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

open access: yesMaderas: Ciencia y Tecnología, 2015
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
