LLDPE Geomembranes

Solution ponds and heap leach pads used in the mining process require the most durable containment lining systems available. GSE UltraFlex is an LLDPE (linear low-density polyethylene) geomembrane developed to meet the specific needs of the mining industry.


  • Material is manufactured in rolls 22.5 feet wide for fewer field seams, faster installation and less opportunity for leakage.
  • For situations requiring installation on steep slopes, GSE offers a unique method for texturing the geomembrane for improved friction to help adhesion to the soil.
  • With hundreds of millions of square feet installed worldwide, GSE geomembranes have been extensively field tested and proven.
