This study investigates the fundamental soil properties and their correlations in Battambang Province, Cambodia, to better understand subsurface behavior for geotechnical applications. Battambang, located in the northwestern region of the country, is primarily composed of clayey and silty soils that have compacted over time. A total of 33 boreholes were analyzed using field 
Standard Penetration Tests (SPT) and laboratory Unconfined Compression Tests (UCT). Results indicate that undrained shear strength (su) are increase with depth, suggesting that deeper soil layers are denser and more suitable for shallow foundations. Empirical correlations were developed to estimate shear strength from field data, expressed as su = 6.6 N and su = 7.5 N₆₀. These equations provide practical tools for predicting soil strength where limited testing is available. Moreover, a weak correlation was observed between the Plasticity Index (PI) and shear strength, while the Liquidity Index (LI) showed minimal influence. A strong positive relationship was identified between undrained shear strength and Young’s modulus (Ei and E₅₀), indicating that stiffer soils possess higher resistance to deformation. The results highlight the significance of soil depth, moisture content, and compaction in geotechnical design and demonstrate that Battambang soils generally exhibit good bearing capacity for construction purposes.
