Geomembrane Installation Guidelines Available

The International Association of Geosynthetic Installers (IAGI), in its effort to provide a forum for geosynthetics installers to advance installation and construction techniques, has made available current installation guidelines.

IAGI along with the Fabricated Geomembrane Institute (FGI) collaborated to produce three installation guidelines that address; factory fabricated lightweight 0.64-mm (25 mil) geomembranes; factory fabricated heavyweight 0.64-mm (25 mil) geomembranes; and factory fabricated compounded 0.25- to 1.52-mm (10 to 60 mil) thickness unsupported geomembranes. All of these guidelines can be found at IAGI’s website. 

The Guideline for Installation of Factory Fabricated Lightweight < 0.64 mm (25 mil) 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). This guideline is designed to provide a minimum set of standards for site installation. 

The Guideline for Installation of Factory Fabricated Heavyweight > 0.64 mm (25 mil) Thickness Geomembranes is an installation guideline for factory fabricated fabric-supported heavyweight geomembranes (> 0.64 mm or > 25 mil in thickness as measured by ASTM D5199, D751 or D1777.) This guideline is designed to provide a minimum set of standards for site installation. 

The Guideline for Installation of Factory Fabricated Compounded 0.25 to 1.52 mm (10 - 60 mil) Thickness Unsupported Geomembranes is an installation guideline for factory fabricated compounded unsupported geomembranes of 0.25 to 1.52 mm (10 - 60 mil) 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; Ethylene Propylene Diene Monomer (EPDM). This guideline is designed to provide a minimum set of standards for site installation.
