International Association
of Geosynthetics Installers
Professional Installers. Professional Installations.
IAGI's mission is to advance installation and construction technologies as well as to provide a central clearinghouse for comprehensive industry information. We invite you to join the International Association of Geosynthetic Installers, a dynamic association of geosynthetic professionals created by and for installers.
Certified Welding Technician (CWT)
IAGI’s Certified Welding Technician (CWT) program recognizes the knowledge, experience and skill of those technicians who hold the certification.
Engineers benefit from IAGI's CWT program because certification verifies that the welders on their job have experience in geomembrane welding and meet industry standards of skill for those geomembranes they are certified in. IAGI encourages all engineers to require that any welding done on their jobsite be done with CWTs.
Approved Installation Contractor (AIC)
IAGI’s Approved Installation Contractor recognizes geosynthetic installation companies that meet a minimum level of professionalism, ethics and business practices. Approved Installation Contractors must meet requirements in the following areas: corporate history and business practices, insurance verification, safety training, and professional competence and experience.

GEOGAMES
The International Association of Geosynthetics Installers (IAGI) is thrilled to announce that the 4th GeoGames competition will take place at the 13th International Conference on Geosynthetics (ICG)!
Mark your calendars: 14 September 2026 in beautiful Montréal, Québec, Canada.
IAGI is offering sponsorships to fund this event. There are several options available to support the GeoGames. You can sign up by calling Laurie Honnigford at +1 (720) 353-4977 or by email at iagi@iagi.org.
IAGI Member Project Profiles
IAGI members set the standard for installation excellence -- and we're excited to showcase their achievements! Want to see your project here next? Contact Brian Fraser and Evan Bao to be featured. We will feature a new project each month.
This Project Profile features Comanco, who recently installed a leachate collection system at a central Florida county landfill to increase leachate storage capacity and provide preliminary treatment prior to discharge to the wastewater treatment plant.

Critical vs. Non-Critical Geomembrane Containment
The distinction between critical and non-critical containment has become an increasingly important topic with the civil engineering and geosynthetic industry. With thousands of different fluids, slurries, and chemicals in use today ranging from simple water to highly corrosive or hazardous compounds, determining the environmental risk associated with each substance can be challenging. Fortunately, regulatory agencies in many regions of the world are now more clearly defining how these fluids must be classified, managed, and contained. As enviromental expections rise globally, the industry continues to refine the way containment systems are regulated, designed, and constructed to ensure long-term performance and environmental protection. This article discusses the applications of non-critical versus critical containment and the subcategory of extreme critical containment.
