Polyurethane foam is better than traditional mud jacking to lift and level your concrete driveway, sidewalk, steps, slab, pool deck, garage floor or patio. An uneven driveway may post damage to your foundation. Polyurethane foam costs 50% less than concrete replacement. It is less invasive, uses less holes, is less messy (doesn't tear up your yard to repair), and less money than traditional mud jacking in less time! 40% of the jobs we do are because the mud jacking failed. Companies that use mud jacking are not bad, the process uses water and if the water evaporates, the concrete will sink again.
