Summary: Landfill base >=1.5 mm, hazardous waste >=2.0 mm, biogas lagoon 1.0-1.5 mm, reservoir 0.75-1.5 mm, aquaculture 0.3-0.75 mm. Thickness follows risk class, water head and base condition - and the design document.
Thickness is the first question in every inquiry. The answer is risk-based, not preference-based.

Beyond thickness
OIT and environmental stress-cracking resistance matter as much as thickness; a thin virgin membrane outlives a thick recycled one. Follow the design document for regulated projects.
