Get matched with top concrete mudjacking pros in Prien, LA

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.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

The average cost of mudjacking is around $5 per square foot of concrete, with most concrete leveling jobs totaling between $3 and $8 per square foot. The typical cost to fix a sinking portion of concrete slab with mudjacking is around $1,100. The price you’ll pay depends on the size of the concrete slab you need to be leveled, the accessibility of the slab, and the type of material your contractor uses beneath the concrete to lift it back into place.

Mudjacking can take 24 to 72 hours to cure enough to resume normal use. Because the slurry mixture contains cement, it needs to fully harden to ensure that added weight won’t shift the concrete slab before it has completely set. Your concrete contractor will be able to tell you when you’re free to use your concrete surfaces again after mudjacking.
