Mining & heap leach
Process solution pads and ponds needing chemical resistance with documented compressive strength under ore loads.
Solmax Geomembrane Systems for High-Stress Containment
Polymer-engineered HDPE liners and geosynthetic assemblies that protect groundwater, process solutions, and critical infrastructure where UV stability, puncture resistance, and dimensional stability decide project risk.
Engineered performance
Containment physics that holds under load, heat, and chemistry
Solmax designs geomembranes around measurable field stresses—not brochure adjectives—so specification teams can defend liner selection against chemical exposure, slope stability, and long service life expectancy targets.
-
01
UV stability for exposed slopes
Stabilizer packages maintain tensile retention on exposed faces where temporary cover schedules slip and solar load accelerates aging.
-
02
Puncture and impact resistance
Formulations balance flexibility with impact resistance so subgrade angularities and equipment traffic do not open leakage pathways.
-
03
Dimensional stability under thermal swing
Controlled shrinkage behavior reduces seam stress during day-night cycles on large basins and landfill cells.
-
04
Moisture vapor transmission control
Low permeability pathways keep process solutions and leachate where hydraulic models expect them to stay.
-
05
Documented compressive strength paths
Interface shear and cushioning guidance help designers pair liners with drainage geocomposites under high normal stress.

Where liners earn their keep
Containment environments that demand Solmax geomembranes
From heap leach pads to potable water reservoirs, Solmax materials are specified when leakage, UV aging, or slope interface failure would halt operations.
Compliance evidence
Certifications that travel with the specification package
Quality and environmental systems accompany every Solmax manufacturing lot so owner engineers can attach third-party proofs without rewriting procurement language.
ISO 9001:2015
Quality management across extrusion, testing, and lot release documentation.
ISO 14001:2015
Environmental management for resin handling and plant energy intensity tracking.
GRI alignment
Reporting frameworks that support owner ESG questionnaires on recycled content percentage and embodied carbon.
NSF/ANSI 61
Potable-water contact pathway for selected geomembrane constructions used in reservoirs.
