Excavated Soil Volume [Free Calculator Tool]

To use a bulking factor number you have to multiply the bulking factor number by the excavated volume size. For instance, a bulking factor for Clay and Gravel is typically 1.15. If your excavation was 15 m3. Your volume size would be 1.15 x 15 = 17.25 m3. You must consider the bulking factor of the material you are digging to ensure you ...

Bulk Density - Measurement | Fact Sheets | soilquality.org.au

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).
