Abstract: A methodology was developed to clean geo-electrical measurements on masonry structures from geometrical and other disturbing factors such as moisture and salts.
Only relevant information about the internal structural situation of the masonry remains.
This paper shows the practical applicability of cement grout consolidation as well as its control by means of resistivity measurements.
A plain brickwork test wallet is used in the experiment.
Controlled cracking is made in the initially sound wallet and repair is done by cement grout injection.
Resistivity values are measured in the sound, cracked and repaired situation.
Relative difference mapping of these resistivity measurements shows a clear picture of the internal situation in the masonry and can serve as a basis for design decisions.
