GWFV walls and slopes
October 1st, 2017
New patented technology is available to construct geosynthetic wrap-face vegetated (GWFV) retaining walls and reinforced soil slopes using a pyramidal-woven, high-performance turf reinforcement mat (HPTRM) in conjunction with fiber-composite internal braces. This wrap-face system eliminates the need for temporary external bracing (formwork) or for facing elements comprised of metallic wire-frame units, which traditionally have served […]
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 […]
Panorama: ASTM D35.06 on Geosynthetic Specs takes shape
October 1st, 2017
At the January 2017 meeting of the ASTM International Committee D35 on Geosynthetics in Norfolk, Va., the executive subcommittee approved the formation of a new subcommittee D35.06 on Geosynthetic Specifications with L. David Suits as chair. The scope of D35.06 is to implement the scope of Committee D35 with a focus on the development of […]
Part 2: The regulation of CCR in the United States: Geosynthetics and barriers
October 1st, 2017
As discussed in Part 1 of “The Regulation of CCR in the United States,” for the first time in decades, nationwide regulation of CCR (coal combustion residuals) surface impoundments expands the regulated use of geosynthetic materials. While the CCR Rule (2015) allows continued operation of existing CCR surface impoundments, it provides criteria for the disposition […]
