Stone dust vs sand for laying pavers? Help!

The sand - "concrete sand" is where the interlock takes place - it comes up and fills the joints causing them to lock up. Stone dust will only get hard "under" the pavers and actually hold water, which is another issue. Use concrete sand and only 3/4" under the pavers. Just make sure the base is deep enough and compacted.
