Deck floating foundations

Could someone give me a review on the floating foundation for decks, such as advertised at deckplans.com? I'm wondering if they are as structurally sound and safe in a northern (Indiana) climate where heaving and high water table are issues. Any reviews or suggestions would be helpful. THANKS

Those blocks are fine for ground level decks but are not structurally sound for raised decks above 2 feet.
Ideally and depending on your soil conditions, they should be placed on a tamped base of gravel instead of just placing on dirt.

Howdy with the frost and local building codes to consider you would be better to dig down 48" and install a paper cement tube and a Simpson strong tie stud anchor plates for your decks posts. Thus installing piers under the posts below the frost line in the soil.
