The industry standard HDPE geomembrane thickness for tank farm containment is typically between 1.5mm (60 mil) and 2.0mm (80 mil). However, the exact thickness depends entirely on subgrade conditions, the stored liquid's chemical profile, construction risks, and the project's required lifespan.

Heavy chemicals can slowly swell or degrade thinner plastics. In chemical containment liners, stepping up to a 2.0mm thickness provides a larger sacrificial mass. The thicker the geomembrane, the longer it takes for aggressive chemical diffusion to compromise the barrier's integrity. Fuel versus harsh chemicals changes the thickness calculation entirely.
