The International Association of Geosynthetic Installers (IAGI) has developed and implemented two programs designed to assist engineers, owners and regulators in improving geosynthetic installations on their job sites. The purpose of the paper is to update the geosynthetic users about the Certified Welding Technician and the Approved Installation Contractor programs. Both of these programs were developed by IAGI to raise the level of professionalism and improve the quality of geosynthetic installations. IAGI ‘s goal is for engineers and regulators who work with geosynthetic installers on their job sites to embrace these programs and require that Approved Contractors be used on their job sites. This paper and presentation will discuss the specifics of each program. IAGI‘s Certified Welding Technicians program tests the skills and knowledge of the geomembrane welders who put liner into landfills, landfill caps and wastewater treatment facilities. The second program, which has been launched by IAGI, is the Approved Installation Contractor program. This program sets a minimum level of standards that installation companies must meet to become an Approved Installer. The purpose of this paper is to inform engineers, owners and regulators about the advantages of requiring that the installers who work on the containment sites employ Certified Welding Technicians and participate in the Approved Installation Contractor program. The International Association of Geosynthetic Installers is a group of geosynthetic installers dedicated to advancing the state of the practice in the industry. We welcome all stake holders as members of our organization.
