"This is a review of the *experience* we had with Quality. We had the basement waterproofed, so we won't really know how good the job is until a big rainstorm! So this is just the experience we had before and during the job. We reached out to Quality based on the Angie's List reviews, and were convinced by the visit from Greg. He was so knowledgeable about the water problems, and pointed out the years of experience the company has. Also, we weren't looking for a bargain, we were looking for a dry basement, and Greg was very straightforward about all the costs. Now we haven't had a rainstorm yet, so we still don't know the most important thing about the job! But Victor and his crew were fantastic. They knew what they were supposed to do when they got here, and did the whole job-- as quietly as possible-- in less than 4 hours. They were pleasant to have in the house. They left the place clean. So big thanks to all at Quality. P S: Will update when there's a big rainstorm."

"HIGHLY RECOMMENDED!!! We just had a French drain installed along with a new sump pump and pit in our basement and had the floors epoxyed afterwards. The project manager, Kenny, was absolutely amazing. From the very beginning he explained everything that their team would be doing, gave me updates throughout the day. If I had a question or concern Kenny was patient with me and continued to make sure any questions/concerns were addressed, even telling me to call him if I thought of any other questions. Their crew was very respectful of the property by making sure to lay out tarps to protect the floors, and made all attempts to manage the noise since we were home. Whatever was left in the basement they made sure to cover and protect. And if something needed to be moved they moved it and moved it back. When it came time to lay down the epoxy there was a scheduling hiccup. Kenny though went out of his way to make it right by coming right after another job and staying late to make sure we're stayed on schedule since I was having out of town guests coming that weekend and needed access to the basement. Working with Select Basement, but especially Kenny, made this one of the best experiences and I highly recommend them. 10 out of 10!"

Introducing Concraised, Leveling your concrete so it’s as even and great looking as the day it was poured.\n\nAt Concraised we use the Foamjacking method to level & repair sunken concrete surfaces. We serve homeowners, residential and commercial property managements & municipalities.\n\nHow it works:\nConcrete slab lifting works like this:\n\n1) Injection of environmentally-safe foam under the existing concrete\n 2) Foam expands to fill the void at the same time compressing the soil underneath\n 3) Slab is raised completely back to level\n\nConcraised, making great first impressions, one perfect walkway at a time.

"The crew was good.  The quality of the work is good.  I would recommend them for any concrete work whether old or new or repairs from them.   They did a great job coming up with a good plan to repair my concrete deck around my pool.  Don't hesitate to use them.

"We had known about this problem for some time and had also had a structural engineer evaluate our situation.  We may be putting our house up for sale soon and decided it was finally time to get the wall fixed.  Armed with my own research and the engineers evaluation, we searched for a contractor to perform the work we knew we needed to have done.  Upon contacting Foundation Experts, Larry got back to me very quickly and we set up an appointment for him to inspect the wall.  He was VERY thorough in explaining what needed to be done to stabilize the wall to prevent any further movement/damage.  He said we should have the wall "pinned".  He quoted us $4000 to do the whole job (10 pins along a roughly 25ft. long wall).  They also designed the system so that the re-bar would pass through the top course of block and attach to the house sill plate above the wall to help lock it in place.  
The price was on par with most other estimates (slightly cheaper actually), but we decided to go with Foundation Experts mostly because they were very thorough with their evaluation, were honest (I was armed with a lot of info about our situation and felt very confident that what he proposed to do was exactly what needed to be done) and they did not pressure us at all.  I also really liked the fact that they routinely work with engineers and felt that they had a better grasp on executing the work over other contractors we contacted.  They also will work with the township if permits are needed.
We scheduled for the work to start the following week.  Their team took about 2 days to do the work.  They were very professional and did not make a mess at all.  They put plastic up to prevent concrete dust from getting everywhere in the basement and cleaned up thoroughly.  Larry was present during the bulk of the work and made sure that everything went smoothly.  They even worked with us on the payment method.  He made it very clear if we have any issues/concerns or questions to call them anytime.  He also stressed that if we sell the house and potential buyers have any questions/concerns to contact him and they will work with us as best they can.  
The wall is now fixed and my wife and I feel better knowing that our wall won't come crashing down during then next heavy rain!  We also feel better knowing that we won't have to worry about foundation issues coming up if/when we sell our house.  All in all, it was a great experience!

"Tommy and his crew were great. I had a 1000 square foot patio installed by him. 22 yards of concrete, and stamped. My wife and I couldnâ t ask for a better experience with a contractor. Great estimate, with no changes, thorough, clean, on time, had talented workers, and very detailed. Even went as far as coming back on the next day(Sunday) to cut the relief cuts. Most guys would have left it til Monday. All in all, A+++++. Definitely use this business!!"

Concrete 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.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

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.

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.

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.
