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.
