Concrete Floor Repair

Interior concrete, like concrete slabs outside your home, is prone to cracking and settlement. They can, however, be rectified! Learn more about those options here.

Schedule Free Inspection

Do you have a home with uneven or unlevel floors? Have you seen any doorway cracks or separations? If this is the case, interior slab lifting and concrete floor repair may be required to restore your floors. Allowing concrete slabs to sink and settle over time can cause major structural damage to your home.

How Interior Slab Lifting Can Help 

At Mount Valley Foundation Services, we utilize a special, polyurethane foam called PolyRenewal™ to lift and stabilize your home’s interior concrete slabs. It is a non-invasive process that can restore the original position of your concrete floor or slabs and give a long-term solution. 

When employing our polyurethane foam, our team of professionals is required. If our specialist suggests using PolyRenewal™ to elevate your sidewalk, here’s what you may expect: 

installing polyrenewal polyurethane injections
  1. To begin, penny-sized holes are bored into the concrete surface. 
  1. Injection ports are then added. 
  1. Using specially engineered equipment, the polyurethane foam is mixed and injected into the concrete. 
  1. It cures for 15 minutes, during which time it expands and fills gaps and cavities. 
  1. The injection ports are removed, and the holes are smoothed by drilling. 

Why Our Interior Concrete Lifting is a Better Solution

When it comes to our interior concrete floor repair, our polyurethane foam is ideal because: 

  • Quick Curing: Our polyurethane foam is capable of lifting concrete slabs and curing within 15 minutes. So, you can walk across your concrete floors the same day the foam is installed.  
  • Lightweight: Because polyurethane foam is so light, it’s ideal for regions like South Carolina, North Carolina, and Georgia where the soil is much more delicate than other soils. The foam will not put any strain on the soil where your concrete is placed. 
  • Water-resistant: Our PolyRenewal™ foam is resistant to moisture and water. It will also not leak dangerous substances outside of your home and into the surrounding environment.

Signs Your Home Needs Concrete Floor Repair 

Basement Floor Cracks

Basement Floor Cracks

Cracks in your basement floor can come in many different shapes and sizes. If your basement floor is crumbling, you might not know what to do to fix it, especially if you’re a first-time homeowner with limited home repair knowledge. If you see cracks in your basement floor, contact a professional.

Uneven Concrete Floor

Another indication that your concrete floor may require repair is if it begins to appear uneven. Some portions of the floor may appear to have sunk, and the surface is no longer as smooth as when it was first poured. If you notice unevenness, you should have it evaluated by a professional.

Sunken Floor

If you’ve seen water pooling on the concrete in your home, you should call a foundation specialist. You will notice that this happens often right after it rains hard. It also happens when water can’t drain away on its own. If the problem isn’t taken care of quickly, it can cause your concrete floors to wear out faster.


If the soil under the concrete slab is a weak, unstable type of soil, there is a much greater chance that the concrete slab will be uneven. If you put too much weight on a concrete slab, you might have problems with an uneven slab that has nothing to do with the concrete itself. 

Erosion beneath your home’s concrete slabs can be a problem, especially if your home doesn’t have a basement or crawl space and you have a lot of rain or floodwater in a short period of time. Erosion beneath the concrete slab can result in a variety of movement issues, including sinking. 

Every slab of concrete will ultimately settle. Because settling is caused by two factors outside our control — such as weather and soil — there isn’t much we can do but safeguard your concrete. There is no way to know exactly when you concrete will begin to settle. The best you can do is be aware of the problems signs and reach out to a concrete specialist as soon as possible.
