What is Hydro Excavation?

Hydro excavation is a non-destructive digging method that uses high-pressure water to break up soil, while a vacuum excavation system simultaneously removes the debris into a holding tank. This means no heavy machinery tearing up your property, and no risk of damaging pipes, cables, or other underground infrastructure.

It’s the safest, cleanest, and most efficient way to dig – ideal for plumbing and drainage work, utility installation, potholing, trenching, and exposing underground services.
