Ground line decay is the leading reason for agricultural fence and gate post-failure. Did you know that your posts typically rot in the upper 8-inches of the soil? At the ground line section, the earth is well oxygenated with a higher moisture content and warmer temperatures, making it a breeding ground for nutrients, fungi and decaying organisms.
One of the leading catalysts for decay is the water content of your post. Once above 25%, decay sets in, and it's only a matter of time before that post becomes a costly replacement.
The surface of the timber at the ground line section needs a complete seal to prevent the loss of preservatives and to keep out the causes of decay. Take a look at how Postsaver Pro-Sleeves
could form and air and watertight seal at the ground line section of your posts.
