☀️Sunshine, steel, & serious horsepower 💪🏼

We couldn’t ask for better weather to be out moving dirt! Today, our Komatsu D71 Dozer and Versatile 500 with K-TEC 1228 scraper are soaking up the sun and getting the job done.
Whether it’s site prep, grading, or full-scale excavation — we’ve got the iron and the crew to make it happen.
📍 Just another day doing what we love here at Cornerstone Excavating!
Give us a wave if you see us out and about — or just leave a “🚜” below if you wish you were in the cab today.

🚧It’s Friday - may your lines be marked, your dig go smooth, and your buckets stay dry 😅😉
