Abstract
A method of determining the position and condition of reinforcing steel embedded in concrete is described. The method is non-invasive. Electrodes are use to carry out the method by contacting the outer surface of the concrete. The method measures the impedance of selected regions of the concrete by measuring the voltage generated across said selected regions by a current flowing through the concrete.
