"WOW! Groundworks is a great, reliable company! We had the dream team, Ryan, Alejando (Alex) and Jose, working on our home. Ryan kept us informed on what was going on the during the whole project. Ryan and Alex were so reassuring of all our fears and concerns, we knew we were in good hands. Alex and Jose were so polite and talk about hard working!! All three of them went above and beyond, exceeding our expectations, saving some landscaping we didn't expect to be saved. They took great care with our landscaping and yard and did not cause any unexpected damage to any of it! They did a great job with the clean-up at the end of the job as well. These three men worked great together as a team. We were happy to see them everyday and a little sad when we said good bye."
Concrete Mudjacking questions, answered by experts
Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.
The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.
Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.
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.
It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.
