The Fabricated Geomembrane Institute (FGI) held its biennial membership meeting on 24 February 2021 during the Geosynthetics 2021 Conference. The meeting was attended by 26 people and held in conjunction with the Industrial Fabrics Association International organized conference. During the membership meeting, the newly elected FGI Officers and Board of Directors were introduced for their two (2) year term.
Before introducing the new Officers and Directors, Timothy D. Stark, FGI Technical Director and Professor of Civil Engineering at the University of Illinois at Urbana-Champaign, acknowledged the service of the outgoing Officers and Board Members: Greg Scales (Titan Environmental), Bill Shehane (Seaman Corporation), and Ed Silva (E Squared). Tim also acknowledged the recent retirement of John Heap from Colorado Lining International. John served as President of the PVC Geomembrane Institute(PGI) for four (4) years and was instrumental in expanding the PGI to the Fabricated Geomembrane Institute.

· Created Women in Geosynthetics Program – hosting two successful Round Table Discussions and quarterly virtual meetings
The final portion of the FGI Biennial Membership Meeting was dedicated to a lively discussion on the future direction and goals of the FGI by its members. The FGI has five membership classifications: manufacturers, fabricators and Installers, Installer Only, Associate, and Government/Regulatory Agency. The FGI’s membership spans four continents: North America, South America, Australia, and Europe.
The FGI is dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer. The FGI is a consortium of manufacturers, fabricators/installers, designers, regulators, and material suppliers of fabricated geomembranes.

The Fabricated Geomembrane Institute at the University of Illinois has created a group titled, “Women in Geosynthetics (WIG)” in order to promote the advancement of women in the geosynthetics industry through education, networking and mentoring opportunities. Audience participation is the focus of this highly interactive discussion
The discussion will include, but is not limited to the following points of interest:
– How can we recruit MORE women into the Geosynthetic Industry?
– How can we create more opportunities in the industry for women?
– What types of educational opportunities are out there to educate women throughout the industry?
– Mentorship Opportunities

The Fabricated Geomembrane Institute (FGI) presented a short course in Charlotte, North Carolina on 6 November 2019 at the Center City Building to a sold out crowd. The short course was organized by the FGI and was offered in collaboration with the University of North Carolina at Charlotte (UNCC).
The excellent and timely presentations focused on the regulations, placement, and management of CCRs, with an emphasis on using geosynthetics. The morning portion of the short course focused on regulatory issues, containment applications, CCR static properties,and seismic behavior of CCRs. For example, a presentation by JR Register of Consumers Energy, focused on the current and emerging CCR regulatory issues, while Evan Andrews of Duke Energy provided insight into using geosynthetics to manage, cover, and contain CCRs. Gary Zych of American Electric Power (AEP)reviewed containment applications for CCRs for AEP facilities. Vincent Ogunro of UNCC followed with an informative presentation on the static material properties and treatment of CCRs. Lastly, Professor Bill Wolfe of The Ohio State University described the seismic behaviors of CCRs and conducting liquefaction analyses for CCRs to wrap up the morning portion.
The afternoon presentations focused on the practical applications of geosynthetics for CCR management, closure, and containment. For example, Allen Bullock of Leister and Matthew Roy of DemTech provided a demonstration of geomembrane seaming, patching, and testing. Timothy D. Stark of the University of Illinois at Urbana-Champaign reviewed the importance of geomembrane wrinkles in leakage rates and leak location surveys. Ken Daly of Wood PLC gave an informative presentation on local practices for managing CCRs. Sam Allen of TRI Environmental provided insight on leak location surveys. Finally, Joe Troxell of S&ME described the largest fabricated geomembrane project in the world, i.e.,Columbus, Ohio Upground Water Reservoir.
Many attendee questions, comments, and experiences made the course a greatsuccess. The topics andspeakers from the successful shortcourseare shown below:

This calculator estimates the leakage through geomembranes and composite liners with and without geomembrane defects/holes. The calculator illustrates the importance of intimate contact between the geomembrane and compacted subgrade or soil liner via different levels of contact. The effect of wrinkles on leakage rates is also quantified using a database of wrinkle dimensions for a number of common geomembranes, which shows the presence of wrinkles can significantly increase leakage rates.

Construction of this 67 meter high reinforced soil slope (RSS) was completed in December 2006. After seven years in-service, a tension crack was observed at the top of the slope. In March 2015 this RSS structure catastrophically collapsed. This RSS structure collapsed in a compound failure mode; as the failure plane passed beneath, partially behind, and partially through the reinforced soil mass. The RSS collapse occurred after 8.3 years in-service as the shear strength along the shale-claystone foundation interface decreased and approached the fully softened strength. This webinar will cover the forensic investigation performed, the causes of the failure and lessons learned.
