Voids underlying engineering re-enforced ground floor could be hazardous and may hinder proposed project objectives, if not adequately detected. Ground penetration radar is non-penetrative and non-destructive technique that is used successfully in this study to identify these cavities. The short radar pulses from antenna sources within microwave band of radio spectrum adequately images the subsurface to appreciable depth of interest (<1m) below re-enforce concrete floor. This technique is recommended for void detection in engineering work in very sensitive areas like gas areas like gas flow station because of its safe operation.
