"Romualdo fixed our basement concrete floor to make it even and prepare it for vinyl flooring installation. His services were reasonably priced and he took the time to advise us on the different alternatives that we had to get the job done. He was kind and did an excellent job."

"NV Waterproofing polyjacked my driveway and sidewalk. The initial quote by Evan was thorough and professional - he spent a good amount of time answering all my questions as well. Once I was scheduled, Dillon was on time and knowledgeable about the work to be done. He did a fantastic job and was patient with me while I asked questions along the way. The weather turned to storms a little earlier than planned, so we had to schedule another day for him to come out and seal the driveway. On the rescheduled day, he came back out and sealed, but then there was a small issue with the joint compound refills. We scheduled another day for the project to be completed and third time is the charm. He finished the work and it looks great. There were a couple small issues with getting back on the schedule (communication with the front office, aligning dates, but it was resolved quickly - just needed to continue following up). Everyone I interacted with at NV was friendly and professional - genuinely"

"I had a great experience with Precision Renovation and Construction. They were much cheaper and easier to work with than the other contractors I spoke to about my job. I called them Sunday, someone came out to give me an estimate Monday, and they did the job on Tuesday. They charged me $200 to remove a large concrete block and repair some patio pavers. Other contractors quoted me several hundred more. James was very friendly and did a great job."

"Very pleased with our concrete leveling solution—we now have a safe sidewalk for our entryway again. It matched Bobby’s estimate, and their team was able to fit this small job into their workload without much wait. Before Bryan R. performed the task, he professionally explained what was going to be accomplished, how the process works, and provided several suggested recommendations. Would refer them again."

"I highly recommend NV Waterproofing & Foundation Repair! The work crew, Alfredo, David, and Javier were excellent! Alfredo Hernandez, the Foreman, kept me updated every step of the process, thoroughly answered every question I had, and addressed all concerns with expert problem solving and skill. These three men were in my home for a couple weeks doing extensive foundation and waterproofing work. They were always professional, courteous, and kept the work space clean. I was able to leave home for appointments with full confidence and trust in this crew. The sales manger, Brendan Feehan, was incredibly knowledgeable as well, and was able to solve every problem with my complex foundation and waterproofing issues. He was accessible to answer any questions I had throughout the process, and available to stop by as needed. Brendan is professional, helpful, and an expert in this profession. He's not just selling products. He understands the complexities of old and new construction"

Concrete Leveling questions, answered by experts

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.

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.

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.

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.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
