Are those light breeze blocks strong enough to hold a TV?

[matt84]

Hi

I've got an internal wall that I want to mount a TV on however behind the plaster there are the light breeze blocks (the ones you could dig a hole into with a spoon) and I'm concerned they might not be suitable.

I know TVs are very light now and the bracket is secured at 4 points with wall fixings but is this going to be suitable to hold the weight?

Many thanks

If you can get to the back of the wall, you can bolt through the wall (with a mudguard washer under the nut) and plaster over the nuts at the back. Paint the nuts with undercoat before plastering to stop rust showing through, or use stainless steel bolts.

On the other side is a hall/staircase which hasn't been decorated yet so I could possibly drill through and come out just above the stairs then cover it up? Thanks
