Different archaeological ruins (walls, floors, and architectural details) have been discovered at Dedan site "Al-Khraibeh" through king Saud University excavation in 2008. Most of these ruins suffer from deterioration factors. Leanings of Dedan walls have been observed toward the west direction, one of these walls was in critical case. Therefore the restoration process should be immediately carried out to save this archaeological wall from collapsing. Documentation, investigation, analysis and diagnosis were carried out in order to determine the wall condition and conservation strategy. To diagnose the current status of the leaning wall same examination and analysis methods were used, optical microscope (OM), polarized microscope (PM), scanning electron microscope (SEM) equipped with (EDS), x-ray diffraction (XRD), and soil classification. Deterioration aspects e.g. flaking, separation and fragmentation have been noticed,clay mortar was used to cement the stone blocks. Dedan soil was classified as silty clay soil (CL-ML). a correct diagnosis always depends on data and correct results, which is the first step of conservation strategy. This paper deal with the restoration and conservation methodology for dismantle and reconstruct the leaning stone wall.
