On the evening of February 3, 2023, a train derailed in East Palestine, Ohio. The tanker cars, carrying several types of chemicals, ruptured, and caught fire.
The aftermath unfolded in the news for days, weeks, and months. The event impacted the population of the small community most directly, but also created an environmental investigation for Ohio and the surrounding states of Pennsylvania and West Virginia.

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.
Geomembrane warranties are typically provided by the manufacturer. Standard warranties are usually included at no additional cost and vary among manufacturers and products, in coverage, duration and other factors. It can be confusing trying to understand what a warranty really says. What needs to be considered when evaluating a geomembrane warranty?
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.
