IAGI Certification Preparation Course

It is the certification of experience, knowledge and skills for welders of polyethylene geomembrane, reinforced PVC and EPDM to comply with industry standards.

What is the IAGI Certification?

Founded in 1995, the International Association of Geosynthetic Installers is the professional association that represents the installers of geosynthetic materials and their industrial partners.
These founders created a solid organization that evolved and continues to meet the needs of the industry 18 years later.
The IAGI Certified Welding Technician (CWT) program recognizes the knowledge, experience and skill of technicians who are certified.
Engineers benefit from the IAGI CWT program because the certification verifies that welders have experience in geomembrane welding and meet industry standards for the installation of geomembranes in which they are certified.
IAGI encourages all engineers to require that any welding performed at their workplace be applied by CWT (CertifiedWeldingTechnician) personnel.

IAGI developed the certification programs for polyethylene, reinforced PVC and EPDM geomembrane welders so that installers can define competency standards, recognize installers’ knowledge, experience and skills and reward those who qualify with industry recognition.

Member companies that have invested resources in training and certification of their welding technicians take pride in the skill of their welding technicians.
IAGI encourages you to use companies that have made this commitment to quality in your next job!
