All activities in the APAC region are coordinated from Australia, where DSI has been the absolute market leader for many years.

DSI also supplies high quality Tunneling products and systems throughout the Asia/Pacific region. The product range includes a wide variety of anchors, rock and ground support systems as well as field-proven AT systems such as the AT Casing System for the economic installation of tube spiles.
