Rockwall, Texas · Serving all of DFW
Built on strength.
Built on precision.
Built to last.
Commercial excavation, drainage and sitework. We move the dirt and the water so the rest of your build stays on schedule.
Drainage & Stormwater
HDPE mainlines, French drains, swales, culverts and wing walls engineered to move water off the site and keep it off.
Grading & Site Prep
Laser-controlled cut and fill, building pads and finish grade held to an eighth of an inch across 1,600-foot shots.
Excavation & Trenching
Mini-excavator and backhoe work in tight, active sites where precision matters more than horsepower.
Land Clearing & Demo
Brush, stumps, fence lines and small structures cleared and hauled so the site is ready the day you need it.
Culverts & Concrete Structures
Crossings and headwalls built to spec and dressed so the finished work reads as part of the landscape.
Erosion Control & Restoration
Rock, vegetation and grade working together so the fix holds through the next five-inch rain.
Featured project
Boulder Crest Retreat — Site Drainage & Grading
A flat 67-acre veterans' retreat that put ten acres under water every time it rained. We cut the property a new drainage network, top to bottom, without interrupting a single on-site program.

Why Cornerstone
The subcontractor you don't have to manage
Grade you can verify
Laser control on every shot, held within an eighth of an inch across 1,600 feet. When it rains, the water goes where the plan said it would.
Schedule you can build around
One late day in company history — a single day on a 30-day mandate for an $800K drainage package, delays included.
Finish work nobody asked for
Riprap dressed behind wing walls, limestone set around structures, approaches regraded at no charge. The job looks finished because it is.
A straight answer, fast
Calls and texts returned same day. If something is going sideways on site, you hear it from us first.
