Leaders in top quality drilling and blasting operations, Castonguay Blasting was founded in 1971. Since then, we have expanded our business to serve all regions of eastern Canada, and even abroad.

Place our expertise
behind your projects

Leveraging a wealth of experience in its field, Castonguay Blasting has the expertise necessary to undertake any size drilling or blasting project in the mining, quarrying and civil engineering sectors. Using tried and true working methods, our team moves several millions of tons of rock every year!

An equipment fleet
to take over
any project

Thanks to our diversified state of the art equipment fleet and our vast expertise, we are able to take on any type of project you may have. Moreover, since the best drilling equipment on the market was not quite up to our standards, we have also developed our own down-the-hole drills whose performance is absolutely outstanding.
