Hey everyone, so today we got a 60 by 32 slab with a little 8 by 8 bump out there for a boiler room or 5 and a half inch thick slab with a thickened edge, about 12 inch edge. Got styrofoam down, radiant heat down styrofoam to keep the heat in the slab. Got the thermal brake here on the edge of two inches of styrofoam on the edge for the thermal brake. And then when we pull the form off, these screws here to hold the styrofoam onto the edge of the slab. Two rows of number four re-by here. So this is what we're pouring today. It's about 40 yards, 60 by 32. Hey guys, Mike here. Thanks for stopping by everything about concrete. Mike Chan is all about concrete stuff. We pour all different types of concrete work. Today we're pouring a big insulated house slab. Now the concrete we're pouring for this slab is just a basic 3,500 psi mix. It's got fiber mesh in it, it's got water reducer in it. So we can pour, pretty loose slump. We can pour up to about a seven slump with that water reducer in here with no problem at all. The slab itself is formed with two by 12s. It's got two inches of styrofoam underneath it and up the edges. And the styrofoam is to insulate the slab. It's got radiant heat tubing in it. Those white tubes are pecs tubes that hot water is going to go through when heat the slab. And that's going to end up being the heat and source for the house. So we pour a ton of these slabs in main. I mean a lot of people heat their houses with radiant tubing, radiant heated floors in main. And that's what this one's all about. Now the homeowner is actually the heating and plumbing specialists. And he's here on the job. You might see him in the video a little bit later. But he's the one that did all the, he actually did the form work on this. Got it all prepped, did all the wire, all the tubing. And if you wondered why we're not pulling the wire up is because the wire is in there to hold the tube in place. The hole that nice and straight, keep it from rising up into the slab. The heat and guys, the heat and specialist guys here in main, they like the radiant tubing right at the bottom of the slab. They don't want it in the middle, they don't want it at the top, they want it at the bottom. So that's why we leave it right at the bottom. You guys that want to do it differently, that's perfectly fine. But that's not the way it's done here in main. And we do, we pour radiant heated floors here every single week, literally every week here in main, we do a ton of them. And they're all done this way. So they must be pretty efficient if they're all done this way. Now we're using the MBW Screed Demon power screen today. So you're going to be able to check this out. Battery power, this one works really, really well. It helps screen the floors, makes our job a lot easier. So check this out. A little screen demon action going this morning, battery powered, MBW. You know, quiet that thing here is a bill here. That is literally how quiet that thing is. It barely makes any noise at all. Now, if you've ever run one of these, you've probably run a gas powered one. And you know that the gas powered ones are pretty noisy. This one's a ton different. This one works really, really good on slumps that are, I'd say, between a four slump and a seven slump, probably a five and a six, it works really, really good on. You can see how much effort Luke's putting into that to have to screen that. He's barely any effort at all needed to get that screened. And that board works really good. That shape board that they have works really good on concrete. It doesn't want to sink in the concrete really. I mean, you want to keep some pressure back on that. Keep it moving backwards. You don't want to stop while it's vibrating. But as far as the board goes, that's one of the best ones I've used. I've used a ton of those power screens over the years. This is definitely one of my favorites. There is a link for that down in the description, guys. If you want to check that out, see how much it costs. But that's the first truck. Like I said, in the beginning of the video, this is about a 40-odd slab. So if we're talking a little bit of money here, if we're talking a little bit about making money and how much things cost, 40-odd, when I figure a slab, I figure it at about a hundred and the cost of the concrete at about 140 bucks a yard. So right there, you're talking about 5600 bucks just for the concrete alone. And then when I do the foreman on something like this, if I do the forming and the insulation and the rebarr on the wire, I'm going to be at about two bucks a square foot just to do that. And then if you want to add the styrofoam, the styrofoam's extra. So about two bucks a square foot for the forming, the wire and the rebarr. And then about another 250 to do the styrofoam. And that includes the cost of the styrofoam too. So we're at $4.50 a square foot just to get this thing formed up and ready for concrete. And that doesn't include the gravel work. That's always done separate up here. You never know what type of ground you're going to get into. So it's hard just to put like a flat square foot price on the subgrade level and the gravel level. It's always going to be priced individually and price separately. So as far as the actual formwork and the slabwork, so 450 for the formwork in the styrofoam to get it ready. And then the poor and finish, you know, you can expect to pay somebody like me anyways from a dollar square foot to poor and finished to $2 a square foot. So right in that general range for the lab, just the labour to poor, finish and they saw your expansion joints. So that's going to get you up to, you know, and then when you add the cost of the concrete per square foot, you got about $2.50 to $3 a square foot there. So, you know, you're talking, you're talking about $9 or $10 a square foot just to get a slab like this done. And that's where the gravel grade is really, really good. If you know, if we show up in the sub grades of mass, either we'll try to make it work somehow by raking it out a little bit ourselves, or if it's too bad, we'll just turn around and call the people working for and say, there's Jim right there, the owner on the right. We'll call the owner and say, hey, you got to get that guy back to fix it. Subgrades of mass. It's nowhere's near level. And we show up on a job like this, 60 by 32, to set forms and everything. We want that subgrade to be within about an inch. No way is worse than an inch out of level. And if it is, then, you know, what are you paying the excavator for? You're paying him to get it level. He should have a laser. They shouldn't be that hard to get the dirt within an inch. We're the laser, I don't think. If we got to get our concrete, you know, within an eighth of an inch, let's say over a floor this size, and we're using a laser, then you should be able to get the dirt pretty level, I think. So we're able to screed about 90 some on percent of this slab with that screed demon. And then around the pipes and stuff, we'll use a small hand screed to get around them. Just quicker and faster, just to use something smaller around those. Got down run now. It makes it easy when everybody can run the power screed too, and they all know what they're doing because anybody can just pick it up and go, we don't have to wait for that one person just to do all the screeding. And on my crew, you know, my guys, they don't really care who does what, they just want to get it done. They want to get the concrete in as fast as we can, as accurate as we can, as good as we can. Nobody really cares who's doing what, it's just a matter of, it's just getting done. Yeah, there's that smaller screed, you can see on these around those pipes. That's probably about a six slump we're pouring there today. Three quarter inch rock in that, we never pour anything with the rock larger than three quarter of an inch. Our mixes are all either three eights or three quarter or they're a blend. If we ask for a blend like a 50-50 blend, they'll blend it for us. You can see now Luke's running it. I think I ran it in the beginning, maybe just for a minute, maybe not. I can't remember on this one, but actually doing the puddle in behind the screed is the hard part guys. That's finishing up 60 by 32 slab with an eight by eight. I'm going to get that mag down, get the rest of this bull floated, then it's just sitting here waiting for it to dry so we can power-try it.
