupported areas beneath the concrete
- Sections of the patio noticeably dropping over time
If the concrete is still solid but has simply settled, mudjacking may be an option.
Our 3-Step Mudjacking Process
How Patio Mudjacking Works
Patio lifting uses a straightforward three-step process to restore support beneath the slab and carefully raise settled concrete.
Drill & Prepare
Access holes are drilled through the patio slab in locations that allow us to reach unsupported areas beneath the concrete.
Pump & Level
A grout-based mudjacking mixture is pumped beneath the slab. The material fills voids while controlled pressure gradually raises the patio toward the proper position.
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 Patio
If your patio concrete is still in good condition, lifting it can provide several practical benefits.
- Reduce trip hazards caused by uneven slab edges
- Improve drainage by correcting certain low or poorly sloped areas
- Create a more usable surface for tables, chairs, and outdoor activities
- Improve transitions near doors, steps, and neighboring concrete
- Save usable concrete instead of automatically replacing it
- Lower disruption compared with full tear-out and replacement
- Potentially reduce repair costs when lifting is a suitable option
- Improve the appearance of visibly settled patio sections
Mudjacking will not make old concrete look brand new, but it can help restore the position and usability of a patio slab that is still worth saving.

Patio Lifting FAQs
Frequently Asked Questions
Yes, many settled patios can be lifted when the concrete itself is still structurally sound. Mudjacking fills unsupported areas beneath the slab and uses controlled pressure to raise the concrete.
Settlement near the house can happen when soil compacts, fill material settles, or water moves through the soil beneath the slab. Drainage and downspout runoff can also contribute to loss of support.
In some cases, yes. If settlement has caused the patio to slope toward the home, lifting certain sections may help improve the grade. The amount of correction depends on the slab and surrounding conditions.
Mudjacking is designed to lift and support settled concrete. It does not erase existing cracks. Raising the slab may improve alignment, but visible cracks can remain afterward.
If the concrete is still solid and the main problem is settlement, lifting may make sense. Concrete that is badly cracked, crumbling, or deteriorated may be a better candidate for replacement.
Often, yes. Patio slabs near steps and entry areas can sometimes be lifted, but the surrounding concrete and elevations need to be considered carefully. We also provide Steps & Entry Lifting when nearby concrete has settled.
Depending on the situation, material can be placed beneath unsupported concrete to help fill voids. Learn more about Void Filling.
The access holes are patched after the work is complete. The patches may remain visible, particularly on older or weathered concrete.
The time depends on the size of the patio, how much it has settled, and the conditions beneath the slab. Smaller projects may be completed relatively quickly, while larger or more complicated patios can take longer.
