Concrete anchoring question - your opinion?
 

Hello,

I am building a pool deck and want to place a 15'x18' cabana (four
columns, roof) on top of it. The cabana is held up by 8x8" posts and
has a shingled roof. My question is because the cabana company wants
to have the pool company pour the deck, making it a bit thicker where
the posts will be, and then use concrete anchors to anchor the posts
to the pool deck. The pool company thinks they should place the posts
before they pour the deck so they are set in the concrete instead,
making it sturdier...any opinions?

Thanks,

IMO that would also make them rot faster.

Wood and concrete should not be in contact with each other, that's why there are
so many different fasteners to connect the two while leaving an air space
between. The concrete holds the moisture which then rots the wood.

Get one of these commercial (galvanized preferably) devices that either installs
before or after the pour and then connects to the post.

Are the posts wood?

From the below link (1/4 of the way down)...

[Another serious problem is occurring concerns support posts and footings.
When support post are put into the footing, and even the ground, they are
prone to rot. Even pressure treated posts, including 6x6's may completely
fail within a few years.

The problem occurs when the post is put into the ground, and concrete is
poured around the post. Once the concrete has set, the post has established
a pocket in which water can collect. The water is absorbed into the post
and cannot dry out. In colder climates the water freezes and can crack the
concrete. Additionally, the deck should be bearing on top of the footing
and not in it. Some people are under the misconception that pressure
treated wood will not rot. ]

The cabana people know what is required for their product. The concrete should
be poured with proper sized footings for the posts--deep enough to anchor the L
bolts with some additional rebars in the footing. Then use a proper size post
bracket to anchort the posts the the concrete using the cast in anchors. The
cabana people should have typical detail drawings and recommendations for this
proceedure.

Here are a couple of references for anchor brackets used to bolt wood posts to
concrete:

You should not imbed wood posts (pressure treated or not) in concrete.
Before the posts rot, they will expand and crack the concrete. And then
they will rot. Wood posts should be above (not in) concrete.

Your point? I repeat:

Thank you very much for your answers! I'll ask the pool company to
provide solid footing (18" thick concrete) where the posts will be,
and then I will
let the cabana people anchor on top. Again, THANK YOU!
