Fustat excavations site suffers from many problems related to its local environment and its building materials. By tracking the site in the proposed time period (23 years), the site underwent many changes in terms of wet and dry cycles, growth of plants, disappearance of some ruins, increase of population and buildings' density. Fired bricks suffer from a weak internal structure, which causes its fragility and easily lost. The bonding mortar is dry and lacks its suitable percentages of improving materials.
