You should report a problem with any highways in the county directly to Cornwall Council.


Potholes can occur for a number of reasons, from wear and tear of passing traffic, to weather conditions and subsidence. We undertake regular safety inspections across our highway network, but potholes can develop overnight, and without warning. You can help us identify the location of potholes by reporting them using the ‘report a problem’ button above.

For urgent problems or emergencies outside of normal office hours please telephone: 0300 1234 222.


When potholes will be filled

Safety is always our primary consideration.  Some of the factors we take into account when prioritising pothole treatment are:

  • the size and depth of the hole;
  • the volume of traffic (vehicles or pedestrians);
  • speed of an affected road; and,
  • the likelihood of the defect contributing to an accident.

If a pothole is considered to be a significant hazard, it will be treated by the end of the next working day.  Those that are not likely to be dangerous are added to our list of programmed work and normally treated within six months, often as part of a wider patching or surfacing programme.


How potholes are repaired

A typical repair involves cutting a rectangular area out of the road around the pothole. This hole is cleaned out and painted with liquid bituminous binder. Then it is filled with a hot bitumen-bound material. This is raked and mechanically compacted. 

A temporary repair is a quick, short-term measure to make the road safe. Normally we clean loose material from the pothole, fill it with a material that can be laid cold, and then compact it. Temporary repairs are short term solutions that ensure traffic safety until a permanent repair can take place. 

The choice of repair reflects how safe it is for our gangs to do the work and the amount of disruption our work will cause.  Temporary repairs are much quicker for us to do.

Temporary repairs are followed up at a later date with a permanent repair which may be part of a routine patching programme, or as part of our programme of surface treatment. These programmes are planned well in advance and allow us to schedule larger, more complex or time consuming repairs at a time that will minimise the disruption to road users.
