Hello members. I'm looking into building a small deck and thinking of using a product called Oz-Post instead post hole digging and cement. The Oz-Post is a heavy duty galvanized tapered post which is sold in different lengths depending on their use. Fences, poles, decks. They get pushed hammered into the ground thru a galvanized plate which is 12" inch square. Has anyone used this system. Any thoughts , concerns or opinions on this product. Oz-Post states you can free float decks with their product and max is up to 8 feet. My deck will only be two feet off ground. I'm going to check building codes in my town.
