Frequently asked questions
Why is gravel sold by weight?+
Bulk suppliers commonly load by weight, while projects are measured by volume. Density connects the two and varies by aggregate.
Does the result include compaction?+
Use the waste allowance to cover compaction and an uneven base. Ask the supplier for a recommended compaction factor for large jobs.
