Trusted Excavation Solutions Built for Arizona

Utility Potholing

At Arizona Professional Excavating, we deliver excavation services that combine over 35 years of experience with state-licensed precision. Whether you’re building, trenching, grading, or preparing for infrastructure, our team ensures every dig meets your project’s demands while complying with Arizona’s strict construction standards. Reliability starts with how we break ground.

Potholing That Prevents Utility Strikes & Downtime

Arizona Professional Excavating offers utility potholing services designed to locate and expose underground infrastructure prior to excavation or construction. Using hydro excavation, we dig narrow holes to uncover utilities without damaging them — keeping crews safe and projects compliant.

We work with engineers, contractors, municipalities, and utility companies to verify line depth, condition, and alignment. Our potholing methods support mapping, engineering redesigns, and pre-excavation safety protocols for any type of utility system.

What Our Potholing Services Include

Our field-tested approach ensures buried utilities are exposed cleanly, quickly, and with full documentation for construction teams, utility providers, or inspectors. We use non-destructive hydro excavation techniques to safely access gas, water, electric, and telecom lines, regardless of depth or location. Each pothole is carefully measured, photographed, and mapped to confirm alignment with engineering plans and locate marks. This method helps prevent costly utility strikes and provides peace of mind before excavation, boring, or foundation work begins. Whether it’s a new development, retrofit, or emergency response, our potholing service sets the standard for safety and accuracy.

Potholing Saves Time, Money & Lives

Blind excavation risks rupturing gas lines, cutting fiber optics, or damaging critical infrastructure. Our potholing services protect lives and equipment while preventing costly delays, emergency shutdowns, or rework.

Engineering & Design Validation Pre-Excavation Safety Measures Support for Emergency Locates

We use potholing to expose underground utilities ahead of construction, verifying that actual line locations match engineering drawings and site plans. This step helps identify discrepancies early, allowing design teams to adjust trench paths, equipment placement, or structure layouts before full excavation begins. It prevents project delays and costly rework.

  • Line depth checks

  • Utility reroute planning

  • Design corrections

Potholing provides a critical layer of safety before any mechanical excavation starts. By exposing utilities in advance, we protect workers from unexpected line hits and reduce liability on the job site. It’s a proactive measure that clears dig zones, confirms utility locations, and ensures regulatory compliance with dig alert requirements.

  • Crew safety protection

  • Dig area clearance

  • Regulatory compliance

In emergency scenarios such as gas leaks, service interruptions, or unmarked infrastructure, our hydro excavation crews respond quickly to locate and expose critical utilities. We help isolate the issue, confirm the exact point of failure, and provide access for repair teams — all while minimizing damage to surrounding systems.

Our Potholing Workflow For Safe Digging Zones


Our potholing workflow is designed to ensure maximum safety and accuracy before any major excavation begins. We start by reviewing utility maps, coordinating with dig alert services, and marking the exact locations of underground lines. Using hydro excavation, we carefully expose these utilities without damaging them, allowing for visual confirmation and documentation. Each pothole is measured, mapped, and photographed to support engineering decisions, redesigns, or compliance needs. This meticulous process helps eliminate the risk of utility strikes, protects crew members, and streamlines construction by confirming safe zones before mechanical digging takes place.

Frequently Asked Questions

What’s the difference between potholing and hydro excavation?
Hydro excavation is the method; potholing is the application. We use hydro excavation to expose specific points along buried utility lines.
Is potholing required before every dig?
It’s not always required, but it’s highly recommended (and sometimes mandated) when working near known or suspected underground utilities.
How deep can you pothole?
We can safely pothole down to 20+ feet, depending on soil conditions and site accessibility.
Do you provide maps or reports after potholing?
Yes. We can supply photos, depth logs, and rough utility sketches to help with engineering or permitting.
