A Profometer 5 of Scanlog model from Proceq was used in this research since the Proceq products have the good reputation for its reliability and accuracy in concrete Non-Destructive Testing. The measure with scanning mode was used to measure concrete cover and also monitor the effect of neighbouring bars. Five scans were carried out and five readings were taken for each bar sample. Scanned data were downloaded to a laptop and concrete covers were analysed and recorded. Figure 3 shows an example of the scanned data. After each scan, additional plywood was added on top of the calibration block and the cover measurements were repeated. So, available cover measurement samples in this study were from minimum of 20mm to the maximum of covermeter detectable range (i.e. out of the ability of covermeter for measuring covers with 100mm bar spacing).
