How would you repair this wall?

[johnny2007]

I've always used polystyrene to close the cavity and then a levelled piece of plasterboard stuck with plasterboard adhesive.
All gaps filled with plasterboard adhesive.
Is there a new way of doing it?
Maybe a new product, different ideas and/or better way to do it without taking bricks out and rebuild the corners?
Any suggestion welcome.
Thanks.

I usually board it
… sometimes I
Will build a bit of stud wall on the end
So
I get a nice Finnish then fill the brick with mortar… depending where it’s going you may need fire resistant board… that said I have been using cement board a fair
Bit recently

Thanks.
Can cement boards be plastered?

 

[Jake2021]

I’ve never
Had a issue, I just tend to
Do a couple of coats of pva then skim
It, there may be a plaster who might come along to reply and have a different answer but as I say never had a issue over the years it’s been available
Thanks
Jake

If it was my house I'd tooth it out and rebuild it in brickwork.

That's what I want to avoid at all costs.
It's not something that will be visible once plastered.
Thanks anyway.

If it was my house, I'd probably leave it for a few years and put it on the to-do list.

Is it your house or a customers?

If it's structurally sound, use expanding foam.

Depends what the payment situation is like.

To make the corner square?

 

[johnny2007]

Just seen that sts construction board can be plastered over and are available at wickes.
Easy enough.
Anything to suggest/add?
Thanks.

To make the corner square?

Yeah. Squirt it in, then cut it square.

I think it's great for corners like that, where there are lots of loose bricks, it really grabs and holds them, and then is easy to form.

I think it's great for corners like that, where there are lots of loose bricks, it really grabs and holds them, and then is easy to form.

But it's not strong enough for a high traffic area.
I use it to plug holes high up walls where nobody will ever touch it, the classic is redundant extractor fan holes in kitchens.
But in those corners i surely need something more solid.
The walls are sound and strong.
I've usually done this sort of work with plasterboard and plasterboard adhesive, I was looking for a stronger solution.
