How to fix this?

Hole in the wall that once had the dryer outlet fitted.

I have some of the original precast blocks and some suitable white cement + sand.

I'm just wondering best way to fill the hole. Just mortar or cut some chunks off the spare block? If just plain mortar, best way to stop it slumping out?

Thanks

can you not cut the block out and replace the thing no matter how you try to patch it it will always look patched

It's a large block and my spare is not big enough to fill.
However.....once we all get back to work I can go to the people who still make these blocks and get a whole one that fits.
TBH I hadn't really thought about replacing the whole block. I have a mortar line chisel for the SDS, that would make short work of getting it out.
Thanks!

In that case, might your spare be big enough to just cut away part of the large block as a replacement? I'm thinking angle grinder with stone disc and cut the large block out vertically top to bottom, just to the right of the hole? There would be no need for the section cut out to be the full depth of the block, just two or three inches deep would allow the hole to be covered.

if your skilled enough with cutting tools ect you really i need to take the face off the brick if you get my idea

i’d fill it with expanding foam.
trim it back 40mm below the surface after it’s set .
wet the hole and fill it with the white cement youve got.... wait a few hours and get the texture back with a sponge.

Great minds think alike!
I was thinking along those lines as well.
I was also thinking to make a horizontal cut just below the hole, that means I don't touch or go near the DPC.
Thanks, I think I have a handle on it!
