For almost 50 years the ground support group of the Thiessen Team has been servicing underground mining customers and civil contractors with a complete line of rock support and soil nailing products.

DSI-Thiessen supplies products, and is committed to our customers by having on staff a team of engineers and rock mechanics experts to provide hands-on training in the application of our products. We are located in major mining centres across North America to better service our customers.

Now Thiessen has merged its ground support services with Dywidag Systems (DSI) in North America, to create a new entity:
DSI-Thiessen Mining Products.
