Dear Colleagues in the ISSMGE,

It is a privilege for us, the current President and Immediate Past-President of the International Geosynthetics Society (IGS), to jointly share with you our thoughts about the many opportunities for collaboration between the ISSMGE and the IGS.

While man-made, geosynthetics belong to the family of “geomaterials.” They are defined as planar products manufactured from polymeric materials, which are used with soil, rock or other geotechnical engineering related material as an integral part of a man-made project, structure, or system. In fact, the advent of geosynthetics has augmented significantly the range of mechanical and hydraulic properties that engineers can now adopt in the design of geotechnical systems. The variety of geomaterials is huge, as illustrated in Figure 1, obtained from a State-of-the-Art Lecture presented in the 17ICSMGE in Alexandria. Note that the geomaterials shown in the last row of this figure illustrates geosynthetic materials. As in the case of soil and rock, the properties of geosynthetics should be properly characterized. It turns out that the characterization of geosynthetic materials has significant similarities with the characterization of soil and rock.
