Many urban buildings in the city of Baladruz suffer from the effect of saline weathering, which is highly active, due to the availability of appropriate conditions for that, such as moisture and rain, high temperatures and evaporation rates, which work together on the activity of salt weathering, after the evaporation of moisture acquired by the walls of the buildings from rain and humidity Atmospheric salts take crystallization in them, then the weathering process begins to appear in the form of whitish spots in the walls of buildings, and develops to become in the form of salt flakes, then the walls begin to peel and push the cement material covering those walls, which is known as (Ficus), It erodes little by little after the crystallization of the salt increases more until large parts of the building materials for those buildings collapse until their walls become deformed, and the process of salt weathering in the walls will not stop as long as the conditions are prepared for that, as it is not limited to peeling the walls and removing the cement materials (Ficus). which not only covers it, but continues its activity, leading to the erosion of the bricks on which those walls were built, especially the brick material that was used in their construction, which was produced in the Baladrooz brick factories, which is a building material that contains a high percentage of salinity due to the fact that the soil from which the bricks are made is very salty And this is what was shown by the results of the analysis of samples of building materials affected by salt weathering, As the results were limited between (25.2-78.3 dsm), which is considered a very high percentage according to the American classification of salinity affected soils, and the walls of many buildings in the city appear distorted due to the activity of the salt weathering phenomenon in them.
