Need to repair a fence. For end post, am planning on attaching it
(4x4 PT) to the edge of a concrete block wall. Dunno if the blox
are filled or not, so would assume not. The fence is a low (~5'
high) "woven-wood" job, made with 1/4" bender boards and 4x4 posts.
Homeowner isn't particularly picky, just wants to make sure their
dog stays out of the neighbor's yard.

The screws (Titen) look suspicious to me, screwing into crumbly
concrete. But the cover of the book shows an actual job using them,
where four large steel eyes, each screwed in with 6 Titens, were
used to lift 20,000 lb. slabs, so I guess they do work.

So what do the expert builders out there say? How would you do this?

For cinder block and brick, outdoors, any ancor will come loose
especially on a gate or fence that vibrates. So i like to epoxy (pc11
2 part) whatever anchor I use as well, then they never come out and
are sealed from water etc. I dust out the hole real good, slather a
lot of epoxy into the hole and on the ancor, then anchor it with the
bolt. I hung an 8 foot cedar driveway gate from 2 epoxied hinges into
brick that never moved in 10 years.

So would you epoxy in bolts (studs or Allthread), or epoxy in the Titen
fasteners? How about if I use epoxy on the Titens? Makes it a lot
easier, as I wouldn't have to somehow prop the bolts up until they set
(they'd be going into the wall horizontally).

I epoxy wherever fastener meets brick and just fill the hole before I
insert, most fasteners have nooks and crannies or threads that let
some epoxy live between the two, the glob of epoxy in the hollow brick/
block behind the fastener also mushrooms out to prevent pull out.
Once that stuff hardens there is no reversing so if the bolt needs to
be removed someday you will have to just grind it off flush with the
wall.
