Fabricated Geomembrane Installation GuidelinesThe International Association of Geosynthetic Installers (IAGI) and the Fabricated Geomembrane Institute (FGI) both have a long history of establishing field-improving protocols, such as certifications and standard. Now, they have created a joint project on geomembrane installation. The result is the release of three guidelines ready for immediate use by the field.
Focused on factory-fabricated geomembranes, the three installation guidelines are segmented by 25-mil lightweight products, 25-mil heavyweight products, and unsupported products of 10 – 60 mil thichkness.
The guidelines are openly available at www.iagi.org, along with other industry resources. Copies of individual documents may also be downloaded in PDF below:

The current versions replace those distributed in 2013 and 2014.
