Concrete Leveling Process in St. Louis, MO
Sinking or uneven concrete is a common problem for homes and commercial properties across the St. Louis area. Over time, soil can settle, wash away, or shift beneath concrete slabs. When the ground underneath loses support, the concrete begins to sink or tilt.
Saint Louis Polyjack uses a proven polyurethane foam concrete lifting process to raise and stabilize sinking concrete without the need for demolition or replacement. This method restores the slab from underneath while addressing the voids and weak soil that caused the problem in the first place.
Our process is fast, clean, and designed to deliver long-lasting results.
Why Concrete Sinks
Concrete slabs are heavy, but they rely on the soil beneath them for support. When that soil changes, the slab can settle.
Some of the most common causes of sinking concrete include:
- Soil erosion from water runoff
- Poor soil compaction during construction
- Voids forming beneath the slab
- Seasonal soil expansion and contraction
- Drainage problems around the property
When these issues occur, empty spaces can develop beneath the concrete. Without support, the slab begins to sink.
Concrete lifting addresses this problem by filling those voids and restoring support below the surface.
Our Polyurethane Concrete Lifting Process
Our three-step polyurethane lifting process that repairs concrete safely and efficiently.
Step 1
Drill Small Access
Holes
We begin by drilling small holes in the affected concrete slab. These holes allow us to reach the empty space beneath the concrete where support has been lost.
The holes are small and carefully placed so the repair remains clean and minimally invasive
Step 2
Inject Expanding Polyurethane Foam
Next, we inject high-density polyurethane foam beneath the slab through the drilled holes.
As the material expands, it:
- Fills hidden voids beneath the concrete
- Stabilizes weak soil
- Lifts the slab back toward its original level
The lifting process is controlled and precise. Our technicians monitor the slab carefully during injection to ensure the concrete is raised evenly and safely.
Step 3
Patch the Holes & Clean the Area
Once the slab is properly leveled, we patch the small drill holes neatly. The repaired surface blends with the surrounding concrete and remains structurally sound.
Most projects are completed in just a few hours, and the surface is typically ready to walk or drive on the same day.
Advantages of PolY FOAM CONCRETE LEVELING
Poly foam concrete lifting has become one of the most effective ways to repair sinking concrete. Some of the key benefits include:
- Faster than replacing concrete
- Minimal disruption to the property
- Clean and precise repair process
- Lightweight material that does not overload the soil
- Long-lasting support beneath the slab
- Save 50% compared to full concrete replacement
Because the foam expands beneath the slab, it fills spaces that traditional repair methods may not reach.
Where Concrete Leveling Works
Polyurethane lifting can be used on many types of concrete surfaces.
Common applications include:
- Driveways
- Sidewalks and walkways
- Garage floors
- Patios and porches
- Pool decks
- Concrete steps
- Interior concrete slabs
- Warehouse and commercial floors
- Parking lots and entryways
If the concrete is structurally sound but has settled due to soil movement, lifting is often a practical solution.
