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.
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
