i worked in a gravel pit for 8 yrs. i have mason sand aka fine wash sand, aka QA 30 aka ???. just tell them what u want it for and they will know. also used under pools.
for 1500 pounds at employee cost was under $3,
I saw one that used corn instead of sand. It was pretty cool actually
Except corn will eventually mold and rot if exposed to the weather.

It was in a finished out barn, so there is that I suppose lol
