Factory fabrication can result in shorter construction time (and costs), higher seam quality, and a better completed liner system. Most fabricated geomembranes are less susceptible to wrinkling due to better dimensional stability, bending modulus, and flexibility which leads to better intimate contact with the subgrade and less risk of damage or wrinkle entrapment during soil covering. The webinar will focus on factory and field quality assurance and control testing, e.g., seam testing and as well as seam shear and peel strength testing, and developing panel sizes. The use of leak location surveys prior to and/or after soil covering also will be discussed
About the Presenter
Timothy D. Stark, Ph.D., P.E.
University of Illinois at Urbana-Champaign
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, for the last twenty-five (25) years. 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), which is an industry sponsored research organization investigating the advantage and disadvantages of geomembranes for containment and seepage applications.
