In this paper, we present an integrated approach, for assessing the condition of an ancient Roman building, affected by rising damp and cracking phenomena. The combination of high-resolution geophysical methods, such as seismic and electrical tomography, with biological information, allowed a more detailed evaluation of the state of conservation of the masonry building. A preliminary three-dimensional electrical survey was conducted to detect the existing building foundations and to determine the variation of the resistivity in the ground. Then, electrical and seismic tomography investigations were carried out on an inner wall of opus caementicium, subjected to rising damp effects and cracks. This approach was adopted to obtain a high-resolution image of the wall, which allowed to identify the inner mortar and the outer brick component from resistivity and velocity contrasts. Furthermore, the geophysical results revealed evidence of wall fractures (indicated by low velocity and high resistivity values) and a significant volume where rising of damp was taking place (resulting in a low resistivity zone). Biological analyses validated the geophysical model: in fact, the biological proliferation occurred up to a height of 0.75 m, where the interface between high and low resistivity values was recovered. This approach can be employed to reconstruct a three-dimensional model of masonry structures in order to plan recovery actions.

“…In a previous work, Cardarelli et al . () established the hydro‐geological setting of the archaeological site (point (i) of the proposed procedure) in order to assess the causes of the rising damp in masonry building materials. Through 2D geo‐electrical investigations, they detected a freshwater aquifer at a depth of 2.5 m (0 m a.s.l.…”

“…Soaked masonries often show serious conservation issues. The phenomenon and the resulting decay have been extensively studied [1][2][3][4], as well as possible remediation methods [5,6], both from the theoretical point of view [7][8][9][10][11], and on several real case studies all over the world [2,[12][13][14][15][16][17].…”

“…For this reason, it should be limited to the most in the case of ancient and historical masonries. Next to these methods, non-destructive moisture analyses are also frequently used: IR thermography, resistive methods, dielectric methods, microwave instruments [4,14,20,21]. Despite their sustainability, the non-destructive techniques present some disadvantages such as: the semi-quantitative qualitative nature of the results; the relative representativeness of the obtained data (often related only to the surface); the need of calibration with data coming from destructive sampling; and the necessity of an adequate data processing [22][23][24].…”

A B S T R A C TConsidering several real case studies, moisture distribution due to rising damp in Venetian brick masonries is discussed and empirical models are developed. Moisture content and soluble salt data of 25 historical buildings in Venice are analysed. Data are scrutinized using statistical methods, obtaining contour plots and estimating the validity of linear and non-linear models. The models confirm that masonries are usually soaked with water till 120-150 cm over sea level, while the evaporation zone ranges in height from 200 cm to 350 cm. In the perpendicular section, moisture distribution depends on several contingent factors such as, among them, the proximity and the exposition of the external façades to the water action.

“…Electrical Resistivity Tomography (ERT) is used for evaluating the conditions of ancient masonry walls and structures [Sass and Viles 2006, Mol and Preston 2010, Tsourlos and Tsokas 2011, Cardarelli et al 2016. Ensuring the good coupling between surface and electrodes is also a major limit of this technique, whereas only non-invasive electrodes can be employed (as for the archaeological purposes).…”
