- This study investigates the geotechnical properties of a migmatite - derived soil from southwestern Nigeria for its potential use as barrier in sanitary landfill. The required parameters for soils to be considered as barrier such as grain size distribution, Atterberg consistency limits, maximum dry density (MDD) and the coefficient of permeability were determined. Results obtained show that the hydraulic conductivity is lower than the suggested limit (1 x 10-7cm/s) of the various waste regulatory agencies. In addition, it has adequate basic geotechnical properties, strength and the shrinkage potential upon drying. These properties suggest the potential suitability of the soil as a barrier in containment facility for disposal of waste material.
