Posted by Felon Wilson on Apr 22, 2021 2:54:02 PM

“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.
