Using sill gaskets and tar paper on the interior for interior ledgers

So I have ledgers being bolted onto the foundation wall concrete to hang the joists after.
Right now I have tar paper between the ledger and the concrete so that the concrete can breathe.
I was wondering if I would need sill gasket as well on top of the tar paper to prevent moisture transfer.
Thanks!

Richard,
There is no need for the concrete to "breathe." It's important to install a vapor-impermeable layer at this location.
What size are these "ledgers"? Are they 2x10s that will receive joist hangers? Are you using pressure-treated lumber?
