White powdery stuff on outside foundation wall
Posted by Mike on May 12, 2003 at 19:03:09:
I have a white powdery lines on my foundation on the North side of my house. The crawl space underneath the house is dry and there is no cracks on the walls. There is no water underneath and I have a vapor barrier on the floor. What could be the cause and how do I get rid of it?
