Under challenging conditions such as those of the coastal desert of San Juan de Marcona, ensuring the waterproofing of tailings dams in mining projects requires high-performance technical solutions and operational efficiency.

For Stage II of the Tailings Dam at the Mina Justa Project, approximately 20 hectares were waterproofed using geomembranes designed to provide a reliable and durable barrier against tailings seepage. These geomembranes are characterized by their high resistance to chemical and physical degradation, allowing them to maintain
long-term integrity in aggressive environments.

Their rapid installation optimized resources and construction schedules, while their flexibility allowed adaptation to site geometry. In this way, the solution not only reinforced the project’s environmental safety, but also added value in terms of sustainability and impact control within one of the most sensitive stages of the mining process.
