This is a solid plastered block that’s the finish if I was using packers and drywall I would run the cable behind the drywall, however this install would work with direct stick drywall just use over length screws to fix the socket outlet.

It’s concrete pump mix with a 10mm aggregate, low slump, 20Mpa.

Problem is keeping the block there it will get blown out by the conc most of the retro cutting is in the block anyhow which is soft

Nothing like a big F up happens all the time most are fixable but a lot are not

LMAO 😂💦 I'm always very wary of other Tradesman who use the words , Easy and Perfect 👍

No that’s not a good idea, it’s better to put some conduit in and run the wire inside it, you don’t have to finish with an electrical box, just core drill a 65mm hole 50mm deep over the conduit, break out the core and cut the conduit back then screw the switch or plug straight back to the wall

@@hobsonproject So, run the conduit between courses of the blocks , or another way? Maybe down the wall from the top? I have a bit of experience of blockwork from working with my cousin many moons ago, but I don't see how conduit would come down the wall from the top since I have to pour a single lintel. Hence, the clarification. I want the electrical outlets flush on the inside of the block wall with no drywall. Thanks!

@@da324 Basically run the conduit like you would run the steel reinforcing for the blocks. Conduit can be short to get the blocks over it and laid and then extend further up with a coupling, can run horizontally if needed to get into the right space, but just remember to use slow large radius bends to make pulling the cable easier. 👇 Conduit in block wall kzbin.info/www/bejne/npbGY2aFa9ybosUsi=dE8qkD-8XfZ7B6G0

@@hobsonproject Thank you!

Here’s how I get the conduit in the block wall 👉 kzbin.info/www/bejne/npbGY2aFa9ybosUsi=dE8qkD-8XfZ7B6G0

I have never known an electrician use this technique as they usually have someone else chase the conduit and cut the box then they or someone else install the conduit and connect the box then usually someone else mortar up the wall. I guess the end result is the same as my cast in method, just harder, at the end of the day I will install draw wire to make electricians life easy, as electricians like an easy life, and they will pull their wires and fix the socket. Also keeps my costs down.

@@hobsonproject LOL sounds about right - we electricians don’t like to get our hands dirty! I have to install 5 boxes in a 100-year old concrete kitchen wall. It will have 1X3 furring strips, so I won’t have to dig a chase for the wires. But I do need to sink the boxes. I was planning on just drilling a bunch of holes with rotary hammer - but your grinder technique is a great idea.

You could always core drill the recess for the socket 65mm say by 50mm deep , can dry core without too much dust and then no water slurry problems

Lot easier than cutting the whole wall for the conduit remember this is a block finish, no wall strapping.

yes I think it would have been a better option
