A hollow cylinder apparatus was used to investigate the inherent anisotropy and membrane penetration of Leighton Buzzard sand test-specimens. The degree of inherent anisotropy was found to be independent
of the mean effective stress but dependent on the initial relative density of the test-specimen. In the vertical-to horizontal
directions, the degree of inherent anisotropy decreases with increasing relative density. A wet-pluviation,
sample preparation technique produces cross-anisotropic test-specimens, with the degree of cross anisotropy independent of the initial relative density. The effects of membrane penetration (expressed in terms of the normalized unit membrane penetration) are found to be independent of the initial relative density and the mean effective stress.
