1. A method of inspecting cooling tower fill pack to detect the presence of fouling, the method comprising:

  • providing a ground penetrating radar (GPR) apparatus;

    moving the GPR apparatus relative to a top surface, a bottom surface, or a side surface of the fill pack; and

    processing received GPR data to form a three-dimensional plot of a location and degree of fouling within the fill pack;

    wherein the step of processing the received GPR data to form the three-dimensional plot of the location and degree of fouling within the fill pack includes the step of distinguishing the fill pack from the fouling thereon; and

    ,wherein the GPR apparatus is configurable to identify or recognise and ignore the fill pack itself via programming of appropriate relative densities or dielectric constants for the particular materials of construction of the fill pack.
