Construction—North America—USA—Hydro & Marine Structures Rock Anchors consisting of 168t of galvanized THREADBAR ® Tendons that were installed in the approach slab of the spillway chute. Furthermore, DSI supplied 75mm Ø, GR 150 THREADBAR ®  Tendons to extend the 30 rock anchors that were installed in phase III as well as the complete stressing equipment and a grease pump. The technical challenge was to develop four different customized anchor geometries to extend just 30 anchors. The rock anchor systems supplied by DSI proved to be superior to those of the competitors. Furthermore, DSI was able to secure this project by taking advantage of its high quality products and excellent customer service.
