In Kingsport, TN, a residential property's front sidewalk had sunk due to changes in temperature and shifting soils that affected the moisture levels in the soil. Additionally, settling signs were evident on the driveway's side. To address this issue, Master Services employed the PolyLyft injection technique to raise the entire driveway. This method involves the use of PolyLyft, which expands and lifts the concrete, restoring the slab to its original position.
