Soil Classification

- by

BS EN ISO 14688-2, together with BS EN ISO 14688-1, establishes the basic principles for the identification and classification of soils on the basis of those material and mass characteristics most commonly used for soils for engineering purposes. The relevant characteristics may vary and therefore, for particular projects or materials, more detailed subdivisions of the descriptive and classification terms may be appropriate.

The classification principles established in standard permit soils to be grouped into classes of similar composition and geotechnical properties and, with respect to their suitability for geotechnical engineering purposes, such as:

  • Foundations Ground improvements
  • Roads Embankments
  • Dams Drainage systems

BS EN ISO 14688-2 is applicable to natural soil and similar man-made material in situ and redeposited, but it is not a classification of soil by itself.


Identification and description of rock are covered by BS EN ISO 14689-1

BS EN ISO 14688-2:2004 partially supersedes BS 5930:1999, which remains current.
