Part 2: Top ways to overcome difficulties interpreting geomembrane chemical resistance data
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:
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.
