OK until water gets in (which it will) and the post is permanently damp

The only satisfactory long-term protection process for timber is
complete fungal treatment.
Telegraph poles, for instance, are supposed to last at least 20 years
- quite a few have lasted much longer than this. Although numerous
treatment processes have been tried over the decades, the best (and
probably the cheapest) has always been proper creosote, not just
brushed on to the poles, but pressure/vacuum 'applied', hot, so that
it gets right into the cellular core of the pole.

I can see where you are coming from, rain and capillary action from
above or just capillary action from below but that's not quite the
same as the post in direct contact with the soil and the organisiums
in it. This band will also reduce the amount of oxygen available in
that critical length of post.

I doubt very much it's a "cure all", otherwise it would be common
practice to bandage posts at an below the soil boundary, after all
pitch and bitumen have been around for donkies years. I suspect it
may well slow the problem down, less wet, less oxygen but not stop
it.

Telegraph poles also have multiple longitudinal saw cuts around their
perimeter to enable the preservative to penetrate further.

Forgive my ignorance of UK timber treatment since I'm in NZ, where we
have a standard code for treatment, which from memory is:-
H1 is treated against borer and is good for internal framing.
H2 is treated against termites. We don't have a termite problem in NZ.
H3 for above ground and is treatment against rot. I don't imagine the
borer like it either.
H4 for posts in the ground. These seem to last for ever.
H5 for posts in the sea.
I don't recall the rest. Does the UK have a similar scheme?
NZ does have millions of acres of Pinus Radiata which grows very fast
and absorbs the treatments very well.

Can't say I've ever noticed that, at least not above ground. Spiral
marks from them being turned yes but not saw cuts along the length. I
have a feeling such cuts would weaken the pole anyway.

Poles are vacuum treated, ie placed in a container, the air is pumped
out which draws air and some moisture out of the timber. Then the
treatment fluid is introduced followed by return to atmospheric
pressure. The air then pushes the treatment much further into the
timber if not all the way to the core. Unlike normal dipping or
exterior application which really only gets to the top few mm. I
can't see a real reason for requiring cuts.

Didn't notice that when I cut up a discarded telegraph pole last year.
What I did notice however was that the visible discolouration got got
nowhere near the the centre of the pole.

I need another section so I will take a closer look when I return to the
remains.

I've never seen them amongst the hundreds of poles I've had dealings
with.

As a BT cable jointer who has to climb these things regularly, I can say
that some in our area are over 40 years old and still as good as the day
they were installed.

Having worked in conjunction with the PEU (Pole Erection Unit) guys on many
ocassions, I can categorically say that that is utter rubbish - they have no
saw cuts anywhere.

I'm sorry, I got my wires crossed. It was in a marine application,
not for telegraph poles. Too little sleep. ;-)

One other fundamental addition to the poles is the metal 'cap' which
prevents water penetrating the end grain.
many posts start splitting at top due to water getting into end grain ...

Went out decades ago.....

For them as may be interested, BBH are a major supplier of wood poles.

There's always plenty of creosote fumes coming off huge stacks of poles
on the outskirts of Boston

The ones around my parents, which are at least 55 years old and still
look fine, used to have rather ornate giant onion-shaped caps. About
20 years ago, BT came round and took all the caps off. My guess is that
one had fallen off somewhere and they decided the liability was too
high. I imagine they were a very heavy lump of cast iron.
