The invention relates to a geotextile material that makes it possible to measure the thickness of a layer of backfill covering it. The material performs the functions of a geotextile and makes it possible to measure the level of backfill using equipment designed for this purpose. Such a geotextile can be manufactured by needle-punching synthetic fibres through continuous metal sheets, maintaining a number and dimension of perforations that always allows for detection. Another method would consist in laminating to the geotextile perforated or non-perforated metal sheets that can be detected.

L'invention concerne un matériau géotextile permettant de mesurer l'épaisseur d'une couche de remblayage le recouvrant. Ce matériau remplit les fonctions d'ungéotextile et complémentairement permet la mesure du niveau de remblayage à l'aide d'un équipement conçu à cette fin. Un tel géotextile peut être fabriqué par aiguilletage de fibres synthétiques à travers des feuilles métalliques continues, en maintenant un nombre et des dimensions de perforation permettant toujours la détection. Une autre méthode consisterait à laminer au géotextile des feuilles métalliques perforées ou non pouvant être détectées.
