The terms attachments, penetrations and terminations are often considered synonymous, or at least in the same family, when used in the context of geomembranes. This post will focus on attachments and specifically a review of ASTM D6497, one of the main guides for geomembrane mechanical attachments.

What laboratory properties are critical in the selection criteria for geomembranes?
Part 1: Identifying critical geomembrane chemical and environmental resistance properties
“Impermeable” is a common, assumed descriptor of a 21st century geomembrane. We use impermeable barrier materials because they are relied upon to prevent the passing of liquids when used in a variety of engineered projects where a barrier is necessary. Geomembranes are specified for these projects because they are lightweight, easy to install, cost-effective and reliable. To ensure you are selecting the right geomembrane for the application, it’s important to look at testing results for vapor/solvent transmission and puncture resistance, as well as real-world performance.
