How to Build, Setup and Pour a Room Addition Foundation 

Makita tools are great, I like them. Either those or Hitachi. Always impressed by the range of skills you have. You're a landscaper, plumber, gasfitter, bricklayer, a carpenter AND a great concreter!

I certainly hope that other contractors from around the United States is paying attention to your superb and detailed details and not cutting any corners. I am always at awe to see how you apply such a high level of detail and do your work with perfection and never cut corners.

The professionalism is evident in the video.

Thank you for explaining the 6" sloped edge features, I learned a valuable technique !

No it expands when it gets hot and can cause leaking. Happened me. Solder threaded fitting to a short pieced copper and cool it before screwing in in. And keep a wet rag handy to buff it. Makes it shine and remove flux. Great job on the slab. Haven’t heard anyone talk about calcium I believe is was More than 20 years ago since I seen it used.

I must be an addict. As soon as I saw there was a new video from you on my subscription page, I got comfortable and hit the play button. Great video, great explanations and great attention to detail as always. Keep the videos coming!

Little bit of advise from a plumber. Never solder underground always braze the joints. If unable to braze the joints the use soft copper underground and always sleeve your copper never leave bare underground.

I've learned so much from your channel. I'm much more knowledgeable about concrete, grading, framing, time management etc. I live in Tempe Arizona, but if I lived in southern California I would definitely use you and your crew.

I love this channel! Gives a really good overview of what it takes to star and addition.

Odell Complete Concrete and Plumbing ,,, Who knew ,,, Great Job as Always David ...!!!!!

Great point about your 6 inch over hang about water run off; again great attention to details.

Wow, no frost line. First time I have ever seen a couple guys casually dig the footer by hand, lol. Must be nice.

BTW, any concrete slab for interior living spaces is required to always have a vapor barrier for the reason you mention about moisture coming from the ground.

I love the way you guys work.

Excellent work! Keep videos comming. I love to see job that you do!

That little quarter inch on the valve is also used as a bleed fitting when draining irrigation lines for the winter. At least up in the northern climates like where I live.

🤣they look funny going back and forth real fast..!!

love the videos, im not a concrete guy but its always a good informative watch especially that im looking to transform my back porch to a room

I wish I had the money to add to my house. My future plans for my house is to add a bedroom for my daughter, an actual walk-in closet to the master & an actual laundryroom. Hoping to start next yr..if not then the following

Beautiful work guys that was a smooth job👍

you can tell a guy is very experienced with concrete finishing when you see him talking on his cell phone and bull floating simultaneously. he makes it look too easy.

Great work as always. True legend of the trade!

Beautiful work mate. Cheers from Down Under.

Great transformation. Even before the structure goes up, how the back yard has improved.

Well done!

Awsome job guys

Nice job. So knowledgeable and professional. Wish you operated where I live.

That cat was like wtf you doing people. 😭

Here in Michigan we use chloride , but it works best with hot water.

Good honest work sir. Thank you for the presentation.

Since I enjoy watching your guy's videos so much, can you guys upload about 3 videos a day? Just for my viewing pleasure. Haha. Man!! That was a nice beveled edge. Especially looks like you guys just eyeballed it!!

The LATEST and GREATEST

Another great video !!

I like that perimeter slope. Thats really going to keep things dry.

I think lwill became mad man and that because you Mr.Odell very perfect work👍 you genius king of concrete

Real nice professional work.

Good job

Please feel free to throw that old laser level away in my trashcan, lol. Good vid!

See now you said you would have put that thickened Edge in there for nothing and that's what I'm talkin about you know everybody's always out to get what they can get and not actually taking care of people so my hat's off to you to Odell concrete for not trying to get every single penny they can out of somebody if I didn't live in North Carolina are we get you guys to do some concrete work for me

Must be satisfying to finish a pour like that. So rough at the start, but the end product is great. I noted that there was a stake in the center during the concrete pumping and the initial leveling with the 2X4. I have to assume that was driven down through that plastic liner? No issues foreseen with that hole in the plastic? The answer is probably self evident, but I was curious.

Great vid man!

That 1/4 inch fitting is not to tap onto it is actually a drain for the line on that side of valve usually used to drain for winter

get down👍 uncle David remember your master blaster from Lancaster

Wow lots of work for two guys? Great job

Have you ever used a sod cutter machine instead of shoveling all the sod out? I rented one last summer when we were getting some concrete work done at work and I wanted to put the sod elsewhere on the grounds. It was amazing how quick and easy it made the whole process. I never want to shovel sod again.

Hey guys love your work, I've watched alot of your videos. I like how you give step by step on your process and the reasons why. One question, how long can you let a slab sit before you start to build on it??

Great job boys

Very nice, informative video.

Good job, men.

Beautiful slab bro

Question, should the re-barb for the slab should have been tied to existing foundation by per-drilling holes?

Great work

Nice job 👍

Excellent work as usual! David, if I understand correctly you're going to toss your old laser level once you purchase a new one? If you'd be willing, I'd love to take it so that I can understand the basics of how to use one. I'm working towards my C-27 contractor's license, and would greatly benefit from learning how to use a laser level! As always, thank you for your hard work!

Cat is supervising.

Good content 💯

Hello David, your videos are very informative and well assembled for clarity. However, I was wondering what would happen if too much of the polar drying agent is added to the cement mix ?

Wouldn’t you rebar tie into that existing slab especially since you poured on vapor barrier what if it does flood or get really wet wouldn’t it be possible that slab moves even a little bit and cause cracking or separation From the main structure ??

Kudos right off for the intro music.

nice job guys...

It would be great if you can make a video on how to grade the area and get a nice 2 inch slope.

Great work as usual. That’s going to be an off addition. Wonder why they didn’t just take the concrete all the way to the wall and enclose the whole thing. That little strip of dirt is going to be awkward. Wish I could see what it looks like with the building. I’ve never seen a prefab set like that.

Thank you for you awesome video's they are educational. If possible at all..........I would like to see how you would pour a concrete floor for a underground cellar. Soil type is clay.

Another great job. Curious what do you do with the wheelbarrow full of watery concrete? I guess the first little bit starts out too wet to use.

Great video, nice professional work. Thanks. I'm considering a bedroom addition south fl. As well as rebars into the existing house what other things would be different to this process for the foundation depth etc?.

great video, well described. Useful. Can’t find a contractor for 253 sq ft closet addition. Should I try it myself? Watched this old house for an education. Rather not. Jp Palos Verdes

I wish I had your skill set for concrete.

If the building was built of masonry how thick would you make that outer band of concrete? Or would you do something different all together.

looks great as always... what would be the cost to dig out a 1 car garage and repour

Did you have to cover the copper pipe where it comes through the slab and did you have to anchor/epoxy the rebar into the slab where it meets the house?

So why are there no reinforcing elements placed under the concrete in this case, but rather just the plastic layer? Won't the slab's crack resistance be compromised? Trying to learn how to do a small shed foundation DIY, but all the other videos I have seen have included some sort of metal reinforcement underneath. Thanks for the helpful videos. Learning a lot from them!

With this being a room addition, shouldn't you tie rebar into the existing foundation? Will the slab not shift indepently from the house, potentially causing gaps with the new construction? I'm doing an addon this summer and any info would be helpful. PS I also live in the midwest, where we have big temperature swings, slabs are obviously done slightly different up here. Thanks, love the vids!

Type K is the thickest copper pipe you can get

nice job David when will you start to teach at the school

Hello, as a Mixer driver in Phoenix for 25 years you do things a little different in CA, I was wondering why you do not tamp the concrete bringing the creamy cement to the top? Also I would say 99.99% of driveways and all flatwork here in Phoenix they don't use rebar just concrete over ABC (sand & rock), and even then almost never do they compact the ABC. Any comments? Thank you and good work.

Great videos! Question for you, if your foundations has weep holes but you want to add a concrete walkway in that same area, is it bad that I’d be covering some of those weep holes?

Hi, I'm a novice at most of this. I have a couple of questions. So I'm building a mother in law suite with a bathroom that's about 40 feet away from the house. I have been puzzled as to how I can get water to the new structure. I seen that you stuck the copper directly into the ground and said that you used a 10 mil tape where it came out of the concrete, any specific brand for that tape? How long would the copper last underground, your thoughts on CPVC? How deep should I put the line/run into the ground and would imbedding it sand make it safer for the line? I've gotten mixed feedback on what to go with, hearing from some people that copper will corrode underground creating pinholes or the joints won't hold because it's exposed to the elements. Would taping the whole run if I go with copper make it last longer or at least the soildered joints? I want to go with copper since I heard that CPVC can become brittle within 15 years. I also have an electrical line that's 18 inches deep(South Florida Code) into the ground going to the building. How far away should I stay from the electrical line? Lastly there is also Type K pipe which isn't as common, from what I understand it features corrosion-resistant copper construction that has the thickest wall section of the three types of pressure rated tubing(K,L, & M) and is commonly used for deep underground burial; it's letter marking color is green and it sometimes has a plastic (polyethylene) sleeve. It's also used for gas line when buried I think.

My neighbor did a concrete room addition and now there is a big crack between the new room concrete floor and old concrete in the house. My question when adding a new room should you drill in some iron bars into old concrete to new concrete floor to keep it from separating?

I always solder my threaded fittings and then install them

Do you have a part 2 and then to finish of this sunroom ? Please 👍👍👍

I have never seen a slab for an addition to a home without a footer. Was there a permit for this? Can you really build an addition to a home on a slab of concrete with no footing in the State of California? Also isn't the footing supposed to have gravel stone added in the perimeter area for drainage purposes? This video has me perplexed.

you do awsome work putting a concrete deck next to asphalt driveway wondering how to bond them together anchors might tear up asphalt thinking of bonding agent? thanks

Just wanted to thank you for your videos. I have just recently started working as an apprentice and am beggining to get used to it and getting the hang of things. I see that you guys use heavy equipment and i am beggining to use the backhoe and skidsteer do you think that i should get certified and if so do you know any online courses that i can pay for.

Great video. Can you pour a driveway over grass and what happens if you do?

Hey did you use expansion joints against the house? I think you should have used foam around piping instead of just tape as well. Also what is the name of that copper fitting on the other side?

Hello! About 3 years ago my husband build a room addition in our backyard on concrete foundation. From the very beginning the room has had a very distinctive smell that hasn't gone away. Any idea where the smell might be coming from? At first we thought maybe it was the laminate floor and paint and with time the smell would go away. But here we are 3 years later and the smell still hanging around.

Mr. Odell how do you charge the rebar? By linear foot? Or square foot? Because is averaging $3-$5 square foot for concrete, but adding rebar is would be more.

great videos. was just curious why no expansion lines were cut into concrete?

Nice

👍👍

Great job 👍 but I'm curious to see how did the room come out

And....what about the specialty solder you used for this below-grade sweatwork?

@2:26 it looks like a worker took a minute to sip some water but that's time-lapse so that was actually five days

Love your videos. Where are you located? Would love to get a quote.

after the job is complete what do you do with the extra cement? I see you usually fill a wheelbarrow for touch-ups, low spots.etc...

So I have a shed on my property with a 2 foot brick foundation around the whole bottom perimeter that extends in the ground about a foot. The floors are still dirt, however. Could I pour a slab just straight in the center of the brick with fiber mesh underneath, or doi need to connect the new slab to the existing foundation brick somehow? Not sure what to do there. Thanks a lot.

I forgot to ask something else. I'm in South Florida and where I will be making an additional slab it's mostly sand and dust. Should I place a layer of gravel and concrete sand to make the base of the foundations more solid?

Nice! ....13

Do u need vents for this new addition

Watched.
