Oz-Deck post supports are perfect for most deck construction projects. The Oz-Deck OD-T4 is an accessory for the T4-850 Oz-Post to allow it to provide load bearing capacity. Oz-Decks are easy to install and can provide the speed to let you finish your decking project in less time with much less work. Oz-Deck utilizes the floating deck building technique. This option in the International Building Code is section 403.1.4.1 Exception 3. Floating deck construction is similar in concept to a concrete patio or a slab foundation on a house. Patios, slab foundations and driveways do not have piers in the ground, they rely on distributing the weight over a large area to prevent them from sinking in the ground. Oz-Deck uses the same principle of spreading the load for the deck over more square inches of earth compared to the alternative method of digging post holes and attaching a ledger to the house. With post holes and ledger construction one side of the deck is attached to the house with a ledger board that is bolted to the home. This requires special attention and advanced carpentry skills to assure that the board is properly attached to the home. Fact: Most deck failures occur because of improper ledger attachment! Oz-Deck is different because there is no ledger board required. The deck simply sits tight to the side of the home but is not actually attached to the home. This is why it is called a “floating deck”. With post holes there is a great deal of pressure exerted on the posts because there are less posts compared to Oz-Deck. This is why it is very important that the piers be installed properly and why many cities require inspections of concrete deck piers. With Oz-Deck, the construction of your deck is much faster and easier. Simply locate the deck plates where your posts are required and drive the Oz-Post through them. Then drop the wood posts into the Oz-Posts, attach the beams, and lay the joists on the beams and finally attach the decking to the joists.

Oz-Deck meets ICC (International Code Council) IRC-2006 (International Residential Code For One- And Two-Family Dwellings 2006) 2006 IRC, R403.1.4.1 exception 3 where it states, ‘decks not supported by a dwelling need not be provided with footings that extend below the frost line.’ The building code clearly has provisions for floating deck systems like Oz-Deck.
