For clients who are concerned about column rot, decay or insect attack of pressure preservative treated wood columns there are some solutions.
One of them is a product patented in 1994 by Homework Design, Inc., called Plasti-sleeve®.
Now in use in tens of thousands of buildings nationwide, Plasti-sleeves® are the original wood column protection beyond just pressure preservative chemical treatments. The Plasti-sleeve® completely covers the embedded portion of the columns with a molded plastic sleeve. The sleeve has an enclosed bottom and is designed to fit columns cleanly while still offering ventilation. The clean fit means construction methods do not have to be altered to fit other framing members.
We all know plastic will last indefinitely underground.
Plasti-sleeves® are manufactured only from a high quality HDPE plastic. This material has an in-ground decay resistance measured not in years, but in centuries!
Due to what most feel were unfounded concerns regarding CCA pressure treating chemicals, numerous new chemical combinations have entered the marketplace. Based upon their chemical composition, they should perform admirably, however they do not have the decades of successful results like CCA had. Whatever the preservative formulation may be, plastic is as close to a forever solution as possible when it comes to wood column foundations.
The makers of Plasti-sleeve® have also developed an economical version dubbed the “short sleeve”. The short sleeve is available for use on the same popular column dimensions as the Plasti-sleeve®, however it is only 22” long, so it protects the potential decay area only.
Unsure at all of pressure preservative treated wood in the ground? Then Plasti-sleeves® may be the answer for your new pole building.
