Before Concrete Lifting:

Driveway Cracks
The homeowners noticed that sections of the cracking driveway were also uneven, particularly in front of the garage and the primary entrance to their home. Concerned about potential safety issues on their property, they wanted to find a lasting solution to enhance their well-being.

Sinking and Uneven Concrete Slabs
During an on-site evaluation by an expert from AFS, the inspector measured for sinking and noted that some areas of concrete had settled nearly ½ inch.
After Concrete Leveling:

A Safer Home
Our inspector recommended the perfect solution for the homeowners: concrete driveway repair with polyurethane foam injections. Polyurethane injections are lightweight yet long-lasting and quick-curing.
Focusing on the front and garage entrance driveway slabs, a crew installed the solution in one day. This minimizes downtime and allows the homeowners to use their driveway the same day as the installation. The owners also no longer have to worry about tripping on the concrete, as this solution enhances the safety and appearance of their home.
