Subsequently, one may also ask, how much weight can my deck support?
In short there's no one right answer to “how much can my deck hold?” However, one rule of thumb to keep in mind while answering the question is that the answer commonly is that if a deck is properly designed, it's built to hold 50 lbs. per square foot. It's possible that it could hold much more weight than 50 lbs.
Beside above, are deck blocks a good idea? Deck blocks can work well, but you need to consider a few things. Wait for a couple of years, regardless of the foundation you're using, but especially if you'll be using deck blocks. They're the most susceptible to settling because they have so much soil underneath them.
