Hydro Excavation

Hydro Excavation is the process of using pressurised water to break down the earth’s soil, which is then vacuumed up.


We’ve seen and heard it all.

  • The fountain of sewer from a pump line no-one knew was there.
  • The power going out because the cable was supposed to be somewhere else.
  • Fibre-optic cables dangling from a digger bucket.



Our specialist equipment can help with the following:

  • “Potholing” to check for services along the thrusting route.
  • Exposing known services for repair, maintenance, or to lay new beside old.
  • Trenching around trees without damaging tree roots.
  • Trenching around transformers without damaging power cables.


Here’s a sample of our achievements on projects so far:


  • Excavated 70 Pile Holes in one day for a tricky house site.
  • Excavated 45 tonnes of gravel from behind a retaining wall, 80m away and 12m below the truck.
  • 50mm-wide trench to a depth of 350mm for broadband lead-ins.
  • Pot Holing and Excavating for the ultra-fast broadband roll-out in Napier, Auckland and Christchurch.
  • Excavated a large area to expose a coil of power cable at a substation.
  • If everyone says it can’t be done, call the innovators at HydroVac, we like a challenge.
