Survey of civil engineering works and reinforced earth structures are more and more nec- essary either to the first sign of degradation before failure or to provide the designers and own- ers with some information on the behaviour of their buildings. In this context, the program Geo- detect was launched to develop a warning system based on the optical technology applied in a geosynthetic. The results of the development lead to a reinforcing geosynthetic equipped with optical fibres, offering an accurate measuring system, available for very large areas, easy to install and completed with an analysis device and a warning system which may be adapted to the client's needs. This paper will present the different steps of the validation: tests in laboratory for fine tuning of the system, a full-scale experiment to show the resistance against the damage during installation and the behaviour above a cavity and a finite element modelling.
