Rising damp in building stones: Numerical and experimental comparison in lecce stone and carparo under controlled microclimatic conditions

Rising damp is considered one of the most widespread and damaging deterioration processes in build-ings, architectural and cultural heritage. A widespread lack of knowledge of this phenomenon has oftenled to inadequate corrective measures with the consequent accelerated masonry deterioration. This workfocuses on the dynamic evaluation of rising damp in two typical and widely used building stones inSouthern Italy (Salento peninsula): Lecce Stone and Carparo. Under controlled and monitored microcli-matic conditions, an experimental campaign has been carried out in laboratory, starting from two drymonolithic blocks. The blocks were periodically wetted, weighed and the height of rising damp measuredin the tested materials. At the end of the campaign, the rising damp behaviour has been derived using thewell-known mathematical model of Christopher Hall and William D. Hoff. Finally, the theoretical modelwas adapted to the case study, modifying the model constants based on the collected experimental data.The results were analysed, and the study showed a good agreement between the numerical and experimental data in both tested materials.
