Section through a Brick Veneer, Slab on ground Building Part 2

Summary

In this video, the construction process of a brick veneer slab-on-ground structure continues with the brickwork phase. After completing the roof, including tiles and fascia, attention shifts to the ground level. Bricklayers lay the first row of bricks, allowing for the installation of termite protection using crushed granite or stainless steel mesh. A DPC or flashing is integrated to direct water away through weep holes. Brickwork progresses with veneer ties every fourth course to secure the structure. Windows are embedded with flashing to prevent water ingress. The eaves are framed out, and the interior is finished with plasterboard, cornices, and skirting. The video concludes with the exterior's final touches and landscaping, ensuring the building's moisture protection is intact.

🏗️ Brick Veneer Construction Process

This paragraph describes the process of constructing a brick veneer structure on a slab on ground foundation. It begins with the completion of the slab and the wall frame, followed by the installation of the roof tiles and fascia. The focus then shifts to the brickwork, which is typically started after the roof work is completed to avoid safety hazards. The bricklayers lay the first row of bricks, allowing for the incorporation of termite protection measures such as a crushed granite system or a termi mesh system. The paragraph also discusses the installation of a DPC or flashing to manage water runoff and the creation of weep holes for moisture control. The importance of veneer ties to secure the brickwork to the timber frame is highlighted, along with the correct placement of windows and flashings to prevent water ingress.

🛠️ Finishing Touches and Interior Lining

The second paragraph details the final stages of the brick veneer construction, starting with the installation of the brick sill, which is cut at an angle and secured with a thick bed of mortar. A rubber flashing is attached to the window to ensure water runoff is directed away from the structure. The eave line is then installed with timber supports and soffit bearers to secure the eave sheeting. The paragraph explains the use of quad molds to finish the exterior, followed by the interior work which includes the application of plasterboard, ceiling installation, and the addition of cornices. The finishing touches involve installing window architraves and skirting boards. The paragraph concludes with the importance of landscaping and maintaining the integrity of the moisture barrier to prevent moisture penetration.

Keywords

💡Slab on ground

A 'slab on ground' refers to a type of construction where the concrete slab is poured directly on the ground, serving as the floor of the building. In the video's context, the slab is the foundation upon which the brick veneer structure is built, and it is crucial for the stability and durability of the entire construction.

💡Brick veneer

Brick veneer is a non-load bearing brick layer applied to the exterior of a building, primarily for aesthetic purposes. It is not structurally integral to the building's support but adds a decorative and protective layer. In the video, the brick veneer is applied after the structural elements are in place.

💡Wall frame

The 'wall frame' is the structural framework of a wall, typically made of timber or steel, which provides the shape and support for the wall. In the script, the wall frame is mentioned as being built before the brick veneer is applied, indicating its importance in the construction process.

💡Trusses

Trusses are pre-fabricated structural components used to create the roof or bridge-like spans in construction. They are crucial for distributing loads and providing support. In the video, trusses are installed on the slab and are part of the preparation for the roof tiling.

💡Sisilation

Sisilation, or more commonly spelled 'insulation', is a material used to reduce the transfer of heat, cold, or sound. In the context of the video, insulation is placed on the roof to prevent heat transfer and improve energy efficiency, with the script mentioning its placement before the tiles.

💡Fascia

Fascia is a horizontal board that trims the edge of a roof, covering the lower edge of the roof structure. It is important for both aesthetics and protecting the roof from weather elements. The script mentions the fascia being installed as part of the roof construction.

💡Termite protection

Termite protection involves measures taken to prevent termites from damaging a building. In the video, termite protection is achieved by using materials like crushed granite (referred to as 'granite guard') or termi mesh, which are placed in the cavity of the wall to deter termites.

💡DPC (Damp Proof Course)

A Damp Proof Course (DPC) is a barrier that prevents moisture from rising through a wall. It is typically a layer of waterproof material. In the script, a DPC or flashing is mentioned as part of the brickwork to direct any water that gets into the cavity away from the building.

💡Veneer ties

Veneer ties are metal straps or ties that connect the brick veneer to the structural frame of the building, ensuring stability and preventing separation. The script specifies that they should be installed every fourth course of brickwork and sloped upwards to direct water away from the building.

💡Eave

An 'eave' is the lower edge of a roof that extends beyond the side of a house, providing protection from the weather. In the video, the eave is framed out with timber and is an essential part of the roofing process, with the script detailing its construction and finishing.

💡Plasterboard

Plasterboard, also known as drywall, is a panel made of gypsum plaster pressed between two thick sheets of paper. It is used for interior walls and ceilings. In the script, plasterboard is mentioned as part of the building's interior finishing, applied after the brickwork and other exterior elements are completed.

Transcripts

G'day and Welcome back to Buildsum and

As you may remember from the last video

We have been working on a slab on ground brick veneer structure and in the last video

We got the slab in we've got our

wall fame built trusses on

We put the sisilation on and we've got the tiles and the on the roof and the Fascia is in there as well

So now we're ready to come back down to the ground and start to build up the brickwork now

Realistically once your wall has been constructed you could

Start to lay the bricks

But a lot of job sites they wait until the roofs on and the guys are finished working on the roof

Until they get the bricklayers started otherwise you've got Tilers

working above bricklayers, and just gets messy as far as work health and safety goes, so

We've got the tiles on now. We're going to go back down to the bottom of the wall and

Have a look so what we've done it in the meantime. Why we were doing the roof?

The Bricklayers have came in and they've put in the first row of bricks

and what this does it gives us the opportunity to put in our termite protection, so

Depending on what system. You're going to use you can use a crushed granite system

Commonly called granite guard, so the cavity is just filled up with the granite guard material

Or you can use a termi mesh system

or a stainless steel mesh

so this is just a steel mesh that gets stuck to the concrete without what they call a Parge which is a

cement based adhesive

it also get tacked gets tacked on there with concrete nails or Mickey pins and

It gets laid into the bed of the mortar of the bricks

also this layer you're going to put in your

DPC or a flashing

Okay, so it's going to run from

the

Brickwork sorry from the bottom plate into the Brickwork and

What that does is any water that runs down

Will go through your bricks into your into the cavity will run down the back of the brick and then it will come out

Through what they call

the weep holes

so

Any water gets in behind the Brickwork across the bricks are porous it will eventually work its way through the bricks

it will run down the back of the brick it will hit this flashing and

then it will run out through these weep holes which are just the

Perp of the brick this is the perp is left out so we create that weep hole that lets the water come back out

Okay, and then we can start of course before we get too much brick in but I put our window in windows have

a flashing and

We should also put in our sarking or sisilation as well

All right

the sisilation actually runs down and

Laps over the top of the flashing so again any moisture that was to get through the brickwork and across

The cavity would hit the sisilation run down onto the flashing out through the weep holes

Okay, we're going to start our Brickwork every fourth layer of Brickwork we need to put in what we called veneer ties

So these actually tie the brickwork to the timber frame the video ties should be sloped up

Slightly so this end

should be higher than this end and

What that does it just means that if any water hits it it's going to run back towards the Brickwork

and not back into your building, so

they should be actually slide up a little bit

Okay, so as I said every fourth course and they should be the last rows should be at least two

courses of Brickwork down from the Top

Okay, so there's couple close there because I didn't want to have them too close to the top of the wall

And then you can put your brickwork in

Okay, so your bricklayers the Brickwork they lay that up to a level which is

given to them by the carpenter, and it should be the same level as the

recess in the fibro so that the eave will go in show that and sec

Okay, you'll notice

That when the bricklayers lay the bricks they leave

underneath the Window low by about two courses and

They embed the flashing into the wall

So it's all bedded in and any water that gets

through the window or down inside the brick is not actually going to run out into or back into the building

the brick sill goes in

okay, the brick sill was cut they cut this our angle on the bricks they put a

fairly thick bed of mortar normally they lay

one bed first let it dry

And they more let's stick down with the second bed

to give you the brick sill on that just lets any water run off. You can see there the little rubber

fFlashing that's attached to the window is also. Make sure it sticks out over the top of your bricks

Then go up to the eave and you can see we've put in the eave line

I've got a

timber running along the inside of the brick and also the back of the window so we can nail our quad up to it

I have

bearers soffit bearers running

Every off the end of every truss

so that we can nail our eave sheet in the center and

That's all supported on droppers

Which are generally just off cuts of tile batten that dropped down from the rafter or the truss itself

So once the eaves framed out you can put in your soffit sheet

and

To finish that off which is still going to have a gap here

You put in a quad mold and that finishes that off it may return to the window depends what you want to do there

So thats the outside done. We can then go inside and

Put on our plasterboard

Or whatever our lining happens to be

our ceiling

Our cornice s to finish off the corner

You have a window in with our reveal finishing flush to the plasterboard so we can put an architrave around

our window and

Down on the floor we can put in our skirting

Okay, and as I said at start we end of the job we would landscape

Hopefully this membrane still pretty much intact, so it can actually do its job. Not allow any moisture to pass through here

and

We're done

so that is a
