Topsoil Compaction Formula

Transparent mathematical methodology explained in plain English.

Order Volume = (Area × Depth) / 27 × (1 + Compaction %)

Loose topsoil settles between 10% and 15% after spreading, grading, and initial watering.

Variables Explained:

  • Compaction: Add 10-15% extra volume to reach finished grade.
Real Project Example

Top Dressing a 1,000 sq ft Lawn (1 in depth)

Lawn aeration top dressing calculations.

Sample Project Inputs:
Area: 1,000 sq ft
Depth: 1 inch
Settling Buffer: 15%
Step-by-Step Calculation:
  1. Base volume: 1,000 × (1/12) = 83.3 cu ft = 3.09 cu yd.
  2. With 15% settling: 3.09 × 1.15 = 3.55 cubic yards.
Calculated Answer: Order 3.6 cubic yards of screened topsoil.
