Before Concrete Lifting:

Safety Concerns
The homeowner first noticed that their porch had become uneven, with one side clearly sinking. The slanted slab not only created an eyesore but also introduced safety risks and made daily use of the entryway difficult.

Underlying Soil Settlement
Upon inspection, the AFS team found that the soil beneath the concrete had shifted and settled—leaving voids that caused the slab to sink. Without correction, the damage could have spread to nearby areas or worsened the slab’s condition.
After Concrete Lifting:

Fast Foam Injection, Immediate Results
The crew drilled small holes into the sunken sections of the porch and injected lightweight, high-density polyurethane foam through the SettleStop PolyRenewal™ system. As the foam expanded, it filled the empty spaces beneath the slab and gently lifted the porch back into position.

Clean, Controlled Concrete Lifting
This method allowed for a precise and minimally invasive repair. The surface was restored without excavation or demolition, and the foam cured quickly—allowing the porch to be used the same day.
