You are fighting a no-win battle. Any seal that you might manage
will be temporary at best. The only proper solution involves
cutting the concrete, creating a stem wall (with footing by code)
and reworking the wall.

I have a bottom plate leaking water underneath it after a rain
and need some
advice. For reasons I won't bother to go into one wall of a barn
sits
directly across the middle of a concrete slab patio. The
exterior is hardie
panel that comes down to 1/2 inch from the slab. A piece of
aluminum L
flashing (4"x6") is sandwiched between the bottom plate 2"x4"
and the
concrete. Before bolting the bottom plate down, several beads of
calk were
laid down between the flashing and slab but the joint leaked
water after a
rain. I then caulked the outside edge with a bead of black
flashing caulk --
the 50 year kind and it still leaks. Any suggestions how I can
make this
water proof? Thanks.

Thanks Dan. I may get to that point but wanted to explore less drastic
action first.
