Safe Non-Destructive Excavation

Hydro-vacuum excavation is a safe, effective process of excavating around underground obstacles such as optical-fibre, power and telecommunication services, and gas, water and sewer mains.

The process can also be used to expose these items to carry out repairs to them. It is fast becoming the preferred method of excavation in the construction industry

How Hydro-Vacuum Excavation Works

The truck is a self-contained unit. It uses pressurised water to break down the soil using high-pressure water while an industrial-strength vacuum pumps the removed soil and the water back into a holding tank.

This vastly reduces the risk to utilities caused by manual or mechanical digging methods and results in safe, fast, precise diggings that require less backfill, labour and restoration.  It has less environmental impact than traditional techniques; power, water, gas and sewer utilities remain unharmed by our high pressure water jetting.

Minimise Your Risk

No contractor wants to be the one responsible for a telecommunications or power outage because they damaged a cable. Ovac’s hydro-vacuum technique makes it easier to avoid causing damage to infrastructure.  

Ideal for Small Excavations

When you need to dig in a hard-to-reach spot, or bringing in a bigger machine is just overkill, Ovac is the perfect solution. 

Some typical uses for OVAC include:

  • Digging in tight, hard-to-reach spaces
  • Pot-holing
  • exposing utilities
  • trenching
  • cleaning of sites
  • mud and slurry removal
  • Post holes
