"I could not be more pleased with Joseph and the work he performed. I needed an existing patio to be replaced due to tree roots which impacted drainage towards the house foundation. After 5 bids, I decided to go with Joseph due to his competitive bid and demonstrated expertise. He and his team were stellar, solid communication, friendly, and took the time to explain to me the leveling/answering all my questions. In 3 short days the project was completed and it looks great. I would highly recommend Joseph to anyone looking for concrete work."

"Nelson and his crew did a fantastic job! We did a large concrete slab in our backyard garden, 800sf. We wanted a modern look and various shapes to fit our landscaping. Nelson did exactly what we wanted with a very positive attitude. The work was done very professionally and fast as they have all the necessary equipment. They first excavated, then put gravel and compacted it, installed rebar enforcement every 16 inches crossed, and poured the concrete. Everything was leveled, with the proper slope to take water away from home. They finally did a light broom finish. We are glad we found them on Angie's list and highly recommend them."

"Their work was very professional and courteous. The perimeter drain involved a lot of jackhammering, and hauling buckets of concrete/rubble out, as well as mixing bags of concrete and hauling many bags of concrete. All *very* labor intensive. While on the worksite, they accidentally struck three sewer lines, and performed repairs. Some of these repairs required extra work, which we negotiated to my satisfaction with their supervisor before the job was complete. The drain itself has been in place for one full year now, and has certainly prevented my basement from flooding at least 5 times this winter. I can hear the drain pipe discharging into the sump well when we are at flood stage. The pump, drain, and discharge work all as expected, except for one caveat. The bid was for a complete perimeter drain along the basement cold seam, except where the basement fireplace is located. It terminates at both sides. When receiving the bid, I asked if that was going to be a problem, he said no - there was sufficient drainage to intercept any water on either side of the fireplace. Later that season, I contacted Permadry because we noticed visible wet spots on either side of the fireplace in the few inches between the fireplace and the end of the drains. This, and the continued efflorescence in the brick meant that we had a moisture issue on the fireplace. Upon contacting them, they told me that they do not do fireplace work. I reminded them that they stood by a lifetime guarantee for their work. They reminded me that it doesn't include fireplaces. So, I have minor water intrusion next to my fireplace that they were unwilling to inspect or troubleshoot. But my basement isn't flooding. Later that Spring, when conducting a sewer repipe under the house, we uncovered debris (cast iron and rubble) that had gone into one of punctured sewer pipes, and had traveled 8 feet. The unforseen work is always unforseen. However, my pipe repairs could have been problematic. During our repipe, we re-laid all the pipe Permadry repaired. And, while their repairs were serviceable, they were not done as a plumber would have and could have caused problems in the long term. The debris certainly would have. While this review may sound overly-critical, I am not critical of this company. I had a very large, unpleasant job and they carried it out with great professionalism. I would hire them again. Unless I can find a company that includes fireplaces in their waterproofing work."

"We've had a handful of unsatisfying contractor experiences, so we tend to be a bit skeptical but our experience with Terra Firma set a new bar for us. Highly professional from start to finish. Initial consult was thorough, and didn't add on anything we didn't ask for or need. When they were working at the house the crew was prompt, professional, left the jobsite clean each day. Final result was exactly what we were expecting. Worth the investment, don't go with the lowest bidder on your foundation, it's not worth it. Thank you Terra Firma crew!"

Concrete Leveling FAQs, answered by experts

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

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.

Most projects take 1-3 hours, with immediate usability after completion.
