NON DESTRUCTIVE DIGGING
Safe, Precise Vacuum Excavation
Across Warrnambool & Western Victoria
Hydro Excavation Experts
Complete Underground provides professional hydro excavation and vac truck services for civil contractors, utility companies, councils, and developers throughout Warrnambool and Western Victoria.
We specialise in non-destructive digging (NDD) to safely expose buried services, trenches, and pits without damaging existing infrastructure.
Whether you're working near high-voltage lines, telecoms, water mains or fibre optic networks, our hydro vac crews are trained to work safely and efficiently — with minimal surface disruption and maximum accuracy.
WHY USE HYDRO EXCAVATION?
Hydro excavation (also known as vacuum excavation or NDD) uses high-pressure water to break up soil and a vacuum unit to remove debris. It’s ideal for:
​
-
Exposing underground utilities before drilling or trenching
-
Excavating around live electrical, gas, comms or water assets
-
Potholing and service location
-
Slot trenching for conduit installation
-
Working in tight or built-up urban environments
-
​
This technique reduces the risk of damaging critical services and eliminates the need for hand digging.
How It Works
Hydro excavation is a low risk, cost effective form of excavation. Hydro excavation significantly reduces the risk of damaging existing underground assets as traditional mechanical excavation practices are alleviated.
​​
A combination of Vacuum & pressurised water. The pressurised water breaks up existing soils which allows the vacuum to remove the soils in a timely manner. The soil is stored in our vacuum tank and removed from site, leaving less mess.

Frequently Asked Questions (FAQs)
Q: What’s the difference between hydro excavation and traditional excavation?
A: Hydro excavation is safer and more precise. It uses water and suction rather than mechanical digging, making it ideal for working near live services.
​
Q: How much does vac truck hire cost?
A: Rates depend on location, duration, and site conditions. Contact us for a customised quote.
​
Q: Can you dig in tight or hard-to-reach areas?
A: Yes — our trucks have long hose reach and are ideal for backyards, narrow driveways, and other restricted access zones.
