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.
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.

Why Crews Rely On Our Potholing Services
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.
