What is that white chalky substance on the walls?
Efflorescence. Concrete is made of three materials, stone, lime cement, and stone. What you are seeing is a chemical breakdown of the bonding agent that holds your wall together. The water that is inside of your foundation wall will, over time, leech the lime cement out of the wall, leaving nothing to hold it together.
