Welcome to Cu Onsite Services. We are a full service excavating, pavement, and concrete company based in Severance, Colorado. We specialize in municipality and commercial sidewalks, curbs, and gutters. We are the only Colorado concrete company to also offer site prep and asphalt work. We’re fully equipped to prepare the site and pave parking lots, driveways, and roads. We also sweep and stripe when we’re finished. Our main focus is establishing proper drainage to protect your investment in your construction project and minimize your liability long after the project is completed. We also offer general contracting services and what we call “value engineering,” where we coordinate trades and manage job logistics to keep projects ahead of schedule and on budget.
