Self-Compacting 3/4" stone

 · Re: Self-Compacting 3/4" stone. Many times a set of plans will call for rock to be compacted. This can not happen. Even with sand generally all you do if a vibratory compactor is run on it is to cause it to flow out from under the compactor. Things that have alot of fines like 304, 411 or soil can be compacted.
