"Joseph is a great guy, hard worker and takes pride in his work. We pulled out all of the grass in our backyard and laid concrete down to extend our existing patio. Joseph showed up on time everyday, did what we agreed to do. No complaints and i would recommend him."

"They almost finished but I made the mistake of paying when they were almost done. They didn't show up to remove the last of the plywood forms for the retaining wall. I called at least 4 times and requested that Nelson, the owner of the Co. to send someone to complete the job. He told me 4 times ok and gave me a day when they would come to do that. All 4 times no one showed up. And no one called to say they wouldn't be there. I feel that Nelson was playing with me but do not understand why? I paid in full. $12,000 + tax. Also, he requested I make the check out to his name. I don't know if that is legal to do or not. But I did it."

"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."

"I needed a garden path from my house to my art studio, and I wanted it to match the concrete path already going from my house to the garage. Not a big job, but American Concrete Construction was willing to take it on. Their main guy, Sinisia Moli, came right out one day to evaluate the job, then returned the next day to survey, dig out the path, frame it, and put in rebar. Cement was poured the following day. And now I have my garden path. Which, incidentally, matches the other, much older path perfectly. ... Sinisia Moli of American Concrete Construction is a man of experience, good aesthetics, and common sense. He is also friendly, upbeat, and generally a pleasure to have around. Best of all, unlike so many of his colleagues who work in various construction trades, Moli talks to women. He doesn’t insist on talking to your husband. ... I am definitely keeping American Concrete Construction in mind for future projects."

Concrete Mudjacking FAQs, answered by experts

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.

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.

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

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.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.
