Two Examples of How to Overcome Differential Water Levels in Geomembrane Applications

Posted by Felon Wilson on Oct 18, 2021 8:17:20 AM

Many in the geosynthetic industry believe a geomembrane is only a fluid barrier and, in theory, needs very little strength. Any strength requirements are met by ancillary means, such as additional geosynthetic members or other load-bearing members. But few installations can be assured—with complete certainty—that they will not require some load bearing from the geomembrane itself.

Five Considerations for Selecting a Geomembrane for Secondary Containment

Posted by Felon Wilson on Sep 13, 2021 1:05:16 PM

Federal regulations requiring safeguards against spills of bulk liquid storage (most commonly petroleum) have been in effect since the Clean Water Act was passed in 1972. Geomembranes are used to line bermed areas that have been created to provide sufficient storage volume for spill containment and associated rainfall. There are important properties that determine which geomembranes are most suited to these critical applications:

Top 5 Techniques for Dealing With Thermally Induced Wrinkles in Geomembranes

Posted by Felon Wilson on Aug 23, 2021 8:31:31 AM

The discussion in the geomembrane industry regarding how to overcome the effects of thermally induced wrinkling has become more active recently. Some geomembranes exhibit high levels of Thermal Expansion Contraction (CTE). As far back as 2007, recommendations were that geomembranes must be flat when backfilled (Koerner, Daniel, ASCE 2007), a recommendation that most agree is difficult to meet with many geomembranes.
