Challenges:
- Mechanically Stabilized Earth wall was showing damage from corrosion of galvanized steel bars and meshes from acidic ore leaching into the ground.
- This wall supports the loading platform for the initial ore crusher. Loss of structural integrity would cause production to stop.
ICE Impact:
- Performed lab testing to estimate remaining life of the galvanized steel structures.
- The worst areas were encapsulated with concrete and galvanic anodes were installed. A corrosion monitoring systems to track corrosion activity was installed on the repaired (high risk) areas.
