The crypt was affected by extensive damage caused by rising damp. The bishop of Cremona decided to choose among various methods available in the market the most convenient solution to counter the problem in such a wide complex. The bishop resolved to install Genie, a solution based on the innovative electrophysical dehumidification technology using “multiple frequency impulses”. A study conducted by Luigi Soroldoni (scientific advisor for cultural heritage and professor at “Aldo Galli” Academy in Como) and Umberto Casellato (former Associate Head of Research with IDPA - CNR) demonstrated that the problem was eventually solved. After 12 months from the installation, moisture in the walls fell heavily, by as much as 70% in some cases; after 16 months, the dehumidification process brought the rate of humidity of masonry down to a range between 2% and 4% (physiological rate in masonry).
