The condition of historic buildings often conceals hidden threats. One of the key threats is moisture, which can cause irreparable damage when it penetrates the structure. As part of the current thermal imaging survey, special attention is being paid to the portico facing the park and the adjacent underground rooms. The diagnostic campaign has two main objectives: to identify the presence of moisture in the portico's roof structure by inspecting the external facades and to detect possible water accumulation in the masonry on the second underground floor using thermography.
The areas under investigation were:
The investigation was carried out in passive mode (with the masonry in thermal equilibrium).
Passive thermography was performed with the objective of determining the presence of water in the masonry. The elevations were analyzed taking extreme care that there were no irradiated portions of the masonry.
The survey was repeated following a dry period and no areas of active seepage were identified at the time of testing at the porch ceiling.
A beat was also carried out at the technical room on the second basement floor where the presence of water presumably due to capillary rise was detected.
For this inspection, he used a Hikmicro SP60 thermal imaging camera with a 50° wide-angle lens, chosen primarily for its thermal performance provided by the 640x480 pixel sensor with high thermal resolution capable of discriminating a temperature variation of only 0.03°C (NETD 30mK) at room temperature.
Practicality of use in the field is ensured by the large removable and swiveling display and the 180° rotatable optics. In outdoor inspections under strong sunlight, the eyepiece with OLED display (1024x768 pixels) is very practical.
