I am looking for suggestions on how to attach a 2x4 to a cinder block
wall.
Here is the scenario. The 2x4 will be running horizontally on the
interior of a basement wall below the ground level. It will be
attached flat to the wall similar to a ledger board. The wall is
made of cinder block (not cement block I assume because the property
was built in 1948). The basement was completely gutted down to the
exterior walls and all new walls were framed out with 2x4's for a
complete remodel of a basement level apartment. All of the exterior
walls were framed out with 2x4's with the studs about 1/4-inch away
from the wall and secured at the top and bottom with top plates and
bottom plates.
However, about 15 feet of one exterior wall has a 4-inch PVC sewer
line running along the bottom of the wall about 6 inches above the
floor level. So, the wall above that sewer line cannot be attached to
a bottom plate along the floor because the sewer line is in the way.
What I want to do is run that wall down to a wood "bottom plate" that
is actually attached to the wall instead of to the floor. To do
that, I want to attach a horizontal 2x4 flat to the cinder block wall
with anchor bolts of some sort. Then nail a second 2x4 on top of
that to create the new "bottom plate" for the wall above the sewer
line.
Since the 2x4 will be attached to the wall below the outside ground
level, I was thinking of using some type of rubber or similar strip
to try to isolate the wood from making direct contact with the cinder
block to avoid moisture and termite problems. And, maybe I would use
pressure treated wood for that one 2x4 -- but I'm not sure about that
idea.
So, one question I have is what to use between the wood and the wall
-- rubber, tar paper, or what?
I'd use pressure treated and tar paper.

And, the second question is how to attach the first horizontal 2x4 to
the wall.
Tapcon screws
Any of the various proprietary ,expanding types; eg, Hilti
Lead anchors
Toggle bolts (in core area, not web)
