I am building a floating deck that is not attached to the house and is 2ft in height. The 4x4 posts are inserted into and resting on top of a concrete decking block. The post is just sitting inside the space provided in the block. In my area, Nevada, this is the only type of concrete deck block they sell. I have seen others where you can attach and secure the post to the block but no luck in my area.
First question, what is stopping any lateral force from pushing the deck over?
FYI, I have over engineered the base of the deck and it is solid. However, as you might guess, because the posts are not secured into the block in any way, I can actually lift the deck up and out of the blocks.
Could this be an issue (lifting the deck out of the blocks) and if so how could I correct it? (without tearing down and starting over)
A few points that might be raised:
- I did not want to dig holes for a concrete footer under each post. (Bad back, lots of work and I have seen many other decks built this way.)
- My assumption is that the fact that these blocks are manufactured this way, without a way to secure the post to the block, they can be used for this purpose.
- I do not live in a high wind, tornado or hurricane area.
