IGS offers introductory geosynthetics videos for students/educators to learn more about/to learn to teach about geosynthetics.
The International Geosynthetics Society (IGS) released online videos aimed at exposing undergraduate civil engineering students to geosynthetics and at providing tools for geotechnical/civil engineering professors to teach about geosynthetics.
An introduction to geosynthetics for students
The IGS offers introductory geosynthetics videos that make up the one-hour “An Introduction to Geosynthetics” lecture, designed to give students an overview of geosynthetics, their different types and their functions. They are part of the IGS’s Educate the Educators Program (EtE). The lecture is delivered by Jorge G. Zornberg, Ph.D., P.E., F.ASCE, from the University of Texas at Austin and former president of the IGS.
Video: What are geosynthetics?
This 11-minute video introduces relevant definitions and provides an overview of the different types and engineering functions of geosynthetics.
Video: Types of geosynthetics
This 22-minute video discusses the main characteristics of the various types of geosynthetics. You’ll learn that geosynthetics are not a single material but a family of materials that includes geotextiles, geomembranes, geogrids, geonets, geosynthetic clay liners and many others.
Video: Functions of geosynthetics
This 32-minute video covers the many engineering functions that different geosynthetics can fulfill. Geosynthetics can achieve many of the functions that have often been accomplished by soil or rock used as construction materials. Identifying the correct function of the geosynthetic in each application is important for defining the properties required in engineering design.
Video: Summary
This 8-minute video is the final component of the “An Introduction to Geosynthetics” lecture and illustrates how the different types and functions of geosynthetics can be integrated into a given application (e.g. a solid waste containment facility or mining related structure). The lecture challenges students to assign the correct function(s) to the different geosynthetic types.

A teaching blueprint for educators
The short videos presented below are a teaching companion to the “An Introduction to Geosynthetics” lecture, which is the initial presentation delivered during a full 16-hour EtE teaching course. The full EtE course provides university professors of geotechnical/civil engineering with the necessary content and pedagogical tools to offer undergraduate civil engineering students exposure to geosynthetics within their current classes.
Video: Foreword to the introductory lecture
This 7-minute presentation elaborates on the target audience for the “An Introduction to Geosynthetics” lecture and the suggested duration. It also discusses an outline of content, with a focus on geo-material properties. The lecture is delivered by Jorge G. Zornberg, Ph.D., P.E., F.ASCE, from the University of Texas at Austin and former president of the IGS.
Video: Experiential learning—integrated panel
This 11-minute video supports planning for an integrated panel to complement the “An Introduction to Geosynthetics” lecture. The topic of geosynthetics is particularly well suited for an experiential learning component in which students see and handle these geo-materials. The lecture is delivered by Maria das Graças A. Gardoni, Ph.D., from the Federal University of Minas Gerais, Brazil.
Video: Experiential learning—geosynthetics lab
This 14-minute video illustrates the dynamics of the proposed experiential learning activity as delivered to participating students. While this activity is particularly well-suited for an in-person lab, the video shows an online version.
