What is hydrovac excavation—and why it’s safer
Hydrovac (vacuum) excavation uses a controlled stream of pressurized water to loosen soil while a high-powered vacuum removes the slurry. The result is precise daylighting and trenching with far lower risk of utility strikes than mechanical methods—ideal for congested corridors, plant sites, and sensitive rights-of-way.
- Uses pressurized water to break up soil while a high-powered vacuum removes the slurry—precise, non-destructive excavation.
- Dramatically lowers utility-strike risk, reducing outages, claims, and rework.
- Ideal for daylighting and slot trenching in congested corridors, plant sites, and tight rights-of-way.
- Minimal surface disruption to pavement, hardscape, and landscaping; smaller cuts and patches.
- Cleaner spoils control—slurry is contained in the debris tank, reducing tracking, dust, and cleanup.
- Safer work zones with less hand digging and fewer pinch points; supports OSHA/permit compliance.
- Faster restoration and shorter traffic impacts thanks to narrower trenches and targeted excavation.
- Environmentally friendly approach that limits root disturbance and helps with SWPPP compliance.
- Tunable to Arizona soils (caliche, compacted fill); water pressure adjusted to conditions.
- Improves accuracy and documentation by exposing exact utility locations and depths for as-builts.
Where hydrovac excels
-
Utility locating & daylighting: Expose gas, water, electric, fiber, and telecom safely.
-
Slot trenching: Narrow, accurate trenches for conduit, small-diameter pipe, and test leads.
-
Potholing & pole holes: Confirm depths and clearances before setting structures.
-
Debris & sump cleaning: Remove ballast, silts, and non-haz solids from vaults and catch basins.
-
Plant & industrial maintenance: Precise excavation around live systems and foundations.

Our hydrovac process
-
Pre-plan & utility coordination – scope review, locates, and traffic/site controls.
-
Controlled excavation – water pressure tuned to soils; debris vacuumed into sealed tanks.
-
Spoils management – on-site containment or haul-off per project and jurisdictional rules.
-
Backfill/restore (as scoped) – flowable fill or engineered backfill, plus surface protection.
-
Close-out – photos, quantities, and daily reports for your records.

FAQs
What projects benefit most from hydrovac?
Daylighting utilities, slot trenching for conduit, clearing around live facilities, and any excavation inside congested or high-risk zones.
Is hydrovac faster than mechanical digging?
On sensitive sites, yes. Avoiding utility damage, permits for emergency repairs, and surface restoration typically shortens the overall schedule.
How deep can you hydrovac?
Depth depends on soil, groundwater, and access. Typical production depths range from a few feet to 15+ feet; deeper work is scoped case-by-case.
What happens to the slurry/spoils?
Material is contained in the debris tank and either reused (when allowed) or hauled to an approved facility per local requirements.
Do you handle traffic control and permits?
Yes. We can coordinate MOT/traffic control, right-of-way permits, and site-specific safety plans as part of our scope.
Do you offer emergency response?
We support urgent needs and outage work. Share your timeline, and we’ll advise on the fastest safe mobilization.
