This study investigates the physical properties of a granite residual soil for its potential use as an isolation barrier for waste materials in subsurface disposal facilities. The results of this investigation show that the soil has hydraulic conductivity lower than the suggested limit (1x10-7 cm/s) of the various waste regulatory agencies. In addition, it has adequate strength for stability, and exhibits small shrinkage potential upon drying. These properties suggest the potential use of the soil as a soil-based isolation barrier for containment of waste materials.
Keywords: residual soil; soil liner; isolation barrier; hydraulic conductivity; volumetric shrinkage strain.
