To gain a better understanding of how the Green Post™ system works, it is important to understand the
mechanisms of decay. Sections of a post decay at differing rates... First Section - The area 2" above the soil-line to the top of the post is exposed to sunlight and
good air circulation. This is a preferred environment for wood posts to last a long time. The
above-ground wood in this area is exposed to nature's elements and is certainly subject to the
natural weathering processes (simple wood protection methods may be required to maintain
desired appearance).
Second Section - The area 2" above the ground to 6" through 16" below the soil-line is the
most vulnerable area for post decay to occur because high moisture content combined with
available oxygen and soil nutrients is most favorable for biological growth. It is at this
vulnerable soil-line area that a post deteriorates rapidly. Laboratory tests prove that
Green Post™ products eliminate decay because the elements of decay are shielded from
the wood.
Third Section - Required levels of oxygen is not present for biological growth in the area 6"
through 16" below the ground-line to the base of the post. Even though moisture availability
is typically high at this depth, there is not enough food and oxygen to support the presence of
wood destroying organisms.
