About Onyx Concrete

Onyx Concrete started as a small crew in Denver with a simple mission: deliver concrete work that stands the test of time. Twelve years later, we’ve built driveways, patios, and foundations across the Front Range, tackling everything from historic Capitol Hill renovations to Highlands Ranch’s modern builds.

We don’t cut corners. Our team uses high-grade materials and proven techniques to combat Colorado’s freeze-thaw cycles. Every project gets the same attention, whether it’s a stamped patio in Wash Park or a warehouse slab in RiNo.

Denver’s our home too. We’re proud to support local suppliers and hire within the community. When we pour concrete here, we’re building for our neighbors.
