Efflorescence on cinder block foundation wall.

East York detached home. Originally built 50+ years ago. Torn down and rebuilt about 10 years ago. Cinder block foundation walls. Mostly finished basement. Efflorescence appears in several places. Several versions of the same, white, crumbly stuff.

I'm not sure what your question is

Efflorescence is caused by moisture migrating thru masonry. Does the house have gutters that are piped away from the foundation?

Water infiltration is best addressed outside with gutters, grading and downspout extensions.
