Road preservation
Road preservation is a proactive treatment that protects road surfaces from ageing and deterioration.
The specific benefits are that it:
- is a cost-effective preventative treatment, applied early in a road’s life to seal micro-cracks and small voids
- prevents potholes by providing a waterproof seal that stops water entering and damaging the surface
Preservation works are typically carried out between April and September, as the process requires warm and dry weather
Before we start
Advance warning signs (yellow) will be placed on affected roads at least seven days before work begins.
Residents on roads due to be treated will receive information explaining what to expect.
If you need vehicle access during the day, please move your vehicle to another location before works start.
During the works
To ensure safety, we use traffic management such as road closures, convoy systems, or stop/go boards.
The surface can take between 1-2 hours to cure fully before being suitable for traffic.
Please avoid walking or driving through wet bitumen. It can stick to shoes, tyres and surface such as driveways and carpets.
After the works
The site will be cleared and cleaned, and the traffic management will be removed as soon as it is safe to do so.
The treatment may make the road surface appear darker or different in colour immediately after application. This is normal and part of the preservation process, which helps protect and extend the life of the road. Over time, as the surface is exposed to traffic and weather, it will lighten gradually and settle into its final appearance, blending naturally with the surrounding road.
Road markings will be repainted as soon as possible.
Weather and scheduling
Road preservation can only take place in dry conditions. If the weather changes or rain is forecast, works may need to be rescheduled at short notice to ensure quality and safety.
