A picture(s) of the slab would be most helpful.
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.pschieuer said: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 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.Post and beam under the slab ?
Me too.... I'm just a simple residential guy....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.
lots of support, steel and concrete is one way :whistlingMe too.... I'm just a simple residential guy....
Can anyone with more expertise/experience explain and tell us how that is done...
Thanks.... Just curious
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???lots of support, steel and concrete is one way :whistling
