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.

No! You can not use the blocks! It completely un-safe for such situation!

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.

Not at all! For this you should be using big foot concrete footings or a 12" soma tune 4' deep and minimum if 6x6 post and 2x10 beam I would even recommend an 8x8 post, always remember the stronger the better.

Well not quite sure of what you are describing. Are you talking about the post that are holding up the deck ? If you could post a photo that would help to understand.
