When road maintenance involves working with high voltage cables, vacuum excavation provides a safe, smart way to excavate around live electricity.
Whilst working in London in our suction excavation expertise was called on to do just that – clearing ground to expose HV cables for essential maintenance work. The use of a vacuum excavator is a great alternative to mechanical diggers, as the softer suction power provides precise mining.
An added benefit of the vacuum excavator is the built-in skip, capable of holding up to 8m³ of excavated material. More times than not this means cable exposing can completed in one go without needing to stop to empty during the procedure. Excavated material is then stock piled on-site to reuse after maintenance is complete.
