Get matched with top concrete mudjacking pros in Hindman, KY

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Polyjacking and mudjacking can both be good solutions to sinking concrete, depending on your situation. Polyjacking, which uses expanding polyurethane foam to lift concrete, is a better option than mudjacking because the foam weighs less and won’t contribute to additional sinking. Polyjacking can be a suitable solution for any sinking concrete slab, while mudjacking is normally only a good option for non-structural concrete, like sidewalks, patios, pool decks, and concrete driveways. However, polyjacking costs much more—as much as $25 per square foot, compared to the maximum of $6 per square foot you’d pay for mudjacking.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.
