Application

Mining Containment

Heap leach pads, tailings ponds and process water storage — containment that resists process chemistry and harsh site conditions.

Open-pit mine

The engineering problem

Mining containment faces process solutions, high UV exposure at altitude, rough subgrades and large lined areas where every field seam is a potential leak path. The liner must be chemically stable, wide enough to minimize seams, and protected against puncture during ore placement.

  • Smooth HDPE geomembrane — impermeable barrier for heap leach pads, tailings and process ponds; excellent chemical resistance; widths to 8 m reduce field seams
  • PP filament geotextile — protection cushion under and over the membrane against puncture from subgrade and ore
  • PET staple geotextile — filtration and separation in solution collection layers
