Building floating deck using deckblocks (free-standing piers)
I'm planning to build a floating deck (18 inches off the ground) and am considering using deck blocks as opposed to set concrete supports. I'll be digging out all the topsoil where these deck blocks will sit.
I was wondering how many inches of screening do I need to put under each deckblock. Also, do I need to lay any type of gravel (ie. 1/2 inch or 3/4 inch gravel) under the screening; and if so, how many inches. Any information or input you could provide would be greatly appreciated. Please note that this is for a house that is one year old (this is our second summer in the house). Not sure I need to take this into consideration, but just thought I would mention it.
Hope to hear from all the DIY RFD'ers who have built decks using this product in the past.
