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.

Evaluating the Effects of Elevated Temperatures on Geomembranes & Welding
This article discusses some of the growing concerns and impacts associated with high-temperature geomembrane applications and welding temperatures.
The use of geomembranes in elevated-temperature applications is increasing due to rising ambient global temperatures, expanded use of geomembranes in hot arid regions and the need to contain heated liquids in industrial, mining, energy, and waste management operations. .
