Different types of building materials were collected from numerous resources reflecting the variations in the depositional environments. Sand, gravels, granite and limestone have been subjected to chemical, physical and mechanical analysis to predict their properties. Sulphate, Chloride and other elements are very essential to determine as hazardous elements affected cement and mortar by chemical reaction. In addition of the shallow groundwater level in the coastal plain, the interaction sea water and carbonate should be considered. Results of geotechnical tests indicated to high quality of these materials which can be used in high-ways and building construction. The geotechnical results mentioned to high concentration of hazardous elements, such as SO4, Cl- and Ca2+ which are directly affected on cement (concrete) and reinforcement. The environmental factors and the distance from the sea are controlling the higher corrosion in the building, whereas, sabkhas have direct effect on foundation and over ground level.
