Play by their rules. Here in Australia if it on trailer. No permits needed. my mate leaned some wheels up to his house, pur trailer number plate and lights at the back took photos and the councils was happy
Your channel is going to boom soon! Great content, really informative, and I look forward to watching your entire series on this build.
I appreciate the compliments! We had a slow-down over winter. But new videos are coming your way soon.
Hi Van! I have really enjoyed your past videos on wood stoves and rocket mass heaters. Now that you are doing this video on small house, very cool👍. Always looking forward to the next video, I appreciate you putting these out there for us who are always dreaming of improving. Thanks friend!
Awesome, thank you! Don't worry, I have some ideas on heating this little house, too.
Great video and easy to understand the technique Van. Always a pleasure to see you sir! 👊🏻👍🏻😊 see you soon. Tim
Glad you enjoyed it. More are coming...
Looks good, we are going to put a Portland cement, and bonding agent coat, on our aircrete garden wall today. 🙂👍
I have often wondered why I haven't seen surface bonding cement used on aircrete. Thanks for the videos and please let us know how well the system holds up over time.
Great info!
this is brilliant. fantastic work and teaching.
Many thanks!
Hi Van, I was thinking of using a plaster and fiber sheet like they do with aircrete domes but this stuff you are using seems to be much better and less combersome and will do more of what I would like to do, ie waterproofing. the fiberglass in the mix is what gives it the strength and it is along the same lines of the metal Helix micro rebar in cement for pouring floors, concrete slabs etc negating the need for rebar at all that makes it really interesting to me. I guess some people have not heard of these new products and that is why they don't have a clue that what you are doing works. you can also use a thicker aircrete, ie less foam in the mix and use that as a footer and put helix or fiberglass rods in it in order to give it the effect some people are looking for. there is also the stuff that you add aluminum to the mix and it rises after pouring for the footer and is much harder than aircrete but has many of the same effects ie less heat bridging etc. something to look into also a cheap product compared to the traditional stuff that is quickly going out of fashion. they are using this new type of pour in place cement slab mixture that is saving tons of money and time and giving the same features as aircrete only more ridgid as a foot. you can pour it right on the packed dirt as a footer without the need of rebar. something to consider. really like the video and look forward to the next one regarding the aircrete series continued. ignore the guy who has all the answers. many of us know what we are interested in and want the info you have to offer.
That sounds really promising. Traditional American building is behind the curve in rammed earth and packed dirt techniques. But the industry is changing. Thank you for sharing this new technique. I was thinking of going the opposite way- really foamy, low-structure aircrete used as foam insulation. I'll definitely be checking out what you wrote about. Thanks for the info. I'm always willing to learn something new.
Van - thank you for posting your videos. We will be following your instructions for a small pump house in Northern Nevada. Fantastic work!
A pump house is a great place to use this technique.
THANK YOU!!!
Great minds think alike! That's my plan.....to construct a "storage building."
Great job, Van.
Nice! Thank you.
Any videos on the framing of that tiny house? Great videos and info, thx!
Ha! A wood chip compost heated shower wall would be icing on the cake.
Reminds me of the white madusa cement plaster we used on our water cistern we mixed it water and painted it on and wherever there were voids in the concrete we patch those with plaster made with siliocusesand that way we didn't end up with a dark spot on the wall quite often when we were finishing up the tank people would come and see what we charged for one we'd invite them down to talk about it while we finished coating the tank and the nice white madusa cement coating sold more tanks than any sales pitch especially if they came down shortly after we started painting it on as when we started it was quite dim lighting with only the sunlight coming in a 2: ft round manhole as we painted it on the tank would get brighter and brighter until it was light as day down in the tank now I'm wondering if aircrete would work for a rain water tank with the same coating to seal the aircrete and make it water proof maybe couldn't make a 8000 gallon tank but maybe a 500 or 1000 gallon tank
awesome stuff
Great Job... Question: I'm thinking about shotcreting 3" of Aircreate on the exterior of a 40' container for insulation, to use as an office at an off grid in the Mojave Desert. Will the shotcrete stick to the metal container, or will I need some sort of substrate to hold the Aircreate to the container?..
A fine house can be made using chord wood on the bottom with air crete for insulation and a header poured to take an aircrete wall above the chordwood header. The i
Nice Job!
Thanks!
thanks for sharing
Our building and housing laws are a bit different here in South Africa. Depending on the type of land you have registered and how far it is from a local municipality determines what regulations you must follow. On agricultural titles you can convert your barn into a living area with minimal use of residential building codes. Most structure regulations need to be followed, like minimal roof beam size, wall load bearing strength etc. But mostly anything goes.
Vaaaaaan! 💪
like a 1 inch slump consistency?
good video, might not want to encapsulate the wooden posts, it may never dry out after it gets moist..rot.
the surface bonding; that's what i was missing...
What state are you in? Arkansas here.
ky
@@TheTitian69 I think here in AR, we only have issues if we're making the home for someone else but never know. I'm doing a greenhouse as a business but looking for funds ATM. I think waterproofing aircreed will be important. If it's helpful to you, I may do is use an industrial ground cover impermeable under the aircrete floor as to insulate it but still thinking about it as I also need drainage. Water trapped isn't a great thing.
Btw, thanks for sharing the info! Appreciate you!!!
Hey Van, any new aircrete videos coming?
*Yes!!! QUIKWALL!!!!!!*
Exactly- Remember that!? It seems like it's getting harder to find. Maybe like us, it was ahead of its time.
@@TheTitian69
I just check the two "big box stores" (their online websites - Lowes & Homedepot), and it seems they are restocking it sparingly in southern New Jersey, Delaware, and eastern Pennsylvania.
It's at almost $23./(50 lb. sack).
I've been looking into & experimenting with lime mortar.
There are many useful recipes that one can put together.
As long as one sticks close to the basics.
Mason's lime mixed to a putty grade - even type S is good,
fine sand,
approx. 10% pozzolan - such as finely crushed shale or calcined clay
perhaps even a little bit of fiberglass concrete fibers can be added
*Note: IF cement (Portland) is to be added, it should be a VERY small percentage - although the pozzolan eliminates the need for cement.*
I almost forgot: whatever pozzolan is to be used, remember that it is what will cause the hardening of the mortar mix.
Portland cement is less than 200 years old (it's invention).
Here in my County no papers are necessary under 120ft sq. if there's not a permanent foundation. You can go UP though!
Up is always cheaper than out, 1/2 the foundation and...heat rises by convection so you are always warm in winter👍
@@janmiller4673 Here in my County the under 120 square feet without permit is for the footprint. I figure I'll overhang the second story about 4' all around and have a decent sized room up top and keep water away from the footers. Gotta go at least 3' deep here on the footers.
Will my mortgage be put in
Couple of things to think about: can aircrete cure well if plastered with a water/vapor-proof surface bonding agent as shown here and, more importantly imo, when is it ok to have wood in direct contact with cement?
I would suggest using a pilaster and curtain approach for what you're trying to accomplish, where a shorter wooden post on a metal base is placed on top of a CMU or sonotube pilaster/pier/column near the height of your aircrete panels. What is being done here is not terribly different in principle to a really poorly thought out wattle and daub structure. I love the use of aircrete for all the reasons mentioned in ep 1, but surface bonding and a bit of actual concrete at the base of your panels are little more than band-aids where there should be a grade beam and actual moisture mitigation (tons of suitable options that don't cost an arm and a leg). All that silly building stuff aside, your videos have some excellent production quality!
well sir.If Yes aircrete will cure if covered or water proofed It happens all the time with concrete. This wall was not covered on the top edge of the wall with the cement so it will most definitely it will just slow the process, When wood should contact cement? It is acceptable and considered code in every state to have treated lumber come in contact with cement. My post are treated. What I was trying to accomplish was not just water proof alone.. It ads significant abrasion resistance probably by a factor of 5. It also adds significant structural integrity and guards against cracking and finishes well without the need for paint, What product are you aware of that will do all of that for that price and one single application? Yea I didn't think so. Now the walls are locked on to the post and the post are in concrete so they are like peers with some wall load being transferred to the post. What I know and did not share that is relevant is the ground is very deep well packed red gravel on top of limestone solid rock. My grandmothers house a 1/4 mile away has a block foundation wall setting right on the ground no footer been there since 1949. So the hard ground is going to carry some load for sure I got evidence. but a significant amount will be transferred to the post in the ground in concrete 16- 18 inches like a poll barn but more support from ground underneath the wall for sure but also far less weight.. the concrete in the bottom was not supposed to be substitution for a footer. It may fail in time ...all things do.. Treated post in packed well drained red gravel in concrete covered all the way around with a 100% water proof crack resistant cement. How many years until failure do you think I got? How many until total structure collapses ? gonna do a video when done on total cost. The Production Quality that has very little to do with me. Its all Terry the photographer editor producer sound guy his logo on the videos
@@TheTitian69 "What product are you aware of that will do all of that for that price and one single application?"
None, including what you have done - which is the entire point and where you're deluding yourself. I highlighted a similarly affordable route w/ pilaster and curtain that would provide strength and longevity with two additional steps (install grade beam and post bases). I'm sure there are countless other alternatives to boot. The palumboism tells me you're no stranger to shortcuts, but painting a surface dressing as a one step cure all for poor design and execution is a disservice to gullible viewers. Moreover, it serves to cement (pun intended) the role of local inspectors which I, like you, tend to tire of.
@@EdensRemorse Could you be more specific about what the cement is not doing? Is it not water proof? is it not harder to scratch? is it not adding structural integrity ? is it not white ? which claim or is it all you dispute or am I wrong about? when on the video did I claim surface bonding cement made up for poor design?
@@TheTitian69 Sure! Let's start with what you did accomplish though. Concerning the aircrete, you "completely sealed" two surfaces of an object that has six. Of the four penetrated sides, one will directly and continuously wick moisture (bottom), while the remainder will absorb water (both sides and the top where wood happens to be). Keep in mind, that is before any loss of integrity in regards to the coating you applied - i.e. before considering the inevitable and relatively rapid shrinkage and expansion of the wood posts. Nowhere in that scenario does the word waterproof seem appropriate without the word "not" immediately before. Would a raincoat "waterproof" a naked person standing knee deep in a florida swamp?
Did you make the aircrete harder to scratch with that coating? Yup! For as long as it stays fast to the aircrete.
As for structural integrity: it is my understanding from your video that the coated aircrete is not a structural member at all, as that is what the posts are for, no? So let's look at those posts and the effects of the coated aircrete partially encasing them, shall we?!?
To be succinct - super fail. The aforementioned moisture wicking will serve to accelerate wood rot, preservative or not. Don't believe me? 30 seconds into the following vid is enough to show exactly what to do and not do: ruclips.net/video/pu0UIl6ZKo0/видео.html
Or simply google: "wood in contact with concrete."
Tons of options to keep your "structure" (hint: posts) from premature rot. Chief among those is not encasing more of it than necessary (preferably none at all if you want the thing to stand for any length of time) in a concentrated moisture wicking envelope as you have...
Is it white? At this point, the flag you should raise needs to be...
@@EdensRemorse Hey thanks for the response. I have a better understanding of your points now so Now I am better able to respond. I think your right about post on top of cement with brackets would last longer. I do so wish you would have answered the question how long do you think I got until structural failure. You see if you google how long will a 4x4 treated post last in concrete you will see its says 20 plus years and up to 40 in optimal conditions. Now I agree water and or moisture will reach my post never meant to deny that. Surface bonding cement is 100% water proof . I in no way think I completely sealed all moisture out, what I do think is that I significantly reduce exposure to moisture and water that will result in much better longevity on the scale. Ray Charles could see that. Now If I can hit the goal build for under 10k and get 25 years out of it then meets my design criteria. In Times past and even modern times tamped gravel footers can be done. Now to address the silly part with Captain Obvious. Surface bonding cement has glass fibers in it and is designed to for use on dry stacked concrete blocks no motor between, It must bond well enough (thus the name surface bonding) and have enough strength to keep the blocks from shifting or moving under load. I wonder why they dont use curtain and plaster for such? If it has the engineered strength to hold blocks together is it not abundantly clear it is adding to the durability and break strength of the aircrete which I call structural integrity..PLEASE. Plus it gives a waterproof shield like any other water proofing . I do think you have a valid point about uneducated viewers assumptions . In my next video I will speak about the lack of footer and the possibilities of failure and I will mention post on brackets last longer as well both good criticisms. I wasn't trying to intentionally mislead anyone. I chose to use post so I could put them 8 foot on center to screw the forms to them.,, It was so dam easy... when the post rot at the bottom the rebar and screws will transfer the weight to the walls to help prevent sag. My estimation 30-40 years.. I got evidence .. Go ahead ask me.. ok I live in a straw bale house with wood frame all covered in surface bonding cement built in 2004..solid as a rock,, Cement and concrete are not the same thing,
@Van Powell How do you deal with micro cracks. I have noticed that your structure already has cracks at 07:16. There is in fact a team (ruclips.net/video/Ogf2hIboyFI/видео.html) that gave up on air create due to these micro cracks and also the failure to get a consistent aircrete mix.
Before I built the house I built a dog house. That's how I discovered how soft and how much it cracks. I knew something had to done. I had built a dry stacked block basement with surface bonding cement so I figured IF it held those blocks together with back pressure of the dirt against it 7 foot deep I recon it would definitely help hold the aircrete together. HOWEVER I wasn't sure so I have had the backup plan if it does deteriorate to use mortar and lay stone over it. Since I get the creek rock for free. In addition I can always skim over the cracks if it cracks through the surface bonding cement. It's cheap so with these things in mind I proceeded. Now as far as the mix consistency you can't tap the forms like you do on most concrete jobs if you do all your bubbles will just rise to the top. Screws up that consistency thing. Also trying to pour it too deep all at once will also cause the same thing. So we did it in shallow layers. We have had some small cracks but just skimmed over them with the surface bonding cement and it seems to hold . Only time will tell. It's been about 2 years nothing so far that I consider unmanageable. If it does have catastrophic failure I will let everyone know. I went back and looked at the timestamp you mentioned. I see what you're looking at and understand that concern however that is where I capped the wall after letting it dry to add 3 inches to the concrete wall height so the lumber lengths would work out better for me. So the wall has dried and then I poured an additional 3 inches . So that's not really a crack it's a seem of two different pours
@@TheTitian69 Thanks for the detailed feedback. I have just come across this aircrete material recently. I am from Africa, Malawi and think it can be a very cost effective way of putting up structures and helping a lot in need. Your content is awesome. Please keep it up. Looking forward to future videos
👍
hawk and trowel, or pan and knofe....faster and easier boss man.
POSTED NO TRESPASSING
kick Jim the "code enforcer" off your land, and sure him for trespassing...
unless you are a slave and Jim is your master....
I hate to say it, but instead of stopping your posts from rotting, you have accelerated the process. I doubt that your posts will make it five years.
Sir your property is your property and not some govern agents property. Your liability to some one injured on your property is however the same. Codes are not law and a man has no moral or legal obligation to. Only law. Law is the "law of the land" or common law. As a common lore' law jury. And not a statutory/attorney/administrative law(statutory) judge agent of the corporation.
Trust we have not confused you. That is what a "man" has obligation duty to vs. what a citizen has obligation duty to.
Hello William my fellow man Your words bring a smile and they are good to hear and know there a still a few who have the understanding. I spent many years in the study of law. I smell what your cooking and know what you got in the pot. I could go on for days about the subject and even considered another channel on the subject of law and structure of governments blacks law dictionary and legalese and how to use a notice or how to write a law suite or file motions. this channel has an old video on here where I am talking about how to stay in honor. which is base on court room elements. I was trying to explain how to be honorable in challenging a fellow mans claim here on you tube... well not so many views,, Christian remedy in law here on you tube is a MOST excellent word study in law and gets maybe 1000 views. Most Just dont care . I have taken friends in the courtroom to first hand witness me contract with the administrator (talk to the judge) claim my standing ask if any one can dispute my claim. Let them know thats the only way I will be appearing today. Shut the whole act down walk out with no penalty no pleading no bullshit. THEY STILL would not take the time to learn it. I sued Home depot for 10k and won and paid in 3 days. I can fix your credit and all kinds of things like that, I find it all valuable and worth the time to learn. I am in continuous awe that more dont take up the study and IF it was to catch on it changes EVERYTHING. What sort or red neck lawyer skills is your specialty? Know what I mean? what do you focus on and any worthy notes?
