First, a reminder of one of the reasons why were are tearing up the
basement. We found a lot of boards that had some water damage and
rot. Call me crazy, but I just don't think it is a good idea to trap
the water behind some paneling in a wet basement.
Here's a peek into the bathroom after doing a little demo. There was
a paneled box hiding the drain pipe before we started.
More nastiness found behind the paneling.
When we pulled the paneling out of the back of the old shower the
surface of the concrete block basement walls ended up on the floor.
The stuff was just crumbling off. I'm not sure what caused this.
Maybe acidic condensation behind the walls?
