OPERATION
SOIL COMPACTION
Trench compaction is usually done in “lifts” – the height or thickness of the loose fill.
The type and consistency of soil being compacted determines the lift. The more
cohesive the soil, the shallower the lift and/or more powerful the compactor must be.
Depending on soil conditions, NPK Compactors are capable of compacting soil to
densities in excess of 95% proctor in lifts as shown.
