HDPE Geomembrane Mining Liner

HDPE Geomembrane Mining Liner

What It Is

A smooth surface HDPE geomembrane sheet used as the seepage barrier in mining and water containment works. It is produced from virgin HDPE resin (LDPE and LLDPE grades are also made), in thickness from 0.2 mm to 4 mm, roll width 1 m to 8 m and roll length from 50 m to 420 m, in black, white, green or blue.

What It Does

• Seepage control: the continuous polymer sheet stops liquid from entering the ground, so leachate and process water stay inside the cell.
• Chemical and corrosion resistance: the membrane holds up against the acidic and saline waters met in heap leach pads and tailings storage.
• UV resistance and long service life: carbon black in the sheet protects it in open exposure, and the liner stays flexible through seasonal temperature swings.
• Weldable: the panels are joined by wedge and hot air welding on site, so a continuous layer is formed over the prepared subgrade.

The material is eco friendly and does not rot; the smooth face shown here is the general purpose grade, and a textured face is available for steep slopes.

Where It Is Used

Tailings ponds and heap leach pads, mining water and process reservoirs, evaporation ponds, dam and canal lining, potable and irrigation reservoirs, fish and shrimp pond lining, landfill base and cover systems, and concrete tank and bund lining.
