Tips for Ordering Gravel

Order 10% extra to account for compaction and settling — gravel reduces in volume when compacted.
For driveways, use two layers: a 4" base of crushed stone, then 2" of finish gravel on top.
Install landscape fabric underneath to suppress weeds while maintaining drainage.
Always ask about compaction factor — crushed stone can compact 15–30% from its loose volume.
