I've been having trouble for years with my crawl space getting saturated (no standing water) just in the winter months. It usually dries out by Aug, Sept. Now I notice path of saturation from one end of the house to the other. I can't figure out where it's coming from.
My concern here, unless someone has an idea of the above, is in one corner of the crawl space there's a depression in the ground near the foundation. It's got some white fuzzy stuff growing in there. I took plenty pictures, some of which I'll try to include here...well, that's not working. What is this and what can I do about it. I ended up pouring some borate around the area - don't know if that's what's really needed.
