The machine is made by road repair firm Velocity, who say the patching process ‘takes just a couple of minutes’ and does not involve excavation, waste, or heat.
The cross-party group London Councils said the machine had achieved a ‘record breaking’ 120 repairs in one day across Redbridge, and nearly 2,200 pothole repairs during a 12-week trial.
London Councils said the capital’s boroughs were facing a £1.59bn highways maintenance backlog.
Redbridge council leader Jas Athwal said: ‘Potholes are a nuisance and a danger to road users, and we understand how difficult they can make journeys around Redbridge.
‘We’re working hard to find innovative and cost-effective ways to improve road surfaces for local people.
‘The spray injection patching machine is helping pave the way, and where suitable we hope to continue using it on our roads, alongside our resurfacing programme and traditional repairs, enabling a greater number of potholes repairs to be completed faster across the borough, with fewer carbon emissions.’
