Building a Free Floating Deck

Bob visits a job site where a deck is being added onto a house. Due to flood plain regulations, the deck cannot be attached to the house, it has to be free floating. Bob joins Al and Steve that are installing post brackets into the concrete with stub cut nails. Next come the short posts. They are using joist hangers on the rim or outer joist to speed up installation time. Then the pressure-treated floor joists are installed, making sure the crown or sag of the board is up. Next comes a tongue-and-groove floor material made out of Southern yellow pine.

" Get a flood plain regulations the deck cannot be attached to the existing house as to be free floating almost like a giant. Twelve by fifteen foot coffee table if you will sitting on these little legs that are right onto the old concrete slab that was after off a carport originally let's go to the other side of the area. See how we're attaching this to the slap. Hi Al -- now what you're using aren't really. Close brackets right are made out galvanized metal keep as pick up exactly and you can just fasten them right into the concrete with stuff. What do you think. Their step cut nail a stub cut -- and when you really hammer these into the cement in the old concrete in the you can't rip. Out. All right with a both based bracket -- that for the time. And recently and I'm ready to position our boats and they really are short stubby little legs for this deck and out he's already got started over here without. If you joist hanger right which are the way to go when you're building a deck around handing out the pieces together to protect one -- the other. Here we got -- and I. And these metal joist -- sister spent just there are articulate nonsense. And the all right with a joist hangers all in place are really ready to assemble all the pieces. And will nail them afterwards right that's okay. Now we've got is in the middle here because occurred wouldn't shift. Right and this is just doubled up and raised so that all of these along joists that are going all the way across the whole fifteen feet. This'll take this spring out of spring out of the exact deck. These are all pressure treated joists and of course the important thing to keep in mind is that when you go to -- lumber yard you pick the best ones that you can. And you make sure that they're nice and straight. All dimensional lumber has a little bit about what we call -- crown to it so that it's not perfectly straight it might sag in one direction or the other and when you put it in place you want to make sure that the -- faces down in the crown basis -- That way when the load on the floor is adjusting it it'll flatten out even. And these dog though. Well they go sixteen inches on center. Well looks like you measure twice and you only cut once that I think that's -- good fit. All right and then the bad and are we ready to nail. After -- we put this last one in here. To take notes that in -- Bring it up okay now we're -- this right now like we're -- obviously well you know right through the like that and the joist hangers else. We're also out. Glue on each side of the joints tank. And the good thing to do. When you got a team of carpenters like these guys this detail up against it out. Does that way to hold that won't be probably all over the place. Pauses looking good. You don't usually when you're building a deck use in decking material and you space at about a quarter -- an -- of an -- apart -- that Rainwater -- right -- But we're not doing that we're putting down a tongue in groove floor which will mean it'll be totally solid but it together the reason for that is that. It's a screen porch and we're in Florida and a lot of bugs could come in right through the cracks of your decking material that you did it otherwise. You might also ask why are we or into the boards in this direction and that's so that all of these joints where the tongues meet the growth from our. Going in the same direction as the pitch of the floor we've got a two inch pitch from that wall to the outside edge of the Rainwater can run right off the won't get that much Rainwater end here lessons of hurricane. Are you guys almost ready to to a close look at this I think we need to call it looked pretty close to color that I have a serial -- He picked it up -- here. This is southern yellow behind but you do tend to get problems like that. It's a very hard wood. The announcement -- The tongue is damaged. So we want to get rid of that. And I think the rest of -- pretty pretty decent. Now but as we go yeah we thought we we -- on record and it's got a little bit of your private jet all right let's get started how do you get started. We're if you -- tongue and groove. And we have to print that that job of this group get rid of the group right through them we let this overhang unhappy if we're with a -- Just follow it right this deck right up there. It's. OK now that has been written plane were ready to put this one down right -- right. How much of an overhang we believe we're going to overhang about evidence right after -- boatmen's. And that's what kind of a nail that we were going to use an incident happened galvanized finished -- we have the face nailed it right it's. And it's nice to have a harness when you use in the southern yellow pine that's hard stuff."

" The rest of them. Use a different kind of nailed yeah we're gonna use this. Down nailer Detroit nailed didn't -- the same kind of tool has been around forever for putting down hardwood floors inside the house right and dust that draws modernized and tied it puts in a -- right in here. -- that's ago. It was a nail it has a flat profile and really look -- the right through untimely and that's how it works okay."

" Now the beauty of this tool is that as you. Kennedy each time Natalie driving the nails yeah you're also making sure that the the two boards get real close together as close as you can get. Tying into the group. Favorite -- yes or no but I'm going right over again. Looks good because now what about all the butt ends over here that have to be trim what you see this the end of the deck with Steve got a line struck very blue chalk line chalk line. Get a straight edge here so what he put the sod down it make -- perfect straight that great let's watch him do okay."
