Oz-Deck and deck or pier blocks use different construction techniques for building the deck structure. A deck block system requires blocks under every joist with no larger than 5’ spacing, which can result in builders needing twice as many blocks for the same deck than if they used Oz-Deck. Using deck blocks can also be a very time-consuming and tedious method because blocks are heavy, difficult to move, and must be in the perfect location under joists. Oz-Deck may require an extra beam but will offer lateral load strength and substantial vertical up load resistance that is not possible with deck piers. This means that there is no risk of the post becoming dislodged with the support when using Oz-Deck.
