Hello, I recently saw a house design that was a bit unique to me. The house is a large four-level split with a half basement and the other half is a crawlspace. In the crawlspace, half of this area was a concrete slab, the other half was pea gravel. The concrete slab was dry and there was not much efflorescence to be found and no discernible smell unlike some I have seen. The pea gravel, however, was damp to the touch the entire way through and across the whole area it covered. Two teleposts were plunged into it and had rust residue near the base indicating this was likely an ongoing dampness. There was some poly loosely draped over it but definitely not sealed off. We were looking at purchasing this home but we're quite concerned about this. What are you thoughts on this situation and things we should look for more closely? We plan to take another look at the home this week and wouls get a home inspector in prior to purchasing but would like to save that only if this isn't something that would completely rule out consideration of this house. This is not an area we are particularly knowledgable in. Thank you
