Brick work DPC to Blocks

[da3533]

Hello

currently, I am building a wall to replace my garage door.

I want to know the block name to use when ordering my materials...

I will use engineer bricks on my foundation for my garage, around 3 courses high. It will be a double brick wall with no gaps in between as i will be insulating the insides of the room....

Once the engineer bricks have been laid up to the DPC level, I want to be to use concrete blocks but enough width to sit on a double brick wall, what is the name of this block. It needs to be a good height, too, .. Is it a 9-inch block?


Thanks

I am a but confused, why do you want a solid 9" wall to infill the garage door?


in general terms a standard concrete block is 440 x 215 x 100 so if you want to use a black to cover the width of a double wall you just lay them flat as a standard metric brick is 215mm long

i want a 9 inch solid wall because it will match the existing wall, which is 9 inch. if i put a gap for insulation between the bricks, it will stick out from inside the garage. so by having a solid wall, i can put pir insulation from inside the wall.

You need to check if there's a foundation, you can't put a couple of tons of concrete blocks on top of a floor slab.

There are hollow dense 215mm wide concrete blocks available, but are zero fun to lay and rubbish to fix to or fill. Most brickies would prefer to lay two leaves of 100mm blocks, laid as a 215mm thick wall.

Are you rendering the wall afterwards?

Hi
Yes rendering the wall too…
The merchant said I need a 9inch block… but 9inch as in 9inch wide, where’s the dimension?

A builder just advised you to build two leaves.....

A nine inch block and a fork lift!

Build it in two 100mm leafs, with steel ties to hold them both together. Lightweight concrete 3.5N. Do not buy the heavy 7N blocks.

Oh I undetand. But it’s only 1m high and 1.44m wide…..

11 9" blocks too many.

What's the difference between building two 4" walls and one 9" one? You'll still end up with a 9" thick lump of concrete either way.

I'd suggest that laying the blocks down would be stronger, and not reliant on ties to hold it together.

Glad to hear it's got a foundation! Hopefully tied into the existing foundations. At the risk of stating the bleeding obvious, the blockwork needs to be very well tied into the side walls.

11 is too many?
How?

Each weigh 14kg. 154kg total weight on a 1m foundation ?

Do you know the name of the wall starters for these blocks?

215mm blocks are awful to handle, horrible to work with, hideous to cut, slow to lay and crap to fix to (hollows). I'd run a mile form any job requiring them, even if I was starving. It's great that you think they are better though.
