ABSTRACT:
The service life of wooden poles such as utility poles is increased by forming the butt end portion thereof with slots that penetrate deeply into the wood, these slots being formed prior to pressure treatment of the wood with preservatives and thus improving the penetration of the preservatives into the wood. After drying, the butt end of the pole is encased in a shell, suitably of polymers, that is bonded to the butt of the pole and presents a barrier to the penetration of fungus or insects, and likewise prevents the passage of liquids which might leach preservative from the pole into the surrounding ground.
