Amy Woods Recognized by Women in Geosynthetics

This month, we’re launching our new ✨Member Spotlight✨ program. Every month, we will honor one of the awesome women in the Geosynthetics industry. This months nomination is Amy Woods with Titan Environmental Containment & Titan USA ! Amy is a Technical Product Manager at Titan Environmental Containment. She has over 20 years of experience working in the geosynthetics field in both public and private sectors including municipal government, consulting and construction supply. She has spent the last 8 years focused on stormwater management and green infrastructure working with Contractors, Engineers and Owners to design solutions for low impact development projects. She is particularly passionate about protecting and enhancing the natural environment and using engineering techniques and new technologies to optimize this. She has managed projects in just about every region within Canada and the US and currently resides just outside of Toronto, Canada with her husband, two children and their new puppy.

Amy was nominated by a fellow WIG member. When asked why we thought she would make a great spotlight, the individual said “Amy was integral to my growth in the geosynthetics industry and really nurtured the idea of maintaining assertiveness in order to achieve growth within the company. I’ve seen Amy handle all types of situations and personalities with extreme grace. She’s such a talented and experienced Stormwater industry leader. The amount of projects that Amy has tackled single handily blows my mind, and she always took the time out to speak with me on a personal level, and get me the material I needed in a timely manner on a professional level.”Awesome work Amy! We’re so lucky to have you a part of our industry and a key WIG member!

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!!

FGI Welcomes GeoSolutions

The Fabricated Geomembrane Institute (FGI) is pleased to welcome its newest fabricator, GeoSolutions. GeoSolutions was founded in 1999 on the premise that the market would respond favorably to a solution-centric, customer-driven offering versus a simple material supply house. GeoSolutions is focused on the client’s needs to solve site construction problems with the most recent technologies and products that will save time and money and improve performance. GeoSolutions provides our customers with unmatched geotechnical products and engineering solutions that allow them to successfully complete projects of any size and level of complexity. Their solutions offer value-added answers to traditional problems associated with sitework, stormwater management, erosion & sediment control, and grade separation/earth retention.

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 or Please help us welcome Aquamate to the FGI!!!!
