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 200 feet from the truck, reaching spots an excavator never could.
Setting the standard in non-destructive excavation through uncompromising job site safety, pinpoint accuracy, and dependable response times.
Visual verification of underground utilities before you bore, drill or dig. We confirm exact depth and position so your locate marks become hard data.
Narrow, clean trenches for new conduit, cable, water and gas lines, dug alongside existing services without damaging them or the ground around them.
Excavation inside natural gas compressor stations and meter sites, where dense piping and live pressure leave no room for a mistake.
Safe exposure of transmission and gathering lines for inspection, repair and new connections, without the strike risk of a bucket near the pipe.
We dig the pits and expose every crossing along the bore path, so your drill crew can work knowing where each line sits.
Clean, accurately sized holes for poles, signs, fences and footings, dug safely in areas packed with buried utilities.
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.
We haul the slurry and spoils from every dig to an approved disposal site, so nothing is left behind on your job.
We can dig up to 200 feet horizontally from the hydro excavation truck and up to 12 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.
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.
| Hydro excavation | Backhoe / hand dig | |
|---|---|---|
| Strike risk | Very low | High near lines |
| Hole size | Only what's needed | Oversized cut |
| Spoils | Contained in truck | Pile on site |
| Hard-to-reach spots | Up to 200 ft from truck | Needs machine access |
| Restoration | Minimal | Extensive |
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.

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.
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.
Yes. Locates are required before any excavation. Potholing is how you verify those marks before you bore or dig.
Yes. Hydro excavation is well suited to live facilities. We work under the operator's safety program, permits and site-specific requirements.
Up to 200 feet horizontally and up to 12 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.
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.
