How to repair a hole in Leca at wall opening?

[Lizzardo]

I don't know if this is the right section of the forum for my question, the moderator is welcome to move the thread if that's not the case.....

When I cast my garage slab, the plan was to have my facade meter cabinet located in the Carport, but due to issues with Eon's regulations, it has now been moved.
All that's left is the recess where the cables were supposed to come up, and I'm completely stuck on how to fix it.
I'd be very grateful for help, thoughts, and ideas

The cable that's left is my phone cable.

Should the pipes remain or are they also redundant? If everything is to be removed, then it's just a matter of cutting a suitably sized leca block and bricking it up. Otherwise, it's just a matter of filling with concrete or foaming it shut.

Should the pipes remain or are they unnecessary as well? If everything is to be removed, then it's just a matter of cutting a suitably sized leca-block and walling it in there. Otherwise, you could just fill it with concrete or foam it shut.

The only thing that should remain is the hose with the telecom cable shown in the picture. Foaming might be a good idea, it's a bit difficult to fill with concrete since you would have to build a mold and the space would be completely covered.

If it's only the black cable lying on the floor that needs to stay, then it's probably just a matter of clearing away the other stuff and cutting a leca block to fit. Then wet the sides and press mortar into the joints. I myself filled a narrow "window" (made with glass blocks) in the basement wall this way.

Otherwise, there are probably no major problems filling it with concrete. It's just about putting a masonite board on one side, pressing concrete, putting a masonite board on the other side, and then further filling with concrete from above.

But if foam sealant is OK, then that's easiest.

I think it's a bit strange to end the ground pipes in the ground. I would extend the ground pipes and run them up into the wall and then do a nice casting so I get a smooth floor where there is currently a hole. After that, one can choose to saw leca strips to place on either side of the pipes.

If it's only the black cable on the floor that needs to stay, then it's probably just a matter of clearing out the rest and sawing a leca-block to fit. Then you wet the sides and press mortar into the joints. I personally sealed a narrow "window" (made with glass blocks) in the basement wall this way.

Otherwise, there shouldn't be any major issues with filling with concrete. It's just a matter of placing a masonite board on one side, pressing in concrete, placing a masonite board on the other side, and then adding more concrete from above.

But if foam is OK, then that's the easiest.

Perhaps I was a bit unclear, it's the white hose going to the junction box that needs to stay. The black one goes to a cable reel

I find it a bit odd to terminate the ground pipes in the ground. I would extend the ground pipes and pull them up into the wall and then make a nice casting so I get a smooth floor where there's currently a hole. After that, you could choose to saw leca strips to place on either side of the pipes.

I have to defend myself by saying that I'm not the one who did it. But now the conditions are what they are, and you have to work from there

OK, saw a piece of leca that goes from the right edge and up to the pipe with the telephone cable. Clean out the hole from foam or whatever it is and make a smooth bed with mortar, place the leca block on it, and fill the gaps with mortar. That's probably what I would have chosen to do anyway.

Of course, that's how it is! If everything went as planned, life would be too simple! d^_^b

Now the slab is cast smooth, so tomorrow I'll drill out a lecablock and split it.
Thanks for help/suggestions
