Does anyone have information on treated lumber footings and foundation. I recently inspected a 20 year old home. According to the original builder the home sits on a gravel base, below the frost line, treated lumber planks and on top of them treated framing covered with marine plywood extended approximately 8 inches above grade. The crawl space shows no sign of deterioration.
Has anyone run into this type of construction? It is suppose to be semi popular in various parts of the country, and last for over a hundred years, which I have a hard time believing.
