His customers very obviously have more money than a lot of people, though. I mean this video is a perfect example. A ten car collector garage. You compare the cost of this foundation versus the average garage and I bet its about 5X the cost. Once you include the cost of the actual garage I bet its more like 10-20X the price of the average garage...Sure, it would be great if everyone could afford something like this but that isnt the reality. This quality of work is simply a luxury that most of us cannot afford.

Doing thing "right"? Shit, if this is doing things right, who the hell can afford it? Not even 1/4 of America.

Do you get anxiety from the thought of job-searching? With credentials like that, I'd imagine you never had a problem getting hired.

@@Tubeytime hahahaha

Nelson Rockwood there are other factors. Foundation type controls the amount your slab and the rest of your structure moves. It's mostly due to moisture. Clayey soils will expand when wet and contract when dry (you can actually see the cracks in the surface during dry conditions). This changing in volume is what causes the foundations to move which will lead to cracks in the slab and walls etc. a stiffer footing system generally means less movement. Good drainage will also control footing movement. As will the presence of large trees and plants. (Avoid trees near the structure as they suck water out of the ground). Sands are not as reactive as clays and so do not often require such a stiff footing system. It also depends on what the structure above is going to be. Is it built from steel? Timber? Brick? Brick veneer? Articulated masonry? They move differently and some require stiffer footings. Also the bearing capacity of the soil will need to be taken into account. These are all reasons for why you should get an engineer involved from the start.

How do you ensure proper preparation for underreams “beams” before pouring the concrete

finally Matt wearing manly men jeans Bravo

I would like to know this as well.

Basement forms and concrete or basement with CMU block? Also what about ICF foundations? Couple different kinds of crawl space foundations as well....

Over engineered doesn't mean done right.

Nathan McIntosh Matt does high end work for customers who are more concerned about building it right than building it cheap. I know nothing about construction but I imagine a lot of it is referrals and such.

The act of building a 10 car garage for an assumed collector of assumed high-value automobiles, one that has a cantilever construction with ancillary living accommodations on its 2nd story, implies that the client is wealthy and that the home to which the addition is being added, is most likely valued in many multiples of the addition’s cost

MrEndzo it means its done better.

Who defines better? The builder or the client?

ACI 302 has more or less made it so a vapor barrier is now always required.

it keeps the humidity/water out of the concrete as to prevent it from hydro cycling which can cause cracking, especially in colder climates

I've never heard that phrase before "hydro cycling". It is just perfect. I am going to use that!

My guess is he would water down slab each day and replace plastic. I had same question.

Best practice is to use purpose-made concrete curing blankets that have a felt liner that holds moisture. Then you can add water as needed to keep the felt damp. You should try to keep the slab continuously moist - black plastic sheeting doesn't do that (although better than nothing - but not much - unless you are constantly checking to see if there is sufficient moisture - the problem is that the sheeting doesn't retain moisture and if there is any slope involved, the water runs off or ponds). Some put sprinklers on slabs but the amount of water required can be significant.

Lmao

Maybe if your building a runway

looks like it was a continuous pour

Robert Hawke I only really see post tension on larger buildings and a few retaining walls. But that could just be my experience.

Houston is SOUTH Texas with a different type soil. Less plasticity. Matt is based further north in the ' hill country'. Soil tends to have more clay which increases 'plasticity' . Like north Texas as well which the soil plays H . E. double sticks on a foundation due to typically very high plasticity.

I am a homebuilder here in North Texas. This type of foundation is engineered in a way that the gravel is not necessary. These types of slabs are very strong, but could always benefit from installing extra rebar.

If the foundation is designed and constructed properly, then piles are not needed.

He's building for Texas, not Minnesota. This wouldn't fly for Minnesota needing either a footing below 5 feet or 1.5" insulation panels all around and outside footings. Every jurisdiction is different. In Arizona, there are little to no codes, and you're at your own risk.

Erez Talshahar I am in Kentucky. I could understand if I were in Minnesota due to their extreme weather. But were in a green world. What's stronger, simpler and makes more sense doesn't have a place in the near future. The insulation has to break the slab at the inside of the wall here. Ruling out a single pour.

@@rumdigittyrum Thanks for sharing this. Seems like a good system. It essentially turns the entire slab into an engineered beam. I'd be worried about the cost of the proprietary system, though. It's all just injection molded plastic, but I'm sure it's not cheap.

I'm fairly certain to don't want to penetrate that slab as its a monolithic design to move as a unit

Based on the video, he thinks rebar reinforced slabs are a better choice for uniform strength across the entire slab.

I’m a builder in south Texas an the cable system relies on to many perfect Field conditions to make for a good slab. I have seen guys trying to pull cables standing on buckets with a heavy machine when the slab is 5 ft off the ground and it’s 100 degrees out and they skip a few. Timing also and the concrete dries at different rates in different Humidity situation’s. Just lots of steps for the cable to be missed or fail if not done properly . The savings is not ever 10%

gravel is only required per design, for this application the vapor barrier he shows does the job.

Depending on AHJ (Authority having jurisdiction), gravel is required to prevent water retention under slab.
