Self Compacting Stone Ask the Builder

As for other options, I'd simply ask the local gravel companies what other products they may have that are truly self-compacting. Beware of any products containing sand, as the sand requires compaction. It adds lots of friction to the material. You can test this with ease when you shovel sand or dump it. With little effort it will compact.
