Applications

The definitive solution in mining and more

Efficiency and reliability in evaporation processes

With millions of square meters of geomembranes installed in mines, lagoons and industrial environments, Coverfilm is positioned as a reliable option. Our geomembranes are crucial in evaporation ponds, a key component in the concentration of saline solutions such as lithium carbonate, lithium hydroxide and various nitrates and sulfates. Designed for maximum efficiency, our geomembranes optimize the use of heat and wind, guaranteeing a more effective and profitable evaporation process.

Various applications

Leaching Piles: Our geomembranes are essential to optimize the leaching process.
Tailings Dams: Keep your tailings safe and contained.
Sealing and Closure of Mines: Essential for the environmental rehabilitation process.
Oil Industry: Confirmed versatility in applications such as rain covers (Rain Cover).

Environmental Rehabilitation

We are aware of the challenges and risks associated with the industry. Our geomembranes are essential in sealing and closing mines, helping to rehabilitate the environment.

Superior performance in Lithium Mining

Our HDPE geomembranes are especially efficient in the difficult climatic conditions of the Lithium Triangle. Manufactured with 100% virgin resins of the highest quality and additives that increase their durability, our geomembranes offer a differential value.

Installation Efficiency

Thanks to the wide-width design (up to 8 meters) of our geomembranes, we achieve faster installation, reducing personnel exposure to hazardous working conditions and minimizing costs. This design also ensures a better final finish by requiring less welding, which reduces the probability of failure. Coverfilm geomembranes are ideal for lithium brine extraction. Our HDPE geomembranes maintain the integrity of the evaporation pools, allowing optimal saturation and crystallization of salts.
