Hydro Excavation & Non-Destructive Digging
Pressurised water and industrial vacuum to expose or remove soil around live services.
Hydro excavation uses pressurised water and high-capacity industrial vacuum equipment to break up and remove soil while exposing underground infrastructure. It is a controlled, non-destructive method of digging that reduces the risk of striking live services compared with mechanical excavation.

Benefits of using Dynamic
Protects buried assets
Water and vacuum expose services without the blunt force of a bucket, lowering the chance of a strike.
Access where machines cannot reach
Long vacuum hoses let crews work in tight, offset or restricted locations that block conventional plant.
Clean, precise excavations
Neat verticals and controlled spoil removal suit potholing, service proving and works around existing infrastructure.
Backed by a large fleet
Multiple units across QLD and NSW support both single potholes and sustained programmes of work.

Frequently asked questions
What is hydro excavation?+
Hydro excavation is a digging method that uses pressurised water to loosen soil and an industrial vacuum to remove it, exposing or excavating around underground services with a lower risk of damage than mechanical digging.
Is hydro excavation the same as non-destructive digging?+
Hydro excavation is one of the most common forms of non-destructive digging (NDD). The terms are often used together because both describe methods that expose services without direct mechanical contact.
Can you work close to live services?+
Yes. Hydro excavation is regularly used to expose and prove services near live electrical, gas, water and communications assets. Works are planned using available utility plans and site information.
What happens to the spoil?+
Wet spoil is collected in the vacuum unit and can be transported for offsite disposal. Disposal arrangements are confirmed as part of your quote.

Hydro excavation as a risk control on civil construction sites
On a civil site the excavation method is a programme decision as much as a safety one. Hydro excavation is specified because it narrows the range of things that can go wrong at the point where a project is most exposed.
