weakness folded into ridges until it becomes strong enough to roof the world
means Shaped into parallel ridges and grooves, giving a thin or flexible material far more rigidity and strength.
from From Latin 'corrugare,' to wrinkle or fold up — built from 'com-' (together, intensifying) and 'ruga,' a wrinkle or crease. The same 'ruga' that puckers a brow puckers the iron and cardboard, the wrinkle simply scaled up until it could hold weight.
