Patented by Charles A. Seely, this method achieves treatment method by immersing seasoned Wooden in successive baths of cold and hot preservatives. Through the hot baths, the air expands inside the timbers. In the event the timbers are transformed into the chilly bath (the preservative can be transformed) a partial vacuum is produced within the lumen with the cells, leading to the preservative to become drawn in the Wooden.

Once these chemicals have leached from your Wooden, they are likely to bind to soil particles, specifically in soils with clay or soils which have been additional alkaline than neutral. In the United States the US Client Solution Safety Fee issued a report in 2002 stating that exposure to arsenic from immediate human contact with CCA treated Wooden may be larger than was Beforehand assumed.
