The choice for Canterbury projects
When you need to expose underground services or dig in tight spaces without the risk of damaging infrastructure, Robsons’ hydro excavation services are the gold standard. Operating out of our Hornby and Rakaia yards, we provide Canterbury’s most reliable vacuum excavation solutions.
What is Hydrovac
Hydro excavation (often called Hydrovac) uses high-pressure water to loosen the soil, which is then
immediately removed by a powerful vacuum.
The non-invasive nature of Hydro Excavation reduces the need for large-scale site disruption, Operators can work in tight spaces, perform tasks like potholing (exposing utilities for inspection), and dig precisely around critical infrastructure without damage.
Hydro excavation is suitable for a variety of applications, from trenching and daylighting to general excavation.
