Nashville's Excavation Experts

Onyx handled our East Nashville renovation's tricky foundation work perfectly. They navigated the existing 1930s brick pier foundation while digging new footings for our addition. When they hit an unexpected limestone shelf, their crew had the right equipment to break through without damaging our neighbor's property. The site was cleaner when they left than before they started!

Our Brentwood property needed serious grading and a natural-looking pond. Onyx's team created a stunning water feature that handles runoff from our sloping lot. They preserved several mature trees right at the water's edge - I don't know how they got equipment in there without damage. Two years later, the banks haven't eroded an inch during heavy rains.

Running new sewer lines through Murfreesboro's rocky soil was a nightmare until we hired Onyx. Their rock saw made quick work of the limestone that stopped other contractors. They coordinated perfectly with the city inspectors and had our site re-graded and seeded before the next rain. Worth every penny for the lack of headaches.

Preparing our Franklin hillside lot would have been impossible without Onyx's expertise. They terraced the slope beautifully, creating a stable building pad while preserving the natural look we wanted. Their erosion control measures held up through two major storms during construction. The architect said it was the best-prepared site he'd seen in Williamson County.

Clearing our Hendersonville property was more complex than expected with protected wetlands. Onyx worked with TDEC to mark all boundaries and created a beautiful transition zone to the lake. Their forestry mulcher left the ground ready for seeding - we saved thousands not having to haul away debris. The deer were back browsing within a week!

Building on The Gulch's rocky terrain had our architect worried, but Onyx's crew made it look easy. They laser-leveled the foundation pad perfectly despite the site's slope and underground ledges. When they uncovered an old cistern, they preserved it intact for our landscape feature. These guys treat your property like it's their own.
