Bulk filling materials
Soil is used for example, for the formation of embankments and other areas of landscape 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'. For more information see Cut and fill.
- 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.

Cellular Concrete (Foamed Concrete) has the advantages that it does not require compaction, does settle over time and it can be re-excavated at a later date if necessary. Large amounts can be placed quickly through small openings, so it is often used for emergency void filling, for example, following the appearance of sink holes or an underground tunnel collapse.
