A History of Problem Solving

When Crux first began installing micropiles in 2002, the company was already known for providing difficult-access geotechnical exploration services throughout the western United States for tunnel, dam, highway and slope stabilization projects, including the Hoover Dam Bypass.  Crux initially utilized micropiles for structure foundation support and slope stabilization before adapting the technology as a foundation alternative in the electrical transmission market. Micropiles provide the ability to install a high capacity deep foundation system in remote or environmentally sensitive locations, explained Tunison, Crux’s Vice President of Operations.

“Micropiles are replacement piles constructed using high-strength grout and steel, and can be installed using lightweight equipment,” he explained.

In 2004, Crux began construction on the 57-mile-long Swan Lake-Lake Tyee Intertie between two hydroelectric projects in Southeast Alaska.  This was the first project of its magnitude to use helicopter-supported micropile foundations exclusively for its whole alignment, relying on Crux’s customized drills, skilled helicopter support, and specially trained drillers.
