How To Tie Rebar : EP.12

Learn how to tie rebar, place rebar, and think about rebar when installing inside of concrete. I think concrete is the most most important building material of all time, especially when combined with steel. It is a beautiful, permanent, strong, and extremely versatile.
One thing to clarify this video - we tied 100% of the perimeter rebar intersections, and 50% of the intersections in the middle.

hey man, a bit morbid but here's something from the bottom of my heart. i lost my dad to septicaemia in 2003 i was 8 years old, he was a tradesman and craftsman, and i miss him dearly. he was half way through building our house from the ground up when he died, when news of his death got around the vultures descended and emptied his shop of all it was worth, it had a catastrophic effect on the lives of me and my mum. there was huge amount of knowledge that was lost with him, masonry, plastering, mechanics, philosophy, business, and i never had a decent chance to learn any of that from him like i should have done, so i'd just like to say that these videos mean a lot to me and will help me rebuild the life of me and my family metaphorically and literally, and help me continue my dad's legacy. so, thank you for it all.

[@5005ginger]

Hi lade you need to go to College to learn all of this?

[@gramursowanfaborden5820]

construction at college here in the UK is full of the idiots who can't think, it's terribly sad, but because of that it doesn't get enough funding to be of much use to people who actually want to strike out and do it to any meaningful degree besides being some apprentice that carries bricks, it's too low level and isn't designed for anyone with any passion or intuition. i've learnt more from this series so far than i would've learned in a year of paid education at college.

[@tienglongmy]

@@gramursowanfaborden5820 Apprentice to a small or up-and-coming general contractor. You could teach yourself but it will take a lot longer. (US advice, not sure how things work in loicense-land).

[@gramursowanfaborden5820]

@@tienglongmy you're right, with the right people... about 9 months ago i joined a program for young people to get them into the construction industry, it was promised to be a full package that gave us the skills, qualifications and experience we needed to get out and about, and technically it was that, but it was utterly miserable, spending half the time on-site and the other half in a portable cabin classroom next to the site office, the tradesmen didn't want us to be there, the foremen didn't want us to be there, and so mostly we were just running errands, and of course carrying bricks (no surprises there!) though i did get to carry some concrete slabs, timber, doors... all the while desperately trying to learn the ropes, learn some skills working with different trades and earn some respect, sadly those actual benefits were lacking. i got my CSCS card (our loicense to work on-site), and that was it, it was a huge disappointment and a waste of three months of my life watching greenfield land be polluted with building sand, nails, plastic clips and broken saw blades being covered in cheap "homes" that won't last 30 years despite leaving a permanent blight for ever more. it has taught me some valuable lessons, but not the ones they intended. i'm still going for it but it's on my own terms now, i've seen some of the worst of the construction industry build some of the worst houses and i will not do it any more, so i'm currently looking at some traditional firms that sympathetically maintain, restore and rebuild historical buildings, Cornish hedgers (similar to dry stone walls), and traditional crafts like smithing, forestry, thatchwork, something that makes me feel as though i'm doing good, conservation, not development.

[@gramursowanfaborden5820]

@pete smyth thank you. i didn't know either of my grandfathers very well either, now i'm the last man in the family. i've got nobody close to learn from, but i'm learning myself, slowly, and thanks to some great KZbin channels like this one. i'm buying some land soon, gonna build a workshop, continue the family legacy whether the universe wants me to or not.

[@tonybutcher4762]

Pure living for life shows us how to do it the hard way . Essential Craftsman shows us how a professional works.

[@DanielinLaTuna]

tony butcher, you’re absolutely right. Got tired of watching amateurs doing rework, although sometimes the soap-opera gets a chuckle from me.

[@TokyoCraftsman]

You are correct, but the PLF never claimed to be pros, EC is a pro with a lot of experience under his belt, oh wait, suspenders, but yeah, it is sure nice to see a real craftsman at work!

[@colinkrs]

Sometimes I watch those two losers just to feel better about myself. Scott here is truly a 're lesson of what I do daily and I couldn't be happier

[@jasons4882]

PLF has become hard to watch over time, it has just turned into garbage with mass confusion. I enjoy EC based on his ability to explain technical issues, and the fact I feel confident in his ability - that makes it all enjoyable.

[@giraffemeat44]

It's become 25 minute videos why they are off a 1/8" on their trusses that they are explaining how it happened months ago in the excavation or something irrelevant. People just want to see them build but I think the process is so slow they've been forced to substitute ALOT of useless footage into their videos, to hide the fact there is no building really taking place. I really liked their channel but since the whole water system adventure to this house debacle they've under taken, it just hurts me to watch sometimes. We'll see if that house gets closed in before winter can completely warp, saturate, and twist every bit of lumber they've spent all fall putting up.

[@JasonSpenc]

Entertaining, intelligent and informative. You are a rare combination, Sir. Thank you for presenting these videos in such a way that is very user friendly.

[@nybirdman]

Here’s the help you were looking for. You were close with your definition of “development length” but there is one major difference. Development length is the minimum length of rebar that is required to be embedded into concrete in order for the piece of rebar to properly transfer the load from the rebar into the concrete. That’s the basic definition but it also has variables. There are tension development lengths and compression development lengths, each is the minimum length required to develop either tension or compression (for example columns on simple structures are typically in compression, while beams will have bars that are in tension and compression, depending if it’s a top bar or bottom bar in the beam). In your video, what you are calling the development length is actually what’s called the “lap splice length” and the name is self explanatory. The difference between lap splice length and development length is that lap splice length is the minimum length of lap required to properly transfer the stress or load from one bar to the next bar as if it were a continuous bar. Development length is the transfer of load from one rebar to the concrete itself, with no lap or other rebar. Please also keep in mind that these minimum lengths, development or lap splice, will vary greatly depending on the strength of concrete you use, grade of rebar you use, tension or compression use, and also the clear cover used (3” off the ground in your video). Often times, for interior columns let’s say, 1.5” is requested and that little bit less of concrete requires a slightly longer lap splice. Sorry for the long response but there are a few variables that determine these things and the explanations require a lot of explaining, which you so kindly do for us so I’m just returning the favor. Let me know if you have any questions. Thanks.

[@judeykun2263]

nybirdman when youre lapping your vertical 'starter' bars then you can say development length.

[@nybirdman]

Oh, i forgot to mention the most important variable, the size of the rebar (its late). The bigger the bar, the larger the development and lap splice length required. Always, always, use the drawings to determine these lengths as a #3 lap splice length can be 16” in some applications and a #11 can be 9’ or 108”. And in case you were wondering, epoxy Coated or “green bar” requires even longer lengths because the coating is smoother and doesn’t transfer the stress as well. Like i said, there’s a number of variables so always check the drawings and know the application. Best of luck to you all.

[@nybirdman]

Judey Kun i mean i guess you can call it whatever you’d like but from an engineering perspective, lap splice length is NOT the same as development length.

[@TheRealFOSFOR]

Just weld the rebar together =D

[@johnbandy8745]

nybirdman I am truly a novice, but have helped build two houses in the past. Somebody has mentioned welding the rebar together and I am assuming this is OK. Could you share thoughts on this, such as how much should be overlapped and welded together if at all? I have built a couple of retaining walls around my house and welded the rebar together to make it one continuous structure because I did not know how much overlap to use.

[@yonmoore]

I dig the jobsite power nap. I've done it myself countless times. A 10-15 minute refresher is by far more effective than any energy drink or coffee.

[@theopiner402]

Essential Craftsman, the Lord has also blessed me with three boys and a girl. It is my sincere hope that I can train them up to be hard workers in all aspects of their lives. I enjoy the content you folks produce, best wishes, and may the Lord continue to bless you and yours.

[@nlo114]

09:10 - while you are holding the verts in place for your mate to tie, put your thumb over the end of the bar. A thumb knuckle in the eye is not as painful as rebar-end in the eye. Carry a shoulder-bag of mushrooms to fit over the ends as soon as they are in place. You only get one pair of eyes, look after them!

[@nicholasmanning1566]

I have watched this particular sequence of concrete preparation and pouring videos I think a dozen times so far. I think I'm finally catching all the jargon and understanding what you are doing. Thanks a lot for putting these to video. It's been really helpful.

Telling it like it's supposed to be....and then doing it. Great job. I truly love watching a professional that can" talk the talk and walk the walk!" ....13

[@jrhunterdb94]

I do concrete in large commercial settings. Typically we get a rebar drawing that shows how all the rebar should be tied and in the rebar drawings there’s a lap schedule that tells you how much lap you should have on your bars. It varies depending on what size the bars are and whether they’re epoxy coated or not. I don’t know if you’ve ever seen that but I figured I’d let you know my experience. Good video.

[@calebburns4346]

The intermission is my favorite part.

[@maxwaters1461]

Good to hear you encourage and promote the permit process, far too many contractors ignore the plans if they ever had any, and do what they think is correct, which 99% of the time they are wrong.

[@andyh8239]

That pneumatic shovel is genius

[@MacMcNurgle]

Hello Sir, I wondered for a small time what it was about your channel that has me as a subscriber. Sure, I worked construction for a few months as a kid. Mixing mud, carting bricks and then doing the reo for in-ground swimming pools. As well as hand mixing concrete for many months as I helped improve the family home. It was not the nostalgia that drew me in. It is that you are an expert. Given the Interwebs allows you to access all manner of idiot and ignorance, having access to an expert is refreshing. Rewarding. Almost comforting. Thank you very much.

Im in the beginning phases of the home building process. I'm a DIY kind of individual, that has turned it into a career. Industrial automation, metalworking, computer programming, electrician, and a few other odd skills ive taught myself to do at a professional level. Residential construction is the one type of building experience i'm lacking. I've been doing what i always do, learn intensely until i'm confident i can at least try whatever it is. I was only a week into an information binge when i caught one of your recent videos in the series. I started at 1 and have been glued to it for 2 days. I have 15 pages handwritten in my black book of notes. Going through the concrete work has been fantastic. With every new fact and bit of information you extol I research and learn more on the topic. Thanks for the insight and information, its been amazing to actually learn this way from someone who has done it.

[@Michaellove85]

Love this series. Great job explaining everything.

[@vashman01]

You have it backwards with the forces that each rebar mat resits. The bottom mat is resisting the tension loads in the bottom of the footing caused by the load from above. The top mat is what helps resist the moment forces caused by the retained slope. Edit: It is the concrete itself that is resisting all of the compression forces.

A concise definition of development length: the development length is the embedment length of a bar to develop its full strength. What you were showing in the beginning of the video was a lap splice. The required lap splice, is as you said, the length in which two bars lapped would be equivalent to one continuous bar. Some great videos here thanks so much for the effort and insight, I have learned a lot!

[@ArthurDentZaphodBeeb]

One of the first videos I watched was about 3 months ago. Love them. One of the new tools one of the videos demonstrated was a power wire twister for re bar installation. It took a reel of wire and if I recall correctly you just pushed the tool against the rebar intersection needing to be wired and pulled the trigger. IfI recall the brand I believe it was Bosch or Mikita. It was blue. I believe there was an extension to let you run the tool without bending over. That help any of the old wire twisters. JoeB

Engineer here. Development length is the length required to fully develop the rebars tensile strength in the concrete. Meaning that, should the rebar be fully developed in Concrete, the bar will snap before it pulls out of the concrete. Hope that helps!

Snap? I'm sure you meant yield...

[@zafarcolvin756]

I still don’t understand why the Overlap Length Has to be what it is. I mean, how are 20 inches better than 4 inches in preventing it from snapping? Also how do you tie the overlap pieces together? Are you doing that with the same kind of wire? Every 1 inch? every 3 inches?

Cover on rebar also protects rebar from carbonation of the concrete. Concrete is highly alkaline which prevents rusting. CO2 in atmosphere is absorbed by the outside facing concrete but only penetrates so far in good concrete. Carbonation reduces alkalinity, allows rusting and then concrete will stall. Cover also prevents cracking of the face as it shrinks during setting. Good luck and keep the vids coming. Rich CEng MICE

[@frednowicki7355]

Obviously ,good idea to get re bar in proper place for structural integrity and proper coverage for rust prevention. However, concrete is not water proof,unless ..........one orders the concrete from the ready mix plant with an integral water proofing material. In footings and foundations,it is always a very wise move to do so. One brand that comes to mind is Hy-crete. If your batch plant does not carry it,with sufficient lead time,I'm sure they can source it or another available brand. Good video !

There's another method of tying rebar using prefab short pieces of wire with loops on both ends that wrap around and you place the hook end of a yankee-screwdriver type tool through the loops, pull and it twists the wire easily, almost instantaneously. Working in 115 degree heat in Southern California, that's the way I built my house. It's a little added cost...who cares. It did the job in half the time and saved my back.
