"They leveled our patio and we were extremely impressed with the professionalism of the crew. Unfortunately, the patio sank a couple of inches within a month and they returned again, at no cost, and re-leveled. We are hoping that it will stay but, whatever happens, it is not the fault of their expertise but rather the ground continuing to shift. That is our personal assessment."

"Ray and Jacob came right out, quickly diagnosed my problem, and did exactly what they needed to fix it permanently. Super competent and really nice guys (Go Seahawks!). Ray also did a full inspection of my crawl space and attic for free as he knew I was planning to put the house on the market. Ray is certified for both mold and pest control and does not mind getting dirty to do a thorough inspection. I would give ten stars if I could!"

House Leveling questions, answered by experts

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.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

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.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

Concrete leveling is not typically covered by insurance. In some cases where the shifting concrete is caused by a natural disaster or storm, you may be able to file an insurance claim if your policy specifically covers those circumstances. In most cases, though, you’ll pay out-of-pocket for concrete leveling.
