The characteristics, composition, and spatial variability of naturally occurring cemented sand deposits in arid lands were examined, by extensive field and laboratory tests at two sites in Kuwait. Field tests included penetration tests, pressuremeter, and plate loading tests. Laboratory tests included basic properties, unconfined compression, triaxial tests, consolidation tests, chemical, and mineral composition. The results indicated very competent non-homogene-ous deposits with variable degrees of cementation, or with cemented and uncemented layers or bands. In general, the strength and the stiffness increased with depth below the ground surface. The disturbance of these soils, and the crushing of the cementation bonds, lead to increased compressibility and decreased strength due to the loss of the cohesion component of strength.
