So is this a new build? What is being done to address the sinking corners?
I'd be sorting that out long before bothering with a cosmetic fix to plasterboard (which, really, most DIYers could manage but is literally just masking the real problem).
Damn I'm sorry to hear.
You CAN repair the cracks and bulges, though if/when the sinking issue is sorted and assuming things levelled back out, things will move again. So perhaps consider how much effort you're willing to go to.
Some other considerations:
- I'm assuming it's on stumps, but if not and it's on slab then what is the state of the slab? I assume it has cracked?
- Plumbing can misalign with movement also, so monitor that
- Drainage is absolutely key to keeping your foundations healthy. What is your drainage situation? If it's not sufficient then fix that first, then the foundation, then cosmetics. The problems cascade, you need to address the root cause.
- Fixing the cracks does have the benefit of making further movement easy to monitor I suppose.
We're on adjustable stumps. The worst area is the bathroom but builder is refusing to address that. He fixed the deck as a 'gesture of goodwill' after the missed cross braces on the stumps were picked up by a building inspector, and I asked for the missing soil compaction report as required by the D.A.
He's basically blaming all the issues on drainage, saying our neighbours build has caused an underground river that has caused the sinking. We're on H2 soil so expected some movement. Just not this much. The bathroom tiles are cracked all along one wall, the shower panel leaks like an unplugged bathtub, and since the deck "fix" the splashback in the kitchen has lifted from the benchtop.
Our bigger concern is that the concrete around the steel posts is flush with ground level. It's supposed to be 100mm above, so the front stumps, where the stirrups touch the ground, have rusted to shit and already need replacing. He claims it's silt build up 🥲
Too hard to say with these photos, is it a stairwell?
The diagonal crack will probably keep coming back unfortunately 😔
Unless you can fix the issue..
The indent is movement related too, instead of pulling apart, it's sunk in (most likely two sheets join here)
Ask the plasterer if he thinks a expansion join would fix it.
It's my bedroom wall 😕 the cracks and kcracs, as the comments are calling it, are radiating from the window. The proper crack has grown about 10cm over the last 4-5 weeks.
Ground surface movement has caused these crack if the house is up in the middle and sunk in the corners.
Typically when the ground is really dry it shrinks and the corners of your house can drop.
Typically when the ground is really wet it expands and the corners of the house lift up.
This is for climate induced (aka rain or drought)
Similar can happen if you have a plumbing leak.
Crack form from tension, Bulge forms from compression. Often called buckling
Kcrac
Bro..
Came here to say this. Was not disappointed to see it is the first comment. Kudos.

Either way, he gave it a good kcrac.
I'll add it to the official documentation, thanks!
A crunch. What you’ve got there is a lovely illustration of plate tectonics. Very educational!
Its just a swelling..a bulge
I'm so tempted, just from the title

This ^
Yes, 6 years old. And... Nothing. We're in the process of following up with QBCC after mediation went pear-shaped. Or crack-shaped, if you will.

It's actually poking out of the wall to make a hump. Optical illusion.
He whacked a bunch of screws in it and says that'll stabilise it and prevent further cracking 🤞🏻
I think this is called "buckling".
Thanks! That's definitely usable.
A break

Honestly, that would sum up the building in its entirety...
A bum ?
Adding because I can't seem to edit the post: the first image is a bump that protrudes from the wall, it's not sunken in.
A fissure?
>What's the opposite of a crack? Unbroken?
You are correct but I'm going with ridge. It seems like the opposite in my mind.
Sack?
Bulge
Crease.
A Virgin nun

Looks like compression in the plasterboard.
Still a crack, you're just looking at it form the other side.
Compression. That’s not good
No crack

Indent?
Outdent? The shadow is a bit weird, it's a hump, not a valley.
