The Fabricated Geomembrane Institute (FGI) at the University of Illinois at Urbana-Champaign has created a library of Geomembrane Test Method Videos that explain various factory and field test methods. Testing videos available to view/download include demonstrations on how to measure the following: thickness, tensile strength, dimensional stability, seam shear and peel strength, and brittleness.
The FGI has recently recorded two new testing videos, as part of the Geomembrane Test Method Library on the FGI website: ASTM D1204 Dimensional Stability and ASTM D1790 Brittleness Temperature of Plastic Sheeting by Impact.
In addition to these two testing videos, the FGI has recorded the following testing videos available to view/download:
ASTM D7408 Seam Peel Strength
ASTM D882 Tensile Properties Geomembranes
ASTM D7408 Seam Shear Strength
ASTM D5994 Thickness Textured Geomembrane
ASTM D5199 Procedure B Thickness Smooth Geomembrane
