ABSTRACT
Covermeters are widely used for the non-destructive testing of concrete structures to determine if reinforcement bars are adequately covered with concrete and to determine the location of safe spots for drilling for strengthening or repair work.
Recent developments in Covermeter design has seen the addition of data-logging as a key feature for portable Covermeters with software supporting the analysis of data sets generated on the sites of concrete structures.
Covermeters have also made use of intelligent sensor technology to allow a range of interchangeable sensors to be used with a single Covermeter including borehole sensors for finding pre-stressing or post-tensioning tendons deep within the reinforcement structure, sensors for the detection and measurement of stainless steel reinforcement and Half-Cell for the assessment of corrosion conditions.
This paper describes the use and capabilities of such a Covermeter. The analysis, interpretation and presentation of the data will be discussed.
