Homeowner Shereena has lived in her 1920's home since May. She first noticed the problems with her sidewalks and driveways as soon as she purchased the home. She wanted to have them fixed as soon as possible as it was an eyesore and a trip hazard to the home. Having concrete lifting and leveling comes in the form of a polyurethane foam that is injected under the concrete slabs. The foam fills the void under the slab and expands. After expanding the foam hardens to keep the concrete slab lifted. After the concrete has been lifted the cracks are filled to give the sidewalk and driveway a cleaner look.
