Postsaver protective sleeves are a two-layer system: a durable polyethylene outer layer lined with a meltable bitumen inner sealant. When heat is applied, the inner sealant melts while the outer layer shrinks onto the post's surface, forming an air- and water-tight seal that blocks every factor rot needs to take hold.
The Postsaver sleeve is fitted to the post in the ground-line zone - exactly where water, microorganisms and thermal fluctuations do the most damage to the timber.
A post's service life with this product is significantly longer. Recommended for pine posts that are dried and impregnated to Use Class 4.
