How to lay these???

I was looking at 9" cavity blocks and came on these ones.

How would these be laid? What would you use at the end of each row?

I think the pictures wrong compare the size and dimensions to the 6 inch cavity block http://mccarthystramore.ie/product/6-concrete-cavity-block/

Suspect each 9 inch block will have 2 cavities?

I used that picture as an illistration. My local builders merchant has 9" blocks shaped liked the ones in that picture. Just wandered if they were laid on the flat what you'd use at end of the row?

No idea but standard 9" cavity blocks seem to look like this: https://www.build4less.ie/cavity-block-9-440mm-x-215mm-x-215mm.html

Maybe what you saw is some sort of half block or handy unit for making up the bond in places. I built a shed out of 9" cavity blocks, worked out OK for the straightforward sections but found them a bit of a pain if they had to be cut. Really need a selection of bricks and soaps to fit in here and there.

I'm wondering if they have to laid upright?

Or are they a final top layer if you are laying a hollow block wall?

Think you guys are reading too much into the question i think he is simply asking what way they are stacked ...

OP: they are laid with the hole going from top to bottom. blocks on row above straddled between 2 blocks below.

You can buy half blocks (sometimes known as "footballs") for the end of the course, or you can cut them in half as mentioned above..

What I am reading is that the picture (which may have been stretched by mistake) in the OP's first post is a single cell double height block, I know that sounds daft but I am trying to understand what the OP is referring to and it seems to be the picture rather than the dimensions that go with it.

jack of all

Cavity blocks come as one or two hollows- two (vertical) hollows used for bulk of wall, single (horizontal) hollow type used to cap off a wall and off course the half hollow blocks mentioned above which are 215 x 215 x 215.
