I am building a deck right now. The contractor just digged holes, ranges 2 to 5 feet deep, and poured 1 1/2 bag (120lb) of concrete mix in each hole. He is going to put in the post.
So they are still 1.5 foot to 4.5 foot deep above the footing. The posts will sit on the footing, buried with the dirt.
Will the PT posts rot easly? Since they are buied, how can you tell if a post is rotten underneath? The contractor claimed that the post will be good for 20 years. But how can you tell? I would not like to have a lot of people on the deck and then the rotten posts cause a collapse.
Since the posts are do deep, it seems it is really difficult to replace them when they are rotten.
Am I worried too much? The contractor is not willing to pour the more concrete in.
