The water and related moisture may be one of the reason for all of the insulation falling down.
The delay from the rain to the arrival of the puddles could be due to a ground water source vs directly through the foundation. In any case, you have a problem. And your conclusion that it was not pipes, if correct means it has to be from the soil.
My proposal would be to clean up the space, level it and pour a couple of inches of concrete, referred to as a rat slab, over a good vapor barrier. The problem with just installing a vapor barrier is it will float when the water comes in.
In addition to the concrete you will want an interior drain system dumping that water into a sump pit where it can be discharged away from the house.
Even though this may not be directly related to rain fall next to the house, landscaping, and extended leaders to move as much water as possible as far away as you can is important.
The perimeter drain to a sump pit would probably be a good starting point.
