In the winter, more road defects and potholes form due to wet and freezing weather, causing those worn areas of the road to break up.

We identify potholes during routine road inspections by our highway officers which occur regularly throughout the year, and via customer reports from our highways reporting tool.

During winter we increase the number of work crews dealing with both temporary and permanent pothole fixes. Normally there are eight crews and two dragon patchers available across the county, now there are 30 crews and two dragon patchers working hard to repair potholes.

This enhanced approach helps us maximise the number of repairs we can deliver each week to meet demand.

Pothole fixing methods

The council uses a mix of repair techniques to keep the network moving smoothly. Here's an easy overview of the main methods in use today.

Reactive pothole repairs

These are day‑to‑day fixes carried out when a pothole is reported by the public or found during routine inspections.

Urgent potholes, which pose an immediate safety risk are repaired within 5 days. Less urgent ones are repaired within 21 days.

Our standard approach to repairing potholes is to saw cut, square, around the defect, creating neat joints. The area is then infilled with asphalt and sealed to stop water getting in.

Temporary 'make-safe' and emergency repairs

During winter or bad weather when surfaces are too wet or cold for permanent work crews may use a temporary repair. The repair is to make the area safe for a short time; the patches you see are not the final fix.

We use these temporary patches across the county when the roads keep freezing and then thawing.  We also use them in places where traffic is harder to manage.

These repairs are marked with a dot of yellow spray paint. Permanent repairs will be made when roadspace becomes available. This will usually be within 13 weeks of the 'make-safe' repair.

The Dragon Patcher

One of Cambridgeshire’s most distinctive pothole repair methods is the Dragon Patcher.

This is a machine that uses flames to dry and heat the damaged road, then cleans it with compressed air before sealing it with stone and bitumen.

  • It can repair a pothole in about three minutes.
  • It is five times faster than traditional methods.
  • It can mend up to 150 potholes a day.
  • Is cost effective because it operates without excavation.

The council operates at least two Dragon Patchers, and they have been used extensively in recent years, repairing hundreds of defects in a matter of days during peak damage periods. This helps us make roads safe until we are able to start patching or larger resurfacing work in the future.

The Dragon Patcher allows for a cost-effective quick application and sealing of the road surface, often without the need for traffic management. Once the repair is completed, the Dragon Patcher moves on, and the road is open for use. Occasionally, some loose chips may remain on the road from this type of treatment.

Patching

Alongside pothole repairs, the council also delivers patching work across the county.

This is where defects have been identified and repair is needed to extend the life of the road.

These repairs cover big areas of the road, not just single potholes. We often need to close the road so workers can do more work in each shift.

Quality

We are committed to ensuring the repair work we undertake is of sufficient quality. We have standardised approaches for how we repair potholes and undertake patching repairs which is aligned to national guidance and best practise. Our priority is always to deliver a right first-time repair where circumstances allow.

Where quality issues are identified, these are reported to our contractor for remediation within 28 days at their cost.

We randomly sample work delivered by our contractor and assess the quality of the repairs against agreed specifications.

Capital maintenance programme

Our capital maintenance programme delivers large-scale, high-value planned improvements to the public highway across Cambridgeshire. Most of the investment goes toward fixing defects before they turn into potholes.

Please visit our main capital maintenance programme page. This collection of pages outlines what type of maintenance and when it is being delivered in your area.

How we are improving highways maintenance

Over the past three years, we have made the biggest investment in the highways network in over a decade, and it is important to show you where your money is spent.

Visit how we are improving highways maintenance. This page outlines our priorities, what improvements were made in 2024/25, and funding allocation for 2025/26.

Pothole frequently asked questions

During winter, roads take a real beating. Water seeps into tiny cracks in the road surface, then freezes when temperatures drop.

As the water freezes, it expands, forcing the cracks wider. When it thaws, the surface is left weaker and repeated freeze–thaw cycles eventually cause pieces of road to break away and form potholes.

Add to that:

  • Heavy rainfall, which speeds up wear and tear
  • Traffic and heavy vehicles, which put extra pressure on weakened road surfaces
  • An ageing road network which has evolved over time, much of it built decades ago and not to modern design standards, that’s more prone to breaking up

This happens every year, but it is more noticeable after wet and cold spells, which is why pothole numbers tend to peak peak during winter or bad weather.

The good news is that this is exactly why we are increasing inspections and repair crews during winter and early spring, focusing first on the worst stretches of road to keep people moving safely.

If we placed all of Cambridgeshire’s roads end to end, they would stretch from the UK all the way to the east coast of America; around 2900 miles.

We are investing as much as we can in road maintenance whilst also maintaining our other highway assets such as footways and bridges. In the past three years we have invested an extra £20m each year in addition to that provided by government. Unfortunately, we do not have enough funding to resurface all Cambridgeshire’s roads to stop potholes from forming. This means potholes will still happen, and when they do we will fix them in line with our policies.

More information on the state of our roads can be found on how we are improving highways maintenance.

We don’t carry out repairs in heavy rain, but once a repair is finished, rain won’t affect how long it lasts.

The time it takes to fix a pothole can vary. Firstly, it depends on how the officers have assessed the risk. The assessment outcome means it could be repaired within 2hrs, 5 days, 21 days or 13 weeks.

Some locations are hard to plan for. Consent from other third-party organisations may be needed before we can do the work.

There may be other work already taking place on the network that we have to wait to be finished. If this happens, we will always try to work together with others. We may make temporary repairs in the meantime.

Repairing potholes is not planned work. So, if many appear at once, we may not have enough permanent staff to keep up. This means we have to bring in extra temporary resources to meet the demand, and this can take time. We use this approach to work in the most efficient way because demand changes throughout the year and from year to year.

Yellow markings show that a pothole has been inspected and recorded for repair.

Marking a pothole does not always mean it will be repaired immediately, but it confirms work has been scheduled.

When a pothole is assessed, officers will identify any problems. If it meets our investigation levels or is unsafe for road users, they will order the needed work.

For more information on our investigation levels, please visit how long does it take to fix a road fault.

This approach follows national guidance. It helps us prioritise highway maintenance so we can keep roads safe.

We also invest in work that helps stop potholes from forming. These include surface treatments and resurfacing roads across the county.

We will always look to minimise the impact of our work wherever possible and give users as much notice as we can. However, as we often need to deliver urgent repairs to address a road safety concern this is not always possible.

Wherever possible we will seek to deliver work when the network is not as busy, either overnight or during outside of peak hours, such as between 9.30 am and 3.30 pm.

We are seeing a very high level of demand from utility companies and developers for space on the road network including an unprecedented level of requests for permits in and around Cambridge. You can find out about upcoming works via our Roadwork and traffic information - Roadworks and faults page.

We carry out regular quality inspections on a minimum of 5% of our completed pothole repairs. A sample of repairs is checked, and if issues are found, the contractor must return and fix them at no additional cost to the Council.

It is important to remember that some repairs are only temporary, and these will be marked with a yellow dot.

In addition to the repairs our Highway Officers check, we also visit sites to ensure our contractors are completing work to the required standard.

Pothole repairs can fail for a number of reasons, our first priority when delivering a repair is to make the road safe.

A pothole repair isn’t the same as undertaking a complete structural repair which may require a deeper more expensive treatment under different traffic management arrangements over a longer period of time.

Some of the reasons a pothole repair might fail are:

  • Severe weather
  • Heavy traffic
  • Weak underlying road layers
  • Deterioration of the surrounding material

Please report the failed repair . We will reassess and re‑order work where needed. Making clear that you are reporting a failed repair helps us to identify places where there may be underlying issues with the road. 

Whilst we will inspect a minimum of 5% of our completed pothole repairs, we are unable to inspect them all. If you see a repair you think has failed please report it to us and we will assess and action accordingly.  

Our repair teams work in live traffic environments, often in difficult weather and under time pressure. You can help keep them safe by:

  • Respecting traffic management and temporary signals.
  • Being patient if works cause short delays.
  • Treating operatives with courtesy and kindness – they are there to keep the road safe for everyone.
  • Avoiding confrontation or abuse, whether in person or online.

Our crews are doing challenging work on behalf of the community. A moment of patience and understanding makes a real difference to their safety and wellbeing and ensures we can deliver the repairs as quickly as possible.

Information about making a claim is available on our Making a highways claim page.

Each claim is assessed individually, based on whether we met our inspection and repair duties at the time.

Our repair times as identified can be found on How long does it take to fix a road fault.
