Repair your sidewalks with poly foam injections
Trip hazards are a safety problem whether at home in the neighborhood, or in a commercial setting.
Uneven concrete isn't just a small pain. It can actually cost you your homeowners insurance. Any lift over 1/4" is considered a trip hazard. If someone trips over a trip hazard on your property you could be liable!
Poly foam injections will raise and level your current walkway back to even.
