A combination of vacuum and pressure push the chemicals onto and into the wood. Not only does this protect the wood from climate changes, but also keeps away fungal decay and insects like termites.
Normally, poles made of sapwood, such as the Southern pine, take pressure treatment better than those of heartwood. The structure of the wood layers is what allows for easier absorption. Heartwood trees, like the Douglas Fir, are heartier. However, the chemical composition of the pressure treatment needs to be changed to allow for proper distribution.
