"This was our second time working with Permeseal. Had a great experience the first time was they remediated four foundation cracks. This time, stabilized concrete steps that had pulled away from house, amd leveled out a sidewalk.. They explained the remediation effort and went to work. Very conscientious and true craftsmen."

"Herb Blackmon was our first point
of contact with US Waterproofing.  He provided a detailed explanation of
what was causing the leak in our basement.  Herb was very knowledgeable
and explained the issues we were facing in a manner that was easy to understand.
 He presented us with several options and we decided to install the drain
tile system in our entire basement as well as a new concrete floor.
The job took about a week to complete.  It was originally supposed to take about 48
hours but when we decided to have a new floor installed and to have the old
floor dug out to gain a few inches of height in the basement it extended the
time of the job.  The crew arrived
promptly every day and began by breaking up and removing the old floor.  Once that was done they began the process of installing
the drain tile system and digging out the dirt/sand to gain additional ceiling
height.  Once that was complete they
dumped the rocks and gravel and began laying the concrete floor.  We were very satisfied with the work of US
Waterproofing from start to finish.  Herb
was an awesome salesman.  He was
knowledgeable without being undermining and pushy and he was patient and gave
us great advice about how we were to proceed. 
The crew was hardworking and professional.  I would recommend US Waterproofing to anyone
seeking to address leaky basement issues or have a new floor installed. The
quality of their work enabled us to be able to remodel our basement."

"What a positive experience. I thought Manny was great, and Luis was as well. It’s such a stressful thing to have water coming in, but I felt so much better after Manny’s visit, and after Luis’ work. It was such a great experience, I will recommend Real Seal to anybody I know that has water issues. Luis had to take down drywall to get to the problem, but you'd never know anyone was in the house doing any work. He cleaned up and left it spotless. I found Real Seal to be up front and honest, in fact my bill was less than quoted. And it's a lifetime warranty! You can't ask for better than that. Highly recommend."

"This job went great from the start. From the moment the estimator came to our house for the first time, I felt comfortable that this was the company to use for our job. I had received 3 other quotes, but I could tell there was a level of professionalism and knowledge the others didn’t have. The price was competitive and the plan of work addressed everything we needed. The work crew was professional, timely and responsive, courteous and respectful of our home, clean, and highly customer focused. I would not hesitate to recommend Atlas to anyone. Thanks for a job well-done!"

"I needed the sill plate and rim joist replaced, sister in the joist in the front of our house. They had many jobs going on so they brought in a crew Anthony, Jerry and Jose from New Jersey so the could get mine done. Anthony let me know what they were doing as things progressed. He asked me if I had questions as he worked. Everyone in the crew where so considerate. The laid down tarps to walk on so as not to damage my floors and they cleaned up everything and the end of the day. I would recommend Chicago Basement Solutions to anyone who needs work done in their crawl of basement."

"I had been having water leakage problems into my lower level family room for quite some time. Real Seal correctly diagnosed the problem, quoted a reasonable price, showed up to perform the work per agreed upon date and fixed it permanently. Even with the wet spring this year, I have not had any further water leakage problem. I highly recommend this company"

House Leveling questions, answered by experts

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.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

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.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.
