«It’s obviously Bugs Bunny on speed.»
Can anyone Explain This?
«Yes, this is very disturbing. The structural slab is bowing down in the centre, causing the tiles on top to compress against each other until they are forced to pop up to relieve the pressure. This building should be evacuated of humans immediately.»
«Sink hole. I'd wager the whole building is shifting because the land underneath is shifting.»
«Radiant floor heat. The floor has pex tubing running underneath the tile. The lines expanded and popped the mortar and tiles is my best guess»
«There was a building collapse in Seoul years ago. Killed a lot of people but those on the top floor escaped because the supports under the floor started to protrude through the tiles. Someone pulled the fire alarm but most ignored it and died.»
«Let me guess, the house is not build on solid ground.
That's leaded to groud stress, which the tiles cannot handle, later appears cracks on the walls which are perfect indixators of the forces.»
