We are a family-owned and operated full-service rock drilling and blasting contractor that has been performing precision drilling and blasting in highly-controlled environments since our inception in 1988. We currently operate throughout the Western United States. 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 McCallum Rock Drilling, McCallum Powder was created in 2016 to assist in the manufacturing, storage, and transportation of explosive products for all McCallum Rock Drilling blasting operations.
