wall and how to fix it.

We think that behind the cement/concrete wall is just earth.

Do we just dig out the damp section, patch and seal?

Just start tanking things apart until you find all the known and
suspected problems. You won't know until you look.

10' X 10' back of the house extension built in the 1950's on a 1925
house. What we call a "mud room" for coming in the back door and
then either going up to the kitchen or down to the basement.

We think the extension was built flat on the ground, except for the
stairs leading down to the original 1925 basement.

The exterior of the extension is old, cracked and falling off in
chunks insul-brick.

We've noticed a small (6" by 8") damp patch on the wall of the lower
stairs which lead from the mud room to the original basement.

We were thinking that the insul-brick needs to be replaced, but at
the same time we should have waterproofing done below ground level
of the extension. We suspect, given the age of the extension, this
was never done.

We think the damp spot on the wall is just the wet solid earth
behind the wall of the extension where it is below ground. We have
no dampness at all in the original basement area.
