Özet
Floors, walls, domes and ceilings have been decorated with mosaics since the Ancient Period. The technical features and decorative elements of mosaics vary according to time and geography. Some deteriorations occur in mosaics over time, and although these deteriorations are examined separately in each work, generally similar classifications are made to each other. Separations between the construction layers constitute a class of deterioration. As a result of the deterioration of the chemical and crystal structure of the material or the effect of physical factors (earthquake, humidity, landslide, etc.), the bonds between the layers lose their grip. The purpose of this article is to present an assessment on the mortar injection used in the repair works of Hagia Sophia dome mosaics. During the conservation and restoration works in Hagia Sophia between 2002 and 2004, it was determined that there were layer separations in the dome mosaics. Especially the surfaces in the dome, the roof and partially the separated layers of the wall mosaics are temporarily or permanently protected against the possibility of breaking and falling due to gravity. The gaps in these areas were attached to the load-bearing ground with intermittent clamps and an attempt was made to strengthen them by filling them with injection mortar. The mentioned deteriorations were detected with different technical equipments. Endoscopy devices were used in appropriate areas, especially to visualize the cavities formed inside. The stitching method was tried to hold the injection mortar applied to the back of the mosaics. Therefore, it’s shown that it is not always benefical to do injection.
