"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."

"RealSeal installed new drainage tiles and a sump pump in my approx. 950 sq. ft. basement. They also installed a tough waterproof membrane around that periphery. In order to do this, they had to cut out the bottom 2-4 ft of the drywall and studs in 2 rooms down there, and dispose of the debris. The ONLY reason I'm not giving them 100% on quality is that, while replacing the cement and rebuilding the slab for my laundry tub, they did not make the slab level, which has resulted in adjustments that are difficult to make, as my laundry tub is extremely heavy and difficult to nudge. Other than the problem with the slab, the workers were professional in their manner, and it appears that RealSeal has equipped them with very good gear and conditions; they seemed to actually enjoy their work. Jose, the foreman, was extremely helpful in answering all of my questions. And Dan, the salesman, was also great in answering my many, many questions. The video on RealSeal's website was a good resource for me in envisioning the project. I would definitely recommend RealSeal to others."

"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

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.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

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.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

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.
