Covermeter surveys form part of most concrete condition surveys of buildings or structures.

Moreover, our covermeter surveys can also locate main and secondary reinforcement to determine bar sizes, bar spacing, to determine minimum cover and cover variability across an element.

We mainly use the Elcometer 331 cover meter to determine depth of cover for the precise and non-destructive measurement of concrete cover and rebar diameters and the detection of rebar locations using the eddy current principle with pulse induction as the measuring method.

The use of covermeters is described in British Standard 1881: 204: 1988.
