General Concrete Leveling and Repair Questions

What is concrete leveling and how does it work?

Concrete leveling is the process of lifting and stabilizing sunken or uneven concrete slabs without the need for total replacement. The most common method we use is polyurethane foam injection, a modern, efficient solution that fills voids beneath the slab and lifts it back into position. This technique works on sidewalks, driveways, patios, pool decks, garage floors, and more.

What causes concrete to sink or crack?

Concrete can sink or crack for several reasons:

  • Soil erosion beneath the slab
  • Poor compaction during original installation
  • Freeze-thaw cycles
  • Water intrusion and inadequate drainage
  • Heavy loads or traffic

Our team assesses the root cause during a free evaluation so that we can recommend the best long-term solution.

How long does concrete leveling take?

In most cases, concrete leveling can be completed in just one day. The actual process usually takes a few hours, depending on the size and severity of the issue. After the procedure, the area is ready for use again within minutes to a few hours, making it a fast, convenient alternative to replacement.

Is concrete leveling a permanent fix?

While no concrete solution lasts forever, polyurethane foam injection offers long-lasting results. Our materials are resistant to moisture and erosion, ensuring a durable lift. Plus, our life of structure warranty provides peace of mind that you’re covered in the long term.

How much does concrete leveling and repair cost?

The cost varies based on the size of the area, the extent of the damage, and access to the affected section. Concrete leveling is often more affordable than full slab replacement. For an accurate quote, we offer free, no-obligation assessments.

Will my concrete be damaged during the repair?

No. The process is minimally invasive. We drill small holes (about the size of a coin) in the slab to inject the foam, then patch them cleanly once leveling is complete. The aesthetic impact is minimal and far preferable to tearing out and replacing the slab.

Can cracked concrete be repaired too?

Yes. If your slab has cracks in addition to sinking or settling, we can repair those as well. Our team evaluates the extent of the damage and applies solutions like crack filling or sealing in addition to leveling to restore structural integrity.

Is concrete leveling safe for all types of properties?

Absolutely. Whether you’re a homeowner dealing with uneven sidewalks or a business owner needing a safer loading dock, our concrete leveling solutions are safe and effective across residential and commercial properties.

Dale and the guys did a fantastic job. We had a significant wall lean, and they made the repair look easy. They walked us through the permit and inspection processes. Their work is quality, and they are easy to work with. Highly recommended.

My experience with Cornerstone was a few years ago. I had a sump pump completely replaced, an entire basement wall braced and an outside (garage) wall piered. I have not had a problem since the work was done. The workers and the owner, Dale, were at my home when they said they would be. I am pleased with the work that was done and found Dale to be a man of his word. I would not hesitate to recommend Cornerstone.

We were getting ready to close on our house and 1 week before closing a heavy rain came and we had water in our laundry room in the basement. Dale and his crew came out the next day and got started on fixing the issue. They were fantastic and very detailed in explaining what they were going to do. Had it done in their time frame and cleaned everything up. Very professional and excellent service.

Quality work from quality folks. I called on a Friday afternoon to get a quote for poly jacking our sidewalk. They came out on a Saturday morning to take a look and got us on their schedule. Quite happy with how the fix looks as well!

After the huge flood, we had July 26, 2022. I finally decided I’d had enough with the flooding issue and contracted Cornerstone Structural Repair & Waterproofing to knock out my sliding glass door in my basement and cement the opening to form a solid concrete barrier. I am very satisfied with the end results!! Dale and his workers did a great job, very respectful of the property, very friendly and professional, and cleaned up after the work was completed. It has already come in handy after 27 years of dealing with flooding in my basement and replacing numerous appliances. I can be at peace now not having to worry every time we have a torrential downpour. Please see attached photos of the 2022 flood and the flood event this year in April. Kudos to Dale and his team!!!! 😁
