- Using a density meant for water or soil instead of gravel.
- Ordering exact calculated tonnes with no allowance for compaction.
Frequently asked questions
What density should I use?
1.5 tonnes per m³ is a common default for crushed gravel. Lighter decorative stone or mulch may need a lower density.
Can I use inches for depth?
Yes. Choose inches, centimeters, feet, or meters for depth independently of length/width units.
