Ive come across an interesting deck mounting situation. A friend of a friend wants a small deck built for his back porch however his breezeway room is built on some kind of slab which is very uncommon to this area and something ive never seen. I was wondering what my options are for mounting the ledger because i really dont want to do freestanding. ill try to post a pic as soon as i can.

Freestanding looks like it'd be a whole lot better of an option than a ledger, if not your only option.

Piece of mind, legal and in a lot of cases less headache during construction.

You can use some big ol' stainless steel washers as standoffs. Use concrete anchors to bolt the ledger to the wall with the washers between the ledger and the concrete so there's a gap between. Then be sure to flash it correctly and it'll last for years. Or just build it free standing on 6x's.

We don't know how strong that concrete is. Especially adding additional weight to it. You could reinforce the concrete or play it safe and go freestanding.

Touché. Free standing and sleep well at night. And if you're concerned about sway you can still anchor it to the concrete to eliminate that.

Looks to be a prefabbed slab (either 4 or 6") judging from the fact it looks grouted in the corner. Looks to be spanning a garage opening, it is not wise what-so-ever to ask part of that floor system to act as a header and a ledger support.

WAY to many things can go wrong by attaching to that.

Post and beam under the slab ?


J.
We did one similar and needed a w8x18 I-beam underneath to carry the roof, the deck, and the floor over an 11' span. Doesn't look to be any steel under that span and as we all know wood would have to be big.

Thats only about 42 inches off the ground and its a crawlspace underneath. Looks like freestanding it is. I guess i was just a little caught off guard by the suspended concrete pad, not to common in my area.

Thanks Super..... I've certainly seen that from a layman's view in commercial construction..... how do you suppose they did that in the OP's situation...and also why verse conventional???

Pro's and Con's


(I was just asking my son a similar question. He has been contracting/involved with the 15 billion Stephen Ross Hudson Yard (NYC) project..... but he's in a suit job temporarily, and doesn't really have access to the site. He gets to walk it (near it) every once in a while, and tells me the immense size of piers and steel involved.)

I'm not going to learn commercial (too old) but still find those asemblies interesting.....

Best
