The bouldery clay in Singapore is a stiff to hard landslide material with randomly distributed sandstone boulders. The soil matrix consists of silty and sandy clay and the shape and the size of the strong sandstone boulders vary. Also, the weathering of the sandstone boulders varies. The depth of the bouldery clay can be up to 120 m below the present level. Bouldery clay is mainly found in and around the central business district of Singapore and many of the high-rise buildings have been constructed on or in this formation.
