My house is just over 2 years old. I have noticed on the cinder blocks in the
inside of the garage that there is a white power on a few of them. Also, on the
front of the house there are some rough-faced concrete blocks that make up the
front stoop that also have white powder on them. I have heard this is a
moisture related issue, but my house is not in a low area and there are no
drainage problems. What's going on?
