Site Classification

Site Classification – 2.1.2 – Site Classification based on soil reactivity

All sites are required to be classified. The footing system by the engineer has to be suitable for each and individual site and the only method of achieving this is to assess the site and it to classify it.

The main soil types are sand and clay, with silt as an intermediate type.

The various types of soil are distinguished in an engineering assessment by the size of the particles that constitute the soil such as follows;

  • sand – which comprises material down to 0.075 mm;
  • silt – which includes the range 0.075 mm to 0.002 mm; and
  • clay – which consists of very fine particles smaller than 0.002 mm.
