Plant digs in Corpus Christi
Hydrovac digs inside refineries, petrochemical plants and terminals, where underground piping is dense and the site's rules come before the dig.
A quote-request service, not a contractor. We pass your request to independent local operators who quote you directly.
What plant digs cover
Refinery and petrochemical maintenance crews are among the usual buyers of hydrovac work around Corpus Christi. Inside a plant, a lot of piping and cable sits close together underground, and a hydrovac digs without a bucket.
Typical requests
- Test holes before foundation, pipe-support or equipment work
- Exposing a process or utility line before a repair or tie-in
- Digging around an underground valve or vault for inspection
- Clearing a path for a new line inside an operating unit
- Trenching for conduit or cable inside the fence
- Digging support during a turnaround, when many crews share a unit
This page covers excavation. Other plant work, such as cleaning or hydroblasting, is not something we can promise; describe it under Other / not sure in the form and operators will tell you whether they do it.
Why vacuum inside a plant
No steel on the pipe
Water loosens the soil and the vacuum lifts it out, so no bucket teeth or shovel blades touch pipe, coating or cable. That is why plant owners often specify it near underground lines. Ask your facility for its rule.
Air excavation
Some operators also run air excavation, which keeps the spoil dry and puts no water around sensitive pipe. Ask which operators have it.
Plant soil
Where soil from inside a plant may go is set by the facility and by what is in it. Ask the facility, and tell operators what you know before they price disposal.
When plants call for a hydrovac
- During a turnaroundMany crews share a unit in a short window. Send the request early and give operators the schedule.
- Before foundation or support workTest holes show what is in the way before anything is set or driven.
- Near private linesTexas 811 member utilities mark their own lines. A plant's process piping and cable are private, so start with plant drawings and a private locate, then test holes.
- Near live pipingMany plants require vacuum or hand digging within a set distance of piping. Ask the owner for the rule.
- Along a pipeline corridorLines that leave the plant are covered on pipeline exposure.
Plant rules come first
Plants commonly set these on top of Texas 811. Requirements differ by site, so this is a list of what to ask, not what any one plant requires.
| A site may require | Ask the operator |
|---|---|
| Site orientation or contractor onboarding | Can your drivers and crew complete it before the start date? |
| Safety pre-qualification | Is the company already pre-qualified, or can it apply? |
| Insurance certificates | Can they supply the certificates the site asks for? |
| Work permits | Will the crew follow your permit-to-work process, and who signs? |
| Badging and escorts | Who arranges badges, and will an escort be needed? |
| Driver and crew checks | Ask about CDL drivers, clean driving records and drug and background screening. Job postings for local operators list these. |
What to have ready
Operators price faster, and closer to the final bill, when these are in the request.
- The unit or area, with a drawing marking the dig and nearby piping
- Any private locate results, and your Texas 811 ticket number if one applies
- Your permit-to-work process and who signs
- Onboarding steps, badging and escort arrangements
- Work hours, the gate and a route a truck can use
- Number of holes or length of trench, depth and surface
- Disposal rules for plant soil
- A site contact who can approve the dig
811, pipelines and permits
Texas 811
Excavators generally must notify Texas 811 at least 48 hours before digging, not counting weekends and legal holidays. The call is free. If your job runs long, the ticket can expire: check the current rules and renew before it does. Private lines inside the fence are not marked by 811 member utilities, so plan for a private locate.
Pipelines
If a pipeline is damaged in any way, the excavator must notify the pipeline operator and Texas 811. Stop work near the damage and keep people back.
Facility rules
Facility rules sit on top of state law: orientation, safety pre-qualification, insurance certificates and work permits. The operator you hire has to meet them, so put them in the request.
Port terminals
We have not confirmed contractor rules for Port of Corpus Christi terminals. Ask the terminal what it requires, and put the answers in your request.
Plant dig questions
Can hydrovac operators work inside a refinery?
Many hydrovac operators here do plant and terminal work, but every facility sets its own contractor rules. Tell us in the form if your site has onboarding, and confirm it with each operator before you hire.
What will a plant ask a contractor for?
Commonly orientation, safety pre-qualification, insurance certificates, work permits and badging. Each site sets its own list, so ask your facility for it and pass it to the operators.
Do I need an 811 ticket inside a plant?
Texas 811 notice applies to excavators in general: at least 48 hours before digging, not counting weekends and legal holidays. Your facility may also have its own dig permit process, so confirm with it what applies inside the fence.
Can you do hydroblasting or tank cleaning?
This service is excavation only. We have not confirmed that operators offer cleaning or hydroblasting, so we do not list it. Describe the work under Other / not sure and ask operators directly.
What does a plant dig cost?
Published guides put hydrovac work at roughly $200 to $450 an hour, and day rates around $3,500 to $4,500, as typical market ranges. These are not our rates, and operators can quote outside them. On plant jobs, ask what a day rate includes: time at the gate, orientation, standby and debris-tank dumps.
