ℹ️ Understanding Soil Compaction

Soil compaction reduces pore space between particles, increasing density. Typical shrinkage factors:

  • Topsoil: 20-30% volume reduction when compacted
  • Clay: 15-25% volume reduction
  • Sandy soils: 10-20% volume reduction

Frequently Asked Questions

What’s the difference between loose and compacted soil?

Loose soil has more air space between particles, resulting in lower density. Compacted soil has been mechanically compressed, reducing air space and increasing density. The same weight of soil will occupy less volume when compacted.

How accurate are these calculations?

These calculations provide estimates based on average density values. Actual results may vary depending on moisture content, compaction method, and specific soil composition. For critical projects, consult a geotechnical engineer.

Why is soil compaction important?

Proper compaction increases soil stability, reduces settling, improves load-bearing capacity, and prevents water infiltration. It’s crucial for foundations, road bases, and other construction applications.
