Monitoring of a structure's fissuring framework. The analysis foresees the positioning of the points of measurement on the horse of the lesions monitored, by means of a special resin. After thus marking the distance of zero between the two points with a millesimal deformometer (calibrated on an Invar steel template), we proceed to perform a reading campaign with a cadence of 15 and 30 days, to evaluate the possible displacements of the structure over time.
