This is an interior foundation wall. Shots are of both sides, crawlspace side has visible waterproofing as you can see. The amount of efflourescence is pretty consistant all the way across the floor, rising up about a foot from the floor and fairly heavily encrusted in areas and not necessarily toward the exterior.
Soil in the crawl and basement was mostly dry and efflourescence was no worse where grade dips down on the crawl side.
Grade outside the home is OK.
Dampness at far end may be from snowdrift melt (low pressure area just outide due to deck), but there was no moisture in this area in the crawlspace side of the wall.
Looks to me as though it’s wicking up from beneath the wall.
This is at 8500 ft. elev. and you drive fifty feet up a steep drive to get to the home, so no high water table. No stream near.
