Permeability is an important property of soils. Testing of compacted impervious clays requires better testing techniques than those used in conventional permeameters.GEONOR permeameter solves many problems associated with permeability testing. Saturation of samples is achieved by excerting high pore pressures while the effective pressure may be kept constant. Due to the effects explained by Boyle's law and Henry's Law, the entrapped air in the voids will be dissolved. Aftects of different variables on permeability are analyzed through a set of experiments. The results obtained are quite reliable. The most effective factor came out to be the soil type, followed by water content. A second set of experiments, in which the two important factors of the first-experiment and lime content are run, and the results obtained show that lime content is a significant factor on permeability.
