Different building elements with moist areas caused by different sources (infiltrations and rising damp), were analysed: · Infiltrations: (a) classroom wall of the University of Porto – Engineering Faculty; (b) cafeteria ceiling and walls of the University of Porto – Engineering Faculty
Measurements Results Infiltrations - Classroom wall of the University of Porto – Engineering Faculty This study was carried out in a classroom of University of Porto – Engineering Faculty, where it was visible the degradation of the coating caused by the presence of water.
Infiltrations - Cafeteria ceiling and walls of the University of Porto – Engineering Faculty This study was carried out in the cafeteria of University of Porto – Engineering Faculty, where it was visible the degradation of the coating caused by water infiltration through the roof.

One aspect relevant to this development refers to integration of engineering to devise ways that enable the reuse of materials considered as waste, but with great potential of applicability in the building industry itself, through the generation of appropriate technologies and products that can be an alternative to social housing.
The second test for acoustic evaluation was performed in the reverberant chamber in the Acoustic Laboratory of Mechanical Engineering of UFPB, which consists of a room with a volume of 50 m³, built for the testing of acoustic transmission, composed of walls and concrete slabs with 40 cm thick.
Recycled sand and PET bottles were used, which represents a contribution with regard to the issue of sustainability in civil construction.
