Stopping your driveway from becoming uneven requires professional tools. FSS uses polyurethane injection, a modern approach to concrete lifting that uses the same idea as mudjacking but gets rid of the mess and the long completion times. Polyurethane is a foam material that essentially starts as a liquid. Using specialized equipment, our team injects the solution below uneven concrete, where it quickly expands and hardens enough to support the weight of your driveway in just 30 minutes. Polyurethane also protects against soil washout, dry conditions, and expansive soils by acting as a barrier between the soil and your driveway.
