Fully impregnated poles for a minimum environmental impact: Eucalyptus poles

IRG/WP 05-50224-24

L Nitunga

The classical processes for preservation of wooden poles (vacuum-pressure and Boucherie processes) allow the impregnation of the sapwood only. The new radial-axial injection process has been applied to Eucalyptus poles, and has led to impregnation of both sapwood and heartwood. Further more; preserving product is injected both through the groundline area and through the bott end. This allows the two entrances to benefit from a very high retention of antiseptic.
