This paper presents the geotechnical investigation and characterization of intact rocks in Gebel El Ramliya -Akheider, located in the Cairo-Suez district, Egypt. The study area represents a strategic economic zone due to industrialization and urbanization. Hence, four rock units were investigated in this study. Along with this, Destructive and non-destructive tests were conducted to determine the geological and geotechnical properties of the intact rocks in the study area. The results showed significant variability in the geological and geotechnical properties of the intact rocks in the study area. As a result, the Middle Eocene rocks were classified as having medium strength and stiffness, indicating their suitability for geotechnical purposes with further assessment. On the other hand, the other rock units were found to have low to very low strength and low to medium stiffness, highlighting their limited geotechnical potential and the need for caution during engineering activities. These findings provide preliminary information about the geotechnical properties of different rock units, which can be useful for geotechnical and construction projects.
