Okay heres the thing.
Just a few minutes ago the wall started to have these cracking
noises.
A side-angle view of the wall showed the tiles were pushing
out.
It's like swollen and there's this bump that is about 1.8m by
1.3m.
This bump has been accumulating. This is the second time in
3 years.
We gonna have it checked out soon.
The last thing I need right now is my own family to get hurt.
Have you guys experienced this?
