"Mark arrived and viewed our problem. He gave us sound advice about how to fix our water intrusion problem. Unfortunately, his company does not provide the service we need (pouring concrete). His advice was sound and made so much sense to us. We had met with another company who recommended a variety of measures which were all extremely costly. Mark was honest and credible. The Moisture Loc company must have great ethics to offer advice that will take their business to a different company. We will definitely keep this company in our rolodex!

"Review by Iris F. in Camden, SC Project: Repair a Concrete Foundation I had a unique problem with termite damage to an old Pier and Beam home. Damage was causing floor sagging and instability in the foundation of the home. (It failed several inspections). I was trying to sell the home and had to have the problem fixed. I had several estimates from general contractors in the Camden area. ALL of them wanted to fix the problem by going through the interior floors to get to the support beams. I did an online request to have an estimate from Canty Foundation. From the initial contact with William Yarbrough/Sales to the Onsite foreman Jonathan Driggers I was impressed. This is a 100 year old home and going thru the inside floors would have created damage that would have been difficult to fix. CANTY did all the work from the crawl space. They were professional and work was completed on time. The home passed all 3 inspections and I completed the sale. When you have a foundation problem I learned to call the experts. AMAZING job guys!!!!!"

This is just one of the foundation cracks we found on this foundation. It's what we call a stair-step crack.

Concrete Mudjacking FAQs, 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.

Costs range from $500 to $1,500, depending on the size and condition of the area.

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.

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.

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.
