Spray Injection Patching

Spray Injection Patching is a fast and cost-effective method for repairing potholes, cracks, and other pavement defects in fraction of the time that it would take with more conventional methods of road repair. Following our philosophy of self-delivery, EST offers this unique process with our own fleet of spray injection patching machines and trained operators.

The process is mainly applied within the rural road network, however Eurovia's material technology also allows works to be completed in urban areas.

So how does it work?

Assessment: Our experienced teams first complete a full assessment of the condition of the pavement identified for treatment.

Preparation: The defect is thoroughly cleaned, removing debris and other loose material by blasting high pressure air into the defect. The defect is then sealed with a cold applied emulsion.

Spray Injection: The system then injects a blend of bitumen emulsion and graded aggregate into the defect. This high-pressure injection fills cracks and voids while bonding the patch to the existing pavement.

Compaction: The injected material is then compacted to ensure a seamless, blended, level surface with the existing pavement.
The whole process can take as little as 2 minutes to complete.

The Spray Injection Machine

Our purpose-built 7.5 cubic metre Spray Injection Machines are uniquely designed to be a self-contained unit reducing the need for additional support vehicles while on site.

The machine includes a hopper for the aggregate, an emulsion storage tank, an independent donkey engine, space for the whacker plate and the spray arm where the operation is controlled.

The benefits

Spray Injection Patching is offered as a permanent repair, as the emulsion is forced in cracks, preventing the ingress of water and further deterioration.

It's an efficient and cost-effective solution with the average repair cost being only a fraction of a conventional hot applied permanent repair.

The cold applied bitumen emulsion reduces CO2, when compared to conventional techniques.

It reduces waste, with zero waste going to landfill.

Its speed minimises disruption to traffic.

The process significantly increases the amount of defective pavement that can be repaired in a single shift, when compared with more conventional repair techniques.
