Twenty years ago Velocity pioneered spray-injection patching, an innovative technique used for corrective and preventative highways maintenance.
Velocity Patching permanently repairs potholes at a fraction of the cost of traditional techniques, with each machine capable of repairing up to 200 defects per day. Velocity Patching has become an established technique used by local authorities and maintenance contractors throughout the country.
As well as operating a fleet in the UK, Velocity design and manufacture the most advanced spray-injection patching machine for domestic customers and export globally.

What we do
Velocity carry out annual maintenance programmes for local authorities throughout the UK, using Velocity Patching to repair potholes, cracking, crazing, depressions and deformation, edge-deterioration and sealing conventional repairs.
Using a three-stage process, defects are cleared of debris using high-velocity air. A bituminous emulsion is then applied, again at high pressure, sealing any cracks and crevices to prevent water ingress. Finally, aggregate is coated in emulsion and applied at high pressure, compacting from the bottom up. Repairs take minutes to complete and are ready for traffic immediately.
The method costs less than a third of traditional techniques, and the cold-applied process delivers carbon savings in excess of 90%.
Velocity Patching is used throughout the road network, from single-track lanes to the busy urban streets of London.
An active contributor to industry standards, Velocity contributed to the development of the sector scheme NHSS 13 and sit on the British Standards Institute committee for the British Standard for Spray Injection Patching, BS 10947:2019.
