Potholes

How potholes form

A pothole appears when the road surface has been worn away and a hollow appears. Potholes can form quickly and can be a hazard to people using the highways.

Water seeps into small cracks in the surface and over time this can worsen. Water pressure and vehicle movements can cause a pothole to increase in size very quickly over the winter months as the water expands when it freezes, making the gaps bigger.

As traffic moves over the weakened area it causes more material to become loose and eventually a pothole is created.

Our repair criteria

We investigate all potholes reported to us and we also carry out routine safety inspections on our highways too. The busiest roads, redways and footways are inspected more frequently. 

Potholes can appear in between inspections so do report any you see on the roads and footways to us using the Report It section or call 01908 252353.

Any pothole over 4cm deep will be investigated. If there are several in one section of road, even under 4cm, we may plan to do a 'plane and patch' repair instead which is more efficient covering a larger area than individual pothole repairs.

POTHOLE INVESTIGATORY LEVELS

More than 4cm deep

A risk assessment is made. We will then prioritise a repair if required based on this e.g. within 28 or 84 days or it may require an emergency repair.

Less than 4cm deep

A  risk assessment is made to determine is the defect is a hazard and if a repair needs to be scheduled in.

We have to use this criteria to prioritise repairs as we have a very limited budget.
