I have a nice post digger tool but my dad claims its cheaper and much easier to use metal bars. He has been using 3" (?) metal poles and pounding the ends into a sharp flat surface and then hammering them into the ground.

I have also seen pneumatic fence post drivers (such as http://www.rohrermfg.com/) which would make this work easy with t-bars.

In either case I would need to go 3' deep at least and I want to extend my existing fence, as well as support it (the previous owners did a terrible job and dug only a foot and a half down)

Is there any advantage to using wooden posts with concrete over the other methods?

Thanks

1 Answer 1

If you can get black locust posts, they tend not to rot, or not for a long time. Most other wood posts rot, and rot faster in concrete, IME. Concrete offers no benefit over a properly tamped backfill of soil, in general. Steel posts rust, how fast depends on the climate (well, so does how fast wood rots, for that matter.)

Livestock may be more prone to chew on wooden posts, depending on the stock (swine, I'd suppose, by your username.) Pressure-treated posts can be bad for that reason.

Other than that, the choice comes down to cost, usually.
