Guideline for Subgrade Preparation for Fabricated Geomembranes is Published
by FGI
(St. Paul, Minn., July 10, 2010) The Fabricated Geomembrane Institute (FGI) has produced a new guideline entitled Subgrade Requirements for Fabricated Geomembranes. This guideline details the proper preparation of the subgrade for the installation of all fabricated geomembranes. This document is written such that these guidelines can be picked up by an engineer or specifier and put into a specification for subgrade condition and requirements. Color pictures of both acceptable and unacceptable subgrade preparations and protrusions are provided to give the user a visual depiction of what is described in the text.
The subgrade requirements for preventing water pressure build-up below the liner are addressed in this guideline. This is an important consideration in preventing the geomembrane from being lifted off the subgrade by ground water or gas build up. This document can be found here and is available for use by the industry.
The Fabricated Geomembrane Institute is housed at the University of Illinois at Urban-Champaign. Dr. Timothy D. Stark is a Professor of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign with an expertise in Geotechnical Engineering. Dr. Stark has been teaching, researching, and consulting on geosynthetics, stability of manmade slopes, and design of waste containment facilities for more than 15 years. For more information on the FGI, contact Dr. Stark at +1 217-333-3929 or geomembrane@illinois.edu.
Advances in Geotechnical Engineering
The objective of Geo-Frontiers 2011 is to share new developments in geotechnical engineering technologies. Attendees will be exposed to the latest state of the art and practice as applied to geotechnical engineering.
As an engineer, environmental specialist, water or transportation regulator, you will have an extensive menu of technical programs, workshops and short courses to select from. You’ll walk away with up to 32 pdhs, hundreds of new ideas—from design and engineering strategies to cost-saving geotechnical solutions and new industry contacts.
Technical Paper Program
Abstract submission has closed with 800 abstract submissions. The review process is underway.
Trade Show
If your market is geotechnical products and services you should exhibit at the largest geotechnical trade event in North America… Geo-Frontiers 2011.
• Exhibitors include manufacturers and service providers showcasing geotechnical solutions and technologies and innovations
• Exhibits will include the latest products, technologies, services and equipment for the geosynthetics industry

During a recent trip, Tim Stark visited the headquarters of the Seaman Corporation in Wooster, Ohio. Tim met with Joe Gaspro, Marketing Manager (see attached photograph), and Bill Shehane, Geomembrane Marketing Specialist, via WebEx to discuss current and future FGI activities and the geosynthetics industry as a whole.
Dr. Stark hopes to visit the facility of all FGI members in the near future to better understand each member’s business and how the FGI can provide additional benefit to them. The FGI is an exciting advancement in the geomembrane industry and allows the Institute to focus on all geomembranes that can be factory fabricated.

During a recent trip, Tim Stark visited the newest member of the FabricatedGeomembrane Institute (FGI) Hapco, Inc. in beautiful Kent, Ohio. Tim met with Chuck George, CEO, and Brenda Solon, Marketing Consultant, to discuss current and future FGI activities (see attached photograph). Tim also met with other Hapco employees and toured their extensive equipment development and repair facilities. In particular, the involvement of Hapco in the welding and testing demonstration in the next FGI short course that will be held at the Embassy Suites Hotel in Denver on Friday, October 15, 2010 was discussed as well as how the FGI can assist Hapco.
