safe and even driveway created by polyurethane foam injections

Safety is top of mind for a couple of longtime homeowners in Clinton, TN. As they grow older, they don’t want to worry about tripping hazards like cracked and sinking concrete on their property.

Motivated to fix this issue sooner rather than later, the owners contacted Groundworks’ Knoxville branch—AFS Foundation & Waterproofing Specialists—for an inspection and advice. An inspector recommended lifting and stabilizing the concrete with polyurethane injections.

The homeowners were eager to move forward with the efficient concrete leveling project to create a safer living environment.

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.

Talon was amazing, punctual, educational, patient, and knowledgeable! Took as much time as needed with us to make sure we were fully knowledgeable about all the issues that our new house had with water intrusion and structural issues. Was able to give us a quote the same day and even offered financing through a third party. Would recommend him to anyone buying a house or looking to fix water issues entirely. My father has experience in home building and home inspections and was very impressed with him and his information and processes. I will definitely have AFS do the work and trust them as a company now.
