A tradition of dependability, professionalism and quality unsurpassed in Colorado.
Our estimates are based on our extensive track record—and we deliver.
CASI provides contracting services for asphalt projects using hot mix asphalt from our state-of-the-art plant based in Commerce City, CO. We also recycle asphalt: It’s one of the greenest, most recyclable materials, even more so than wood and aluminum. We deliver the highest quality workmanship on time and on budget—every time.



Asphalt patching is the most effective repair option when a surface has been neglected and water infiltration has undermined the sub-grade material. In this case, removal and replacement is necessary. Asphalt patching can be performed when both air and ground temperatures are above freezing.

CASI asphalt patching improves functionality, repairs damages, and fixes depressions and drainage issues. We deliver the highest quality materials and service in every circumstance, whether it’s a long-term project or an emergency repair that must be fixed now. We’ll complete your repairs on time and on budget—every time. 


With our 30 years of expertise, CASI can determine the solution you need—and deliver it on time and on budget. We’ll work with you to tailor your paving project to your budget, timing, space specifications, and geotechnical requirements. We contract for large and small projects. CASI has delivered high-quality new asphalt paving for subdivisions, retail developments, industrial parks, recreational paths, and municipal streets as well as smaller projects, such as rebuilding existing parking lots. We also provide additional services, including auto-stops, speed bumps, signs, and saw-cutting for your parking lots.
