A non-destructive method for determining at least one of a cover depth and a cross- sectional area of at least a first ferrous rebar that is within a non-magnetic can include the steps of: a) establishing an electromagnetic circuit comprising the first ferrous rebar, an electromagnetic coupler, a first transmitter and a first receiver; b) introducing a first pulsed electromagnetic interrogation signal along the electromagnetic circuit; c) receiving a response electromagnetic signal having first magnitude that is induced in the first ferrous rebar and generating a corresponding response electrical signal; d) determining at least one of the cover depth and the cross-sectional area of the first ferrous rebar based on time information and the voltage information and generate a corresponding first output signal using a response signal processor; e) providing a first user output based on the output signal using a user output module.
