New IGS Technical Committee on Stabilization using Geosynthetics

While the technical activities of the IGS have always been intense and productive, it is only since 2010 that the IGS formalized the creation of IGS Technical Committees. These comparatively new IGS operating units operate under the direct oversight of the IGS Council. Thus, in addition to the many technical activities of the IGS chapters, conferences and journals, IGS members could join a committee highly focused on technical content.


The first three IGS Technical Committees were approved by the IGS council during its May 2010 meeting in Guarujá, Brazil. Specifically, three IGS TCs were created at that time: TCs on “Reinforcement,” “Barrier Systems” and “Filtration.” Subsequently, the IGS council approved the creation of the TC on “Hydraulic Applications: Drainage, Erosion Control, Coastal Protection” (TC-Hydraulics) during its June 2015 meeting in Seoul, South Korea.


I am pleased to report that during its last meeting in Marrakech in October 2017, the IGS Council approved the creation of a new TC on “Stabilization.” The committee will focus on topics such as the base and subbase stabilization of roadways using geosynthetics, as well as ballast and subballast stabilization of railways using geosynthetics. A description of this new Technical Committee’s objectives, an outline of the proposed activities, and a call for TC members can be found on page 10 of this issue of IGS News.


I would like to take this opportunity to remind IGS members that the formation of new IGS Technical Committees is a grassroots process. That is, the most important condition needed to form a new IGS TC is the existence of an active group of professionals interested in advancing the technical knowledge on a specific topic of relevance within the geosynthetics discipline. The key consideration regarding the definition of the topic shall be (1) that the topic clearly belongs to the body of knowledge within the geosynthetics discipline, and (2) the existence of a geographically diverse group of members interested in actively serving the IGS in the production of technical content. Identifying a relevant topic within the geosynthetics discipline without identifying a group of members interested in further developing knowledge on that topic is insufficient justification for the formation of a new TC. Because the topics of TCs will be borne out of the interests of IGS member groups, some are expected to be broad, while others may be particularly narrow. Overlap among some areas to be covered by different TCs is acceptable, but good channels of communication should be established among appropriate TCs to minimize duplication of work and contradictions.


If you are interested in joining any of the IGS Technical Committees, or in forming a new IGS Technical Committee, please contact the following:



For information on the formation of new TCs: Ms. Terry Paulo (

If you are interested in volunteering your time to participate in new, technically rewarding activities, I encourage you to consider joining one of the new TCs of our Society. We look forward to the important technical contributions that will continue being offered by the IGS Technical Committees.
