g'day and welcome back to build some and
today I want to show you a double brick
construction building without a timber
for so as you can see we're starting
starting out very similar to the other
videos that have done on these
construction methods however for the
observant among you you'll notice that
this footing the strip footing here is a
lot wider than the other ones and that's
because instead of just sitting one skin
a brick click on it
of course it's double brick construction
of now but it's it - it's going to be
quick on that footing so that's a little
bit wider to start with so that we can
get both skins a bit of course a strip
footing requires reinforcement and again
for the absorbent you'll notice I've now
got four bars across here instead of
three because of the extra width of the
footing and again that could be just
strap plain old bars or it could be a
four bar trench measure that's used
again it's spaced off the side of the
trench to allow for your cover and it's
sitting on bar chairs so I stopped
touching the bottom of the trench and
once that's in place and inspected we
can pour the concrete in there again
keeping it just below the ground line so
I can cover it up liner and we can pour
our blob footing to spot concrete in
there now the second or the big biggest
change if you like is the dwarf wall is
now our two skins brickwork still has
our vents in it
however the back skin don't need to put
the physical vent in there can just
leave that open so the airflow can pass
through and you'll also notice that in
the cavity the bottom half here we've
actually filled that in with mortar and
we've sloped that off so that any water
that does get into this area will run
down here and out through the weep hole
here
that way I still have an engaged pier on
the back of the dwarf wall just holding
up this skin and brickwork I'll show you
in a minute how I connected to that one
and we have our engaged pier to take it
up here as in joist as per normal we
have our damp-proof course this one's
wide enough to cover both walls also
fall out engage pier and our isolated
pier and we have our end cap as well and
again this one is wide enough to cover
both both walls of course our bearer and
our joists now this time we don't need a
double joist on the outside because the
wall is not sitting on the floor this is
just taking the floor so if you put a
sheet or platform floor the wall is
actually going to come up the inside
it'll be brick and we won't need before
to carry any of our wall loads at all on
the outside we can start to bring our
brickwork up and as I said we're gonna
tie the walls together with these things
is called Moore's ties you can see
there's a little divot a little bend in
the middle so that any water wants to
cross the cavity it will get to that
little divot and then drop off and then
I'll tie these two courses a brick work
together they can also be used to tie
you engage pier back to your main wall
as well quite often so there are Moore's
tie
and then we're going to continue the
brickwork up so that's the first part of
our double brick construction timber for
building in the next video I'll show you
more about the wall and how we tie the
roofing
