The Fabricated Geomembrane Institute (FGI) is presenting a two-part Short Course on Subgrade Preparation & Use of Geosynthetic Clay Liners (GCLs) for Flexible Geomembranes. The short course will be held Tuesday, April 9, 2024 12-1:30 pm CDT and Wednesday, April 10, 2024 12-1:30 pm CDT. The course is free, a 3.0 PDH is available and you can register here.
Part 1 of the online short course will focus on subgrade preparation for flexible geomembranes. This course will describe the requirements for subgrade preparation before a flexible geomembrane is installed, such as maximum rock size allowed, presence of water, degree of compaction, moisture content, compactive effort, and smooth rolling the surface before geomembrane installation. Quality control techniques for checking the subgrade compaction will also be discussed.
Part 2 will focus on the use of geosynthetic clay liners (GCLs) with flexible geomembranes to create a composite barrier system. This webinar will be helpful for those who are new to working with geosynthetics or those who can use a refresher. The course will provide a comprehensive overview of GCLs and their use with overlying flexible geomembranes. Specifically, this webinar will present design considerations, testing, and installation of GCLs. We’ll review hydraulic and chemical properties as well as shear strength and slope stability. You’ll have an overview of important criteria to consider during the design process for a successful bottom liner system installation.
The presenters are Timothy D. Stark, Ph.D., P.E. (University of Illinois) and Marat Goldenberg, P.E. (CETCO).
Dr. Timothy Stark is a professor in the Department of Civil Engineering at the University of Illinois at Urbana-Champaign. Dr. Stark has been conducting interdisciplinary research on geosynthetics and in particular geomembranes. This includes his research on the installation and long-term durability of geomembranes and other geosynthetics in geo-environmental and seepage applications. He is the technical director of the Fabricated Geomembrane Institute (FGI), an industry sponsored research organization investigating the advantages and disadvantages of flexible geomembranes for containment and seepage applications.
Marat Goldenberg is a technical sales manager for CETCO and a licensed professional engineer with 13 years of experience. Marat’s previous experience at CETCO includes product development, manufacturing oversight, quality control oversight, and content development. Marat also served as an environmental consultant with experience evaluating remedial alternatives, engineering design and procurement, wastewater treatment, and construction oversite on large-scale environmental remediation projects.
