Potholes can develop quickly where the road pavement is softened, particularly when water has soaked into the road.
Potholes recur often due to their depth, as graders can only cut as deep as the gravel extends. Graders use their blades to cut into the road surface and reshape the road, which can help repair the recurrence of shallow potholes.
If roads are cut too deep, clay and other soil are brought to the surface, further degrading the road surface and damaging the surface layer.
Recurring deeper potholes can sometimes be resolved through re-sheeting, and we may apply this treatment when the road has many deep potholes. However, this may not always fix pothole reoccurrence if the issue is a weak sub-layer.
Applications for road sealing may be applied for under Council’s Special Charge Scheme.
