Abstract

A method for monitoring a civil engineering construction including a first metal reinforcement and a reference conductor element. The first metal reinforcement and the reference conductor being separated by dielectric material and each having a first end that is electrically accessible. The method including injecting an incident electrical signal which is applied differentially between the first ends of the first reinforcement and of the reference conductor element collecting reflected signals returning along the conductors in return, and analyzing the reflected signals by comparing them against reference signals in order to determine any potential structural defect in the first reinforcement.
