The International Geosynthetics Society is a non-profit organization dedicated to the scientific and engineering development of geosynthetics and associated technologies. Geosynthetics are synthetic products used in civil engineering, such as fabrics (geotextiles), flexible membranes (geomembranes), etc. The IGS has 1906 individual members and 126 corporate members from 68 countries, as well as 95 student members. There are 31 national or regional chapters of the IGS representing 94% of the membership. The membership includes those who are involved in the teaching, design, manufacture, sale, use or testing of geosynthetics.

The mission of The Geosynthetics Interest Group of South Africa (GIGSA) is to be a non-profit organization dedicated to the scientific and engineering development of geosynthetics and associated technologies in South Africa.

Mission Statement: To advance professional knowledge and improve the practice of civil engineering
In support of SAICE's mission, SAICE strives:
