Hydro Excavation Services

What is Hydro Excavation?

Hydro excavation is a specialised digging method that combines high-pressure water with a powerful vacuum system to remove soil. The water is directed into the ground to break apart and loosen soil, while the vacuum immediately extracts the slurry into a sealed debris tank.

Because the process uses water instead of mechanical force, it significantly reduces the risk of striking or damaging underground services. The precision of the technology makes it especially valuable in congested urban environments or on projects where accuracy is critical.

In simple terms, hydro excavation provides a way to dig with control, speed, and safety, making it a preferred choice for industries that need non-destructive excavation.

Benefits of Hydro Excavation Services

Our investment in hydro excavation technology means we can deliver a range of benefits to our clients:
