ABSTRACT
Soft clay soils are commonly found in many parts of the world. Low permeable problematic soils are distributed across the world as expansive soils, dispersive soils, highly compressible clays, marine clays, sensitive clays, quick clays, saline/sodic soils, soft peat and etc. The occurrence of thick deposits of marine clay in the Northwestern part of Peninsular Malaysia, is due to the result of quaternary deposition. The presence of these poor ground condition has posed numerous technical challenges in the implementation of road and expressway projects.
