"Eric the consultant inspected the job site took the measurements he needed and gave us an explanation of how the work was going to be handled. He also offered a discount and scheduled our project for the following week. When the day came the crew arrived on time and went right to work. We will use them again in the future for our pool deck. Overall a great bunch of people and a greater service."

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.

"Larry came out for an estimate quickly.  I had to postpone work a bit because of some other issues with the house.  When I was ready to go, Larry came back out and we went through everything again.  This time a few other issues were brought to light.  I went with Foundation Experts because the recommendations seemed more logical than other ideas that had been proposed by other companies.  Once the contract was signed, work began quickly.  Quite a few workers were there for different aspects of the job.  Everyone was very friendly and professional.  Andy was involved in different aspects of the project than the others and was very thorough in explaining what he was doing and why.  The job didn't really take too much time and was spread out over 2 days.  Everything looks good.  The initial reason for my call to them was because of water pouring into my basement when it rains.  Hoping that what they did will do the trick.  Time will tell.
I have a few future projects in mind for them in the future.

"Carlos and his team did an amazing job! They were thorough and answered all questions that we had. Carlos even came to my house during a snowstorm to explain to me in detail what he was going to be doing as I wasn’t there when he explained it to my husband. I couldn’t be happier with the great job that was done! I would definitely use them again and highly recommend them!"

"I was very happy with the finished product. He did the first part and the we hired them to finished the last part of the pavement. We really loved the work. It was pricey, we thought however we loved it and everyone constantly gives us complements on the pavement. They came and finish the job in great time . They were respectful of our privacy and try to finish the project quickly. Came early and left at a reasonable time. Completed the job when they said he would. Definitely will use them again."

"Wonderfully. The Al-Arsh crew is always reliable, prompt, professional and highly-skilled. Their work is always done exceptionally well and the owner, Malik, always makes sure it is finished to perfection. Even when we needed something tweaked or if plans changed after they finished, they come and do whatever is needed when needed, cheerfully. Their prices are more than fair and they guarantee their work. We have had Al-Arsh do work for us over the years totaling at least $250K and we ALWAYS chose them."

"Roca and his team were very professional and did a thorough job on repaving my driveway and repairing our front sidewalk. The team delivered as promised and on schedule. In addition they worked quite fast although it was clear they paid attention to the important details. I would surely hire them again and am quite satisfied with the work they did ."

"Felipe and his team did extraordinary work. Both interior and exterior painting and staining, cabinet mounting, garage exterior refinishing. They understand how to find the safest and most correct way to do carpentry and any beautification you may need. They are lovely to work with and take true pride in their work. I felt like there was nothing they couldn't do at a very high level. You will not be disappointed."

Concrete Leveling questions, answered by experts

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

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.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

Many contractors offer warranties for their work. Confirm terms before starting the project.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.
