with mortar, arranged irregularly, in the case of stone masonry, or regularly, in the case of bricks or blocks masonry [1, 5]. A good rehabilitation work requires the deepening of the antique buildings and materials knowledge, in order to develop adequate rehabilitation solutions, guarantying safety, functionality and the preservation of the original characteristics [3, 6]. The rehabilitation process is very complex due to the fact that each building, is a singular case, with unique features and pathologies, being of high importance the building inspection and evaluation of its state of preservation, as the study of the composing materials to develop solutions for the existing problems, according to the original characteristics and leading to compatible solutions [3, 7]. The current paper presents a structural masonry walls pathologies evaluation, though techniques, such as, thermometer and humidimeter. The case-study building, built in the 19 th century, in Felgueiras, Portugal, is an example of the built construction of that time, constructed in masonry, with interior wooden partition walls, in the first and roof floors, and wood floor and roof structures as it is shown in Fig. 1.

2. Pathological characterization In order to make an extensive inspection was created a monitoring network to measure the temperature and water content of the walls, using a thermometer and a humidimeter, respectively. 2.1. Masonry walls The masonry walls and wood elements of the case-building have many problems related to humidity due to diverse sources such as: capillarity ascension, precipitation, condensation and infiltration (the water sewer drainage system is
