Belvidere, Boone County
Foam Injection (Polyjacking) in Belvidere, IL
Belvidere is the one town on this list in Boone County rather than Winnebago, and it has an older housing stock than the Rockford suburbs north of it. Older stock means more original walks and stoops still in place, and those are the slabs most likely to have dropped far enough to be a genuine hazard rather than an annoyance.

What Belvidere Concrete Is Like
A denser grid than the outer villages, with more homes close to the public sidewalk. That proximity is what turns a settled walk into a liability question rather than only a cosmetic one, because the walk in front of a house is the one a stranger uses.
This page is about the method itself: foam is usually the better call wherever water is the actual cause, which on the evidence of this site's own town pages is most of the time.
Cause
Why It Drops
- The two-part polyurethane expands as it reacts, filling the void and lifting the slab without the added weight a slurry carries.
- It cures chemically within minutes, which is why a foam-lifted driveway can be driven on the same morning rather than waiting out the day.
- The holes are roughly the size of a penny, smaller than mudjacking needs, because the foam does not require the same bore to flow.
- It does not wash out, so where the original void was caused by moving water, foam stays where it was injected instead of eroding the same way the soil did.
All of it sits on the same underlying fact: Rockford requires frost footings at 42 inches because the ground here freezes that deep, and a foam injection (polyjacking) slab is poured well above that line. See why concrete sinks in Rockford.

Straight answer
When Not to Lift It
Foam is not worth the extra cost on a large, stable slab that settled once years ago and has not moved since, where mudjacking's lower price and comparable 5-to-10-year life cover the job just as well. Paying foam prices everywhere is not the honest answer any more than mudjacking everywhere is.
