Dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer.

Factory fabrication reduces field welding, reduces installation time and costs, allows modular construction and provides consistent seam and liner quality.

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:

The workshop will train field installers on seaming, patching, attachments, and testing of pre-fabricated/flexible geomembranes, such as Woven Coated Polyethylene (PE), Polypropylene (PP), PVC, and Reinforced Products (PP/PE/EIA).  The testing will include Air Channel, Air Lance, Vacuum Box, and Tensiometer Testing.

The cost of the workshop is $200 per person.  However, FGI Members can send their installers to the workshop for FREE.  FGI installer membership is only $1,000 so if you are sending five (5) or more, please consider joining the FGI.  A continental breakfast, lunch, and morning/afternoon snacks will be provided.

Space is limited.  Everyone must register by 12/20/19:

In Memoriam of Robert and Paula Koerner

The Fabricated Geomembrane Institute and its members would like to express our condolences on the passing of Dr. Robert M. Koerner and his wife Paula W. Koerner. Together, Bob and Paula founded the Geosynthetic Institute (GSI) in 1986 and maintained it at the forefront of the industry.  In addition, Bob was the “Father of Geosynthetics” and brought geosynthetics into main stream civil engineering.  Bob´s academic contributions to the industry include over 750 papers on geosynthetics and the pioneering textbook, “Designing with Geosynthetics” which is now in its sixth edition. The FGI is grateful for all of Bob’s and Paula’s contributions to the geosynthetics industry and encourage our members and others to visit the Koerner Family Foundation website at
