Soil Classification Symbols

A Sand/Rock, good for foundations, however problems may be encountered wth site excavation

and trenched etc.

S Stable site - generally the lightest footing design is applicable.

M Moderatley Reactive. The majority of clay sites fall into this category.

H Highly reactive clay sites requiring heavier than normal footing designs. Most "Black Soil" areas are at least

a "H" class soil.

E Extremely Reactive clay sites. These are not common, however results in very expensive footings.

P Problem Site. This may be Mine Subsidence, uncontrolled or controlled fill greater than 400mm in depth,

landslips, or soft bearings/collapsing soils and trees near the construction area.

D A sub-classification had been introdiced to indicate deep seated movement. The sub-classification is required

for reactive sites, classes M, H and E and is symbolised by the addition of D. The full classification for these

areas would simply be M-D, H-E or E-D.
