"From the initial phone call to the completion of the job Quality 1st provided top notch professional service. A couple points which makes this easy to write. Communication is key whether in person or via telephone and Q1 was exceptional in this regard at every point. Telephone conversations with customer services was pleasant and cordial, never rushed or snotty. Paul our salesman was here for quite a while answering questions and assessing our needs in the basement. Of only was he on time for our appointment he was about 10 minutes early too. The cost of this project was a good chunk of change for us but after too many times of shop-vac’ing water we knew it was time to bite the bullet and move forward with making life a little easier and not have the issue of when will we get water in the basement again hanging over our heads. I was impressed that Quality 1st uses their own products and has their own R&D facilities. As for the installation, enough cannot be said for the crew that was here. I got the call at 9am they would be here in 20 minutes and at 9:20 they were backing in my driveway. I met the foreman Mario and his 2 helpers. We went into the basement and they looked around and asked if I had any questions. We had almost everything out of the basement and what was left they covered in plastic. By 9:50am they were running the jackhammers. We have a 1,500 sqft ranch and these guys worked all day, they didn’t stop and worked their tails off. I can’t remember exactly when the jackhammer stopped but by 2 pm the channel was dug out and they were beginning to lay out for the channel that carries the water to the sump. About 4pm Kyle showed up to assess the job and see if I had any questions or concerns. We spoke about the job and we went downstairs to see the progress. He stayed on site for about 45 minutes after making sure I was comfortable with how the job was going. By 5:15 or so the job was completely finished. Before they left Mario went over everything regarding the sump system. As far as cleanup, this is a dusty job. Concrete dust is ultra fine and they did a fantastic job of not only sweeping but they also dusted off areas which were not covered in plastic. They left no mess to speak of., I was very satisfied with their work and attention to detail. It’s easy to nitpick any job at anytime and there is nothing I would call them out on. Finally as for the functionality of the sump system I wish I had a comment on that at this time. We’ve lived in our house for 25 years and until around Thanksgiving of this year (2018) we’ve only had water about 4 times. Between Thanksgiving (2018) and New Years (2019) we got slammed 4 times and nothing since. With the symptoms of how our basement got water, I feel comfortable with the system Quality 1st installed and am confident they will stand behind their work and warranty. We’re also happy this is transferable to the next homeowner when we sell the house and it is an excellent selling point when the time comes."

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.

"Wow! Anthony and his crew were great! Had to wait a few weeks to get the project started, but showed up as promised and delivered excellence! His crew worked sun up to sun down to get everything done on time. Bond posted and permit with town all went smoothly. The coordination of cement truck and even helping lower water & sewage pipe in driveway was no issue. Anthony demonstrates absolute professionalism and is a real pleasure to work with. I would recommend him over and over again to anyone in need of a new driveway/walkway/ or garage floor!"

"Larry came out and did an analysis of our exterior drainage system, as we were having some puddling issues in the front and rear of our yard. We had just moved into the home a few months prior and Larry also did an analysis of our basement as we were having some concerns about the slightly bowed wall in our basement. Larry was very thorough and took a lot of time to go through the details of the exterior french drainage system he would install. He responded back to us in a timely manner and was extremely reasonable with their quote compared to other bids we had received from other contractors.
Larry and his team came out to the house and made quick work of a tedious job.  They took good care to keep the job-site as tidy as possible. Although Larry changed from the original plan, we felt comfortable with this as he was very thorough when explaining the reasons behind the change and we felt he had our best interest at heart. If we had any questions Larry was always available to answer them for us even when we called at 9pm.
We had a walkway that they had to cut through in order to run the piping for the drainage and Larry even added concrete to fix the walkway even though it wasn't in our original proposal.
We feel like with the work that was completed we got an excellent price and we have the peace of mind knowing that the job was done properly.

"Chris and his crew were excellent. The extent of Chris' knowledge was quite impressive. He made me feel like I was finally in good hands by showing and thoroughly discussing everything he found. During his inspection he checked every possible issue that could be causing the problems. He explained the repair processes necessary and showed me as he was doing them. They were courteous and cleaned up, leaving my property cleaner than when they arrived. They were very polite and more than willing to do whatever was necessary to help me complete the project as I wanted. I can not thank Chris and his team enough and would absolutely recommend their services."

Concrete Leveling questions, answered by experts

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

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.

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.
