SLAB LIFTING
Our unique and effective process for slab-lifting employs an array of special high density expanding polymers which are injected through small 5/8″ holes drilled directly through the concrete slab. As the resin mixture expands, voids are filled and a controlled mold pressure is exerted on a limited (8 to 10 foot diameter) area. The aggressive nature of our resins not only effectively fill voids under concrete slabs but also effectively under-seal the slabs and helps in preventing water infiltration. Once the voids are filled a controlled lift will ensue to align differentially settled slabs or lift settled concrete panels.
