Polyjacking is the modern successor to mudjacking. A two-part polyurethane foam is injected under the sunken slab, expands within seconds, fills the voids, compacts loose soil, and lifts the slab back to level in small, controlled increments.
Polyjacking quotes in Peoria: (309) XXX-XXXX
Why homeowners choose foam
- Same-day use. Drive on the slab 15 to 30 minutes after the lift.
- Waterproof. The cured foam does not erode, dissolve or wash out, whatever Peoria’s spring rains and freeze-thaw winters do to the soil around it.
- Small holes. Injection ports are about 5/8 inch, nearly invisible after patching. Mudjacking holes are two to three times larger.
- Lightweight. Lifting foam weighs a few pounds per cubic foot; cement slurry weighs many times more. On soil that has already failed once, the lighter fill adds almost no new load.
- Precision. Expansion is controlled in small shots, which matters where an exact final height counts: pool decks, thresholds, sidewalk joins.
Why foam suits Central Illinois ground
Central Illinois works against soil-based fills. Clay that shrinks in dry summers and swells in wet springs keeps the ground under a slab moving, and every freeze-thaw winter pumps water beneath the concrete, then washes fines out through the thaw. Foam sidesteps both problems: the spring melt cannot erode a waterproof fill, and the light weight matters on soil that has already proven it will compress. On lots where a downspout has washed out the base once, that combination is usually what tips our quote toward foam.
What is better, mudjacking or polyurethane?
| Polyjacking | Mudjacking | |
|---|---|---|
| Fill material | Expanding polyurethane foam | Cement and sand slurry |
| Hole size | About 5/8” | About 1–2” |
| Cure time | About 15 minutes | About 24 hours |
| Water resistance | Waterproof | Can erode over decades |
| Weight on soil | Very light | Heavy |
| Price | Moderate | Lowest |
| Best for | Patios, pool decks, garage floors, precision lifts, poor soil | Large heavy slabs, big voids, budget jobs |
Both methods work. We quote whichever fits your slab, soil and budget, and on some jobs we use foam for the patio and slurry for the driveway in the same visit.
