GMA and FGI to host part 2 of a webinar on the stability of geosynthetic lined slopes

GMA News, News | May 15, 2018 | By:

The Geosynthetic Materials Association (GMA), in collaboration with the Fabricated Geomembrane Institute (FGI), will present the second of this two-part, free webinar series on May 31, 2018, at 12:00 p.m. EDT. The webinar will discuss the importance of geosynthetic interface strengths on slope stability, when to use peak and residual geosynthetic interface strengths, how to develop minimum shear strengths for specifications, measurement of geosynthetic and geosynthetic clay liner interface strengths using single and multi-interface tests, and how to develop a shear testing work plan for a commercial laboratory that yields meaningful data.

Those involved with the design, specification, permitting and construction of geosynthetic lined slopes will find these webinars beneficial.

The webinar will be presented by Timothy D. Stark, Ph.D., a professor of civil and environmental engineering at the University of Illinois at Urbana-Champaign. Stark is also the technical director of FGI. The webinar will be moderated by Andy Durham, a senior geosynthetics engineer with Owens Corning.
