Fix Uneven Sports Courts Without Replacement
Uneven concrete on sport courts can quickly become a safety issue. When slabs settle or shift, they create uneven playing surfaces that can increase the risk of slips, trips, and injuries. Courts that are no longer level can also affect how balls bounce and how the surface performs during games.
Why Sport Court Concrete Sinks
Sport courts are built on concrete slabs that depend on stable soil underneath. Over time, soil movement, erosion, and moisture changes can cause the ground beneath the slab to shift.
Common causes include:
- Soil erosion caused by water runoff
- Voids forming beneath the concrete slab
- Poor soil compaction during construction
- Drainage issues around the court
- Seasonal expansion and contraction of soil
When the soil loses stability, the concrete slab begins to settle or tilt. Concrete leveling restores support beneath the court by filling these empty spaces and stabilizing the soil.
Signs Your Sport Court Needs Leveling
Settlement can occur gradually, which means the playing surface may become uneven before the problem is clearly visible.
You may need sport court leveling if you notice:
- Uneven areas across the court surface
- Trip hazards between sections of concrete
- Slabs sitting lower than surrounding areas
- Cracks forming in the concrete surface
- Water pooling on the court after rain
- Inconsistent ball bounce during play
If these problems continue to worsen, the court surface may become unsafe for players and visitors.
Sometimes settlement on sport courts occurs alongside other concrete issues on the property. Saint Louis Polyjack also provides leveling for parking lots, warehouse floors, and interior concrete floors. If soil erosion has created empty spaces beneath the slab, void filling can help restore support beneath the concrete.

Our Fix: Polyurethane Sport Court Leveling
Saint Louis Polyjack uses a polyurethane foam injection process to lift and stabilize sport court concrete safely and efficiently. Instead of removing and replacing the concrete surface, our method restores support beneath the slab by filling hidden voids and strengthening the soil underneath.
Our process works in three simple steps:
1. Drill Small Access Holes
Small holes are drilled in specific locations of the slab so we can reach the empty space beneath the court.
2. Inject Expanding Polyurethane Foam
High-density polyurethane foam is injected beneath the concrete. The material expands to fill voids, stabilize the soil, and gently lift the slab back into position.
3. Patch the Holes and Finish the Repair
Once the court is level, the drill holes are patched neatly. Most sport courts are ready to use shortly after the repair is completed.
Benefits of Sport Court Leveling
Concrete lifting offers several advantages compared to replacing the entire court.
Some of the main benefits include:
- Save up to 50% compared to replacing the slab
- Minimal disruption to surrounding areas
- Long-lasting stabilization beneath the concrete
- Improved drainage across the court surface
- Fast repairs with minimal facility downtime
- Safer, more consistent playing conditions
Instead of demolishing the court, leveling restores the existing concrete while correcting the problem underneath.
