Greatly appreciate all the time you took to Make, Edit the videos and all the complete details. Definitely the #1 video on TH-cam for most complete and detailed.
this is probably the most complete basic guide to pouring structural slabs ive found on youtube yet. very matter of fact. very informative and covers the details of tools you'll need and skills required. this is good stuff. i just did a 14 yard pour with the help of a few friends. none of us had any experience doing this, it was insanely hard work, but it worked out well, is quite level, just not as perfectly smooth as a professional. you can do it. and buy the good concrete... get the high psi, and reinforce it, do a thicker slab than you think you need, and do the air entrainment if its outside freezing. then if you screwed up on your prep work she'll hold anyway.
Many different designs for each type of project are also included. For example, there are hundreds of designs th-cam.com/users/postUgkxb2mhCug-GkCWrq69Ce2I0nM0D4QpxAqu for outdoor buildings, from small sheds all the way up to a complete stable. Choose whatever type of shed or storage house is right for you. Pick from fancy ones or more utilitarian designs.
This was absolutely the best video on this topic I have seen. You explained each and every step and possible trouble spots. Everything is clearly and consisely spelled out and I feel like every possible question I might have had was answered. Thank you from the bottom of my heart for this information. Outstanding.
Superbly done. This guy is a natural teacher and he's got skills--- Love the scene at around 12:40 where he is checking and securing the square of the corner using the angled brace and he drives home the duplex nail in one smartly administered whack of the framing hammer while holding in the slightly outwardly bowed form with his left knee in alignment. Well done.
Best instructional video I have yet seen. Probably will never pour one myself, but so good to know how it is supposed to be done. Thanks for the effort!
40 diameter min. lap per UBC (different bar size, different lap length ). 2" min. clearance to earth, 1-1/2" min. clearance to air. Well prepared, informative video. Excellent!
Very good and methodical video, love the detail. Why not use concrete poles in the footing? Especially for heavy structures. That will stabilize shifting and cracking.
The topsoil off your building envelope is also great for gardening. It probably won't be enough for a vege garden, but for non-productive plants it'll help a lot.
Good information. We're using different techniques in our area for a vapor barrier. A two inch layer of shredded and ground tires soaked in fuel oil, then burned until a homogeneous layer forms. Both vibration and moisture resistant. The technique is called churn and burn and has proven very effective.
Great video, I was always told that too much water makes a poor mix and cracks easily. Someone please explain that knows what they are doing or wirks in this profession
Amazing job. I bet it's a good feeling to be proud of your good work. In the past, I made a mistake hiring a crooked contractor who did a shoddy job. I'm still mad at it.
Wow. Going through this and I think now I can get an engineering degree, like not achievable in any university! Very well done in all respect including video and sound. I learn a lot through your clip and would like to thank you dearly for that. You have one more admiring subscriber here.
if you staple a piece of an old tape measure to a 4' length of 2"x1" and then clip your water level to that, you won't need to fiddle with the tape measure to check your heights. After that, you could think about adding a spirit level bubble to confirm your stick is vertical.
Nice video. Well done. Very professional. I started off in construction working out of the mason's tenders union in DC where we poured 2 or 3 block size areas at a time with pours lasting 24 hours or longer. I personally did slump tests on each batch which were then also sent off for analysis. We located cracks in a spandrel beam (concrete beam) which then had to be demolished and re-poured. The culprit was motor oil in the sand used in the mix back at the batch plant when someone changed motor oil and allowed it to drain into the sand. So concrete quality is also an issue which deserves more attention. Where money is involved things happen sometimes that should not. We often poured during the winter elevated decks that were completely exposed to the air temperatures where we would have to build tents and place torpedo heaters inside to help control the cure. We would use ellis jacks for each new deck to suspend it while it cured enough to move the jacks up to the a higher floor. And we used pans to create cross beams which were reinforced with rebar. All mechanical systems would have to be installed after the pans were in place (on top of a layer of plywood. We used lacquered plywood to alleviate the bonding and to give a smooth surface on exposed walls. Some of the exposed concrete surfaces were sandblasted to expose colored aggregate which would make a unique appearance. Concrete is a very versatile product but not a forgiving one. Errors would require jack-hammering and hard work. Elevator shafts poured which were off by a small amount would have to be ground down to install the elevator tracks, etc. Some of these large projects would employ hundreds of people to support the process. I eventually moved on to something easier as I got older. Concrete is a young man's game.
Such a great instructional video. I bet you didn't expect people from Bosnia adopting your methods and advices. Also really great tips you share from your own experience that us amateurs will eventually find out but obviously to late :) . Thank you sir for doing this video... Much appreciated
Can't believe how many people on youtube are pouring concrete slabs right on top of top soil. Removing the topsoil like this video instructs is the only way to help prevent the slab from cracking and moving all over the place.
@Rich Brock Sorry, It's never a good idea to pour concrete over topsoil. Sure if it's a small slab maybe it doesn't crack (most likely will) but overtime it will start leaning to the point you'll need to mudjack it or redo it totally. You're not the kind of person who should be telling others what to do when it come to concrete work. Buy a clue first.
Hi, out of curiousity did you have the soil tested to see what is the load bearing capacity. Also, did you have structural engineer review your plans to make sure is structurally sound. Thank you
What is the outcome for the concrete to dry unevenly, is that a good thing or a bad thing? Does this have something in relation to do with the sand bed?
When you say "Coal Industry," you describe quite a scope. Are you talking about the mine as the source for the Fly Ash? Or is it a by-product of the coal burning - at a power plant? We have Coal-fired Power Plants about, but no mines!
we just argued with the concrete tester about compaction on that type gravel; we had a plate compactor and he said it wouldnt work to get a good result; he said to get a Jumping jack compactor and wet it; we got over a hundred! whereas the plate compactor would give us about 40; I will never doubt a SME tester
I was planning on adding to my exsisting concrete slab. I'd be adding 12 inches at the thickest part. Would it be better to just start all the way over and do a completely new slab? If it is ok to add to existing slab what do you use as a vapor barrier?
Thank you very much for everything. Tips such as "remove all organic" awesome!. I'm about to built my 1st DIY home in CA. I was interested in strawbale but with no experience I didn't think it would pass CA title-24 or code compliance. I might do it later as second dwell and after get to know more from city planner. Are you doing strawbale video?
Hi, I am concerned with application of a thin reinforcing steel mesh. It may be inadequate for this particular foundation slab. Also concerns are about placement of reinforcement so far from formwork. This could allow larger cracking resulting in corrosion of concrete. Regards
At ~1:05:00 where the large slap is being poured, they are pouring the concrete directly on top of the pink insulation. Earlier in the video, there was mention on sand being needed in between the concrete and the insulation to allow the water in the concrete to escape properly at the curing step.... ????
Concrete shall never be poured directly on sand or rapidly water absorbing dirt. A plastic separation barrier (or foam blocks) shall always be used. The reason is to avoid the rapid water absorbtion underneath the surface before the (at least 7 days) concrete cures to an acceptable strength.
If you're doing sawcutting on a slab that has walls, wouldn't it make sense to sawcut along the edge of the wall? You couldn't go square underneath, because you need uncut concrete to fix your wall plate to, but a cut just beside the wall wouldn't be a problem - and it wouldn't risk cutting the heating pipes.

Thank you for this tutorial , the best concrete video keep up the hard work , many DIYer's. Are not lost anymore thank you very much.
An excellent and well documented video. This is how how to videos should be made. Very concise and clearly spoken. Thanks!!
Dude, thank you! I wish everyone made videos as informative, helpful, and concise as yours. 1 1/2 hour video and not a second wasted. Good stuff.
This is just the foundation man it’s not like building a rocket
Absolutely the best informed video on how to pour a concrete slab the right way! Thank you.
Superbly done. This guy is a natural teacher and he's got skills--- Love the scene at around 12:40 where he is checking and securing the square of the corner using the angled brace and he drives home the duplex nail in one smartly administered whack of the framing hammer while holding in the slightly outwardly bowed form with his left knee in alignment.

Outstanding! Wearing a mic and commenting on every step was great. Thank you very much for your efforts on this.

This is extraordinarily detailed, and the way you consider every aspect of the land (and associated buildings) is wonderful to learn. Thank you.
Wow ! What a wonderful video with all these detailed info! Thank you so much
Amazing detail and thoroughness I thought I was in a college engineering class thank you GREAT JOB!!!!!!
We can confirm that this is how a slab is poured
That was a wealth of information! Thank you for sharing.

Best 1.5 hrs video on concrete slab pour , very informative. Thanks
Very thorough unlike other concrete vids
just worked on concrete on my own after watching your video. thanks
Fantastic video. Thank you.
You have covered a lot of detail.
Best concreting video on the Web!
Great video. Glad you took the time to explain things fully.
Thank you for posting. Excellent video!
What an excellent full blown descriptive and useful video. Best one I have found on You Tube for this job.
Very good and methodical video, love the detail.

Thanks, Picked up a bunch of great tips!
Thank you so much! This is so informative and to the point!
ReggyRay289
Wow! Kind of job! Thanks for sharing your knowledge!!!
Excellent video. Thanks so much. : )
Very nice video. Thank you! What did you use to slow down the curing surface of the concrete ?
I might have missed it, but can all the rocks and pebbles on the outside of the concrete slab be moved now that the slab is finished?
Nice tip about the brace

Thanks for all the good info
Great video. THANK YOU
wooo you are the man! thanks for sharing this video!
very professional, thank you
awesome i wish i had your talent
good video. I use CUFT divided by 27 = CUYDS ... I just find it's easier to remember
That's definitely some rooky shit there !!!!
this is a very informative video... I'm glad it's free
Awesome video
Your helper is hot. Great video, nice to see someone on TH-cam who knows what they are doing.
the way things should be done, right the only way.
Wow, thanks a ton... Most valuable 1.5 hours I've ever spent on TH-cam!
This video is gold
great video!
Well Done!! impressive video, what a level of details!!

A jumping jack gives you much much better results, but sometimes they aren't available or on a small job like this, it's overkill.
Good vid.
I was planning on adding to my exsisting concrete slab. I'd be adding 12 inches at the thickest part. Would it be better to just start all the way over and do a completely new slab? If it is ok to add to existing slab what do you use as a vapor barrier?
smart! great advice!
Thank you very much for everything. Tips such as "remove all organic" awesome!. I'm about to built my 1st DIY home in CA.

Quality. Very nice...
Wow... tons of solid information, thanks for sharing your knowledge, much appreciated :-)
Hi,
I am concerned with application of a thin reinforcing steel mesh. It may be inadequate for this particular foundation slab. Also concerns are about placement of reinforcement so far from formwork. This could allow larger cracking resulting in corrosion of concrete.
Regards
great video ,
On a slab like this would making the corners a extra 10 inches deep and wide help with breaking.
Fine job. Thanks!
I'm a bit confused, Is the foam board saposed to go all the way to the edge of the foundation? is this just an example?
You found me mums trowel..THANKS!!
Thank you so much sir, excellent video.
Great film. Where were these clips shot?
Where did this channel go
Such good content and then it just vanishes
Could I use bricks with holes in them for dobies?
What is the definition by him saying to take down the slab it's important to move the material?
Very well done thanks
How long will it take you to build a whole house!

Why you didn't put plastic under slab in wall area ???
wouldn't fly ash be harmful in the long run due to the heavy metals in it?
Why didn't you use Shuttering plywood?
You need a compass to find south?
Excellent! Superb! Well worth the ime.
I need to pour a foundation for a thirty-five foot antenna tower - anyone know of a video for that job?
Hire an engineer...
Great Job - to damn many youtube commercials interrupting your project
