Mixing Bricks & Blocks

[tuckjointer]

Can anyone tell me if I am able to use an lbc facing brick in a concrete block wall.
I've built a small 2 story extension and on the first lift of blockwork I use a single course of lbc bricks to get to floor joist height. I have already layed the floor, built the second lift and put on the rafters. I am ready for the roof instpection and suddenly realise that I maybe shouldn't have mixed materials.
I live in bedfordshire uk.
Can anyone help as I am currently crapping it. The last thing I want is to be taking half my extension down.

internal leaf or external?

i'm assuming internal??

 

[tuckjointer]

It's the internal leaf of blockwork, the externl is all faceing brick.

 

[mikric]

Are they proper concrete blocks that you have used for the internal skin ???

 

[tuckjointer]

They're 3 newton dense concrete blocks by name, but they're not actually cast out of concrete.
They're a standard 3 newton building block, not a thermalite.

No problem.

Potentially a thermal bridge with different materials but as this is concrete and clay, then its minimal - even less of an issue if you are plasterboarding on dabs

In the old days, we would carefully brush some cement slurry on them to to blend them in, and hide them from the clerk of works

 

[mikric]

Oh dear this could cause you problems with a keen bco. Is it a self build project ?

 

[noseall]

to use a dense clay facing brick on the inner leaf is a bit of a boob.

you will not have to take anything down though.

individually, they may be a cold spot.

collectively, they will not account for much.

glue some insulation to them before dabbing the boards or applying the plaster.

Many thanks Woody, I'll sleep well tonite.

Yes it's a self build. More embaressing I'm a brcikie

 

[noseall]

we've ALL done it tuck.

use light weight coursing bricks in the future.

 

[mikric]

If you do get pulled about it and it starts to get a bit involved act innocent and say you phoned bc for advice ,and was told would be no problem, but you dont know who you spoke to of course

 

[tuckjointer]

Thanks for all the help lads.
If they spot the bricks I'll act dumb, I'm pretty good at that

Yes they are called in the trade "brickettes"
As said all brickys have done it, but its a no no now with building regs and NHBC due to cold spots
