The durability of exposed geomembrane covers
October 1st, 2017
The most frequently asked question by people in the geosynthetics world is how long is the anticipated lifetime of geosynthetics. So much so that of the more than 3,000 questions submitted to the GMA Techline since it began in 2004, 591 (19.7%) have been on lifetime, aka durability. Of these, 49% were on buried lifetime, […]
Editorial: Geosynthetics for multiple applications
October 1st, 2017
If you are reading this publication, you obviously have an interest in geosynthetics, as this magazine is unlikely to appeal to people whose primary professional interests are taxidermy, snow-crystal study or calligraphy. We aim to please, and this issue touches on many types of geosynthetics, from geogrids to geomembranes, and many applications of geosynthetics, from […]
