Geomembranes

Abstract

Since the first applications in the 1960s, geomembranes have become progressively more widely used for the protection of the environment. Some users and consultants are still not familiar with these apparently simple membranes. The aim of this paper is to make geomembranes more widely known, describing first of all the various types and their characteristics. Secondly, examples of applications are given and, a particular case of use for storing effluent from animal husbandry is described in greater detail. Finally, there is an outline of current projects for research, standardisation and certification. These projects, in which Cemagref is actively participating, are essential for understanding and accepting geomembranes.
