Minnesota geomembrane durability study expanded
January 31st, 2019
More than twenty years ago, the founders of the PVC Geomembrane Institute (PGI) and the succeeding entity Fabricated Geomembrane Institute (FGI) set out to evaluate the long-term durability of geomembranes in actual field use. They wanted to exhume numerous samples of exposed geomembranes for testing on a periodic basis without ruining the integrity of the […]

Protecting geomembranes from animal damage
June 1st, 2017
Resisting animal and insect attacks on geomembranes is an interesting problem. Geomembrane installers and manufacturers have had numerous geomembranes damaged by bears, deer, coyotes, birds, beavers, and ground squirrels (Figures 1 and 2). In most cases, the damage is incidental to something else the animal is seeking. Deer damage the liner with their hooves trying […]
Long-term durability of geomembrane material and seams
April 1st, 2017
Introduction The Fabricated Geomembrane Institute (FGI), formerly the PVC Geomembrane Institute, in collaboration with the Minnesota Department of Natural Resources (Minn. DNR), has been conducting a study assessing the long-term durability of PVC geomembranes. Samples of three different 30-mil PVC geomembranes were placed at the bottom of a settling basin near the northern Minnesota town […]
