A process for the treatment of wooden elements, said process comprising the following steps: conditioning said wooden elements to reduce their moisture content; and a) performing one of the following sequences of steps selected from the group consisting of at least the sequence of steps b 1 ) to b 4 ) or at least the sequence of steps bb 1 ) to bb 2 ); said sequence of step b 1 ) to b 4 ) at least comprising: b 1 ) impregnating the wooden elements obtained from step a) with at least one wood preservative, b 2 ) heating the wooden elements obtained from step b 1 ) at a temperature of at least 51 & deg; C. to fix said wood preservative(s) in said wooden elements, b 3 ) impregnating the wooden elements obtained from step b 2 ) with a solution comprising polymerizable reactive groups, identical or different, that can form a polymer under polymerizing condition, and b 4 ) subjecting the wooden elements obtained from step b 3 ) to polymerizing condition to polymerize said reactive group(s); said sequence of steps bb 1 ) to bb 2 ) at least comprising: bb 1 ) impregnating the wooden elements obtained from step a) with a mixture of at least one wood preservative and polymerizable reactive groups, identical or different, that can form a polymer under polymerizing condition, and bb 1 ) heating the wooden elements obtained from step bb 2 ) at a temperature of at least 51 & deg; C. to fix the wood preservative(s) and to polymerize said reactive groups. The treated wooden elements so obtained and their uses.
