Next GSI webinar Oct. 12
October 3rd, 2016
“MSE wall back drainage design” is the topic for the October webinar presented by the Geosynthetic Institute—Wednesday, Oct. 12, 11:30 a.m.–1 p.m. (ET). Webinar Overview Within GSI’s database of 171 failed mechanically stabilized earth (MSE) walls reinforced with geogrids or geotextiles, 60% have failed due to water. Furthermore, 61% have been constructed with fine grained […]
GSI’s August webinar: ‘How long will they last?’
August 4th, 2016
On Wednesday, August 10, the Geosynthetic Institute will present one of its most-popular webinars: “Lifetime Predictions of Nonexposed and Exposed Geosynthetics.” A most-frequently asked question regarding all types of geosynthetics is, “How long will they last?” This webinar answers the question for exposed geotextiles and geomembranes assuming that they were properly designed and installed. It […]
