Colorado Lining International Gives Back on Earth Day

Earth Day officially takes place on Saturday, April 22, 2023. Viaflex, a member of the Fabricated Geomembrane Institute, (FGI) charged each of their locations to participate in Earth Day this year. Therefore, Colorado Lining International, (CLI) a subsidiary of Viaflex located in Parker, Colorado, decided to participate in the Adopt a Flower Bed Program.  Several members of the CLI team adopted a low water use xeriscape garden.  CLI has already completed a thorough cleanup of the site and now plans to plant the flower bed.  In addition, the team has committed to spreading mulch and keeping the garden free from weeds.  Way to go, CLI!!

Dr. Stark Visits El Toro Water Reservoir Project in Mission Viejo, California

On March 2, 2023, Tim Stark visited the replacement liner and floating cover system for the El Toro Reservoir in Mission Viejo, California. This is a joint reservoir project between three water districts that is providing emergency water supply, storage, and cost savings to south Orange County water customers. The reservoir holds 275 million gallons (1.04 billion liters) of potable water.  The reservoir was originally constructed in the 1960’s as an open reservoir.  The first geomembrane floating cover was installed in the early 1980’s. In 2001 a composite geosynthetic liner and reinforced polypropylene floating cover was installed.  After 20 years, the existing liner is being augmented with a new 60 mil (1.5 mm) CSPE geomembrane that is being placed on top of the existing 70 mil (1.8 mm) reinforced polypropylene (rPP) geomembrane, which is still in intimate contact with the underlying subgrade (see Figure1). The resulting bottom liner system is shown in Figure 2.  

The main impetus for the project is replacing the 45 mil (1.1 mm) rPP floating cover system, which had exceeded its service life. The old cover system is being discarded and replaced with a 45 mil (1.1 mm) CSPE geomembrane based floating cover based on a requirement for an extended 30 year weathering warranty and long term material history. The project involves installing about1.1 million square feet (102,000 square meters) of geomembrane for the bottom liner system and about 1.15 million square feet (107,000 square meters) for the floating cover system as well as updating the reservoir interior valves, site drainage piping, and electrical upgrades. Douglas Hilts of Hilts Consulting Group is the design engineer, and the Layfield Group is the fabricator and installer of the liner and floating cover system geosynthetics. This project illustrates the advantages of factory fabricated panels because one panel extends from the top of the reservoir to the floor down slope over 325 feet where it is seamed with floor panels.

Dr. Stark hopes to visit the facilities of all FGI members 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.

FGI Welcomes Aquamate

The Fabricated Geomembrane Institute (FGI) is pleased to welcome its newest Fabricator/Installer Member, Aquamate.  Aquamate manufactures a proprietary range of premium factory fabricated water tanks. The tanks are flat packed and shipped to sites across Australia and the US and assembled on site by trained crews. Aquamate was established in 1986 to repair leaking concrete tanks that were failing due to a variety of reasons including natural ground movement, poor workmanship or lack of correct materials available during installation. A solution to these problems was found when Aquamate installed its first kit form polymer lined steel tank. The tank was easily transported to site, constructed in a day in most cases and remained impervious to any natural ground movement. The company headquarters is in Adelaide, South Australia and their FGI liaison is Danny Di Iorio, Chief Executive Officer, who can be reached at danny.diiorio@aquamate.com.au or www.aquamate.com.au.

FGI Legacy and History: Celebrating Nearly 40 Years of Innovation in Geomembranes

Written by Brian Fraser & Pat Elliott – October 28, 2025
Download

Geomembranes have played a vital role in environmental containment across North America for over six decades. Their journey began in1957 when the U.S. Bureau of Reclamation conducted early tests on PVC geomembrane installations. A landmark moment came in 1968 with the first formally specified PVC geomembrane installation for Montana’s Helena Valley Canal marking the beginning of a new era in engineered containment solutions.

The Fabricated Geomembrane Institute (FGI) traces its roots to the PVC Geomembrane Institute (PGI), founded in 1988. PGI was established to represent a growing community of manufacturers, fabricators, and installers dedicated to advancing geomembrane technology. In 2009, recognizing the expanding scope of factory-fabricated materials, PGI rebranded as FGI. This shift emphasized the advantages of controlled factory production over field fabrication, aligning with industry trends and technological advancements.

FGI is housed within the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign. As an academic-industry consortium, it is committed to research, education, and technology transfer in the field of flexible geosynthetics. In June 2025, the institute adopted a new name—Flexible Geomembrane Institute—to reflect its broadened mission, which now includes both roll stock and field-fabricated liners.

Mission and Vision
FGI operates as a non-profit, industry-sponsored institute focused on advancing the use of flexible geomembranes. Through collaborative research, educational outreach, and technical guidance, FGI has become a cornerstone of innovation and knowledge-sharing in the geosynthetics community.  Professor Timothy D. Stark, Technical Director of the FGI, and the Board of Directors remain committed to advancing and growing the association while providing a high level of support to our members.

Honoring the Pioneers & Contributors
As FGI approaches its 40th anniversary, we extend heartfelt gratitude to the many individuals who have shaped both the institute and the broader geomembrane industry. From early pioneers to long-standing supporters, your contributions have left a lasting legacy. While the list is extensive, we acknowledge that some names may be inadvertently omitted and offer our sincere apologies.
