FGI Expands Geomembrane Durability Study
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 installed primary liner system. The Minnesota Department of Natural Resources (MN DNR) became a partner, and the study was started in October 1995. The study selected a MN DNR mine settling basin in the town of Hibbing, Minn., for the long-term study.
The main objective of this ongoing project is to investigate the 30-year durability of PVC geomembranes and PVC chemical fusion and hot wedge-welded seams. At the beginning of the study, samples of three 30-mil (0.8-mm) geomembranes from three different manufacturers were placed along the bottom of a double-lined mine settling basin at the reclamation site. The weather extremes and the harsh winters with many freeze/thaw cycles provided an excellent venue to test the durability of these geomembranes. The settling basin contains mine drainage that has been neutralized with magnesium hydroxide from mine waste rock piles. Three strips of PVC geomembrane–originally 6-feet (1.8 m) wide and 50-feet (15.2 m) long—were installed in 1995. After exhumation and sampling events two, four, five, ten and twenty years after placement of the samples, the test strips are shorter but still buried in a 6- to 12-inch (15–30-cm) thick sand cover at the bottom of the basin. Each test strip contains a single seam that runs the entire length at the center line of the test strip. Two of the strips have chemical seams, and the other has a 1.5-inch (3.8-cm) wide single wedge welded seam.
Geomembrane samples were previously collected and tested after two, four, five, ten and twenty years in the basin, and the materials still meet the original specifications. Following the retrieval of the 20-year samples, it was determined that there was sufficient space available in the basin to install additional materials. After discussions with the MN DNR, it was decided to install eight new materials with dimensions of 6-feet (1.8-m) wide and 25-feet (7.6-m) long. These samples also contained a seam at the centerline, but all seams were created using a thermal welder. Therefore, on Sept. 21, 2017, the FGI and the MN DNR installed eight additional geomembrane material samples on the bottom of the mine settling. The eight new geomembranes installed are:
- 36-mil reinforced polypropylene, provided by Cooley Group (CG)
- 30-mil single film laminated woven coated polyethylene, provided by Owens Corning Inc. (OC)
- 30-mil single scrim coated woven coated polyethylene, provided by Intertape Polymer Group (IPG)
- 40-mil unreinforced LLDPE, provided by Raven Industries (RI)
- 30-mil XTRM Ply ethylene interpolymer alloy (EIA) formulation geomembrane, provided by Engineered Polymer Technologies (EPT)
- 30-mil XR-5 ethylene interpolymer alloy (EIA) formulation geomembrane, provided by Seaman Corporation (SC)
- 30-mil PVC geomembrane, provided by Plastatech Inc. (PI)
- 30-mil smooth HDPE geomembrane, provided by GSE Environmental (GE)
The FGI will perform exhumation, sampling and testing of the newly installed materials after five, ten, fifteen, twenty and twenty-five years. In addition, large archive samples of each geomembrane were retained before installation for archival purposes. These archival samples were shipped to the University of Illinois at Urbana–Champaign for storage.

FGI OFFERS FIRST EVER LIVE STREAMING SHORT COURSE
The Fabricated Geomembrane Institute (FGI) presented a live-streamed short course at the University of Illinois at Urbana-Champaign (UIUC) on 3 August, 2018. The short course was organized by the FGI and was streamed on-line by the Geosynthetic Materials Association (GMA). The short course was offered as a set of six continuous webinars, with a one-hour lunch break separating the three morning sessions and the three afternoon sessions. The all-day short course drew 210 registrants, with over 100 attendees streaming at any one time.
The excellent and timely presentations focused on the challenges and environmental concerns with containment and engineering technologies and how geosynthetics and geomembranes can be used to mitigate the concerns and risks. Andy Durham of Owens Corning served as the emcee for the short course; introducing each speaker, as well as moderating the live question and answer section at the end of each presentation. The beginning portion of the short course focused on geomembrane life and performance. Dr. Kerry Rowe, of Queens University focused on service life of geomembranes, while GlenToepfer, of CQA Solutions provided insight into the latest advancements in geomembrane testing and certified quality assurance (CQA) procedures. Finally, Dr.Kerry Rowe concluded the morning sessions with an informative presentation on the effects of wrinkles on geomembrane performance.
The second half of the presentations focused on various applications of geosynthetics in civil engineering applications. For example, Sam Allen, of TRI Environmental reviewed the best practices for zero leak containment. Gary Zych, of American Electric Power in Columbus, Ohio gave an informative presentation on effective disposal techniques for Coal Combustion Residuals using PVC geomembranes. Finally, Dr. Timothy Stark, of the UIUC wrapped up the live-streamed event with a presentation detailing elevated temperatures in containment applications.
Many attendee questions, comments, and experiences made the course a great success. The topics and speakers from the successful short course are shown below:

· Video library of ASTM test methods – The FGI is in the process of developing a library of high quality videos for our website and YouTube channel that explain and demonstrate all of the different ASTM test methods used for testing flexible geomembranes.
· Short courses – The FGI has two additional short courses scheduled for 2018 that will address Geosynthetics in Civil Engineering Applications: Friday, August 3, 2018 at the University of Illinois at Urbana-Champaign (will also be recorded and live-streamed) and Wednesday, October 24, 2018 at Saginaw Valley State University (in collaboration with Consumers Energy and Plastatech).
· Summer Internship program – In 2018, the FGI plans to continue to expand its internship program by developing new partnerships with other Universities (e.g. Colorado State University and The Ohio State University) to provide more geographically friendly interns to its members.
· Clay v. Geomembrane Costs Paper – Conference paper is being written to highlight the benefits and cost savings of using geomembranes over compacted clay soil for containment applications.
· RPP Project Case Study – The FGI is working on a case study of a premature failure of an RPP pond liner system, along with a new installation of an RPE system including mechanical attachment, venting system, ballast system to prevent uplift if ground water becomes an issue, anchor trench, underlayment, pipe details and panel fabrication.
· Installation Details – The FGI is creating a library of installation details for engineers and clients to download from the FGI website in both JPEG and DWG formats.
