Concrete Canvas installed for spillway erosion protection at Eagle Gold Mine

24 October 2019

 

Two spillways at the Eagle Gold Mine in Yukon, Canada were lined using Concrete Canvas® (CC) as an erosion control measure.

The spillways were designed to convey any overtopped heap leachate in the case of an extreme 200-year storm event.

The first of the two spillways connects the heap leach pad to an events pond, while the second provides an emergency spillway for the events pond itself.

Poured concrete with an applied coating was considered as an alternative, but was discounted due to logistical requirements and the time that would be required for the installation process.
