Nowadays there are many diagnostic methods for the detection of different defects in building structures. Destructive methods, which do not enable purposeful redevelopment action or a potential cause prediction of the defect without damage to the structure, are mostly used. Lock-in thermography is based on the modulation of the controlled heat flow, which impact on the diagnosed object. Heat (usually sinusoidal) wave penetrates inside the element and in the place of environmental change, ie. anomalies / deviations in the structure of the material of the tested object are reflected back to the surface. The paper focuses on the possibility of using lock-in thermography in the detection of various defects in building structures.

Article deals with the issue of mold in masonry structures. Attention was focused on the critical detail at expansion joint. Variants of solved detail are focused on the process of surface temperatures in the structure. This detail needs to be solved because of revitalization of the structure. Isotherms of the critical inner surface temperature and dew point temperature were used for the evaluation of the variants.

At present there are many diagnostic methods for the detection of different defects in building structures. Destructive methods, which do not enable purposeful redevelopment action or a potential cause prediction of the defect without damage to the structure, are mostly used. Pulsed thermography consists in rapid (pulse) external or internal heating of the element and the subsequent evaluation of the temperature field on the surface of the element with the thermal imaging camera. A pulse method is divided into the reflective and passes according to the arrangement of the heating source, object and thermal imaging camera. The surface temperature is changing rapidly, driven by pulse stimulation due to scattering of thermal wave, radiation and convection. The paper focuses on the possibility of using pulsed thermography in the detection of various defects in building constructions.
