Before & After

There was a large "stair step" crack along the brick fascade of this Knoxville, TN home. To fix it, the Master Services 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.
This home’s front walkway had shifted and settled over time, creating uneven sections that posed a tripping hazard and affected curb appeal. Our crew used a polyurethane foam injection system to lift and stabilize the concrete, restoring both safety and appearance.
This driveway was cracking. When there's too much rain, it can wash away the soil under concrete. Too little rain, and the clay-based soil will contract and shrink. Both of these extremes can lead to cracked, uneven pavement. To fix the problem, Master Services leveled the concrete slab by injecting it with PolyLyft.
