Client:Emil Anderson Construction
Location: Fraser Canyon, BC
A small rock slide occurred at the North end of the Hell’s Gate Atrium Parking lot, immediately adjacent to Highway 1 through the Fraser Canyon. The rock slide compromised one of the south-bound lanes of traffic. Emil Anderson Contracting hired TerraCana Foundation Solutions to install a micropile & tieback foundation to support an MSE wall.
Site access required a light weight drill capable of case hole drilling both vertical and tieback anchors at very complex angles. Drilling conditions were highly variable including overburden, blast rock and bedrock.
TerraCana used a modified Air-Track drill equipped with a rotary top drive motor and external hydraulic power pack to complete the drilling work. A combination of open hole and case hole drilling was utilized depending on each hole’s conditions. Once drilling was complete, TerraCana completed the concrete works to support the MSE wall.
