Nudura radiant heated crawl space
HTML-код
- Опубликовано: 1 окт 2024
- This is how to build a frost protected heated crawl space. This crawl space has a radiant heated concrete floor and this concrete will heat up and heat the entire structure. The entire area under the wood floor is considered conditioned space so no venting under there and no insulation in the floor joist. The insulation is under the concrete floor. This foundation is for a camp we are building. subscribe and follow the build. 👍👍
Nice Job! Your right about the rim joists. Last job I did had me cutting foam inserts to fit tight in the rim joists. I have heard that the rim joists can lose as much as 20 percent. I would love to work with you guys but I headed to Vermont.
Yes I would build all my houses like this at the rim joist.
It only took 0ne hour to put the tubing down. The other 30 minutes was spent pulling up pants and pull other regions.
😂😂😂😂
There is a perimeter drain apparently, but nothing for downspout drainage?
Not at this time there is not.
Just a note to those who say “concrete drys up”. Actually, concrete needs water and there is a CHEMICAL reaction to cure concrete. The amount of water in a batch refers to SLUMP. Too much water reduces the PSI strength, while dryer mixes are much stronger (I don’t understand the reason why).
Tyler Ley is a great resource on RUclips about concrete. He explains so much. 👍
Here in Oregon this was done in the 70s. Furnace in garage, ducted to crawl space, using it as a plenum, all floors warm, just cut registers into floor in every room. 3 inch Styrofoam on stem walls, 3 inch under 2,3 inch slab with vapor barrier under foam. Crawl hole in closet floor.
Nice this should work awesome. We did a hatch door in utility room. 👍
Instead of the mesh you could also use plastic staples they seem to work well holding the pipe a bit quicker and easier on your back. Pipe decoiler is cheap and worth the investment.
I use both when doing the hydronics.
I will be interested to see how effective this method of heating the sub floor and letting it rise through the flooring.
Great content. Cheers
Even better is to use Nudura HYDROFOAM and put your wire mesh OVER the pex.
@@FJB2020 I have used it but I get a great price on the blue board. 1/2 the Nudura foam. 👍
It will heat it real good. We have basements that will heat a entire house. This is only 30" away. 😊👍
Plastic staples are a great way to go. We do a rebar grid over the top of that for our reinforcement. 5" slab with rebar is way over kill but works very well.
@@bondobuilt386 yeah that Hydrofoam ain't cheap.. There are some other brands that have similar products, but like you said cost about 2x over standard EPS.
Dude... You're in CNY? I'm assuming you have built some ICF houses?
Hi Chris. Just a bunch of basements
What a waste of mesh, it’s all under the concrete instead of in the center of it !
Bruce I explained this in the video bud.
Did it all the time in Alaska but because concrete was $280 a yard plus mileage we didn't pour a slab. We would plastic, 2" foam boards with tape joints then wirt and PEX. Then just 2" of bank run sand and 4-6" of crusher run over that.
In terms of frost protection, you don't actually need the stem wall here, do you? The "wing" insulation protects the slab from heaving. Couldn't you just build directly on the slab with no stem wall?
Think if I'm diy in it I'd not bothered to much finishing a crawlspace slab....BTW...would it lessen the efficiency of the radiant heat if you poured thinner sub floor slab ?
I would hate to pour less than 4" over foam board. Spray foam I would do 3" maybe. The more thermal mass the better it will retain the heat. 👍
I’m learning a lot from your videos and appreciate your channel very much. The heated crawl space, I assume, is the primary heat source. In addition, will the building require extra heat such as a wood stove etc? I understand it’s a camp so only occasionally used. Thank you
The in floor heat will take care of the heat demand for this camp. I'm glad the channel is helping so many of you guys and gals. 😊😊
Interesting, never seen a conveyor on a cement truck, usually see an additional pump truck
There a bunch here and they are handy. 👍
I ALWAYS LIKE TO SEE THE WAY DIFFERENT PEOPLE DO THE JOB.
I do as well 👍😊
Like the ICF block but I think you should have gone 1 course deeper to at least get to the frost line and that way you would have been able to have more room in the crawl space. I seen my first ICF block in the late 70's and always wanted to build a house using it but never had the time or money to do so I instead bought a 100 year old house and gutted it for way less money.
Really interested in your frost free foundation. If the frost line is four ft - how deep did you dig your footers? Looks like about two feet with the foam replacing two feet of dirt.
Yes we are about 30 " deep by the time we backfill everything. 👍👍
Hey Bondo Built, something I was wondering was how long does the radiant heat tubes last? Have you ever had one spring a leak? I saw in another one of your vids where you pressure tested it initially, but I would still be a bit nervous putting such a heat system in for this possible failure.
I never have had a leak. I got it in my house and shop. It could be repaired if it had a leak. it would not be fun but it could be done. 👍
Love watching and learning. Would you be against carrying a little microfiber cloth in your pocket to wipe the camera lens just so we can see more detail?
Michael the case was scratched up over the lense and didn't realize it until I edited the footage.
Looks like it really dried out from the day b4. I guess 100 mph winds will do that.
I like the foam around the frosty line idea.
R u gonna do some saw mill videos too? Foundation and all is looking good Bondo👍
Thanks Rod. Ya the winds dried it out but now its raining again. LOL Were going to get the lumber from a local Amish sawmill. I may cut up some specialty pieces on my mill for the build.
Great video!! We enjoy watching y'all work so hard!! Really enjoy your videos!! 😊
Awesome thanks for the comment.
Bondo...
Just subscribed. You have great videos.
I work in dispatch, for a concrete company. Would be intersted to hear when you call in to order your concrete, in one of your videos....if possible. Thanks man, keep up the good work....
Daniel I like that idea. I might just do that. Thanks for subscribing. 👍😊
That's also a really sexy concrete smooth finish. Glad you didn't fall in when troweling lol
Thanks.buddy. Ya I was close to falling in. lol
i heat my house by putting gas space heaters in the basement. this is the same concept. works for me
It’s been a while, Bondo, and good to see a new video. I imagine that winter had something to do with lack of videos. Great job!
I did a bunch of videos on the tiny hunting camp. Like 15 videos buddy. 👊We dont pout concrete in the winter. 😊
I'm in north central Georgia and a lot of your cold weather precautions don't apply. (In 50+ years here the lowest temp was +8 F - one time only for a day. Usual extreme lows are mid to high 20s. Our frost line is 8" and that's with fudge factor. All of that said, I learn something new with every video that I can maybe put into a DIY project. I used to swing a hammer for a living so I can tell when a contractor is shoveling stable gravy. None of that to be found here. Dang! You broke 9K subs! Grats. The elusive 10K is just around the corner.
Thanks so much Bill for the support. I really like doing this and its rewarding to get nice comments from all of you. Its hard to believe I will be at 10 K soon. 😊👍
I think you will need to run 160 deg, water to keep that concrete at 135Deg to keep the air in the crawlspace at 100deg . to keep the house at 70 deg. Or, cut a lot of vents in the floor and run a blower to move air into and out of the crawlspace. I would have put the concrete and tubing in the house floor. . 120 deg. water and 85 deg. floor.
I got this in the basement floor of my rental property and it works awesome. I was gonna put tubes in floor and ended up not needing to.
What did you use for waterproofing the exterior of the Nudura? Is it a peel and stick and how does it terminate down around the footers? I like watching these ICF videos because everyone has a little different process
Nudura makes a peel and stick but so does every ICF manufacturer. We been spray foaming our basements with closed cell foam as a water proofer. run the peel and stick down and over the footer. 👍
I like the way you describe all the action takers and details of their work...Congrats to you and your team Mr. Bondo...Yves here(pronounced Eve)...
Thanks so much I appreciate the comments 😊😊
Nice job
Thanks
Love the project! Keep the videos coming. Have you used other ICFs? Other than Nudura? Getting ready to build our own home with Nudura and they just raised the prices 23% :( so I'm shopping around. I understand prices on everything are going up right now but that's a lot and they did it in the middle of our quoting process, like we was ready to write the check! Any suggestions is greatly appreciated. Thanks!
I do like the Nudura best but I have used Logix and they we're pretty good blocks. Sucks everything is crazy high right now.
when you use concrete with gravel it looks a little tan
Yes I see that. It greyed up when it dried. 👍
I’m sure you’ve been ask this question a thousand times, why heat a crawl space ?? Great Video 👍 Thanks 😊
The crawl space will heat the entire house and be nice and dry. It just becomes part of the conditioned space. 😊
what will you use to heat that liquide for heating.
Great video.....as usual. Thanks for this. I’m building next year and this helps me understand the process. Do you recommend pressure testing the tubing before the pour?
Thanks 😊 We generally don’t and have never punctured the tubing. If you are worried you can and some people always do but I think it’s unnecessary.
Thank you for making these videos. The best ICF videos on RUclips.
Your welcome 😀
This is a Great channel. Everybody should subscribe! Bondo, I like the Karl action on this one. Also good explanation of why you didn’t pull up the mesh. Keep em coming.
You know I will uncle Jim. The channel is definitely growing.Karl is a natural in front of the camera. LOL I appreciate the support from you all too 😊
I reckon it'd take a bit of time to warm up if you're coming home from a holiday - might want a programmable timer to tell it to start up a few hours before your ETA. And you're obviously not going to zone it. But for soil areas that give you a lot of rising damp and mildew or mould, this would put a stop to that before it starts. Also, respect to Biscuit for the attention to detail, making sure that even this pad of concrete that will be hidden under the floor and never looked at still has a professional finish. Nice work.
Thanks 😊 Biscuit is a perfectionist
Ralph: all that beautiful work- labor and materials, four courses and it would have been a basement another whole sq of home !
Yup true. I don't think he needs all that room for this little hunting cabin. 👍
:)
Thanks 😊
This got to be the best time in the world i come across you guys. Since ive been interested in this method to rebuild my home that burnt down this winter.
Best video(s) Ive seen on the topic..layed out good, with good work habits..I could go on...ill just say, nice job
Well thanks for that Marc. Sorry your house burnt down. If you have questions just ask. 😊
I don't think the one guy wanted to be on video... gave us the California howdy.
Nick thats my buddy Frank. He always tries to slip one in and I usually delete it but I missed that one. California Howdy. LOL 😂😂
Why do you need to pour concrete, radiators in air would work in a crawl space just as well, wouldn’t it?
Charles radiant heat in concrete is alot different then radiators but yes it would work but not as well in my oppinion. Heated concrete is awesome radiator bud. 👍👍
Great job Bondo. I guess you did similar heating system to your rental unit and it works very efficiently.
Thanks. That one was in the floor joist. I think this one will work even better 👍👍
Im just west of Auburn Ny whats your company name to get some work done
Rob we have so much work just around my area I have to turn it down. I work in Oswego county only. Once in a while Onadoga county but not much
It is nice to see a contractor in NY North Country putting out some videos. Keep up the videos. Thank you.
More to come! Thanks for watching buddy. 👍👊
Thanks. It's tuff as nails finding the sequence of videos for the crawl space camp build. Wish there was a different way to group them....
Have you ever put on a concrete roof?
I never fail to be impressed with you level of workmanship.
Thanks John. 😊😊
Great information! Thanks for your insight and experience. Even at 60 yrs old I’m still mesmerized by construction workers doing their thing. Maybe I should have gone into trades instead of the Army then computer science.
ya but what about that wire lol
Jess is doing good with the camera work thank you for the video and thumbs up.
Yes she is thanks Richard. 😊👍
I would be curios to know how clean the stone is in that concrete. Next time you get crete with that mixing truck take some of that gravel and do a silt test on it.
Ya Greg it was a little brown but greyed up when it dried.
Have you used the insulation that has the pegs to clip the pex tubing to ? It is spaced at 6" centers , the pipe clips right in , no zip ties needed .
Steve yes I have used it. It is nice but twice the cost of my setup here bud. 😊
whats the life of in floor heat in a slab? What if a leak happens?
Should last 100 years they say. You can repair a leak but it's a pain.
@@bondobuilt386 For it to spring a leak the plastic has to give way and then the water has to get through the concrete. If the concrete cracks badly enough to break the plastic, whatever caused that has probably destroyed the rest of your house anyway. I reckon you're pretty safe here.
@@tealkerberus748 Agreed 👍
If you were running lines underground from the crawlspace to something like an outdoor wood burning furnace, is it better/easier to run lines through the blocks before pouring or boring through the concrete after the pour???
Great job Ron. Looking forward to more videos. 👍👍
Thanks more will be coming 👍
All the steel is below the slab. It doesn't do any good there!
ifs you watched the video I explain this.
Footing!!🇨🇦👈👍
To nice to cover up. Put a window in the floor.🤗👍
Thats funny. LOL Thanks
Did you put on a drain or two? What happens when water gets in there?
there's a drain around the perimeter
Looking good. So the heat will heat the crawlspace, and then the floor above, I'm assuming? Interesting. Hey bondo, you mentioned you have more nudura jobs coming up this year, I'm really interested in this icf construction, I'd offer you a free days labor, in exchange for learning how the details go first hand. I think you're from the Watertown area right? That's only a couple hours from me.
Broke I'm in Mexico New York. We do have some more ICF this summer. Reach out to me on facebook and maybe we could connect at a job this summer. 👍
Mexico is a little closer, I'm in Canajoharie, N.Y. I'm not on Facebook, do you have an email I can get in touch with you?
@@brockwagner939 rbond360@yahoo.com
Excellent! this is what I want to do for my next house.
awesome John 👍
Awesome job love the conditioned crawlspace
thanks John. 👍😊
Nice work fella
Thanks James. 👍
Train Jess to edge, you need someone light weight. What was the black wrap on the walls. Was there a drain line on this house? Are you still working your night job? You have a good crew there Ron!
Thanks Tom. The black paper is water membrane as a damp proofer. We have a complete perimeter drain around it to daylight. Tomorrow is my last night at my regular job. retiring at 20 years and 50 yrs old. woot woot. lol 😊😊
@@bondobuilt386 Congratulations, I took an early retirement at 53 and my wife worked me harder than my job. Lol
@@tommckinney3947Thanks buddy. I have many projects to finish up around my place too. 😊😊
What is the expected life of the tubing? Is it not subject to damage from the wires or when the concrete guys step on it? What's the spec/type of tubing? Thanks. Why is it called a camp?
The pex should last 100 years. It is 1/2” oxegen barrior pex tubing. It is super tough I have only seen it damaged one time by a kink in all my 100’s of pours. This is a hunting camp for this guy.
@@bondobuilt386 Thanks Ron. Sorry for the simple questions. I'm in the high desert, but the idea of a passively heated floor is appealing. Darn it! You should move to Texas! ;-) Great stuff!
@@butopiatoo Thanks bud. Texas is to hot for this boy. LOL 😂😂
Great day for foundation work!
Definetly Michael. 👍
That won't work in Michigan you will end up with a crawl space 120° and it won't radiate threw the 5/8" flooring then threw the pad and carpet . Iam a 36 year heating contractor and I have witnessed this .
It would definitely work in Michigan. We live in a cold climate. Upstate New York. Worst case we would run tubing in the upstairs floor as well. I have a rental property that only heat is in the basement floor and that's a full basement. We dont do carpet and pad though so that might be different.
@@bondobuilt386 time will tell but you better have the tubing READY fot the 1st floor . I know better believe me I have been called in to solve the problem and the crawl space was over a hundred degrees there heating bill was over 400 dollars a month 2400 sq. Ft. Single story home and they couldn't get the 1st floor up past 60° . We installed floor registers to let rhe heat come up but even that didn't fix the proublem . They finally installed radiant heat under the floor and insulated under the joist . The heat under the crawl concrete was then useless . The home was new build with 2"×6" and foamed with open cell insulation . That's my experience and don't understand why it would be different in a colder climate . But some people just can't be wrong.
Terry I will do a follow up video to let everyone know if I am wrong but it works in the basement at my rental property for 6 years been running just the basement slab and its real cosy ion that house. Not like I hide my mistakes I video everything I do to help others.
@@bondobuilt386 It's been a year, are you able to say something now?
Old Dog, new trick.
Yup 👍😊
Great Job Bondo! I'm looking at tractors for my new build. What size is that Kubota? Does a good job around the foundation. Looks like it's what I'm looking for.
Thanks. Karl the Kubota is a MX5100 Hydrostatic. I love this tractor. I use it almost every day bud. He is a work horse. 😊👍👊
@@bondobuilt386 Thanks Bondo
@@dunep6465 You bet. 👍
@@dunep6465 No problem. 👍
I do a lot of crawlspace repair and that looks like a dream crawlspace to me
What area of the country are you in?
upstate New York buddy
Looks good, the concrete floated out smooth.
Yes it had a nice paste to it on top. Was different then I am used to but finished up nice. 👍😊
14:40 - brilliant frost protection there! Bondo Built is the only one doing it this way. All the other YT gurus would simply have dug an dug and dug to get the foundation down below the frostline. Bondo Built is showing the way!
Thanks I would much rather do it this way.
How much does frost line foam shorten your depth above the 4 foot frost line?
Hi Michael the foam can replace all the dirt all together but you want it down at least 6" below the surface of the ground to protect it and it has to remain there forever.
The IRC r403 has dimensions all lined out. It is based on the air freezing index, and has different foam requirements to match each situation. The IRC only references heated buildings but there is a detail for unheated buildings as well, but you need to buy the code to read it. I will likely end up doing that for some of my stuff. I have a great monolithic detail I use that makes it really easy to build.
@@joshualruby I would like to see that slab detail buddy. I love learning new tricks. 😊👍
Forgot to mention, enjoyed this video as I do all your vids. You are quite a talented man!!!
Thanks Chad I enjoy this work. 😊
@@bondobuilt386 It shows.
Thanks Bill.
Looks great! Can’t wait to see more.
Thank you 😊
Where is your crawlspace access?
Jim there will be a trap door in the utility room. 👍
@@bondobuilt386 awesome idea
@@jimclark7917 Thanks Jim
How does the shape of the rock impact the concrete?
The aggregate is one of there things that will effect the concrete the most. Check out Tyler Ley on youtube. He explains it real good. 👍

awesome. I want to go to camp!
Gonna be a nice camp. 👍👍
Nice work there Mr Ron
Thanks Jeff. 👍👍
Really liking this place
Thanks Ed. We will be doing floor joist tomorrow 👍
Love your videos!
Thanks Michael 👊
Nice!
thanks. 👍
Hey on your next video could you take a minute to explain the foam on the ground inside the foundation and especially the foam on the ground outside the foundation. I don’t quite understand how putting it horizontal a couple feet under the ground does anything for your footers.
All I can think of is maybe it artificially raise is the frost pointto above the footer. I just wonder how drainage and stuff will work
Kyle I have stone and a perimeter drain to daylight under the foam. The easiest way to think about it is the foam takes the place of all the extra dirt to go over the footer to stop the frost from heaving it. Also the drain gets rid of all the water and that stops the freezing too. The foam on thge inside strops the heat in the pex from going down into the ground and makes it go up into the concrete slab and that heats the structure. 😊
That almost looks like a huge shallow pool lol. Great video, it looks like a great product. If you don't mind me asking, how much does something like this cost?
Cost depends on the soil. The soil here was bad so stone needed to be hauled in. Probably 15k believe it or not. Prices are so high for everything right now.
@@bondobuilt386 15k for a massive swimming pool not bad lol. Are you saying 15k for what you've done so far? I don't think that's too bad.
@@SinnisjInsulator Ya around that for where we stand right now. Would make a sweet heated pool. LOL
@@bondobuilt386 that's a great idea, it would work so well with your inground heated system, lol.
@@SinnisjInsulator Ya it would. 👍👍
