In south Florida they require vapor barriers and vertical dowels. Its cool to see how things are done under different codes

Hey Keith, Would love to see a final walk through on one of your homes if possible. Also when you do it maybe go over things you look for before you cut the final checks and turn over the keys to the owners. Keep up the videos they're a huge help!

Thanks Keith. Very timely and informative. Please video the pour.

This is great video, you're a great teacher. I got my start in residential home building this past year after transitions rom pre-fab and modular construction and learned so much from our subs more than my actual boss.

Glad to help. I will keep it up

Usually I do plumbing that is what I went to technical college for. The toilet stub outs I usually use 1 1/2"-2" of foam wrap that is about a 1/4" thick. Same style dirt in the box for the tub drains. Maybe they did have two pipes stubbed up for the island sink. Usually I have the clean out and sand tee on the drain side on the underground so on top out I don't get it mixed up. Plus on top it's going to get tested with other fittings any ways.

Well done.Even i can understand the process

Usually on jobs I have worked on the stem wall and some footings are poured first, then the slab. I have not seen many if any houses that the stem wall is not dug down lower than the ab for the slab as well as any footings.

Awesome!!!!! Thank you so much!!!

You bet!

That island sink should have a Boston Loop on the plumbing, which is two pipes coming out of the underground that go through slab. Two long turn 90°s, a Y on a horizontal underneath the dirt/ab, a vent tee underground, a Santee with a clean out under it on the drain side all 2" pipe except for the horizontal stub out in the Santee can be 1 1/2" or 2" pipe.

Thank you

WOW, No gravel under the slab, & no vapor barrier.

@HowToBuildYourOwnHome

We do have gravel, it's called chat, compacts super hard, kind of the go-to in this area, or road base. No vapor barrier as we are close to the river, we need to keep the concrete dry so water can stay in its place. I am not a fan of vapor barriers under concrete unless you have erosion issues in the soil that can affect the concrete, like in Vegas.

Great job this is the way to build a home I don't like the cable

Hey Yo Keith, I hope this finds you well.... 1st, You have THEEEE BEST clip I've found on slabs for my plans. And you answer questions too. I hope you can and will answer a couple for me, too. Scenario: I'm going to be constructing a VERY modest house after trucking in clay to raise the lot 1.5 meters and left to settle for one full year or two.... I want a single rectangular house about 5m × 15m (900 ft²). AND....I'm building in a rice village in Thailand. I also want a "ranch style" concrete patio all the way around with an extending roof. I want it to be 5 meters wide. Question: Should it be one giagantic slab 15m × 25 m ? Or should the slab be independent and patio slab just be poured up to the house slab? Lastly.... Finances are not going to be significantly different between 3,4,5 or 6 inchs of concrete. Is thicker always better? This part you don't need to know. Also all electrical will come from the rafters downward. The plumbing will be one bath and one kitchen sink going to a big catch containment that overflows to the municipality sewer system.... Thank you for the clip. I 👍 button

I love walk out Basements than a pad....

I agree

Thank you for the tip on burying the electrical conduit in the ground. I've seen folks that just lie them on top of the dirt prior to the foundation being poured. It makes sense that would cause a weakness. But what about running PEX tubes through the slab that are connected to the rebar, for radiant floor heating? Do those also weaken the slab?

@HowToBuildYourOwnHome

I would thicken the slab to at least 4 inches. As long as you have two inches of concrete coverage you should be fine.

Great video, as usual. What's your preference Keith, post tension or rebar?

REBAR

I've seen rebar chairs that were just pieces of concrete, seems like that works pretty well. Then you don't have to guess where it should be as you are pouring. Also when should underlayment be used? Moisture from the ground can suck up into the concrete and get to the rebar?

Really great videos Keith. I'm just about to start building for the first time and these are dynamite for me. I'm building with Interlocking Compressed Earth Block (like a cement stabilised Rammed-earth tongue and groove block system with a slurry mortar, so I should not need highly technical skills on laying the blocks), and making them myself, so if you have any advice I would love to hear it? I will also be using Cupolex plastic domes, which leaves an air cavity under the slab. This system is supposed to make the slab stronger and allows me to pump warm air from the ceiling back under the slab to aid winter heating. Do you know anything about this system?

Please send me info on it. It is basically acting as a thermal bridge. Creating a thermal bridge is going to be the big tech advance in all construction. They have already mastered this in windows, for the most part.

@@HowToBuildYourOwnHome Kieth, I'm not sure if you are asking for info on the Compressed Earth Block system or the Cupolex dome system, but here are both: So the Cupolex system you can see here: kzread.info/dash/bejne/YoxsqZiqqZWtktY.html For the ICEB system, I will use a batch mixer and hydraulic press which applies 20 tonne of pressure to make 2 blocks at a time, and about 35,000 blocks in 8 days. I calculated I can save $100,000 on this stage alone.

In my arid climate it's generally not called for. The only reason I can see installing this is if you had high ground water or greater moisture in the soil, or high alkali in the soil that can can erode concrete.

What do you mean by blowing out the footings with a blower? Is it not dirt? How are you using a blower to blow dirt around. To what end?

Are there any regulations about building a garage slab over a sewer line running through the property. For instance a garage slab spanning the width of a back yard with the sewer line running under under the slab and garage.

I never pour a slab without rebar. It does not stop the cracking, but it can limit the extent of any severe cracking or separation.

I’ve worked in construction on commercial properties for decades. I’ve seen slabs that didn’t have rebar imbedded in the concrete. There were potholes literally starting to form all over the place and one of the tilt up exterior walls was starting to separate from the rest of the building. If you don’t put rebar in your foundation you’re a class A Moron and you deserve to be separated from your money 😂

No and yes. No in the flat area and yes in the footings. No because it's hassle pouring and tripping over the rebar when you use chairs. We lift the rebar into place on the slab area as we go.
