Why Concrete Settles in McHenry
- Water runoff and erosion from frequent rainfall or poor drainage
- Expansive clay soil that shifts with moisture changes
- Improper soil compaction when concrete was originally poured
- Frost heave from repeated freeze-thaw cycles
- Tree roots or organic breakdown beneath slabs
These issues result in voids beneath the concrete, causing it to crack, tilt, or sink. If not addressed, it may worsen — becoming more costly and hazardous.
PolyLevel® vs. Mudjacking: What’s Better?
Mudjacking involves pumping a heavy cement slurry beneath the slab. But this adds weight to already unstable soil — often causing more long-term problems. In contrast, PolyLevel® foam is lightweight, expands with precision, and cures in just 15 minutes.
Benefits of PolyLevel® for McHenry Homes:
- Small, clean injection holes
- Minimal disruption to landscaping or hardscapes
- Fast-curing foam – walk on it within 30 minutes, drive on it within 4 hours
