Its basically got a trench all around the inside that has water seeping in from the edges and the trenches go to a sump pump. Short term im planing on installing drainage pipe in the trench then concreting over it to reduce the water exposed to the air. Long term I'll eventually have to excavate around the house, install drainage, repair and reseal the foundation.

I guess i could try to just install vapor barrier over the trench and it would have a similar effect.

The crawlspace is closer to a short unfinished basement. I can stand between the joists in most places.
