Protecting geomembranes from animal damage
June 1st, 2017
Resisting animal and insect attacks on geomembranes is an interesting problem. Geomembrane installers and manufacturers have had numerous geomembranes damaged by bears, deer, coyotes, birds, beavers, and ground squirrels (Figures 1 and 2). In most cases, the damage is incidental to something else the animal is seeking. Deer damage the liner with their hooves trying […]

Part 1: Functions and applications of geosynthetics in roadways
February 1st, 2017
Introduction The geosynthetic products most commonly used in roadway systems include geotextiles (woven and nonwoven) and geogrids (biaxial and multiaxial), although erosion-control products, geocells, geonets (or geocomposite drainage products), and geomembranes have also been incorporated in a number of projects. These various types of geosynthetics can be used to fulfill one or more specific functions […]

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 […]
