Australian Soil Site Classification
Australian soil site classes and classifications are outlined in Table 3.2.4.1 of the National Construction Code. These site classes are intended for use in footing design along with AS 2870 and AS 3600. According to the NCC, if a site is classified as E or P, then reference must be made to AS 2870 for design and construction information, due to the limitations of this part in the NCC.

| Site Class | Description |
|---|---|
| A | Most sand and rock sites with little or no ground movement from moisture changes |
| S | Slightly reactive clay sites with only slight ground movement from moisture changes |
| M | Moderately reactive clay or silt sites which can experience moderate ground movement from moisture changes |
| H | Highly reactive clay sites which can experience high ground movement from moisture changes |
| E | Extremely reactive clay sites which can experience extreme ground movement from moisture changes |
| A to P | Filled sites — see AS 2870 |
| P | Sites which include soft soils, such as soft clay or silt or loose sands; landslip; mine subsidence; collapsing soils; soils subject to erosion; reactive sites subject to abnormal moisture conditions or sites which cannot be classified otherwise |
