Apr 20, 2020 · Mining companies stretch the capabilities of geomembranes to their limits and sometimes to the point of failure. For example, leach pads are heaps of rocks/ore up to 120–180 m high piled on a geomembrane pad. In addition, there is traffic on the liner leach pad in the form of truck hauls or dozer pushes.

High Density Polyethylene (HDPE) is a thermoplastic polymer obtained by the polymerisation of ethylene. As one of the most versatile plastic materials, HDPE plastic is used in a wide variety of appliions, especially in hazardous waste containment and water storage. Known for its excellent tensile strength and high strength to density ratio ...
