Duratec was engaged by Barrick Gold’s Kanowna Belle mine to repair concrete and coatings to maintain Cyanide Code compliance in the cyanide storage bund.

Details

The project involved the manual breakout of delaminated concrete and the replacement of corroded reinforcing bars. The concrete was reinstated along with a 12 metre new concrete wall.

The entire bund was then protected with Polyeuro 5502 – a high performance, chemical resistant, instant curing polyurea applied by specialised plural component airless spray equipment. The coating was also used seal the tank ringbeam in combination with geotextile providing the bund with a complete monolithic seal satisfying cyanide code requirements.

Highlights

  • Workers were required to use full acid suits during the entire project.
  • Cyanide deliveries that affected continuity increased the degree of difficulty of the project.
  • The project was completed incident free.
