Evaluation of axial impregnation as an alternative to classical wood vacuum pressure impregnation method

The evolution of laws on the use of biocide products has led to important changes in the field of wood preservation leading to an increasing interest for non "biocidal treatments" like thermal or chemical modifications. While thermal modifications become more and more common on industrial...

In this context, the presented research focuses on a new alternative called axial impregnation, derived from Boucherie process, for impregnation of treatable non durable hardwood species. This process consists of low-pressure impregnation of green wood logs through its lower extremity with treatment solution transiting via natural pathways of vessels. In order to evaluate the feasibility of the method, logs of different hardwood species were impregnated with a copper based preservative solution and the distribution of copper within the wood was determined.
