Frequently Asked Questions
What is Hydro Excavation / NDD?
Non-Destructive Digging (NDD), also known as Hydro Excavation, uses high-pressure water and a vacuum system to safely expose underground utilities without damaging them. It’s a safer and more precise alternative to mechanical digging.
Why use NDD instead of traditional excavation?
Hydro NDD dramatically reduces the risk of damaging buried services like gas, water, power, or comms. It’s cleaner, safer, more precise, and ideal for sensitive or built-up areas.
What can Hydro Excavation be used for?
Common NDD applications include:
- Utility location and potholing
- Excavation around tree roots or heritage sites
- Service trenching
- Pit and pole hole digging
- Drain and sewer maintenance
- Vacuum loading of debris
Where do you offer Hydro NDD services?
We service all areas of Melbourne, Victoria. Contact us to confirm if we can reach your site.
Is NDD safe around utilities?
Yes — Hydro Excavation is specifically designed to protect underground assets during digging. It’s the preferred method used by councils, utility providers, and Tier 1 contractors.
How long does NDD take compared to mechanical digging?
While site conditions vary, Hydro NDD is often faster overall due to reduced reinstatement and risk. You avoid time-consuming delays caused by damaging services.
Is NDD more expensive than traditional digging?
Upfront costs can be slightly higher, but the reduction in risk, delays, and repair costs makes Hydro NDD more cost-effective for many projects.
What happens to the slurry and debris?
All excavated material is vacuumed into our onboard tanks and safely disposed of at licensed facilities. We leave the site clean and compliant.
Do you provide compliance documentation?
Yes. We can supply SWMS, risk assessments, EPA waste tracking, and asset protection reports upon request. We’re fully licensed and insured.
What size jobs do you take on?
From small residential potholing jobs to large-scale civil and infrastructure projects, we’ve got the gear and experience to handle it.
