I know there are all sorts of preservatives in B&Q etc for painting on
fence posts but isnt there a longer term solution like coating the part
below ground with something to stop water soaking in to the posts, like
a plastic coating. I am basing my enquiry on the basis of thinking most
of the bog standard preservatives are so enviromentally friendly they
probably are not really much good.
Any thoughts or ideas on this.
Leave the post standing in a bucket of old engine oil/paraffin for a
week. Daily coat the post to "ground level" using an old paint brush
When concreting into the ground take the concrete an inch above ground
level and taper it for water run off.
A) Fill base of hole with a load of stones .. compact, fit post then
backfill ... allows water to drain rather collect and be socked up by
end of post
B) buy pots with vac/pressure treated .. not just dipped. Plus a
supplier who does this with high volume of salts.
C) create a small holder ( I used 6" plastic drain pipe) .. and have the
post ends stand in preservative for at least 48 Hrs. They need to be
dry before you put them in to soak.
D) .. do I what I did fit concrete H section posts, and fit wood between
them, paint with Santdtex in colour to match wood - I mixed my own ..
unless you go real close you do not know they are not wood.
They will not rot, and also will not blow or over or work loose
Yes, you don't want wooden posts going into the ground in the first
place, at least, not if you're attaching a large wind sail (a.k.a.
a fence panel) to them.
25 years ago, I used fence post sockets, which hold the post above
the ground. You could get spiked ones you hammer in, or ones to be
concreted in. These have worked extremely well, and the untreated
unpainted timber posts are still rock solid.
Unfortunately, all the fence post sockets I've seen recently are
completely crap in comparison with the ones I bought 25 years ago
(Fensock was the make), so I don't know that this is quite as
viable now. I tried Metapost, and they just don't grip the posts
properly. The Fensock ones have a pair of clamp bolts, and haven't
rusted. The Metapost ones are already rusty in the builder's
In addition to the other options mentioned, you might consider the
concrete post spurs, which you concrete into the ground with a
couple of feet above, and bolt the post to them using coach bolts
through the holes. Again, this would probably work by holding the
posts above the ground.

Something tells me these will be a waste of money, but by then you won't
remember that you used them. I've known people char the bottom of posts
but IME nothing makes much difference. As Dave says the problem lies AT
ground level, not below ground.
At my last house I drilled a 1/4" dia. hole into the posts about 4"
above ground level and angled about 45degrees downwards. Each year I
squirted 'Cuprinol' into each hole to fill it. Each hole was plugged
with a short piece of dowel left protruding by about 1/4". Posts are
still there after 30 years. Don't know if that sort of 'Cuprinol ' is
When I read this, I thought that, somewhere in 'the works', my post had
been edited. Then I realised that I had only saved mine as a draft copy.
It's almost word-for-word. This is what I said:
"To maintain the effectiveness of the preservation, at about 6" above
the ground, drill a (say) 1/2" hole to the centre of the post, and at a
downwards angle of 45 degrees. Fill the hole with preservative (as
above, or creosote/creocote), and put a watertight bung in it. Every so
often, top up the hole."
ISTR posting something similar a few months ago, -or did I only think
about doing so... -getting forgetful in my old age. Anyway the method
does seem to work well if you remember to do it each year.
If you want to use wooden posts, then get decent pressure treated ones
to start with, and avoid cutting them.
I've used http://www.jacksons-fencing.co.uk/treatment-process.aspx before
as they are local but I recoomend them. I know of a couple of their fences
that are over 25 years old, have never been retreated and are still fine.
I assume similar companies are all over the place - no connection with
Jacksons other than being a happy customer! :-)
Yeah, they aren't cheap. Depends what you are after, and when you order.
I found our fence to be reasonable price - compared to local timber yards
for decent wood anyway.
Never looked at their gates, but have heard elsewhere that they are pricy.
I'm sure there are plenty of other places offering similar. I only mentioned
Jacksons as an example I know of :-)
