Project Spotlight

Golf Course Irrigation Ponds in Mexico

MEMBER COMPANY: 
MEMBER COMPANIES: 

Leak Location Services, Inc.

APPLICATION:

Golf Course Irrigation Ponds

PROJECT OVERVIEW:

Golf course irrigation ponds are one of the first items that are installed when a golf course is constructed (see Figures 1 and 2). The grass for each hole requires the irrigation pond to be constructed and be leak free before grass sod can be laid. It is important that these ponds do not leak because the beauty of the course relies heavily on water and this water comes from these irrigation ponds. The ponds are not overly large and are single lined with a 60-milthick Woven Coated Polyethylene Geomembrane. The perimeter of the ponds are decorative and therefore when full will look like natural ponds with a rock and concrete border around the perimeter of the pond. Inside the ponds the geomembrane is covered with approximately 1.5 feet (0.5m) of sand along the floor and up the side slopes (see Figure 2). The sand maybe reinforced with geocells as shown in Figure 2This sand connects with the concrete perimeter of the pond and therefore little, if any, of the geomembrane is exposed.

The FGI is proud to highlight our members' projects utilizing fabricated flexible geosynthetics. Check out some of the creative projects, understand why certain products were selected, and read the project descriptions as well as the important lessons learned.

Exciting News for the FGI: We’re Now the Flexible Geomembrane Institute

After sixteen years as the Fabricated Geomembrane Institute (FGI), we’re proud to announce that we have officially changed our name to the Flexible Geomembrane Institute. This change marks an exciting new chapter for our organization, expanding our mission and further solidifying our commitment to the innovative field of geomembrane technology, while maintaining focus on factory fabrication and modular construction.

This updated name better reflects the evolving landscape of the industry and the diverse needs of FGI’s growing community of members and industry professionals. By emphasizing flexibility, our new name speaks to the Institute’s broader reach, while staying true to the foundational principles and deep expertise in geomembrane applications.

"Expanding the FGI to focus on all flexible geomembrane installations allows us to include field fabrication with our long-term interest in factory fabrication and modular construction," said Dr. Timothy D. Stark, Technical Director of FGI. "As we continue to innovate and grow, we are still the same great organization, providing useful content on current and emerging trends in the industry." Patrick Elliott, President of the FGI also commented, “This simple but strategic change helps align our goals and work closer to represent the needs of our members and industry. While our core focus will always be on factory fabrication the fact remains, we want to provide industry research and technology to focus on providing the best products and techniques to solve all project challenges.”

New Domain, Same Valuable Resources
Alongside the name change, FGI has announced a new domain name. Our website is now located at www.thefgi.org. Visitors will continue to find the same valuable content, resources, and educational materials, with the added benefit of a shorter and easier domain name. For any inquiries, please contact Jen Miller at her new email address Jen@thefgi.org.

Please join all of us with the FGI in celebrating this exciting advancement.
