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
