Abstract
(EN) A membrane 10 is a geomembrane 10, which takes the form of a non-conductive sheet 11. A conductive layer 13 is printed on to the sheet 11, in this instance in a geometric pattern of a rectangular grid. The lines of the grid 13 are conductive and connected to each other, with non-conductive gaps 15 disposed between the grid lines. Accordingly, a conductive linear network is formed, which has the requisite conductivity for leak detection.
(FR) Cette invention concerne une membrane (10) qui est une géomembrane (10) en forme de feuille non conductrice (11). Une couche conductrice (13) est imprimée sur la feuille (11), en l'occurrence selon un motif géométrique de grille rectangulaire. Les lignes de la grille (13) sont conductrices et connectées l'une à l'autre, avec des espaces non conducteurs (15) disposés entre les lignes de la grille. En conséquence, un réseau linéaire conducteur est formé, qui présente la conductivité requise pour détecter des fuites.
