My deck is approximately 12 ft high. I have a raised bungalow and the deck is attached to the house.
Can u tell me if using concert blocks is safe for a high deck?
The blocks are secured on a large concrete tile and bolted to the tile. The extension is approximately 4ft and has been anchored by 4 concert blocks.
Absolutely not. They are designed for a deck that is very close to the ground. They provide no side to side support and you will never get a permit to use them.
For a deck that high, I would be using 6x6 posts attached to concrete sono tubes set at least 4' in the ground. If this deck has already been built, I would not be using it until the posts have been replaced.
This will not pass inspection, you have to use either big foot or sono tubes & they have to be set to a minimum of four feet in the ground, the post should be 6x6 & bolted with the proper bracketts.
To answer your question, NO it is not safe.
