ACTI-VAC · HYDRO EXCAVATION
Hydro excavation, done right.
Acti-Vac is the hydro-excavation sister company of Always Active Services — safe, precise, non-destructive digging around the utilities you can't afford to hit, across the greater Seattle area.
THE METHOD
What is hydro excavation?
Hydro excavation uses pressurized water to break up soil and an industrial vacuum to remove the slurry — digging without a bucket or blade ever touching the ground.
That makes it the safest way to work around buried gas, water, electrical, and fiber lines. It's precise enough to spare tree roots, leaves no stockpile of spoils behind, and keeps congested or sensitive sites clean and code-compliant.
