Bunney’s Inc. delivers safe, precise vacuum excavation for utility, telecom, and industrial sites across Arizona. We use non-destructive methods—air-vac and hydro-vac—to expose underground assets, install small trenches, and clean structures with minimal surface disruption and maximum job-site safety.

What We Do
Utility Daylighting & Potholing
Expose buried utilities to verify depth and alignment before trenching or duct bank work.
Slot Trenching & Service Cuts
Narrow, accurate trenches for new drops, small conduits, and conduit excavation tie-ins.
Debris & Structure Cleaning
Wet/dry vacuum for valve boxes, meter pits, catch basins, and vaults.
Backfill & Restoration
Select backfill or CLSM, compaction to spec, and surface repair (asphalt or concrete flatwork).
Need precise utility confirmation without damage? See our Potholing Services and Hydro Excavation pages.
Air-Vac vs. Hydro-Vac: Choosing the Right Method
-
Air-Vac (dry): Uses compressed air to loosen soil, vacuuming it into the tank. Great for reusable spoils and when water introduction is a concern (e.g., electrical corridors).
-
Hydro-Vac (wet): Uses pressurized water to cut through hard or compacted soils efficiently—ideal for caliche/hardpan and fast production rates.
We’ll recommend the method based on soils, utilities present, environmental limits, and restoration needs.
Benefits of Vacuum Excavation
-
Non-destructive precision: Reduce utility strikes and rework.
-
Smaller, cleaner footprints: Faster restoration and less traffic disruption.
-
Safer operations: Fewer manual digs and clearer sightlines around live utilities.
-
Regulatory alignment: Supports permit, SWPPP, and inspection requirements (pair with Erosion Control where needed).
Our Process
-
Plan & Locate — Review plans, coordinate 811, map utilities, and set traffic control.
-
Expose & Verify — Air-vac or hydro-vac to daylight utilities and confirm elevations.
-
Excavate & Clean — Complete slot trenches or structure cleaning as scoped.
-
Backfill & Restore — Replace/reuse spoils or CLSM; compact and restore surfaces.
-
Document & Close — Provide photos, measurements, and notes for your records.
FAQs
Will vacuum excavation damage existing utilities?
It’s designed to avoid damage. We use controlled air or water, safe standoff distances, and trained operators around marked facilities.
Can you work in active ROW or within facilities?
Yes. We phase work with traffic control and coordinate with operations to maintain access.
What happens to spoils after excavation?
Air-vac spoils can often be reused; hydro-vac slurry can be managed, processed, or disposed per permit and owner requirements.
Do you handle restoration after potholing?
Yes. We backfill to spec, compact, and perform asphalt or concrete restoration as required.
