IAGI – International Association of Geosynthetics Installers
DDT Liners is a Founding Member of the International Association of Geosynthetics Installers. IAGI was established to …” provide a forum for Geosynthetics Installers to advance installation and construction techniques, and to strengthen the knowledge, image, and communication within the industry…”.
We support IAGI’s Aims and Objectives, and we follow IAGI specifications for Installation, where no other job specific “Spec” exists. The IAGI specification can be downloaded for free from their website – www.iagi.org
IAGI provides a platform for geosynthetic installers to obtain recognition within the industry via the “Certified Welding Technician” program. CWT was introduced to verify and recognise the skills of experienced welding technicians within the industry.
To become a CWT, a candidate must pass both a written exam to assess industry knowledge and a practical exam to demonstrate welding competency. A resume confirming their industry experience is also vetted at the time of application.
Even if you choose not to use DDT Liners for your next liner job, we strongly advise that you choose an IAGI Member Installer with CWT personnel and that as a minimum they follow the IAGI specification.
