Vote opened a week ago for IGS members to elect their next president. https://www.geosyntheticssociety.org/igs-council-candidates-2026/ While the choice for the best candidates is hard, the process is somehow even harder and must be explained! Here you go: 1-    You must be a member of the IGS , usually by being a member of the IGS Chapter for your country. This requires you to have paid your annual membership fee. If you have recently renewed your membership, please require

EuroGeo 8, Lille, France Publication by Eric Blond, Jean-Pierre Giroud, and John Scheirs Abstract Geomembranes, and their seams, are exposed in the field to tensile loads and elevated temperatures. The tensile-shear strength of bituminous geomembrane seams was assessed through laboratory testing under temperatures ranging between 23 and 80°C. Constant-load (creep) tests were conducted under temperatures ranging between 23 and 60°C to measure the seam separation rate and failu

EuroGeo 8, Lille, France Publication by Eric Blond and Catrin Tarnowski Abstract One of the techniques commonly used to create a surface texture on a polyethylene geomembrane consists in spraying filaments on a smooth geomembrane. When adequately produced, this solution provides a geomembrane exhibiting good friction properties, while preserving the mechanical and durability properties of the base, smooth geomembrane. In the first part of the paper, key aspects related to the

GeoAsia Conference Paper by Eric Blond, Jean-Pierre Giroud and John Scheirs Geomembranes, and their seams, are exposed in the field to tensile loads and elevated temperatures. The shear strength of bituminous geomembrane seams was assessed through laboratory testing under temperatures ranging between 23 and 80°C. Constant-load (creep) tests were conducted under temperatures ranging between 23 and 60°C to measure the seam separation rate and failure time as a function of tempe
