All,
More facts to clarify my original post:

1) House sits on a poured cement foundation wall.
2) The desire is to have a single step out to a bluestone patio, instead of a 3
-4 step, from the family room.

3) The idea is to raise the patio, any wood material (sill plate, rim joist,
plywood sheathing) that comes in contact with the patio base, will be prepped
with 30 # felt, then flashed with copper.

4) The base of the patio wil consist of trap rock and stone dust.

5) The patio will be pitched away from the foundation.
6) The house is sided with vinyl.

but my GC told me
since the material uses to raise the grade will be gravel and stone dust,
so,
there is no need to worry about covering properly flashed plywood
sheathing with
this patio base material since it will not retain water. Is he ****ting
me or
what?

Yes, he's wrong. You generally do not want to put wood underground without
an effective moisture barrier. If he can't do a simple thing like this
right how well do you think the rest of the job would be? Get another
contractor, fast.
