Frequently facilities accept special wastes from cleanup projects, sludge generators, and/or stabilization processes. The shear strength of the special wastes must be estimated and included in stability analyses to ensure slope stability. This webinar will present recommendations for shear strength testing, specimen preparation, and strength criteria for characterizing special wastes, conducting stability analyses, and landfill handling, placement, and operations to promote slope stability.

The FGI is hosting a workshop for its members to discuss the marketing and promotion of fabricated geomembranes and the future of the FGI.  This workshop will focus on these two (2) topics in a round table type of discussion:

Marketing & Promoting Fabricated Geomembranes

- Why modular construction

- How to improve the fabricated message/industry

- Why is factory fabrication better

- Fabrication saves money

- Different labor rates

- Geomembrane wrinkles and thermal expansion– no leak location, stress cracking, tears duringcover soil

- Reinforced GMs – construction, operation, filling, cleaning, tensile stresses

- Chemical Resistance – Subtitle D

‍

Future of the FGI

- More research

- More webinars

- More members

- Topics/Content – moretesting videos, short courses, summer internships

‍

Attendees will gain a broad knowledge of current and emerging CCR regulations, local experience managing CCRs, and the advantages of using geosynthetics to manage and dispose of CCRs.  Course attendees will earn seven (7.0) PDHs. Lunch and break refreshments will be provided.

This webinar will discuss how and the types of geomembranes that can be primarily factory fabricated and transported to the field for installation and testing. Factory fabrication results in shorter construction time (and costs), more modular construction, higher quality seams (data will be presented), less patches, and a better completed liner system than field fabricated geomembranes.  The types of geomembranes that are suited for factory fabrication and folding also are less susceptible to wrinkling after installation and before soil covering, which facilitates leak location surveys and cover soil placement.  This webinar will focus on factory and field quality assurance and control testing, e.g., seam air channel testing as well as seam shear and peel strength testing.  The use of leak location surveys prior to and/or after soil covering also will be discussed.
