Poolboy,

What do you mean by "pavers"? Describe your decking a little better.....you may be able to go ahead with it.

Basically, if you are going to have a "rigid" masonry deck...concrete, pavers with mortar between them, etc. , you will need to backfill with gravel or it will crack.

If you are going to put down stone with sand or dirt in between them, compacting and tamping CAREFULLY will give good results. Tell us a little more about what your decking is going to look like.
