Technical Committee

In 2010, the IGS Council, under the supervision of former IGS Council member Neil Dixon, compiled a guidance document for the establishment of and rules for operating the IGS Technical Committees. Subsequently, proposals were received to form the first three IGS TCs: Soil Reinforcement, Barrier Systems, and Filtration (now part of TC-Hydraulics). These new TCs were approved during the IGS Council Meeting held in Guarujá, Brazil in May 2010.

Participation in the TCs was opened to the IGS membership at large.* As members joined, the committees began work on documenting standards around the world and organizing technical content, such as grouped papers in special sessions or workshops at conferences.

A fourth Technical Committee, TC-Hydraulics, was formed in 2015.

On 8th October 2017 during IGS Council Meeting in Marrakesh new Technical Committee – TC Stabilization was created. This is the 5th Technical Committee of the IGS. Stabilization (or stiffening) involves the use of geosynthetics to develop tensile forces intended to control the deformations within a soil-geosynthetic composite in structures such as roadways. ISO TC221 has identified “stabilization” as an additional geosynthetic function. Others have contended that the actual geosynthetic function is “stiffening,” reserving the term stabilization for applications involving the improvement of the base or subgrade components of roadways. Independent of whether the term stabilization should be used as a function or as an application, it is clear that the term “stabilization” now represents a significant sub-discipline within the broader geosynthetics discipline, with its own theoretical developments, relevant properties, and research.

In 2018, the original TC-Filtration group was combined with TC-Hydraulics to capitalize on crossover research and market development interests.

These four committees–Barrier Systems, Soil Reinforcement, Hydraulics, and Stabilization–have established a strong template for participation and influence within the IGS and in the larger geotechnical engineering community. More committees are expected to be formed.
