Treatment for wooden poles

[JJWalecka]

I was researching Methods of butt treatment for wooden poles

Untreated Beech wood decays in about four years. Beech timber treated decays about fifteen percent in twenty years. Untreated Oak decays approximately ninety percent, in twenty years, and only forty percent when treated.

Why is Beech wood so receptive to butt treatment?

Google "Osmose"

Modern poles are "Penta" poles

I did a quick check of the properties of the two species http://www.woodbin.com/ref/wood/strength_table.htm

and they are similar. my guess is that the properties of beech (grain) allow it to absorb more of the preservative ; however, that's just my guess. Try contacting a forestry or timber association representative (?).

"beech (grain) allow it to absorb more of the preservative" That seemed logical to me also.

Thanks mdshunk

I agree. We use a lot of 'blackjack' poles and we also use Osmose to inspect and treat our poles on a ten year cycle. We used to use almost exclusively CCA (chromated copper arsenic) poles and they really held up (and are still holding up) well. :smile:
