Hiding TV cables in solid wall

I just chased mine into the brickwork, put a double socket in behind the TV on one side, then did aerial, hdmi, optical audio, two ethernets into a back box behind the TV (AV receiver in unit under telly)
Not worried about future proofing as assuming hdmi will be around for years and I'm not into replacing the telly every couple of years, the AV amp manages all the sources so can have up to 6 into the single hdmi for the TV, did all mine wwit euro faceplates...
 
I'd have thought it would lose a lot of structural rigidity due to the water in the plaster, which would then have a knock-on effect on the surface of the wall?

You used cardboard for that? I'm not sure what to make of that - walk me through what you did and how you did it?

Cut out a large portion of the existing plasterboard wall to expose the block-work, channeled out the required channel in the block-work large enough for the cables (and their ends to pass through). Formed a square cardboard tube to place it into the channel to provide a smooth surface to pass the cables through rather than trying to pass up/down against the bare block-work. Once in place the area was recovered in plasterboard and then the wall/area was re-plastered.

I originally did similar 13 years ago when I moved into this house and last year when I stripped the room down completely for a complete redecorate the cardboard in the wall was as it was when it went in. This isn't providing any structural rigidity as its purely there to form a smooth surface to pass the cables along. No wet plaster/mix directly on it as it is covered with plasterboard.

From what?!?!? It's a HDMI cable in there, do you expect it to suddenly combust? So what about the millions of people that probably have HDMI, other AV cables and power cables trailing across their carpets, surely that would be a bigger risk?
 
I think the answer is that there is nothing "designed" specifically to be buried in a wall for this purpose. You just buy some trunking (usually plastic) from the usual DIY stores or electrical/plumbing stores and use that. Chase the wall out using a proper tool. If you go on avforums there's hundreds of threads of this kind of thing.
 
Right then. 50mm plastic trunking + 47mm backboxes = done and dusted. Just needs plastering over.

I have discovered a previously hidden single socket in another wall that I could use (electric already running to it) but it is crazily deep in the wall... having pulled it out, I need to fill some of that hole in order to mount a backbox at a usable depth.

What should I use to fill said hole, that will allow me to screw a backbox into it?
 
Ive got to do the same as you.

Solid wall.

Im going to chase in a 50mm flexible conduit using thin metal straps to secure, screwed into the existing concrete block to exit behind my tv with a brushed faceplate and below where my av equipment is.

Purely for signal - 2x 8k HDMI 2.1 to future proof and in case any fails in the future and also 2x network cables - again in case one fails.

The 50mm flexible conduit will be wide enough to fish new cables through in case i need to add anything in the future.

For power im going to add 2x twin sockets behind tv in a separate run.

Should be nice and tidy and adequate to future proof/replace.

I hope this info is what you're looking for.
 
Thread resurrection...

If you're putting in 50mm conduit, how do you get it to neatly terminate into a backbox (for use of holding a brush plate)?
 
Yeah, I think it will be hidden so doesn't need to be perfect. Though its nice to aim for perfection.

Just having a little read... Your not suppose to chase more than 1/3 of the width of the brick, 50mm (which is nice for fitting cables) would be about 1/2 the brick width.
