URL: https://concretelevelingctpro.com/faq/ Answers # Concrete Leveling Questions, Answered Straight The questions we get asked before people book, with the answers we'd give you on the phone. If yours isn't here, call and ask. ## How the Work Is Done ### How does polyurethane concrete leveling work? expand\_more We drill penny-sized (5/8") ports through the settled slab, inject a two-part expanding polyurethane that fills the void beneath it, and lift the concrete back to grade in monitored increments. The foam reaches most of its strength in 15-30 minutes, then the ports are patched. There's no demolition and your landscaping stays where it is. ### How soon can I drive or walk on the concrete again? expand\_more Same day on most residential jobs. The polyurethane reaches load-bearing strength within 15-30 minutes of injection, so a driveway or garage floor typically takes a vehicle before we leave the property. Mudjacking slurry, by comparison, needs 24-72 hours before it will carry a load. ### How is this different from mudjacking? expand\_more Mudjacking pumps a cement slurry weighing roughly 120 lbs per cubic foot onto ground that has already failed under the slab's own weight, through 2-3 inch holes. Polyurethane foam weighs 2-6 lbs per cubic foot, goes in through 5/8-inch ports, cures in minutes rather than days, and is hydrophobic so it doesn't wash out over time. ### Will the work damage my landscaping or driveway surface? expand\_more No. The equipment works from the slab surface, so there's no excavator, no demolition and no material stockpiles across the lawn. The only marks left are the patched injection ports. This is the main practical reason homeowners choose lifting over replacement on a property they've spent years landscaping. ### Can commercial work be done outside our trading hours? expand\_more Yes. Commercial slab work is scheduled around tenant and trading hours, including evenings and weekends. Work areas are sectioned so the rest of the site keeps operating, and because the foam cures in minutes rather than days, an entrance or loading area usually reopens the same shift. ## Cost & Quoting ### How much does concrete leveling cost in Connecticut? expand\_more Every job is quoted per project on square footage, lift height and how much void has to be filled. Flat per-slab rates hide too much variation to be honest. What holds across jobs is that lifting runs at a fraction of tear-out and replacement. The on-site inspection and written quote are free, and the quote is the price. ## Is My Slab a Candidate? ### How do I know if my slab can be lifted or needs replacing? expand\_more Intact sections with clean cracks lift well. Slabs that are spalling, crumbling, or broken into many pieces have reached the end of their service life and are better replaced. We give you that answer at the free inspection in writing, including when replacement is the better buy, because a lift on a failing slab isn't worth your money. ### Can stamped or decorative concrete be lifted? expand\_more Yes, and it's one of the strongest cases for lifting. Ports are placed in grout lines and pattern joints, then patched and color-matched. If a stamped patio is torn out, matching the original pattern and color is difficult and often impossible, so preserving the surface usually settles the decision on its own. ## General Questions ### Why does concrete sink so much in Connecticut? expand\_more Connecticut's frost line sits at 42 inches, and footings must reach below it. Driveways, patios and walkways sit well above that depth and take the full freeze-thaw cycle every winter. Combine that with the uncompacted backfill most flatwork was poured over and water washing fines out from underneath, and a void forms. The slab has nothing left to sit on, so it drops. ### Does homeowners insurance cover sunken concrete? expand\_more Usually not. Gradual settlement is typically excluded as wear and maintenance rather than a covered sudden loss. Liability coverage is a separate question. If someone trips on a walkway hazard you knew about, that's where the exposure sits, which is why fixing a known trip hazard is cheaper than the claim. ### Are you licensed and insured? expand\_more Yes. We hold Connecticut Home Improvement Contractor registration with the CT Department of Consumer Protection, which is required for residential work in this state, and carry general liability insurance. Our registration number is in the site footer. Ask any contractor for theirs before they start work on your property. ## Service Area ### Do you serve West Hartford and the Farmington Valley? expand\_more Yes. We work throughout Hartford County from our Berlin base. West Hartford and Glastonbury are roughly 12-14 miles out, Avon and Simsbury 20-plus. Those towns get the same crew and the same scheduling; the older housing stock around West Hartford Center and Bishop's Corner in particular sees a lot of driveway and walkway settlement. ## Want the Longer Version?
