How foam mudjacking works
Foam concrete lifting (you'll hear it called foam mudjacking, polyjacking, or poly leveling — same thing) injects a two-part polyurethane through ports about the size of a dime. The foam expands under the slab, fills voids, and lifts with surgical control. It reaches full strength in about 15 minutes, weighs a fraction of slurry, and the patched ports all but disappear.
Where we recommend foam in St. Joe
- Garage and interior floors — small ports, no mess indoors
- Pool decks — light material, gentle on plumbing and coping
- Porches and stoops on questionable footings — minimal added weight
- Jobs that need same-hour use or precise fractional lifts
For very large loess washout voids, slurry mudjacking is often the more economical fill — see our honest comparison. Plenty of St. Joseph jobs get the best result from foam; plenty get the same lift from slurry for less. We quote what fits.
Common questions
Is foam concrete lifting permanent?
Yes — cured polyurethane is inert, waterproof, and doesn't break down in soil. Like any lift, longevity depends on keeping water from re-eroding the base, which is why we seal joints after lifting.
How soon can I use the slab?
About 15 minutes after the lift — foam cures almost immediately.
Is foam safe for yards and pets?
Once cured (minutes), the foam is inert and safe.
