Soil Classification Symbols
Sand/Rock, good for foundations, however problems may be encountered wth site excavation
and trenched etc.
Stable site - generally the lightest footing design is applicable.
Moderatley Reactive. The majority of clay sites fall into this category.
Highly reactive clay sites requiring heavier than normal footing designs. Most "Black Soil" areas are at least
a "H" class soil.
Extremely Reactive clay sites. These are not common, however results in very expensive footings.
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.
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.
