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:

The Fabricated Geomembrane Institute (FGI) is pleased to welcome its newest Associate Member, GeoTesting Express (GTX). GTX provides state-of-the-art laboratory testing facilities to measure the mechanical and physical properties of soil, rock, geosynthetics, aggregate, concreate, and other geo-materials. GTX also prides itself for its best practices and advanced testing equipment to provide fast, accurate results. GTX offers a combination of field expertise and knowledge, backed by supervising engineers and full-service, quick responding testing laboratories to provide value to project teams. GTX’s testing laboratory is headquartered in Acton, Massachusetts, with an additional lab located in Atlanta, Georgia and their FGI liaison is Anna Kotas, Geotechnical Engineer, who can be reached at firstname.lastname@example.org. Please help us welcome GeoTesting Express to the FGI!!!!
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.

Check out all of the latest events, news, and industry happenings.
This first webinar Panel Discussion will assemble five (5) industry leaders to answer questions about design, specifying, factory testing, fabrication, welding, packaging, shipping, installing, field leak location testing, and maintaining factory fabricated geomembranes and geosynthetics, e.g., geotextiles, for a range of applications. The panelists will also discuss different labor rates, production per day, quality control, testing, weather impacts, wind, wrinkles and performing leak location surveys, etc. for factory fabricated versus field fabricated geosynthetics. This should result in a lively discussion about current trends in geomembranes, fabrication, testing, and installation.

The Fabricated Geomembrane Institute (FGI) is pleased to welcome its newest Government/Regulatory Agency Member, Tennessee Department of Environment and Conservation, Division of Solid Waste Management.
The mission of the Division of Solid Waste Management (DSWM) is to protect, improve, and promote health and environmental quality through the responsive, effective oversight of waste management activities and the beneficial use of recovered materials. Solid waste may be defined as any useless,unused, unwanted, or discarded materials. Hazardous waste, problem waste, toxic substances, and recyclables may be distinguished from other solid waste. DSWM has established focused programs to address each of these. The Solid Waste Program ensures safe and sanitary processing and disposal of solid waste in Tennessee. It regulates material recovery facilities, transfer stations,and landfills for sanitary or municipal solid waste, industrial waste, farming wastes, and construction and demolition waste, some of which are subject to EPA RCRA Subtitle D. The Solid Waste Program operates under the authority of the Solid Waste Management Act of 1991.
The FGI liaison is Reese Yontz, who can be reached at email@example.com. Please help us welcome the Tennessee Department of Environment and Conservation, Division of Solid Waste Management to the FGI!!!!
In addition to the FGI’s Audio Podcast Series, the FGI has now created a series of Video Podcasts. The video podcasts are approximately 10-20 minutes long and demonstrate a technical aspect of the geosynthetics industry. For example, two video podcasts cover the FGI’s new Panel Weight Calculator and Pond Liner Calculator. The videos review the purpose and usefulness of these calculators, as well as a tutorial on how to use them. Another video podcast reviews a case history on a slope failure and features special guest, Doug Evans of the Ohio Department of Natural Resources.
All of the FGI’s Video podcasts can be downloaded for free from the FGI website HERE.
If you have a topic for the FGI to address on a future audio or video podcast, please email Jen Miller at firstname.lastname@example.org
