What Causes Slab Damage in Charlotte?
- Expansive Clay Soil: Expands with rain, shrinks in drought → causes cracking.
- Poor Drainage: Standing water erodes soil under slabs.
- Heavy Loads: Driveways or garages exposed to excess weight.
- Improper Installation: Poor compaction leads to voids under the slab.
- Age & Weather: Freeze-thaw cycles and long-term settling.
Concrete Slab Repair Methods Explained
- Crack Injection: Epoxy/polyurethane seals small cracks, preventing water intrusion.
- Slab Leveling (Mudjacking/Polyjacking): Material pumped under slab to lift and stabilize it.
- Slab Reinforcement: Steel piers or helical piers installed to stabilize sinking slabs.
- Full Replacement: Old slab removed and rebuilt when repairs won’t suffice.
