Hi,
I have to build a small section of wooden fence. I need to plant two
posts into concrete, I've never done this before. Do they go directly
into the concrete? or do you put some kind of mounting hardware in the
concrete then attach them to that? If they go directly into the
concrete, then how many inches should be underground ? thanks
Rule of thumb is 1/3rd the post is in the ground so the total post
length is 4-thirds the height of the fence.

Most who do the concrete around the post thing do just dump it in around
the post. I personally don't much like the "concrete around the post"
way except for a corner post that may really need additional lateral
support and where there isn't ample room for adequate bracing, but
that's me.

One can also simply use quikrete ready-mix to pack the whole and let it
set up w/ ground water as a simple expedient compared to mixing it.
Somewhat easier to retain the position and achieve plumb that way as
don't need bracing while the mix cures.

In frosty area 3 feet depth; however 30 inches seems to work here for
fence not over 4 to 5 feet. It will be interesting to see how our
neighbours six footer stands up after a couple of winters; it's a
fairly windy location with gusts to 90 to 100 kilometres per hour and
higher.

Yeah, in areas where it's wet enough frost heave might be an issue --
we're plenty cold, but dry and sandy enough heaving is so minimal that
for fences never think about it as an issue --

Don't need to tell me about windy locations, though...those kinds of
gusts are pretty routine here as well--in fact we just spent a full two
days of it last weekend w/ no measurable moisture in the front following
to make up for it (as again is so often the case)
