"I called US Waterproofing. They were able to schedule me quickly and sent tech John Shea, who arrived promptly. He was very methodical and logical about going down a list of possible causes. The 3rd thing he tried was testing whether a long drain outside the building was clogged. Another contractor (see Trojan Plumbing review) had said the drain was fine by just looking and not testing. After John told me the drain was clogged I took off all the covers. It was completely clogged. I ended up taking 5 gallons of sludge out of the trough and another 2 out of the drain where i could reach. The next day I had a plumber rod the drain 25 ft. and he took another 3 gallons of sludge out. The drain runs fine now and a couple of light rains have caused no problem. John was with me over an hour and did not charge a dime."

"Very well, our home is more leak proof / water tight than when we bought it some 30 years ago... and is anticipated to remain so for another 30+ years. All the mentioned work occurred during 3 visits spread across some 18 months; but none of the visits required more than a single day to complete. Work was conveniently scheduled and the worker(s) always arrived on time; if not 15 minutes early. A year after our last work was done (the poly-jacking), The Real Seal, at my request but at no charge, even sent out a technician to replace/redo some concrete plugs in those poly-jack holes that had popped out probably due to outdoor temperature swings."

"These guys are amazing! They took a concrete pad, cut it in half and raised one section to create a step. This allowed for easy entry into our building instead of a high stair. Secondly, they leveled a 50 foot long span of sidewalk where each section tipped a different direction. It was a mess and they made it smooth and hazard free."

"Jason and team did a great job.  Jason came out within a day or two from my initial email and we discussed all the options/services they provided (liner, concrete, crack repair, and spray foam insulation.  I really appreciated how he discussed the pros and cons of each solution and his low pressure style.
ABC Crawlspaces prices were the the lowest of all the bids I got and I was even told by other insulation companies if I could get closed cell insulation for that cost that I should go for it.  The best thing was their service and quality of work.  It is rare to find a company that has fair prices and good service, but ABC Crawlspaces is one of those companies.  We are very happy with all they did for us and our basement is much more usable and the air quality has improved dramatically.  Thank you Jason!"

"Brian and his crew returned to my building on a warranty followup- their previous work done wonders for my flooding problems, but my foundation walls are apparently made of swiss cheese and there was one small seepage problem remaining which only shows up during a "100 year rain event".  Brian indicated that they go for 100%, not 99% and scheduled time to come back out to my building to address the issue under the warranty (a.k.a. free of charge) from the original work.  They came back out, dug up the foundation again, and found a crack hidden behind an old hasty concrete patching job that had been tarred over, which was determined to be causing the remaining seepage.  They repaired the crack and were done with the whole task in only hours.  I am a repeat customer, and can't say enough good things about Crawlspace and Basement Waterproofing solutions, they are friendly, helpful, and most of all, stand behind their work!

"Luis of Designer's Concrete set up an appointment to make an estimate, and arrived at the appointed time. I had already had the utilities located. We talked it over, and he explained to me what was necessary, and the reasons for the cost estimate of $1000. He said he would take care of getting the city permit for the project, and he stayed in contact with me throughout this part of the process. He knew exactly what the city needed from me. Once the permit was given, Luis arrived with his crew, and laid in the form. The city had to inspect the form and foundation for the pad, but once they had, the crew returned the next day and finished the job. The longest part was waiting for the city permit (about a week). When that went through, it was only three days until it was finished. Luis told me how to cure the cement before I drilled into it to install the shed. Luis accepted the Angie's List coupon. He followed up with a call a few days after it was complete. They did not mix the cement on my property, but had it delivered. Personally, it seemed more expensive than I thought it would be, but that was probably just my ignorance going into such things. Overall, it was a great experience working with Luis and Designers Concrete."

Concrete Mudjacking FAQs, answered by experts

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.

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.

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.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.
