Columbia Quarry’s Commitment to Quality, Safety, and Sustainability
Columbia Quarry Co. is proud to lead with quality across every part of our operation, from blasting and crushing to hauling and customer service. We hold ourselves to the highest safety, environmental, and compliance standards because we believe better material starts with better practices.

Graded and Verified Rock Material
Columbia Quarry Co. offers A, B, C, and D grade rock to support everything from heavy infrastructure builds to fine leveling. These materials are produced using high-performance crushing equipment and monitored to ensure they pass inspection and meet agency specs. That’s quality you can count on. Certain rock products of CQC meet stringent material standards set by the Illinois Department of Transportation (IDOT) and Missouri Department of Transportation (MoDOT).
Proud Members of the Southern Illinois Builders Association
