The International Association of Geosynthetic Installers (IAGI) issued a press release this week “in its continuing effort to provide a forum for geosynthetics installers to advance installation and construction techniques has made available current installation guidelines.”
IAGI and the Fabricated Geomembrane Institute (FGI) collaborated to produce three installation guidelines that address factory fabricated lightweight 0.64mm (25mil) geomembranes, factory fabricated heavyweight 0.64mm (25mil) geomembranes, and factory fabricated compounded 0.25 to 1.52mm (10 to 60mil) thickness unsupported geomembranes. The press release noted that all of these guidelines are available at www.iagi.org.
The Guideline for Installation of Factory Fabricated Lightweight < 0.64mm (25mil) Thickness Geomembranes is an installation guideline for factory fabricated fabric-supported lightweight geomembranes (< 0.64mm or < 25 mil in thickness as measured by ASTM D5199, D751, or D1777). The Guideline for Installation of Factory Fabricated Heavyweight > 0.64mm (25mil) Thickness Geomembranes is an installation guideline for factory fabricated fabric-supported heavyweight geomembranes (> 0.64mm or > 25mil in thickness as measured by ASTM D5199, D751, or D1777).
The Guideline for Installation of Factory Fabricated Compounded 0.25 to 1.52mm (10 to 60mil) Thickness Unsupported Geomembranes is an installation guideline for factory fabricated compounded unsupported geomembranes of 0.25 to 1.52mm (10 to 60mil) thickness. The geomembranes covered in this guideline include the following polymers: chlorosulfonated polyethylene (CPSE), polyvinyl chloride (PVC), and alloys of PVC with other polymers, alloys with ethylene interpolymer alloy (EIA), alloys with nitrile or other types of rubber, blends and alloys with other compatible polymers, and ethylene propylene diene monomer (EPDM).
The press release stated that these guidelines are designed to provide a minimum set of standards for site installations.
Founded in 1995, IAGI is the professional association representing geosynthetic material installers and their industry partners.
