Impregnation

Impregnation

Wood impregnation involves treatment with chemical substances to protect the wood from decay, parasites, changes of colour and to prolong its service life. Due to the effect of biocidal substances existing in the antiseptics, the environment of wood destroyers is stopped. After the impregnation of the wood, its resistance to heat increases, and moreover, the structure of the wood becomes smoother and its appearance is more attractive.

Deep vacuum-pressure impregnation of wood

Deep vacuum-pressure impregnation of the wood extends the service life of the wood (with a warranty period of up to 25 years), as the impregnation liquid penetrates through the overall depth and the wood becomes exceptionally resistant to moisture, sun rays, fungi, decay, bacteria and even to termites. This is indispensable for wood when it is used outside and is constantly affected by humidity. We use deep vacuum-pressure impregnation of wood, which is currently the most efficient type of impregnation technology.

Stages of deep vacuum-pressure impregnation of wood

Wood is loaded into the impregnation cylinder (autoclave). In the cylinder, air is vacuumed from the wood cells.
A selected impregnate is placed into the cylinder.
Hydraulic pressure is then switched on, forcing the solution to penetrate into the wood cells.
A final vacuum removes any excess liquid and returns this back to the storage container.
Due to the weak pressure inside the wood, a small amount of the liquid will ooze to the surface and evaporate. The impregnated wood is stored for some time until it is fully dried.
