Treated Lumber Decks
Naturally rot-resistant wood is wonderful stuff, but as human pressure on forests increases, woods have become more and more expensive, forcing people to search for more cost effective alternatives. A popular substitute, especially in areas far from cedar and redwood forests, is decking made from less rot-resistant, cheaper softwoods that are pressure-treated with various chemicals that inhibit decay.
The degree of a wood’s rot-resistance depends upon the depth of treatment—wood that is in contact with damp soil needs the deepest treatment.
