There are two spacing requirements for the Dek-Block® pier. The spacing along the support board and the spacing from support board to support board. The maximum spacing between blocks along the support board is 5 ft. from center to center. The spacing of the support board is dependent upon the type of surface/decking material that will be used.
Some building codes in hurricane zones require the use of tie-down kits with the Floating Foundation Deck System. Check with your local building official to determine the requirements in your area.
If you are planning on placing a hot tub on top of your Floating Foundation Deck System, you will need to make a simple modification.
You can hide the front row of Dek-Block® piers by moving the piers and the outside support board 7-1/2" back toward the next row (6" if using 5/4" or composite decking). Add a new outside "facia" board that is the same length as the support board. Use 6" - 2"x6" boards to connect the facia to the support board.
Give your deck character by adding a unique shape or modification to
the deck or decking.
