"Amazing! My sidewalks were a trip hazard. I could not enjoy my front porch because I thought someone would trip every time they walked by. First Quality came by and in ONE HOUR my sidewalks were level. I only wish I did this sooner! I can now enjoy my front porch again! No mess, really professional work men, great work! Thank you! Thank you!"

"am writing to express my sincere appreciation for the outstanding service provided by Corey throughout my recent basement sealing project. From the very first interaction, Corey demonstrated professionalism, courtesy, and an impressive depth of knowledge. His ability to clearly explain the scope of work and answer all of my questions put me at ease regarding this significant and costly undertaking. What truly set Corey apart was his patience and dedication, even after the project was completed. He remained available to address my concerns and ensure that I was fully satisfied with the outcome. His thorough approach and commitment to customer satisfaction were instrumental in my decision to move forward with your company, even at a higher cost. It’s rare to encounter such a level of integrity and care, and Corey’s efforts have made a lasting impression on me. It’s thanks to professionals like Corey that I have full confidence in the quality and value of your services, and I would gladly recommend ground works to others based on this experience."

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.

"We had several wide and narrow cracks in a 15 year old driveway, which they filled and sealed neatly. The seal coat material was put down in a clean and professional manner. There was no splash or spill on the surrounding concrete garage aprons or stone block, or on the grass. They left no footprints in the seal coat and took away all debris. Just a really clean job. We had an issue with an unexpected storm washing away some uncured material in a small heavily shaded area a couple of days later. They came back and recoated the area. The job came out great. The company is responsive to phone and text messages, and they arrive on time. Overall a good experience."

Concrete Leveling questions, answered by experts

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.

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.

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

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

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.
