Before & After

This driveway had a long, uneven crack running nearly to the road. We used a specialized polyurethane foam injection to lift and stabilize the concrete. As the foam expands beneath the surface, it fills voids and raises the slab back into place. The result? A safer, smoother, and better-looking driveway without the need for full replacement.
Master Services visited a home in Knoxville, TN to raise some stone steps that were sinking. Concrete often sinks due to soil erosion, rain, or drought. To fix these steps, the team injected the concrete slab with PolyLyft.
When this Knoxville, TN homeowner noticed uneven pavement in their garage, they called Master Foundation and Crawl Space Repair to fix it. Our team used high-density PolyLyft to raise the slab back to its original position.
There was a large "stair step" crack along the brick fascade of this Knoxville, TN home. To fix it, the Master Foundation and Crawl Space Repair team drilled holes into the concrete slab of the porch. Next, our high-density PolyLyft was injected into the holes. The polyurethane expanded to lift the concrete slab and seal the crack.
Sidewalks can create tripping hazards due to soil erosion or drought. To fix this threat, Master Services injects holes along the concrete at strategically placed intervals. Next, the team injects these holes with PolyLyft, which expands and lifts the slab.
