Erosion is a common cause of sunken concrete. Erosion washes away soil from under your driveway, creating a void or space under the concrete slab. Your driveway can begin to sink in areas where the soil has been washed out. Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse. A heavy load, such as an RV that’s kept in your driveway, can cause sections of the driveway to sink and crack over time. If you have a newer home with a sinking driveway, it could be because the ground around the house is settling or the base of the driveway was not compacted properly. A sinking driveway near your garage can lead to foundation cracks and expensive damage over time.

PolyLevel® is a fast, effective option for repairing your sunken concrete driveway. First, your contractor will drill small holes in the slab. Then they will inject a high-density polyurethane through the holes. The polymer will spread beneath the slab and lift it up. Finally the holes are patched and the cracks are filled. You’ll be able to use your driveway within one day.
