Key takeaways
- Potholes start with water getting under the asphalt.
- Freeze-thaw and traffic break the weakened surface.
- Cut-out repairs outlast quick fills.
- Fixing drainage prevents repeat potholes.
How potholes form
Water enters through cracks and soaks the base. In winter it freezes, expands and lifts the pavement; when it thaws, voids remain. Tires then pound the weak spot until pieces break away and a hole forms.
Repairs that last
A durable repair cuts out the failed area, removes wet or loose material, rebuilds the base, tacks the edges and places hot-mix asphalt compacted flush. Cold patch is a temporary fix when hot-mix is not available.
Preventing the next one
Seal cracks, keep surfaces draining and fix low spots. If potholes keep reappearing in the same area, look for a drainage or base problem under the surface.

Quick answers
Are potholes covered by insurance?
Policies vary. Document the damage with photos and talk to your insurer.
Why do potholes return after a patch?
Usually the base stayed wet or soft, or the edges were not sealed. A cut-out repair prevents that.
