Abstract: A geophysical resistivity measuring device was modified to perform automatic monitoring of historical masonry structures before, during and after grout injection for consolidation purposes. The obtained image is called a geo-electrical tomography. The technique was used to evaluate the deteriorated masonry of the recently partly collapsed Maagdentoren in Zichem,(B). Geo-electric measuring techniques have been adapted from application in geology to be used as a non-destructive technique for the analysis of the masonry structures. It identifies difference of electric resistivity in materials, contributing to identifying layers of different materials or identifying the position of cavities. It is a preliminary investigation technique that can also be used to online monitor treatment as for example the filling effect of grouts.
