Abstract

La présente invention concerne un matériau géo-synthétique à fonction de capteur destiné à être utilisé dans des structures géo-synthétiques, un procédé de fabrication de ce matériau géo-synthétique et un procédé de mesure des déformations géométriques d'un produit géo-synthétique constitué dudit matériau géo-synthétique à fonction de capteur. Ce matériau géo-synthétique à fonction de capteur comprend un matériau polymère et une charge conductrice de l'électricité. Le matériau polymère et la charge conductrice de l'électricité sont combinés pour donner un matériau géo-synthétique à fonction de capteur. Ledit matériau géo-synthétique présente une concentration prédéfinie de la charge conductrice de l'électricité de façon à conférer à ce matériau géo-synthétique à fonction de capteur une conductivité électrique et une sensibilité aux déformations au sein de la région de percolation ou légèrement au-dessus de celle-ci.
