What is my wall made of? (TV bracket install)

[Pistachio]

I'm trying to install a tv wall bracket on an exterior wall. I was planning to run the cables behind the wall. I thought it was plasterboard framed on a brick wall but it definitely isn't! It is soft like plasterboard but I can push my padsaw in 90mm. Is it breeze block? The house is about 1980's

Any help appreciated!

Breezeblock

 

[Pistachio]

Damn. That's definitely not going to be strong enough

Should be with enough of the right fixings

 

[Pistachio]

I was just thinking what if I got long enough toggle fixings?

Yer needs bolt expanders

I'd use these mate

Problem being that the wall is soft, I can see them not going tight enough because the force will open the hole up.

I could be wrong though.

Na the wall is too soft for those to work I think. I can push my padsaw in it just leaning on it

 

[Ol’ Tarby]

Hmmmm sounds soft as f**k then

What I use at work is a two part resin which I use for studs, it's hard as fook, I use it for 16mm studs when I fit crash barriers.

Put up a stud wall over the breeze block?

I'd be worried if my wall was that soft !

Pop to you’re local builders merchants and get some resin fix. It’s in a single tube but 2 part.
Drill hole, clean out dust, cut some m12 bar. Pump in resin, push in bar, wait 30 mins and away you go.

It’ll be fine. Just make sure you get rid of the dust from drilling

 

[Ol’ Tarby]

You might be able to screw directly into them with the right type of screw/bolt?

 

[Pearce]

Are they not thermalite blocks ? If so you’ll be able to fix to that easy enuff with the correct fixing I’d be more worried that it looks like they’ve just papered over a block wall lol is there any plasterboard then plaster in front of the block ?

My TV is 50kg and fitted to an exterior wall via 4x M10 studs set in chemical resin. The wall is dot n dab onto breeze block.

Hilti do some good fixings,where you just drill a hole and screw directly into the brick work.


You can also buy the polyester resin in the smaller tubes now so it’ll fit a standard silicone gun. The studs aren’t cheap and it might be overkill for a light modern tv, but it’s definetly not coming off the wall lol

Thanks for all the suggestions. I like the resin idea. I've got some 8mm stud and nuts here. I'm still considering toggles though because if I get it in the cavity between the breeze block and brickwork there is no chance it will pull out.

@AlfaDan it is a 42inch plasma and I've got a bracket that pulls out from the wall so that it can sit at an angle, so the stronger the better!

Definetly Resin anchor if it comes off the wall, toggles would be useless

Thermolite lightweight blocks

I used these for a 42" plasma

I would fix a piece of ply to the wall with plenty of fixings then mount the telly bracket to that. I've not dealt with thermalite a lot, but know you can get special fixings for it. I've used resin a lot and it's good stuff. Just make sure you're prepared and have the holes drilled and cleaned out before you start using it. It sets hard in the nozzle after a few minutes of not using it.

This was my thoughts.

I Remember these breeze blocks from the 80s
When working on building sites
They were that soft you could virtually drill them with your finger
Made from compressed ash from the leftover s**t of a coal fired power station
They mixed the ash with water then compressed and dried them
f**king rubbish I’m still amazed a lot of these houses are standing
