Compacted Fill = Geometric Volume × (1 + Compaction Shrinkage %)

Loose fill dirt hauled in by dump trucks settles significantly when compacted. A 20% compaction factor ensures you do not run short.

Never dump 3 feet of fill dirt all at once. Compact dirt in maximum 6-inch lifts using a mechanical tamper to prevent future sinkholes.

Loose soil contains 30-50% air pockets; heavy equipment or rain compresses these voids.
