I'm at a loss. I'm building a room in our basement and tonight I found a pile of sand around one stud spilling onto the floor ??? Now this was not there 2 weeks ago when I was pulling some electric. My neighbor who was helping me frame a door tonight said he finds this around his walls at certain spots sometimes but never that much so quick. We have been here 7yrs now and I never saw this before. The basement was finished when bought the house but I gutted it due to termites. The funny part is it seems to be coming up through the floor, its dry and very fine.
I searched but I'm coming up with nothing. Does anybody know what is going on here?
