Professional Rock Drilling and Blasting Since 1988.

McCallum Rock Drilling (MRD) is a family-owned and operated full-service rock drilling and blasting contractor. We have been performing precision drilling and blasting in highly-controlled environments since our inception in 1988.

We currently operate throughout the Western United States including Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, Oregon, Texas, Utah, Washington and Wyoming and beyond. We perform all applications of drilling and blasting including large scale commercial quarries, heavy construction, road and highway construction, residential and commercial development, and utility and trenchline work.

In addition to MRD, McCallum Powder was created in 2016 to assist in the manufacturing, storage, and transportation of explosive products for all MRD blasting operations.

We also have a robust safety division and offer a variety of safety services for the mining, construction, and timber industries. These include both in-person and virtual MSHA Part 46 and Part 48 training, safety audits, and accident investigations.

All day, every day, rock drilling and blasting is what we do.
