FGI Updates PVC Geomembrane Specification
The Fabricated Geomembrane Institute (FGI) updated its Material Specification for New PVC Geomembranes, previously referred to as PGI 1104 and FGI 1117. The new specification, FGI 9119, addresses camber or layflat, film gloss, shore hardness, and color deviation within a manufactured lot. The new specification introduces the FGI Circumference Test which measures the roll circumference at the ends and several points along the roll to maintain roll straightness or decrease camber. FGI 9119 also includes requirements for film gloss to reduce blocking or sticking of the geomembrane upon unrolling. A Shore Hardness requirement was also added to improve handling and welding of the geomembrane.
The new specification can be downloaded for free by clicking here.

FGI Offers Short Course in Bogota, Colombia
The Fabricated Geomembrane Institute (FGI) presented a one-day short course at the Sheraton Bogota Hotel in Bogota, Colombia on 12 August 2019. The short course was offered in collaboration with Filmtex, a geomembrane manufacturing company headquartered in Bogota, and the Colombian Chapter of the International Geosynthetics Society (IGS). The all-day short course drew 49 registrants.
The excellent and timely presentations focused on the challenges and environmental concerns associated with mining, tunneling, water, and waste containment technologies and how geomembranes and geosynthetics can be used to mitigate the concerns and risks. The beginning portion of the short course focused on geomembrane fabrication, installation, manufacturing and geosynthetics for civil engineering applications with five (5) presentations. Dr. Timothy D. Stark of the University of Illinois at Urbana-Champaign focused on the new FGI PVC Geomembrane Specification, factory fabrication and field installation, and the Columbus Water Reservoir Project. Juan Cortes and Myriam Acevedo of Filmtex provided insight into the latest advancements in geomembrane manufacturing. Camillo Marulanda of Ingetec Colombia, wrapped up the morning session with an informative presentation on the use of geosynthetics for dam applications.
The second half of the presentations continued the focus on various applications of geosynthetics in containment applications, as well as geomembrane seaming. For example, Marina Villaroel of Alphard (Canada) gave an informative presentation on geosynthetics for mining application. Julio Ferreira of TRI Environmental reviewed the best practices for developing leak location surveys and obtaining a zero leak containment system. Finally, Jorge Herrero Vega of Cesla Mexico, wrapped up the event with a presentation reviewing the the general concepts of geomembrane seaming followed by an interactive welding demonstration that allowed attendees to weld and test geomembranes.
Many attendee questions, comments, and experiences made the course a great success. The topics and speakers from the successful short course are shown below:

FGI Publishes Article on Elvaloy Nomenclature in Geosythetics
June/July 2019
Geosynthetics Magazine
By E. Silva and T. D. Stark
Since the first flexible membrane liner (FML) was used as part of an environmental liner system, the geomembrane industry has always looked for innovative solutions to environmental containment applications. Although there have been many innovations over the last fifty (50) years, one of the most significant is the introduction of ketone ethylene ester (KEE), which is a solid plasticizer. KEE is available under the Elvaloy® trade or product name and is used to plasticize PVC geomembranes as discussed in detail below.
FGI Records Two New Testing Videos
The Fabricated Geomembrane Institute (FGI) at the University of Illinois at Urbana-Champaign has created a library of Geomembrane Test Method Videos that explain various factory and field test methods. Testing videos available to view/download include demonstrations on how to measure the following: thickness, tensile strength, dimensional stability, seam shear and peel strength, and brittleness.
The FGI has recently recorded two new testing videos, as part of the Geomembrane Test Method Library on the FGI website: ASTM D1204 Dimensional Stability and ASTM D1790 Brittleness Temperature of Plastic Sheeting by Impact.
In addition to these two testing videos, the FGI has recorded the following testing videos available to view/download:
ASTM D7408 Seam Peel Strength
ASTM D882 Tensile Properties Geomembranes
ASTM D7408 Seam Shear Strength
ASTM D5994 Thickness Textured Geomembrane
