Nothing is indestructible, and that includes a geomembrane. While they are designed as a barrier against liquid, there are a variety of mechanical activities that will prevent a geomembrane from functioning as intended. Plus, these activities will also adversely affect the longevity of the geomembrane as well.
One way to classify secondary containment of stored industrial liquids is either permanent or portable. Both routinely use the same type of geomembrane as the primary containment layer. In this blog, we will compare the two applications and look at the principal ways geomembrane use is the same and how it differs in permanent vs. portable secondary containment.
Some see geomembranes as static fluid barriers, which means they are not subject to movement nor are they expected to carry any load. This includes load induced by the geomembrane’s weight itself and any weight imparted onto the geomembrane by redundant protective layers. However, there are common situations where movement of the geomembrane is inherent to some degree in the application.
In this post, we will take a look at these applications.
When the proper geomembrane installation is used and operated correctly on an engineered project, it can be a cost-effective way to create a sound fluid barrier. While any construction project will have variables that make it unique and each site/application will have its own set of complexities, geomembrane solutions can be readily optimized for the need.
