A concrete masonry unit (CMU) is a standard size rectangular block used in building construction. CMUs are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them.
Those that use cinders (fly ash or bottom ash) as an aggregate material are called cinder blocks in the United States, breeze blocks (breeze is a synonym of ash) in the United Kingdom, and hollow blocks in the Philippines. In New Zealand and Canada they are known as concrete blocks (a name common in the United States also). In New Zealand, they are also called construction blocks.
In Australia they are also called Besser blocks and Besser bricks, because the Besser Company was a major supplier of machines that made concrete blocks. Clinker blocks use clinker as aggregate. In non-technical usage, the terms cinder block and breeze block are often generalized to cover all of these varieties.

Important note: Local building codes may not allow Romex wiring inside conduit. So you may have to use conduit rated wiring when installing your electrical inside block wall. The concern with Romex wiring is possible overheating inside conduit. With my current electrical setup heat is not so much an issue because. 1: Its inside a basement wall that stays cool year round. 2: Larger 3/4 conduit was used. 3: All electrical runs are somewhat short. With all that being said when your installing wire inside conduit the best option would be to use conduit rated wiring.
@@wolfgangunger217 I have a feeling it is also illegal to bury conduit bodies such as T condulets inside block. Any box must have access to its opening .
@@oldtimer1467 That is also true...the NEC says that these things must be readily accessible which means that nothing needs to be moved, removed, etc. to access the junction box or conduit body.
@@oldtimer1467 This installation does provide access to the junction box.
@@wolfgangunger217 This installation does comply with access to the junction box.
Individual strands of THHN (solid core or stranded) and an electrician's wire pulling snake are actually what's needed here, and much easier to accomplish this wiring job with. Those mini "T" conduit boxes are really difficult to get either 12 or 14 AWG solid core strands of wire through too, let alone ROMEX. (Been there, done that with the single strands, NOT the ROMEX)
You’re a good teacher because you are patient, and You repeat the key words and the basic steps
your videos are amazing. truly the best of youtube. thanks from Australia!
Thank you
Great video . As a total beginner I just ran some wires in conduit. No codes where I live so I tried to pull Romex . My neighbor convinced me to use 3 strand THHN wire. Omg so much easier to pull the single stranded wire with a little wire lube it pulls so easily .
Your neighbor is smart and it is NEC code. Just because you don't have a governing authority does not mean no code. The reason why Romex can't be installed in conduit is the insulation can hold heat. Normally in walls the insulation provides protection but has more room to dissipate heat, not so in conduit.
Awesome video. I am building a block garage in the spring and I loved watching a video that reinforces that my plan is reasonable. One quick thing, where I live, we are not allowed to put romex through conduit, has to be individual THHN conductors. You might want to mention that on you videos otherwise a lot of people may have re-pull the wire if they get a cranky inspector! Awesome video.
Not allowed to anywhere, other then a few exceptions involving sleeves which have to meet certain requirements.
You are an AMAZING Teacher! I’m a 61yo widowed female, planning to go offgrid next Summer. Your videos gave me all the confidence I needed to do this myself (though I will require help to lift the walls I’ll be building for the first floor above this basement.
Thank you so very much for these videos❤️❤️❤️
thank you
What part of the country are you in? I’m 60, and I’ve been wanting to build something like this for a while. I can lift heavy objects for you.
Just what I was looking for thanks.
Beautifully done. Just what I was looking for.
Most excellent - you are a natural born teacher with your concise step by step comments. You should get a job a technical school as an instructor and those students would be blessed!
Thank you
Dude, awesome video. Thank you so much for sharing (great video)
Thank you
appreciating the series.
Thanks
Where I live, the common practice is to finish building then cut holes in the walls to run your conduit. I find that method upsetting and mad because you will always notice the imperfection in the patch-Upwork later and for someone like me with a little tint of OCD, i always find it unnerving. This method you showed not only gladdens my heart but it also shows there are people out there with stuffs that shows a good work can actually be done without disfiguring it. I have been contemplating on doing surface wiring for my home since I don't like the idea of then breaking off the wall to lay my conduit wiring, but i was not sure of which will upset me more, glaring at wires or the not so perfect patched wall. I am definitely sitting with my workers to see how we can make something beautiful like this. Can you recommend me to more videos of this method. Thank you.
great video and explanation mate! well done! thank you for sharing!
Thank you
This is the only video I've been able to find covering the subject of conduit inside a CMU wall. Thank you! Could you do this for an entire new house build?
You would have to check with your local building codes to see what is allowed.
Very detailed. Thank you!
Great video! I love it!
Thanks for the video this all helps aning to build my own house in the woods
Your welcome
I'm moving on to the 3rd video and I have to say, best one I've seen. I do want to express a concern about filling the first 3 layers after electric work. Even with vertical rebar, a flat wall will be a weak point between the lower and upper. That being said, i plan on doing this, either leaving half of the cell per brick empty or taking something that can push into the cement to give the next pouring a place to fill. This will keep there from being a shearing point in the wall. Kinda like when they bind two pieces of 2x4 to make one 2x4. What do you think?
Im a fan now!!🤗🤗
Awesome.!
you are the only one i found put boxes inside the wall. can you share how you do it for concrete ceiling? (or full house) Thank you!..
it looks better but I rather have conduits exposed, great job by the way, the family teamwork rocks👍
Very nice.
Planning a large shop, and your content is invaluable my friend, thank you! Seth
《Will be visiting and viewing quite often, KUDO'S brother! 》
Thank you
@@D.I.Y._All-in-One You are welcome!
Seth
great video!
Gr8!
Nice learning. Is there any damp proofing or not needed? Thanks
Nice video. However the vertical and horizontal rebar should be tied together.
i dont think its necessary to build the electrical inside the wall. You have to insulate the inside of the room regardless and so you can put the boxes in your inside wood/drywall/insulation walls.
1:55 since I can suggest, keep your material wet so no noxious dust can be exposed when cutting.
i can say u are smart guy like me :)
Love the video. I was wondering if you used the 12-2 Romex wire for convenience sake versus using 3 individual #12 solid wires? I've never ran wire inside concrete block and was wondering if this is a code requirement or just a personal choice for you.
Personal choice and was easier for me.
I didn't know code allowed that romex in conduit
It's depends on the local building codes. The main concern with romex is overheating. The basement walls stay cooler because its underground. I also used larger 3/4 conduit. And kept the runs somewhat short. The Romex would become more of an issue if its in concrete above ground where the concrete can radiate more heat. That being said I should have mentioned the issues with romex inside conduit.
dear MS. first thankyou so much your work is very helpful, but as i have seen on your work specially on corner you just simply bent the pvc since there is no column if there is a column how can we bend the pvc
what tool you use to get the joints in the block exterior
Nice video. Not perfect, but neither am I. Tip; try using stranded conductor when fishing through conduit, especially with bends (90°) in it. It tends to go around corners a bit easier than solid conductor
Depends if you are pushing or pulling. For short runs like in this video I push solid any day. If it's long runs requiring pulling with a string or fish tape then yes stranded is better. Where he made his mistake wash using Romex instead of proper conductors for the job.
Does a small basement like yours have to have a french drain and sump pump? If so how do you install it?
Turning boxes 90 shouldn’t prevent remaining parts of ‘system’
What I like the most you are real
Thanks
Just one circuit for all those outlets? 3/4 inch conduit would have carried a large number of thhn 12 wire.
Is Romex by itself approved in block walls?
@@MoneyManHolmes No to Romex, and he has plenty of room. For general use he can have 13 outlets on 1 circuit and 3/4 can hold like 6 circuits, of course then you get into derating wire, upsizing, and all kinds of math.
How deep is that block?
I purchased a home in Alabama with open/unfilled concrete block foundation. The home was built in 1970 & existing romex electrical is run inside the block foundation walls on first floor. I was told by a contractor this is a code violation. I was told by another that it can be in block, but should be sleeved with PVC conduit. I was told by another that conduit is unsafe due to higher temperatures & fire risk.
Does anyone here know the correct code for Alabama? I have not been able to find a definitive answer to this. I'm planning on eventually finishing the first floor/basement. Wondering if I should pull the romex from the block & staple it to studs when I finish the basement? It seems to me it would be safe from nails/screws inside the block, but I'd prefer everything be up to current code. What are the reasons it would be a code violation inside the block? Moisture? Abrasion? Heat???🤔
A couple things involved here. No Romex can not be ran in side block walls because code says so. ( abrasion ). Block walls have to have conduit ran to protect conductors. I think the heat issue mentioned was based on Romex inside conduit. Romex can not be used inside of conduit because it builds heat. There are other types of conductors that are used inside conduit.
Can you run ethernet cable in the same conduit as electrical?
A separate conduit should be used for ethernet, because the power wires will cause interference.
@@D.I.Y._All-in-One good info. Thx.
I'm not an electrician, but it's my understanding that HV and LV wiring can NOT share the same conduit or wall boxes.
It's more of a life-safety issue than interference, although for other kinds of cabling that can be an issue as well. (Probably not such a big deal with Ethernet because it's a differential transmission, and low-frequency [50/60Hz mains] will be rejected pretty easily by the receiver as common-mode noise. And it's way out of the frequency band of interest.)
♥️♥️♥️
just confirming that you didn't actully use grout for the filling of the cores... you used concrete right? Grout has no real structural strength compared to concrete.
nothing wrong with NM in pvc! 🙄 suddenly everybody is a master electrician
