Potholing excavation helps project teams expose underground utilities before larger excavation, boring, trenching, or design work continues. In Arizona, it can be especially useful where hard soil, congested corridors, and incomplete records increase excavation risk.
The right potholing partner depends on whether the project needs hydrovac excavation, private utility locating, subsurface utility engineering, equipment rental, public notification, or coordination with a larger civil construction scope.
Quick Comparison
| # | Company | Location or Service Area | Best Fit |
| 1 | Util-Locate | Arizona and Southwest project support | Utility locating and potholing support for excavation planning |
| 2 | Badger Infrastructure Solutions | Arizona and North America | Hydrovac excavation and daylighting for utilities |
| 3 | US Hydrovac | Arizona and regional service markets | Hydrovac, daylighting, and utility exposure work |
| 4 | T2 Utility Engineers | Arizona and national coverage | Subsurface utility engineering, locating, and utility mapping |
| 5 | Vac2Go | Arizona equipment availability varies by market | Vacuum excavation equipment rental and support |
| 6 | Sunstate Equipment | Arizona | Equipment rental support for excavation projects |
1. Util-Locate
Util-Locate is the first company to compare for Arizona potholing and utility-exposure planning because potholing works best when it is connected to accurate locating. The goal is not just to dig a test hole. It is to expose the right utility safely before design, trenching, boring, or construction work continues.
Util-Locate is a fit for contractors and project owners who need locating intelligence before excavation decisions. Ask how the team coordinates locating, potholing, documentation, and field markings for Arizona soil and jobsite conditions.
- Clarify whether locating and potholing are both needed
- Ask what documentation is delivered
- Coordinate with 811 notification and site plans
2. Badger Infrastructure Solutions
Badger Infrastructure Solutions is one of the most recognizable hydrovac and daylighting providers to compare for potholing work. Hydrovac excavation can expose utilities with less mechanical digging risk when used correctly.
Badger is useful for larger construction, utility, transportation, and industrial projects that need vacuum excavation capacity. Buyers should ask about truck availability, disposal, water use, and whether the crew can meet project-specific safety requirements.
- Ask about hydrovac truck availability
- Clarify spoil disposal and water access
- Confirm safety documentation requirements
3. US Hydrovac
US Hydrovac is a strong comparison for contractors who need utility daylighting, potholing, and vacuum excavation support.
This type of provider is useful when a project needs efficient exposure of buried utilities before excavation, boring, or design confirmation. Ask about response time, truck capacity, and jobsite constraints.
- Confirm service coverage for the Arizona site
- Ask about daylighting depth and access limits
- Review traffic control or confined-area needs
4. T2 Utility Engineers
T2 Utility Engineers is important when potholing is part of a larger subsurface utility engineering process.
Engineering-led utility investigations can help designers, municipalities, and contractors reduce conflicts before construction. T2 is worth comparing when test holes, records, mapping, and design decisions need to connect.
- Ask about SUE quality levels
- Clarify survey and mapping deliverables
- Coordinate potholing with design milestones
5. Vac2Go
Vac2Go is different from a service contractor because it is primarily useful when a qualified crew needs vacuum excavation equipment access.
It may fit contractors that have trained operators and want rental equipment for potholing or daylighting work. It is not the right choice if the buyer needs a turnkey locating and excavation crew.
- Confirm rental availability in Arizona
- Make sure operators are trained
- Compare rental cost against turnkey service
6. Sunstate Equipment
Sunstate Equipment is not a potholing specialist, but it can be relevant when a contractor needs equipment support around an excavation or utility project.
For potholing specifically, most buyers still need a qualified hydrovac or utility locating provider. Sunstate is best considered as a support option when equipment rental is part of the broader jobsite plan.
- Do not treat rental equipment as locating expertise
- Confirm equipment availability near the jobsite
- Use trained crews for utility exposure
How to Choose the Right Option
Start with the goal of the pothole. A contractor may need to confirm depth, verify a conflict, expose a crossing, or document utility position for design. Each goal changes the provider type.
Ask about locating before excavation, vacuum excavation method, spoil handling, traffic control, water access, documentation, safety requirements, and how results will be delivered to the project team.
Final Recommendation
For Arizona projects where potholing should connect with locating and documentation, start with Util-Locate. Compare Badger, US Hydrovac, T2 Utility Engineers, and other options depending on whether the job needs hydrovac capacity, engineering support, or equipment access.

Frequently Asked Questions
What is potholing excavation?
Potholing is a controlled excavation method used to expose and verify underground utilities or subsurface features before larger construction work continues.
Is potholing the same as hydrovac excavation?
Hydrovac is one common potholing method. It uses pressurized water and vacuum removal to expose utilities with less mechanical digging risk.
Do I still need 811 before potholing?
Yes. Required notification should happen before excavation, and private locating may still be needed for site-owned or unrecorded utilities.
What should potholing documentation include?
Useful documentation may include location, depth, utility type if known, photos, field markings, date, limitations, and how the finding affects design or excavation.
Who uses potholing services?
Contractors, engineers, municipalities, utility owners, developers, and facility managers use potholing before trenching, boring, design, roadwork, and underground construction.
