Ledcor Group CC8 TM and CC13 TM used to line a carrier drain channel directing contaminated water from a mine to a setlling pond

Completed lined channel and culvert In February 2012, Concrete Canvas ® GCCM* (CC) was used to line a carrier drain channel on the Willow Creek mine site in British Columbia, Canada. Willow Creek is a large open pit mine located 45 kilometres west of the town of Chetwynd, in northeast British Columbia. The mine is a truck and shovel operation and is capable of producing both hard coking coal and low-volatile PCI coal for steelmaking. The carrier drain channel was 10.5–12m wide, between 3–5m deep and approximately 650m long. The purpose of the carrier channel was to direct mining industrial waste fromWillow Creek mine to a nearby settling pond. The overall size, performance requirements of this particular application, as well as the cost potential meant that Ledcor were reluctant to use Shotcrete. The client also specified that the lined channel had to be as water tight as possible, could handle freeze/thaw conditions, due to the cold winter temperatures in the area, and should be easy to repair. Following the recent success of a 52,000m 2 CC installation in the Alta Montaña III region of Chile, contractors Ledcor Group specified CC as a protective liner for the channel.
