Cornerstone Industrial Services LLC
Hydro excavation · Potholing · Trenching

Dig safe around what's buried.

Cornerstone Industrial Services uses pressurized water and high-powered vacuum to expose lines, cut trenches and excavate around live gas facilities without the strike risk of a bucket. We can dig up to 450 feet from the truck, reaching spots an excavator never could.

What we do

Every dig. Done right.

From a single test hole to a full integrity dig, every crew knows the work cold. Each job is dug by hand-held wand and vacuum, with spoils hauled off in the truck's debris tank.

Test holes · Daylighting

Potholing

Visual verification of underground utilities before you bore, drill or dig. We confirm exact depth and position so your locate marks become hard data.

  • Depth & position verification
  • Keyhole and SUE test holes
  • Pre-bore crossing checks for HDD
Slot & line trenching

Utility Trenching

Narrow, clean trenches for new conduit, cable, water and gas lines, dug alongside existing services without damaging them or the ground around them.

  • Slot trenching for conduit & fiber
  • Digging in congested utility corridors
  • Minimal surface restoration
Midstream · Live facilities

Compressor Station Excavation

Excavation inside natural gas compressor stations and meter sites, where dense piping and live pressure leave no room for a mistake.

  • Exposing piping for inspection & tie-ins
  • Digs around grounding & cathodic systems
  • Work within operator safety programs
Pipeline · Integrity

Pipeline Excavation

Safe exposure of transmission and gathering lines for inspection, repair and new connections, without the strike risk of a bucket near the pipe.

  • Integrity & anomaly digs
  • Exposing pipe for coating repair
  • Tie-ins and line crossings
HDD support

Directional Boring Support

We dig the pits and expose every crossing along the bore path, so your drill crew can work knowing where each line sits.

  • Entry, exit & tracking pits
  • Exposing crossings along the bore path
  • Drilling fluid cleanup
Poles · Posts · Piers

Pole & Post Holes

Clean, accurately sized holes for poles, signs, fences and footings, dug safely in areas packed with buried utilities.

  • Utility & light pole holes
  • Sign, fence & guardrail posts
  • Pier and footing holes
Vacuum services

Valve Box & Pit Cleanout

We vacuum dirt, gravel and debris out of valve boxes, curb boxes, meter pits and vaults so crews can reach and operate what's inside.

  • Valve & curb box cleanout
  • Meter pits and vaults
  • Catch basins and small sumps
Haul-off · Disposal

Slurry Disposal

We haul the slurry and spoils from every dig to an approved disposal site, so nothing is left behind on your job.

  • Slurry hauling & approved disposal
  • Spoils removed from site
  • Debris tank emptied off-site

Remote digging

Where an excavator can't go, our hose can.

We can dig up to 450 feet horizontally from the hydro excavation truck and up to 45 feet vertically. That reaches spots no excavator can get to: behind buildings and fences, inside tight station yards, under pipe racks, and across soft or sensitive ground where heavy equipment can't drive.

  • Up to 450 ft horizontal, 45 ft vertical
  • No machine access needed at the dig
  • Truck stays on the road or pad
Why hydro excavation

Water cuts the soil. The vacuum does the lifting.

Marks on the ground aren't always right. Hydro excavation lets you see what's actually down there, without the risk of cutting into it.

Who we are

Owners on the job, not behind a desk.

Cornerstone is run by the people who started it. You deal directly with an owner from the first call to final cleanup, which means faster answers and a crew that is accountable for every hole it digs.

How a job runs

From call to clean site

1

Send the scope

Tell us the location, what needs exposing or trenching, and your timeline. We send back a clear quote.

2

Locates & plan

We confirm 811 tickets and review drawings and site rules so the crew arrives with a plan.

3

Dig

Water and vacuum open the hole or trench. We report depth and position of every line we find.

4

Clean up

Spoils leave in the truck, the work area is left clean, and you get the job details.

Safety

Safety sets the pace

Add: prequalification (e.g. ISN / Veriforce / Avetta) Add: OQ / safety certifications
  • Job safety analysis every day. Hazards are reviewed with the crew before the first cut.
  • Trained operators. Crews know how to work around live gas, electric and fiber.
  • Your rules on your site. We follow operator procedures, permits and PPE requirements.
  • Stop-work authority. Anyone on the crew can stop the job if something looks wrong.

FAQ

Common questions

Don't see yours? Call Aaron or Doug, or send the scope and we'll answer it with your quote.

What is hydro excavation?

A digging method that uses pressurized water to break up soil and a powerful vacuum to lift it into a sealed debris tank on the truck. Because nothing hard touches the line, it is the safest way to expose buried utilities.

What's the difference between potholing and trenching?

Potholing is a small test hole to see a line's exact depth and location. Trenching is a longer, narrow cut to install or reach a line along its length. We do both with the same equipment.

Do I still need an 811 locate?

Yes. Locates are required before any excavation. Potholing is how you verify those marks before you bore or dig.

Can you work inside an active compressor station?

Yes. Hydro excavation is well suited to live facilities. We work under the operator's safety program, permits and site-specific requirements.

How far from the truck can you dig?

Up to 450 feet horizontally and up to 45 feet vertically. We run hose from the truck to the dig site, so we can excavate behind buildings, inside fenced yards, under pipe racks or on ground an excavator can't reach or drive on.

What happens to the dirt?

It goes into the truck's debris tank and is hauled off for proper disposal, so there's no spoil pile left on your site.
