Chemical Resistant and Abrasion Resistant Geomembrane Liner with Low Permeability for Heap Leach Pads

The LeachMax™ Geomembrane Liner is a precision-engineered containment solution that maximizes metal recovery efficiency by creating an impervious collection system for valuable leachates.

• Superior chemical resistance to aggressive reagents like cyanide and sulfuric acid
• Enhanced surface abrasion resistance for durability under ore placement
• Optimized for low permeability to minimize precious solution loss
• Designed for rapid deployment and reliable field seaming

Primary liner for dynamic and permanent heap leach pads, solution collection channels, and pregnant solution ponds.

The optimal choice for gold, silver, and copper heap leach operations focused on maximizing recovery rates and operational profitability.

The Chem-Barrier™ Geomembrane is a chemical-resistant workhorse, built to withstand the most demanding heap leach environments while ensuring operational continuity and environmental protection.

• Formulated for targeted inertness against specific leaching chemicals
• Exceptional multi-axial strain capacity to accommodate subgrade settlement
• High puncture resistance for direct contact with coarse ore
• Maintains flexibility and strength in extreme ambient temperatures

Lining for primary and secondary leach pads, emergency containment ponds, and raffinate lines.

Essential for operations using highly aggressive lixiviants or in remote locations, where liner integrity is paramount to preventing costly downtime and environmental incidents.
