THE PROBLEM
A homeowner in Sherman noticed the concrete patio beneath their backyard shed had begun settling unevenly. One side of the slab had dropped several inches, causing the shed to lean slightly and creating concerns about long-term stability.
The settlement also allowed rainwater to collect around the patio, increasing the risk of additional soil erosion beneath the slab.
Like many properties in North Texas, the changing clay soil beneath the patio had expanded and contracted over time, leaving unsupported voids below the concrete.
The homeowner wanted a solution that would:
- Lift and level the shed patio
- Stabilize the soil beneath the slab
- Help protect the shed from further movement
- Improve drainage around the structure
- Avoid removing and replacing the concrete
OUR 3-STEP CONCRETE LIFTING PROCESS

1 Drill
Small, strategically placed holes were drilled into the patio slab to access the voids beneath the concrete.
2 Pump
High-density polyurethane foam was injected underneath the patio. As the foam expanded, it filled empty spaces, strengthened the supporting soil, and carefully lifted the slab back toward its proper position.
3 Patch
Once the patio was level and stable, the drill holes were patched neatly, leaving the surface clean and ready for immediate use.
Because only small holes are required, the repair was completed with minimal disruption to the surrounding yard.
THE RESULT
In just a few hours, the shed patio was restored to a stable, level condition.
The slab once again provided solid support for the shed, while improved drainage helped reduce the risk of future erosion beneath the concrete.
The homeowner avoided the cost and inconvenience of replacing the patio and moving the shed.
Benefits of the repair included:
- Level, stable patio surface
- Improved support beneath the shed
- Better drainage around the slab
- No demolition or concrete replacement
- Ready to use immediately after completion

WHY SHED PATIOS SETTLE IN SHERMAN
Concrete patios beneath sheds often settle because of soil movement, erosion, and poor compaction beneath the slab. Sherman experiences significant moisture changes throughout the year, causing clay soils to repeatedly expand and shrink.
As the supporting soil shifts, voids can develop beneath the concrete, allowing the patio to settle unevenly. Heavy shed loads can make the problem even more noticeable over time.
Polyurethane foam lifting fills these underground voids while stabilizing the soil and restoring the patio to a safer, more level position.
A SMARTER ALTERNATIVE TO REPLACEMENT
- Costs significantly less than replacing the patio
- Most projects are completed in just a few hours
