What causes potholes?

A  pothole can occur at any time and are usually caused by the road surface being damaged and allowing water to penetrate. The damage gets worse during the winter months where the water freezes and expands, causing the road’s surface to be broken up and dispersed.

Potholes are an inevitable part of urban life because our busy west London roads are heavily used.

This, combined with the seasonal cycle of wear and tear, freeze and thaw means that the surface of our roads gets damaged, giving rise to defects, including potholes. Potholes are hazardous as they can damage cars and give rise to accidents for cyclists and pedestrians.
