For the most part, all geomembranes have a similar broad function: A fluid barrier. When comparing, the confusion lies in the fact that they are manufactured by different methods and constructed differently, which result in varying properties to accomplish the broad fluid barrier function. Plus, the definition of “fluid barrier” is subjective depending on a host of site, application, fluid composition and regulatory factors. Key geomembrane properties are required to support the overall function.

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.
As Engineers, we use the term “failure” in a number of ways but know that it implies something did not perform as expected. Was it the fault of the “failed” thing or action, or was it a failure in how it was expected to perform, under those conditions? Regardless, we all know that failure brings negative connotations in many ways, and none are desirable.
Our team was recently invited to speak with Shannon Oelkers from Integrity Environmental on their podcast Tank Talk regarding XR® Geomembrane liners and how they perform in extreme environments.
What laboratory properties are critical in the selection criteria for geomembranes?
