Quarries sell and price gravel by the ton — order by tons, and add a little extra for spread and compaction.

Estimate only. These figures help you plan how much to buy — they are not engineering or structural advice. Actual needs vary with site conditions, waste, and installation method, so order a little extra and confirm final quantities with your supplier or contractor before you buy or start the job.
