Cornerstone Excavation Group does trenching in Indian Trail and across the Charlotte metro. We dig the trench for whoever sets the line, like an electrician running conduit to a detached garage. The trade, the plan or the utility sets the depth and route, and we dig to it. The trench stays open for the inspection, and then we backfill it and put the yard back.
Cornerstone is 5.0-rated on Google and based in Indian Trail, on the east side of Charlotte. We work the Charlotte metro, Union County and the York County side of South Carolina. A full water, sewer or storm system built to a plan is utility installation work. Call (980) 315-5707 for a free estimate after an on-site look.

Running power underground to a shop, pool equipment, a standby generator or an EV charger starts with a trench. Most electricians do not dig those trenches themselves. They hire out the trenching, then set the conduit and pull the wire. We dig the run on the route the electrician marks.
Plumbers and the gas company need trenches too, for a water service, a sewer lateral or a gas line. We dig to their route and depth and hold the trench open until they finish.
For builders and general contractors, we dig footing trenches and utility trenches on new lots. On commercial sites we trench for fiber and telecom conduit and for drain lines. A French drain system is yard drainage work. Digging a full house foundation falls under foundation excavation.
Every job starts with the locates. North Carolina law calls for notice to NC811 at least three full working days before digging starts. On the York County side, the request goes to South Carolina 811. Then the utilities mark their public lines.
The dig follows the route and depth the trade gives us. In a finished yard we work with a mini excavator. The trench stays open while the trade sets the line and the inspection gets done.
After the inspection we backfill and compact the trench, then grade the top back. Extra dirt leaves on our dump trucks, so hauling the spoils is part of the job. If you want the fill, the spoils can stay on site instead.
Most ground around Charlotte and Union County is Piedmont red clay. Dry clay holds a trench wall well. After a hard rain it turns soft, and the walls can slump. A wet week can push a start date back.
Federal trench-safety rules call for cave-in protection once a trench in soil reaches 5 feet deep. A shallower trench needs it too if the ground shows signs of caving. That protection can be a trench box or walls cut back at a slope. On one of our utility jobs, a steel trench box went in around a new hydrant assembly.
Rock changes a trench too. The Carolina Slate Belt, a band of volcanic rock, runs through Union County. When the machine finds rock partway down a run, the pace changes and sometimes the route does. We tell you what we hit as soon as we hit it.

We set how the equipment gets in, where the material goes and what order the work runs in. Utility locates go in through NC811 before we dig, and any permit stays in the owner or builder's name.
The machines come in and the job gets done in the order we planned. Weather moves earthwork, so we tell you when the schedule shifts.
Spoils, brush and demolition material leave on our dump trucks. We grade the ground back before the equipment comes off the site.
