Bulk filling materials
Soil is used for example, for the formation of embankments and other areas of landcape that require fill. It is common to 'cut' soil from the high points of a site and place it in layers in lower areas, in a process known as 'cut and fill'. The soil used for bulk filling must be suitable. Examples of unsuitable soil material for filling includes:
- Soil from swamps, bogs and marshes.
- Perishable material such as peat, logs and stumps.
- Frozen materials.
- Materials having a liquid limit exceeding 80 and/or a plasticity index exceeding 50.
