• HDPE Geomembrane 1.5mm Textured: The Ultimate Solution for Acidic Tailings Pond Containment

  Jan 15, 2026

  Specific Application Scenario A copper mine in the Atacama Desert region of Chile produces tailings slurry with a consistently low pH of 2-4 (highly acidic) and contains soluble metal ions. The project required the construction of a 50-hectare tailings storage facility with a 30-year design life. The core challenge was to find an absolutely reliable primary containment liner that could withstand the combined stresses of intense UV radiation (at 3000m altitude), significant daily temperature fluctuations (-5°C to 30°C), and chemical corrosion, to prevent toxic leachate from contaminating the underlying aquifer.   Solution and Long-Term Performance Data After rigorous chemical compatibility testing, the project selected a 1.5mm thick textured HDPE geomembrane as the primar...
