Every frame is our own work.
Six disciplines, six archives — the real photographs from the field. No stock, no stand-ins, no one else's machines.
Asphalt and gravel paving for Front Range driveways and small commercial lots — graded, compacted, and sealed against Colorado freeze-thaw.
Justin Nau is on a mission to shape Colorado.
We help you build, protect, and improve your mountain property — new construction, additions, wildfire prep, and the seasonal work that keeps it all standing.
What started as one operator and one machine has grown into a full team of specialists — the Front Range's go-to for excavation, hardscaping, fire mitigation, and site work across multiple territories. Justin still runs every project, but the crew behind him is what makes the scale possible.
Every photograph on this site is work carried out by our own hands. No stock. No stand-ins.
