News and Articles

By Chris Kelsey – During GeoAmericas 2016, Dr. Neil Dixon’s sustainability keynote touched upon many topics for the future of geosynthetics. While sustainability drove most of the lecture, a few of his ideas simply approached how the field positioned itself in the marketplace. He suggested, for example, moving the field away from isolating language like “versus traditional materials.” With 4... »

In March 2014, I published “A Brief History of Geotextiles” in Land and Water Magazine. (A copy of that article may be downloaded in PDF here.) It would take a considerably long manuscript to fully detail the research, projects, events and people who have brought forth geotextiles, let alone the larger field of geosynthetics; but a welcomed result of that small article was post-publication communi... »

The effort to get geosynthetics specifically mentioned in the Water Resources Reform and Development Act (WRRDA) extends back many years. It began, in fact, roughly seven years ago following the passage of the last major water resource bill. The Geosynthetic Materials Association (GMA) had drafted a strategic plan in 2004 that identified a need for a stronger voice at the federal government policy... »
