Secondary containment systems may be required to have a specific thickness for HPDE/RPE liners depending on regulatory requirements and the type of hazardous materials being stored. While there is no universal standard thickness for HPDE/RPE liners in secondary containment systems, common thicknesses range from 20 mil to 60 mil.
Thicker liners provide added durability and protection against punctures, tears, and chemical exposure, making them suitable for containing a wide range of hazardous materials. The specific thickness requirement may vary depending on factors such as the type of chemicals being stored, the size of the containment area, and the environmental conditions. It's important to consult with regulatory agencies and industry standards to determine the appropriate thickness for HPDE/RPE liners.
