How to Fix a Driveway That Has Heaved

Frost heaves can create deep, unsightly cracks in a driveway. Left unrepaired, these cracks spread and leave the pavement vulnerable to water damage. Fixing a heaved driveway is not complicated. Do-it-yourselfers can repair most damage with basic materials and a day of labor. If you notice deep cracks running through the entire slab, have a professional evaluate the driveway for major structural problems.

Instructions

    • 1

      Chip off loose pavement by placing the point of a cold chisel on the edge of a crack and tapping the other end with a hammer. Work down both sides of the crack, pointing the chisel to widen the base of the crack, and remove debris with a wire brush.

    • 2

      Flush the cracks with water to clean out any remaining dirt and debris.

    • 3

      Measure the depth of the cracks with a measuring stick. Fill any cracks deeper than one-half inch with sand until the crack is half full.

    • 4

      Fill in the remaining hole and any shallow cracks with reinforced vinyl patch compound. Spread it over the gap with a putty knife and tamp it down. Continue to add the compound until it is overfilled.

    • 5

      Use a flat trowel to spread the excess compound over surrounding pavement.

    • 6

      Blend the patches in with the rest of the pavement with tinted sealer. Paint it on with a rolling brush and plan to re-apply the sealer every few years.
