okay we keep talking about a lot of

different types of walls and one of the

problems is heat right just take way too

much for granted for the average

listener in understanding what it is

we're talking about so we talked a lot

about a hollow wall okay this would be a

hollow wall okay when you look down in

it there's nothing there now granted if

we were tying this into a footing or

foundation the bottom 12 inches would be

fort solid and there would be J bar or

different there's ten different ways to

tie this into the footing and foundation

itself and so but other than that the

wall we want to the objective is if we

can keep it Hollow by going with a

stronger wall stronger tensile strength

stronger structural strength using

synthetic fiber using plasticizers just

ways to strengthen the wall and the

answer is yes we can I mean there are

walls that can be that there's there's

some walls that are constructed that are

printed with 500 psi I can front Tran

with 3000 psi 5,000 psi standard tight

best mortar mix is around 2,500 psi and

so there from there we can start adding

a myriad of different magnetism

if we want a cantilever then we're gonna

have you know liquid adhesives there's

powder adhesives so cantilever but if

every pass I want to go like this and

this and this in addition to that

there's you know this there's so many

different types of products and

additives it can be added and not only

that I mean this is this is traditional

this is rebar I'm gonna drop it on the

floor are you ready okay okay this is

basalt rebar 30% stronger okay

I can carry 50 of these in my shoulder

upstairs you're never gonna do

traditional number four steel rebar

there's so many new technologies that

just nobody is using and it's just

ridiculous to me I can't even I can't

fathom it at all no number Anna this is

available at every home people and you

know dater bar isn't but it's a much

better crowd much stronger problem ok

Reeve art is just disastrous to concrete

it swells it rusts this is the reason

that in many cases concrete is you know

a 50-year life this is what the one of

the main reasons because this is how you

structurally strengthen concrete with

rebar number four rebar rebar verticals

horizontals all tied in and poured but

it's also one of the worst enemies to

concrete most people don't realize that

so it gives it tensile strength this

concrete traditionally does not have but

you can start using different types of

fibers and you can get concrete that is

as strong as she walks be they built

concrete that was 50,000 psi back in the

fifties that's just off the chart for

most people unless they're in

post-tension construction or they're

building high-rise

you know you talk to the average

residential contractor about 50,000 psi

concrete new cities like BX okay they

don't believe it so one of the first

conversations need to happen is what

kind of a wall structure do we want to

have guys ideally you want to have a

hollow wall

okay it's over here move some stuff

around for you this would be a wall with

internal mortar support was so and I'm

talking about internal mortar support

I'm talking about a wall or we use the

mortar itself to give additional

strength

typically you'd see this on an exterior

wall but it's not necessary it really

gets back to what Nick's are we starting

with okay people call us all the time

and start asking us you know you know

what's the structural strength plus the

tensile strength if you can my hell

there's there's a thousand different

mixes that can be used okay but if you

just don't want to deal with the

building department at all the very best

thing to do is build yourself a wall

print it that looks like a cinder block

put your rebar in it pour a solid full

of concrete and voila you're good that

that'll pass anywhere and my stronger I

mean yesterday I took out a Glock 40 cow

Glock 20 to 40 Cal shot a couple rounds

into one of our walls just to see what

it would look like just amazing sure

didn't know a cinder block and see what

you get

blows the thing apart okay there's not

even not even close to the structural

strength of a wall it is monolithic

board using three to five thousand psi

joining them back to some of the basics

if I can keep a hollow wall then I can

run electrical through the wall

I can run plumbing okay drop it down in

so it's going to lower all my cost for

straw

excuse me for electrical and plumbing

but if I design up exterior wall that

has internal water support like this you

can see it becomes a challenge now we

gotta come in through the top plate

eight foot up drill holes drop them in

to try and get our electrical and

plumbing where it needs to be so if I

can avoid this guys you want to avoid it

okay look at how it's going to impact

all your other trades electrical

plumbing your your venting your low

voltage for security and everything else

it impacts everything if I can stay

Hollow I want to stay hollow the answer

is you can stay Hollow but this depends

on how afraid you and your structural

engineer is of the building department

and the sad thing about that is if your

structural engineer does its job the

building department does not have the

legal right to say no all they can do is

say I don't understand can you please

explain it to me

okay but if we want to coward and

sometimes that's the smartest way to go

that's the smartest marketing approach

is give them what they understand okay

baby steps so if you have internal motor

support you want at this you want you

want this you know every 12 inches you

want the radius of these to be every 24

inches that is what your engineer will

determine once he gets the lab results

of the mix you intend to use and then

you have to use that mix okay but there

are a myriad of different mixes there's

two there's 50 different types of data -

if you can put in your mixes it changed

the cost of your mix so something like

this we can print this for about a half

a cent if you begin to start getting

into mixes with synthetic fiber and all

these different ad

they're bad kids your mcbusted and go up

but your labor costs for all these other

trades we can go down anyway

I hope that answers a few questions

about the difference in walls hollow

wall wall with internal mortar support

okay turn more sport that will work in

some places and others depending on the

mixture using you're gonna have to add

the rebar as well feel like solid you

see the disadvantages in a wall like

this you see the advantages in a wall

like this and so I hope that answers

some of the questions for you we keep

trying to do a better job pitches are

Kish Kish kion is doing all my videos

for us now you don't like the old ones

and the way we were doing things so you

can't tell that I'm smiling so you'll

see a lot better quality and a lot more

videos out there that's all she's doing

every day just shooting videos making

sense of all of this you know from our

perspective would take too much for

granted we know too much we'll be doing

this for three years

we understand you may have only known

about concrete training for the last 24

hours

and so she's been very valuable coming

in saying I have no clue what you're

talking about here we're like what you

mean

wall the corner support hollow up but

yeah let's go do a video good let's

explain it the people make sure they

know it so she's very valuable than what

we're doing here if you got some videos

and ideas if you would like to see stuff

that we haven't shown you okay send her

an email kis kis h @ Mudbox comm so I'm

sure she'll make that available to you

anyway let her know what you need let

her know what you'd like to see we'll

put it online for anyone Thanks
