Reply to comment by SirMaxPowers in What is the max joist span for a deck with deck blocks? by OrangeYouGlad100

Thanks for the suggestions! Unfortunately, I already bought like 20 deck blocks that have a space for a single 2x and therefore can't fit a double beam (this kind https://www.lowes.com/pd/Common-7-in-x-11-in-x-11-in-Actual-7-125-in-x-10-375-in-x-10-375-in-Concrete-Deck-Block/50113084 ). I suppose I could return them all.

Alternatively, could it make sense to use 3 beams like you suggested, but put the blocks under joists instead of beams like in my picture? I got that idea from these plans:

What's the load/ weight your putting on this? Usually the load is supported by beams running 90 degrees to the joists.. I can't speak to this plan, I've never built one like this but it doesn't mean it's wrong..

Unless your installing on concrete you'll want to make sure all 20 blocks are level and even with each other. That can be a pain but depending on skill and terrain. But if you're going for a low profile look than this might be better than buying and burying adjustable pierpads. Good luck!

Thanks. Aside from the weight of the deck itself, it will only need to support a few deck chairs and a few adults. And yes, it will be low profile. The joists will be just an inch off the ground and the surface of the deck around 8 inches high.

Gotcha. Make sure you use treated lumber, not much ventilation under there. Good luck.
