It was nice to see your wife and daughter on today’s video. You are really getting it done, amazing! It was in the 90’s in GA today, I love the cooler weather. I am afraid it’s going to be a HOT 🥵 summer for us.
I'm kinda wondering if its ever going to stop raining this year. Last year hardly any rain, this year every other day. :)
Great video. Great to see the family working together
It is nice when they're out there. Most of the time they're at school though. At least for the next few weeks, then they can help more. :)
Thanks for the video! Great job! 😊
You're welcome. Thanks for watching. :)
Impressive!
thanks! :)
Nice clean job
Thanks. :)
Nice video, you got a lot done this day
Some days are definitely better than others. Its getting there though. :)
Oops. Insulation goes under the water/vapor barrier unless you are building an ice rink or refrigerator.
Thanks for watching. :)
0:53 kitty!
A special appearance by one of our cats. Thanks for watching. :)
Nice to see the excellent progress, supervised by cat, so everything should be perfect.
She didn't want to stop inspecting everything under the vapor barrier. Had to get her out a few times so I didn't accidentally step on her. Pesky cat. :)
@@KoalityofLife Yes, they can be, but as her servant you / we cant really complain.
@@skizzysmith Fully aware of my servitude, she requests (sits there and stares at you, if you take to long starts to yell at you) to be picked up and placed on the counter at the location of her food bowl so that she can eat. Little princess. lol :)
cat at 1min. so um what you gonna do with this empty box ?? LOL
Leave an empty box around for more than a min and she will be in it taking a nap. lol :)
Kitty "helping." :)
The cat is always inspecting my work. Thanks for watching. :)
now would be the time to run your pex for radiant heating. even if not something do later it is nice to have the options to do so. but if was doing a wood stove or outdoor wood burner it would be a nice way to trap and store heat :) and only cost maybe 200$ to do in pex materials.
We looked into radiant heat in the floors but found that it isn't all that cost effective to run a gas system and if yo have a boiler room yo have to keep it burning in the winter or it will freeze, basically cant leave for a few days without draining the system. Went ahead and put the extra insulation under the slab to help with the winter months. Less to worry about. Trying to keep it simple. :)
@@KoalityofLife you put a antifreeze solution in it so it cant freeze :) and so it changes the boiling rate so it cant build pressure.
@@StevesDIYProjects7 True enough, if you want to invest in a lot of antifreeze. The other thing I found out talking to a few contractors is that you technically need a thicker pour if you put radiant heat in because you are supposed to have 2 inches of concrete below the bottom of anything like rebar or radiant heat and 2 inches above the top of anything, this makes your concrete minimum 5 inch thick. If you don't pour thicker its like cutting an expansion joint at every piece of rebar or pex tubing. The concrete is to thin and over time with settling you get a lot of cracks. Most floors are covered with some type of flooring so the cracks never get seen. Everything I have read about it makes me skeptical about it, I want our house to last as long as possible. No gimmicks, just wood walls, big beams and a wood burning stove. Not trying to be a jerk. :)
@@KoalityofLife nah all good. i love wood heat my self.
or electric back up.
@@KoalityofLife Interesting. You just made me reconsider some of my plans. I am going to think more on this.
What did you use for forms....they are GREAT
I made forms out of plywood and 2x4's. :)
They have those cordless tools that ty wire the rebar it would save you a lot of time if you could rent one for a day
Would have saved a bit of time, but we're pretty rural out here and not a lot of tool rental places around. :) Thanks for watching :)
What is the vehicle in the background, or perhaps more aptly, what is the body and what chassis is it sitting on? Any videos or forum threads on it? Looks interesting! :-)
I'm going to take a shot in the dark and assume you're talking about the "68 elCamino that's sitting on a 2001 Tahoe 4x4 rolling chassis. Lots of work there but not many videos on it, I built that car before I was really into UA-cam but there are a few videos about it on our channel. :)
@@KoalityofLife Nice, thank you! Looks pretty sweet - I will search and have a watch :-)
@@fredio54 I still need to finish it. After the shop gets built I will bring it back in and work on the interior and give it a show. :)
Iceberg waiting to happen. Plastic should have been on top of insulation.
The plastic is a vapor barrier, the insulation is there to keep the cold out, the order in which you put them down depends on who you talk to. Thanks for watching. :)
Did you have any trouble with the foam floating when you poured the slab?
Nope. It all held in place just fine. Thanks for watching. :)
👍👍👍👍👍👍👍
Thank you :)
Just curios, are the vapor barrier and insulation standard or required in a monolithic slab foundation?
It depends on your county. A vapor barrier is a good thing to put in because it restricts naturally occurring gases from coming up into your building. Insulation is standard in colder climates but a good thing to put under and around any slab foundation to lower heating and cooling bills. :)
ok, I'm getting a home built in west Texas and it looks like builder is not putting vapor barrier or insulation, though we are mostly dry throughout the year. I have to ask and see. Thank you.
@@martinvilla5057 You're very welcome. I would at least have a vapor barrier under the slab. Hope your home build goes fast. :)
My cat looks just like that one in this clip
Must be a good looking cat. :)
Have you had issues with putting the insulation above the vapor barrier since that will only trap water? Just curious.
Ummm, not sure what the question is but the vapor barrier will trap water below the insulation, the water in the concrete will evaporate out the top of the concrete as it cures. If you are worried about the insulation molding, (I've heard this a few times) the insulation is mold and mildew resistant. And no, we have not had any issues with the way we built it. There are different ideas and opinions about the proper way to pour a concrete slab, so many in fact, they all contradict each other. Not trying to be an arse, hope this answers your question. :)
@@KoalityofLife No worries, we did a radian slab on our offgrid home and in my research found that the insulation needed to go under the plastic. Glad it worked out for you.
@@Off-Grid :)
@@KoalityofLife The slab is fairly high so the poly probably isn't trapping water. It you put the insulation above the poly, the groundwater can get trap in the insulation. This causes thermal drift of the insulation (it's insulating value goes down). Most people put the poly above the insulation to avoid the issue. Once XPS gets wet, it has a harder time releasing the water than EPS. However, EPS can also soak up water more easily.
My preference for a small slab like this is to add more rebar than to do cuts. If the slab is structural, you can't do cuts. 15' between cuts is okay for a typical slab-on-grade.
Thanks for the information and @@yodaiam1000 Thanks for the information and thanks for watching. :)
While researching for an upcoming project this popped up. Toni and I were just talking about you. Hope to see you at a UA-cam meeting this summer. Take care. @breakingfreeoffgrid
I miss going to the meetings and seeing all our friends. Hard to travel in the winter though, hoping fuel prices go down in the near future so I can make it up there soon. Hope all is well with you two. :)
Kitty is dying to jump in there
She's always into everything. lol :)
That insulation is 50 bucks a sheet now.
The price of everything is out of control now. Thanks for watching. :)
should have used foamular 400 under that slab - it has a higher compressive strength.
Yeah, thanks for watching. :)
Owens Corning web site lists the different versions of Foamular - and the purpose for each version. Have a nice day.
@@davidbalicki3567 Thank you, you too. :)
If u leave that cat under and finish floor level is cat's body heat be enough to passively maintain pleasent floor temperature?? :-)
Ummm. I don't think so. lol :)
Find a big,FAT cat. That'll do it.
Is the 6mil barrier think enough for that slab?
The 6mil plastic is a vapor barrier. Not sure what you mean by thick enough. :)
@@KoalityofLife Reason I ask is because I usually see 10 mil as the minimal thickness, so I was wondering if 6 mil will be enough
@@StrappingYoungComrad As far as what I was told 6 mil was standard around my area. The main thing is to make sure whatever vapor barrier you put down does not rip or get any holes in it. :)
@@KoalityofLife Thank you for your reply.
So where is the pour?
I have a time lapse video that shows the pour. :)
Usually vapor barrier goes over the insulation. Curious why its under insulation in this case.
I don't know why the county had me put it under the insulation. I'm not a contractor and I have never dealt with a vapor barrier before this so I really don't know why it would matter. I just know it's there to prevent gasses from coming up into your house. :)
Typically the vapor barrier goes over the insulation just to ensure concrete doesnt get under the foam board and float, which I guess is easier to do with the foam rather than the vapor barrier.
So why would you not just use wire mesh instead of all that rebar on the flat surface?
I would have used a wire mesh on the surface area but the house plans we turned in to the county were engineered and called for #4 rebar throughout the slab so I was stuck using rebar. :)
@@KoalityofLife Sounds legit.
would the U for Ground not eventually cause the rebar to rust?
A ufer ground is a piece of rebar that is connected to the grid of rebar in the foundation of the building. None of that rebar should be exposed to the ground where it could rust. With that being said, concrete has water in it until it dries so the rebar will start to rust as soon as the concrete hits it but it would take over a hundred years for it to rust through. I'm not saying that I'm not trying to build a house that will last but if it is still standing in a hundred years I would be impressed. As for the piece of rebar sticking out of the ground to attach the ground to, it hasn't started to rust yet. :)
@@KoalityofLife So is the rebar directly connected to the grounding rod or do they connect through copper wire? Sorry I'm just a bit confused, it's the first time I've ever heard of grounding the rebar. Interesting. Thanks for your comment, just started watching the channel, going to enjoy following your build. Cheers.
@@DigitalAwareness It really depends on the build. In our build we have a 400 amp main separate from the house. The 400 amp main has 2 grounding rods pounded into the ground that it is connected to via a #4 copper wire. The house has a 200 amp panel that is grounded to the ufer ground via a #4 copper wire but in the house the neutral and the ground are separate and we have a ground #4 copper wire also going to the 400 amp panel outside. I was told that this was called "floating the ground". There are no grounding rods pounded into the ground under or around the house. I don't know much more about the grounding system as I am not an electrician but I learn more every day. :)
The cat match with the plastic
Shes a very curious cat for sure. Thanks for watching. :)
It would have been great to have a son help you!
My kids help when they can. Some of the work is a bit to heavy for them and some times they are off doing other projects. :)
kitty yo what up?
Thanks for watching. :)
Hope the kitty don't fall in the concrete his color you would never find him hes concrete gray.
We made sure both our cats were accounted for before we started pouring concrete, they both like to find little places to play hide and seek. :)
