On December 4, Dr. Jie Han (University of Kansas) will present the next IGS North America webinar. His topic: "Recent Developments in Geosynthetic-Stabilized Roads: Introduction and Mechanisms." The free event is part of the new IGS North America - GMA webinar series. Time for the presentation will be 1:00 - 2:00 pm EST. REGISTER NOW GEOSYNTHETIC-STABILIZED ROADS Geotextiles, geogrids, and geocells have been used...

David Butchart has returned to the geotechnical engineering field in a new business development and strategy role with Earth Wall Products, LLC. The company provides proprietary retaining wall systems and materials for use in the construction of earth retaining walls. Some of the systems for which Earth Wall Products is known include the GRAVIX and FORIX gravity systems and...

By Namrata Bichewar – Prefabricated vertical drains are geocomposite drainage materials with an inner core of polypropylene wrapped in a nonwoven geotextile filter fabric. TechFab’s TechDrain PVDs are jointless versions of this high-performing class of products. The brand is available in corrugated and fishbone varieties. All PVDs should have high permeability and a sufficiently high drainage capacity so that pore water escapes...

The North American Chapter of the International Geosynthetics Society (IGS North America) has established an Excellence in Service Award to recognize members who have shown outstanding leadership and dedication to the objectives of the chapter or the geosynthetics industry. The inaugural IGS North America Service Award (or awards) will be issued at Geosynthetics 2019. The event, to be held 10...

The Berlin 2 geomembrane workshop, held 26 September 2014 in Germany, gathered engineering experts from around the world and who represented multiple perspectives in geosynthetics. The goal was to develop a protocol for better anticipating the end of life--to define end of life--for an exposed, high-density polyethylene geomembrane that is actively in service.

The City of Calgary wanted to reduce construction and maintenance costs of concrete pedestrian sidewalks. The traditional approach used by the city was to use thick, unreinforced concrete slabs. Yearly rehabilitation work was required to repair major cracking of the slabs shortly after installation. Project planners looked for a reinforcement system that would not be susceptible to corrosion and...

Mines depend on consistent access for site safety, operational efficiency, and profitability. Delays in access can quickly cost active mines millions of dollars in lost production, and that can determine the fate of a site’s continued operation. In Northern Ontario, mine haul roads on composite geogrids have proven to be a highly effective strategy to keep mines running. MINE HAUL...

The geosynthetics industry’s global growth has drawn the interest of an increasing number of market research organizations. Reporte’s latest analysis of the world geogrid market, Global Geogrids Market 2018, included a competitive analysis of 31 international companies. Canada-headquartered Titan Environmental Containment, which has been growing wildly in the past five years across many sectors and especially with its TE...
