- In this video, I`m gonna explain, how a proper beam foundation in cold countries is built. What are the common mistakes construction workers and engineers do. Why many modern foundations are weak. How ancestors built the foundations of stones. How to prevent the house from capillary moisture. How a good concrete floor is made. How to use rebar and make a proper reinforcement. What backfilling to use.
After watching this video you know all basics of the foundations.

"I'm a big smart ass, so I know alot"
I love it 😂
This is the single best video on youtube regarding how to build concrete foundations yourself.
Aitäh, hea hariv video.
Tore kuulda :)
Good video. Thank you!
Amazingly thought-out videos, keep 'em coming! Future videos should show the whole process of building a house. Starting from your existing project planning and foundation videos to wall building, roof work, fassade work, interior work, etc.
Thanks Robert, this is very special comment to me. That is really my target. One day me, wife and kids gonna start with our home building and by that time I can produce a better videocontent. But now, while we collect finance for a land, I can share my knowledge and learn speaking with the camera. Maybe some diy and material testing projects gonna be on my channel this year.
Great video. I learned a lot about general best-practices for foundation design. Thanks
Great to read comments like so :) .
This is real value!Thank you
Your welcome ;)
Thank you. It is exactly what I was looking for. Very well explained. This Earth has gained another stone ancient style foundation :)
Youre welcome. Northmen has very good videos about oldschool build.
Keep it up bro!
Love the content. 👍
Thanks, this one was so time-consuming :D .
Thank you this was really helpful!
Youre welcome. I am happy that you found that video.
Great! I really got some good point-outs😉
Thanks, I really do hope, that you gonna build many foundations in your lifetime ;)
thanks for this video
Your welcome. Glad I was helpful.
This is excellent advice - thank you. We have just found a piece of land in Sweden and are researching foundation construction methods. The concepts you explain about water absorption and land subsidence are very easy to understand. Your emphasis that a professional builder may not build the best, long lasting foundation is valuable knowledge. Perhaps if you could go into more detail about the beam foundation design process, that would be helpful. For example - how to design in cad, understanding building regulations and critical factors like the frost line. Good luck with your build!
Thanks. More detailed video will be in the future, when I build my own home ;)
Thanks a lot!
I am very happy to share my knowledge :)
this is a great video, just bought land in the woods and this will help alot
Thanks, wish you joyful building process.
Hi, I never going to build a house but the knowledge of why foundations are done this way is worth knowing. The comparison with the old way of building was educational. You explaining that water is the enemy ( kind of ) is excellent, is that why builders avoid washing ?. Seriously excellent work by you.
Hei. Yeah, I also sometimes watch videos I actually don't need to :D For example, I watched how the Burj Khalifa foundation is made. Or how tanks are made. Hopefully, I won't need to drive them in the future :D
What was with builders and washing?
Thanks for your feedback and thoughts!
Just Wonderful.
I 'm planning my house also, so while searching building process of the mouse, youtube algorithm sent me here.
Hey. I am happy when my knowledge is useful for people, who need it. Hopefully this magic youtube algorithm gonna favor my channel more, so at time, when I gonna build a home, I do have audience for my project.
Accidentally stumbled on this video and didn't have any idea I wanted to learn about how foundations are built... but now I want to know more, since it was a great video! Since I'm interested in sustainable construction, how would this same foundation be built in a more eco-friendly manner (i.e. less concrete, less plastic)?
Hey, you can check Northmen yt channel. They built there house with ancestors technology.
Excellent video 🤠👍
Thanks, good you did find it ;)
Great video 📹 👍
Thanks for your positive feedback (Y)
This was very informative and helpful. I am in the process of planning to build a 30 foot by 30 foot cabin and want use a pier and beam foundation. Any advice you can provide would be appreciated.
I need help with knowing how to finish the underside of the floor to prevent moisture, insects and mice from getting into the house from underneath. I could also use some advice on how and what type of insulation to use for the floor that is above ground. If you have any suggestions for how to construct the floor with having access to plumbing and electric that would help too. A video on this would help a great deal. Thank you in advance for your help!
Hey. Thanks for your comment and subscription. I have made two videos about foundations and packed pretty much all knowledge I have in them. I dont have experience with your type of foundation and learning about that is not interesting for me. For sure there are other guys on YT, who made a proper video about your choice. I live in a cold country.
Hea video, jätka samas vaimus!
Tänud toetuse eest!
what is your opinion on foundation consisting of concrete footing, layer of ICF ( inslation on both sides and ease of contruction) then slab inside placed on polyethylene (plastic)then insulation and slab..
Glad I stumbled across your videos, they have been very helpful as I am working on my home design. I am curious about your thoughts on a dome home design; costs, etc.
Thanks for good words and sub. About dome home I dont have enough knowledge, so no material for video. I think, that nowadays there are enough materials to create dome house, but there gonna be problem with furniture and roomplan. For summerhouse I like that idea, where you have chimney in middle of house. Kinda like native americans did live :D
@@MarekKubi You are very welcome, I have been watching all your videos, very useful information. That was an idea (gas fireplace in the center, possibly) I was bouncing around with my designer in the Netherlands. We were also thinking of steel beams and concrete (maybe prefab concrete walls). I came across another designer in Germany who has done homes with corrugated iron. I am thinking outside the box while trying to keep construction costs down.
Actually most animals build nests round shaped, so this is really natural to live in one. I think, that it gonna be hard to build something like so on a budget. Since materials is mostly produced for boxy shape houses. Also can be problems to get permission from region. Project gonna cost more. Not sure, if roof material is long-lasting. Insulation is harder to install and windows may be an issu, since they weight a lot and if they are diagonally installed, then it need other installing technique or window frame.
@@MarekKubi Thank you for the input, I guess back to my block design.
Hea töö, Marek! Hea faktipõhine, igav ei hakka.
Tänud!
Hello mr. big smartass! About stuff I'd love to see in future videos would be, how to incorporate all the fancy sustainability ideas like you see in those earthships (Think of thermal mass, incorporated greenhouse on the southside, rainwater capturing/filtering, etc.) into 'normal' houses while still having good structural integrity. While they can be used in somewhat colder climates.
Or, more in another way of saying it; How to build a great, stable, futureproof, pretty much perfect house... :P
Hey, cool idea, but I can see that coming in the far future, when I am more experienced ;)
Great video thanks.
What do you think about wooden floor joists with crawl space, where the insulation is between the joists, and maybe and extra layer covering the joists from underneath, and only a film on top of the compacted sand? any problems you can think of?
Hey, I can see the problem, when you dont make holes in the foundation. There need to be air moving and ventilating moisture out.
About the film layer I think that better dont use that. Under that soil gonna be very moist and it can do big damage to everything. Just use a proper chemical for the joists against rot. And of course you need to use some special materials to cover insulation below. So the wind dont cool down insulation.
Kruvivaiade kohta paluks videot!
Hei, pole nende kohta uurinud, seetõttu pole piisavalt teadmisi, et huvitav video kokku panna. Siiani olen aru saanud, et neid on mõistlik kasutada ainult väga kehva kandevõimega pinnastel, et saaks sügavale toetuma. Või näiteks kui on kõrge radoonisisaldus, et alt tuulduvat põrandat lihtne teha oleks? Praktikas tundub päris keeruline neid maa sisse kruvida, kuna meil on palju maakive ja tanke pinnases.
Aga tänud mõtte eest. Võiks rohkem taolisi teemasoovitusi tulla kommentaaridesse.
@@MarekKubi Kas Supilinnas Tartus võiks see olla sobilik lahendus väikeehitisele? Pealmine kiht on sajandite jooksul inimese poolt kokku veetud materjal, siis tuleb hea 5-9 m turvast ja siis liivane aluspõhi. Lihtsalt arutlen, ei oota mingit kindlat vastust.
Turvas on minu meelest päris kehva kandevõimega. Vaiad peaks kindlasti liivani ulatuma seega. See päris kulukas ettevõtmine nii pikki poste kruvida. Võibolla väikeehitis kannab ka, pole insener, seega kogemused väikesed. Olen nii palju kuulnud, et plaatvundament leiutati just kehva kandevõimega pinnaste jaoks. Ainult et see plaat peaks olema vähemalt 18cm paks ja armeeritud kahes reas. Siis on ta kandev ja vajum ühtlasem. Peno peale valatud "kandvad" plaadid on juba äri ja need saavad hakkama ainult kandval pinnasel. Järgmises videos siis proovin enda teadmisi jagada plaatide osas ja paar vastupidavat, kuid kallist lahendust lahti seletada. Tasub muidugi uurida ka, kuidas ümbruskonnas on esiisad ehitanud ja siis loogilised järeldused teha. Võib ju olla ka lint täitsa toimiv, kuid võiks igaksjuhuks sokli puhul jätta veidi vajumisreservi. Ja katused võiks olla suurema kaldega, et märga lund nii palju ei koguks.
Great video my friend. I'm going to be building in a very cold climate, USA climate zone 7. I have a high water table on the lot so no basement but I plan on implementing the beam method as you described. You've described the best method, in my opinion. Now I just have to convince the engineers here to agree to let me build that way.
Question: Do you think with the footings and beam poured in two pours with a cold joint between them that there would be any benefit to a capillary break at the cold joint using a plastic sheet?
Hey Ben, thanks for your proper comment. I think that plastic sheet between the footing and beam gonna make a bit weaker foundation. Moisture will anyway move up from the sides. Concrete is not afraid of water, so no point to worry about moisture. Most bridges are made of cement. Just try to protect it from ice. How many centimeters freezing point is in your area?
@@MarekKubi You're welcome. I'm glad to see people doing videos different from the majority, who have been, and often are, wrong.
I don't have the exact frost line depth, as we call it here in eastern Utah, USA, but the Salt Lake City area which is a milder climate (USA zone 6) is 76 cm (30 inches). I would expect a frost line of around 122 cm (48 inches) in the particular climactic zone I will be building my home in (USA
zone 7). I'll let you know the exact one when I find out from the local municipality. I'm in the early stages of planning and design. I just purchased the 4047 m^2 (1 acre) property recently.
Being so cold, the beam method is essential. The land is flat and has a high water table due to its proximity to water sources and impermeable sub-surface bedrock strata but isn't in a flood zone.
Cheers.
Hi, thanks for explanation, could you please do that also to a slab foundation. Do you do the calculations also? Some basic principles for the slab foundation according to the EC would be much appriciated. Thanks
Thanks for ideas. Next video gonna be about slab foundation. Cant tell, when exactly. I dont speak about numbers and EC, since my audience is very wide and I hope, that this video gonna be after 5 years also ranking in the search. Also there are big difference in the worktime-cost in different countries. So I try to talk basic stuff like in this video :) .
@@MarekKubi Thanks, much appriciated.
Very informative video, great knowledge and explanations 👍
What are your thoughts on Foam Glass (Technopor, Glaspor, Geocell etc), to insulate and combat moisture in one product??
Also would you see any benefit for Foam Glass compacted under and around footings to stop water damage within the foundation, providing of course the water table is low enough!?
Thanks for the nice feedback. I never even touched the foam glass. In theory, I believe it is a better material, but you need to touch it and feel the vibes and maybe buy one sheet to test it and stuff like so. Rare in my country, because of the price.
What do you think about post and beam for the cold climate? I can connect the rebar from the beam through cement blocks and then have another rebar concrete beam on the top. it's a single-story building too
Hey Eugene. I dont like that hybrid, since ice can lift up the house from that beam area. Post and beam foundation is basicly low beam foundation. It is better for stability, but for frost-damage it dont work.
have you heard about foamglas? It is basically the same as styrofoam but made from glass instead. I am thinking about doing a pier foandation. But I don't want a slab inside since it is not environmentally friendly. Instead I want to do foamglas, compact it and then put a wooden frame on to the foamglas, fill the frame with insulation and then have the plastic sheet on top of the frame. I believe foamglas has low capillary power so should be fine.
Hei, I heard something, but never seen it on sale in my country. Maybe I should start business and import it here? :D Can you send some link on that product? Sweden?
Hi. Thanks for your videos. I am planning to build a barnhouse in a region where temperature ranges -35C to +35C. Your videos are what I was looking for. For the beam foundation, I thought there should be vertical insulation from inside and outside for the beam? What do you think?
Hey, thanks for appreciating me. Insulation works best from the outside. If it is connected with wall insulation, then just outside is fine. Below the floor is anyway horizontal insulation.
7:23 In the picture the insulation is slapped directly to the plinth which doesn't allow the concrete to dry out in the future. The moisture barrier plastic should always be directly attached to the plinth for ventilation, which is the main purpose of the product.
Easy Sub!!
Thanks Albert!
I was reading some notes from the American Civil engineering society. They stated the foam helps to trap the natural rising heat from the earths core. So it would seem the home is not the only source of heat. Heat typically rises and can transfer via a conductor up down or sideways. In your diagram heat would have to transfer down into the ground under the foundation sideways heat transfer. This seem likely but I'm sure there is heat coming up from the earth as well.
Hey David. Earth heat is less than 10C. Floor needs around 28. Without foam, earth will suck the heat and floor will need very hot water to heat the house.
@@MarekKubi That's good to know because I'm getting ready to build a home with a walk out basement that will have in floor heat. Thank you for posting this.
Hi, I want to build a ground slab 6x4 meters, for a wooden shed, and all the stuff will be by the wall in that shed. Slab thickness maybe 12 cm, should rebar be near surface? Because I think sides get more pressure, than the middle of the slab?
Hey. If the pressure is on sides, then rebar is on upper slab part. If for example only in the middle, then rebar in lower part. If there are heavy chimney in that shed, then two layers of rebar is way to go, if there is no plan to pay for calculations.
@@MarekKubi That will be cold shed, thanks!
How do I build a house which has one room Underground do I build separate foundations for the room underground and for the whole house?
Hey, I assume, that you have a concrete floor? I need more information to answer that question. Is the entering way from outside or from inside of the house? If inside, then do you plan to build a walls on that? You can make both ways, most important part is, how the floor is tied or not to that.
Tervitus! Mitte kusagilt ei leia adekvaatset infot, et kas siis soojustatud fibo lint kestab maa sees või pigem mitte? Mida ütled sina?
Tere Erkki. Meil müüdav weberi plokk on päris kvaliteetne ja see kestab maa sees küll. Kui pinnas on stabiilne ja kandev, siis mingeid probleeme ei teki sellega. Kui pinnas soine, savine või pehme, siis võiks kasutada näiteks frammi betoonõõnesplokke, kuna neil saab armeeringu jäigema teha ja mõne cm vajumise puhul on see stabiilsem. Kuigi ma ise olen betooniusku, siis oma isale ehitasin saunamajale fibost lindi, kuna seda on kiirem ja odavam laduda. Tal liivane pinnas, seega parim lahendus kauakestvale majale. Tänan kanali tellimise eest.
Could it be you are referring to XPS foam rather then EPS? XPS is known to shrink a little as it off-gases and lose R value with time. I found some articles where long term water absorption of EPS and XPS were studied. EPS only absorbed 4.8% water vs 18.9% for XPS. The article is "EPS vs. XPS - Water Absorption" by Amvic building system.
Thanks, gonna read that article later. Many different information on the internet. I like EPS better actually.
What about the foam outside the foundation. Doesn't it get wet? even XPS?
I think it has less moisture problems, since it can dry out better.
@@MarekKubi Thank you Marek. I'm concerned it'll need weeks of sun and heat to dry. Once the Autumn rain comes, I think the foam will spend the winter wet and dry in the spring. Thus losing it's insulation properties when they are needed
In the case of beam foundations, does all clay soil have to be removed from the inside and replaced with stones/sand? Can the inside be left intact with stable clay soil if the house temperature will never be below +5 degrees?
Remove as much, as you need for drainage system, then add stones on a original untouched clay and vibrate it well with 500kg vibrator. Then another layer and again. Mission is to press stones into clay to make density higher. Then place drainage pipes in place and start foundation works.
Clay is problematic, because it expands, when water level raises in it. So if you create drainage system under foundation, then it will play less under the floor.
@@MarekKubi Would you recommend placing the original clay around the the outer beam foundation, or using stones and gravel instead? I've heard that in clay soils, adding gravel can lead to water accumulation, so some argue that using clay from the original soil might offer better protection from moisture.
@@Haralds87 Gravel, so then water can flow into drainage pipe and your land around house is drier also.
@@MarekKubi Thanks Marek
Can I use hasopor instead of the stones?
Yes, if the size is ok for that.
Will this proper beam foundation be cheaper than than a proper slab foundation?
Yes.
Ehk siis vundamendi toestamise võimalustest, kui juba on tagajärjed käes?
Tänud videoteema soovituse eest.
Where would 5000 litres of water go if an interior swimming pool was built on the ground floor and a pipe running under the ground had a hole?
Räägi ventilatsiooni süsteemidest majas
Hei, tänud soovituse eest.
Tere. Muidu head videod vundamentidest, aga jätsid kõige olulisema teema välja mida eestlased ei tee eriti on drenaaz ja vihmavee kanalid millega suunatakse alt tulev vesi ja taevast tulev vesi ära. Olen nõus et EPSi peale ehitamine on lollus. muidugi ka kapilaar effekt sõltub liivast. sõmer liiv peab olema.
Tere. Tänud tunnustamast. Jah see drenaazi teema on mõistagi oluline. Arvan et seda võiks vundamentidest eraldatuna käsitlema. Tihtipeale ei saagi korralikku süsteemi ehitada, kuna arendajad pole äravoolusüsteemi investeerinud.
"Quality is pricy" sounds much more like "You don't buils hause ever You dirty peasant!"... Even if it is true... More like both of em.
We need to go cheaper!.. And possibly left this hous for our grandchildren.
Very good. You are not a smart ass. You just know your shit.
Youre not even an engineer- so why the hell do you make these videos???
Because engineers are not.
Some structural engineers have built good houses on paper, only to have them cracked later by human error. And believe me, there are more human errors on building sites than in your math test. Build a house that eliminates the possibility of human error, or build it yourself, which will take decades years.
