With approximately 75 hectares waterproofed, Phase III of Heap Leach Pad 1 at Sociedad Minera Cerro Verde, located in the district of Uchumayo, Arequipa, represents a key advancement in ensuring operational and environmental safety for copper and molybdenum production processes.
During this phase, a waterproofing system combining geomembranes and GCLs was implemented, providing a highly effective hydraulic barrier against liquid and gas seepage, exceeding the performance of low-permeability soils.
The ease of installation—without the need for compaction or transportation of large volumes of clay—significantly reduced execution times and earthmovingrelated costs. In addition, the GCL was installed on steep rocky slopes beneath the geomembrane, further enhancing the waterproofing performance of the project.
