Blessed with natural preservatives, Cedar is one of the most decay/rot-resistant and insect-tolerant woods available. Minimal cracking and checking. Cracks will not penetrate the heartwood. According to a University of Maine study initiated to determine the natural durability of various species of commonly used woods, untreated White Cedar possesses a high natural durability, even in underground contact conditions. This finding is proven by the good condition of the surveyor’s corner posts and rail fences still serviceable after 50-60 years or more.
