Sad, but true...
A full slump in a basement floor is one thing, all that slab is going to do is lay there. but those precast panels will have to be moved and stood vertically. The only way i can see them haveing any nstrength would be if they are made of some kind of epoxy or resin mix possibly would even have fiber in it.
