You’re reviewing a geomembrane spec sheet, but it’s filled with confusing acronyms like GRI-GM13 and ASTM D5397. Choosing the wrong material based on a misunderstanding could lead to catastrophic leaks, environmental damage, and costly project overruns.

You’re comparing two suppliers. One claims their product is "high quality," while the other provides a data sheet citing GRI-GM13 and various ASTM test methods. It’s impossible to make a sound decision without a common benchmark for comparison.

GRI-GM13 specifies parameters that measure strength (tensile, puncture), long-term durability (stress crack resistance), and resistance to aging (Oxidative Induction Time – OIT). Each test directly relates to how the geomembrane will perform both during installation and over decades of service.
When I review a test report for a client, I focus on these critical properties. They tell the real story of the material’s quality.

These values aren’t arbitrary. They are the result of decades of research and fieldwork, designed to ensure the material can withstand real-world conditions.

The geomembrane passed all the lab tests and the MQC certificate looks perfect. But now it is on your site, and an installer’s poor welding technique is creating weak seams. A quality product can be ruined by poor installation.

Don’t accept just a summary. Request the full Manufacturing Quality Control (MQC) data for the specific batch and rolls being delivered to your site. Cross-reference the roll numbers and check that every value meets or exceeds the project specification (e.g., GRI-GM13). -
Review the Contractor’s CQA Plan
Before any liner is unrolled, review the installer’s CQA plan. It must detail the testing methods, the frequency of destructive tests, the procedure for all NDT, and how repairs and test failures will be handled and documented. -
