In Blountville, TN, a cabin with a sagging back porch raised concerns not only about its appearance but also about potential safety hazards and structural damage to the cement slab. To address this issue, our team employed PolyLyft, strategically injecting it beneath the slab into the empty pockets of dirt created by water erosion. As the PolyLyft filled these voids, it expanded and lifted the slab, providing stability for years to come.
