FAQ
- Why 1.5 tonnes per cubic metre?
- It is a typical loose-gravel density. Wet or compacted gravel can be heavier. Ask the supplier if the rate differs.
- What units are the measurements?
- Length, width, and depth are in metres. 50 mm is 0.05 m.
- Does this include compaction?
- No. If the gravel will compact, order a little more than the loose volume.
