FGI Publishes article in Geosynthetics Magazine titled, “Long-term Durability of Geomembrane Material and Seams”

The Fabricated Geomembrane Institute (FGI), 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 of Hibbing in October 1995 with the intention of extracting samples for testing after 2, 4, 5, 10, 20, 25, and 30 years. This update showcases the results from the first 20 years of the program. This ongoing project is investigating the 30-year durability of PVC geomembranes, PVC chemical fusion, and hot-wedge–welded seams. Three 30-mil geomembranes from three different manufacturers were placed at the bottom of a double-lined water treatment settling basin at a Minn. DNR field research site in Hibbing in October 1995. The extreme weather fluctuations and harsh winters with annual freeze/thaw cycles in Hibbing provided an excellent place to really test the durability of the materials.
