Warning Signs of a Sinking Driveway
A sinking driveway may begin with a small height difference between slabs, but settlement can continue as the soil beneath the concrete loses support. Watch for these common signs, especially near the garage, sidewalk or street. A professional inspection can pinpoint why the concrete is moving and whether concrete lifting and driveway leveling will restore the surface and prevent further damage.
Causes
Why Driveways Sink
A driveway slab depends on stable, well-compacted soil beneath it. If that support settles, washes away or shifts, voids can open beneath the concrete and let sections of the driveway sink. While several factors may contribute to settlement, the concrete itself is rarely the problem; it’s the supporting soil. Determining why the support was lost is an important first step in recommending the right concrete driveway repair.
Why a Sinking Driveway Shouldn't Wait

Stage 1
Minor Height Differences
It often begins with a slight dip or uneven transition between slabs. At this stage, homeowners usually spot water pooling, rough vehicle transitions or a minor trip hazard.

Stage 2
Progressive Settlement
As the supporting soil continues to settle or wash away, the height difference increases. Cracks can widen, water intrusion may worsen, and the driveway becomes harder to shovel, drive across or safely walk on.

Stage 3
More Serious Damage
Without repair, settlement can continue until sections of concrete crack, break apart or become too damaged to lift effectively. At that point, replacement may be necessary, resulting in a more expensive and disruptive repair.
