I recommend you put roofing or deck coating on the slab. However you
may want to check out Xypex by Tnemec- a waterproofing that relies on
the crystallization within the concrete.

Subject: Concrete Mix for low permeability
Does anyone have any information concerning what to add to
concrete mix or
specify for an overhead slab that is exposed to weather. It is
minimize cracking and reduce permeability. I am designing
around 4000 psi
and the slab has a room under it.
I have never done a slab that had "dry-space" under it.
