You'd have to diamond cut/grind each one precisely and hope you hit a void perfectly every time, nigh impossible.What is preventing you using a dry lining box?
Can you describe this in more detail please Mike? I can't quite visualise how this works (the cells run horizontally), but it sounds like it would be usefull.Don't chase for the conduit/cable feed from above and below through the hollow block, just knock through each top and bottom with a long rod and yes I have done this as its common practice in countries that use the hollow block wall construction.
I thought that was enough detail, but I use a piece of reinforcing rod and a club hammer, according to how far up or down you need to go, it may be necessary to drill in an intermediate rodding point, you only have to go through the top and bottom of the block, bit of a pain to do, but not as much work afterwards to make good.Can you describe this in more detail please Mike?

I come across this type of blockwork fairly regularly. It seems like it was a popular material round here sometime in the 60s, usually used for the inner leaf of cavity walls, but also internal walls too. It's a pain to work with, particularly when it has only a thin coat of plaster covering it and you have to chase it out.
The cells run horizontally, so
