Hi all! This is my first post here. My husband and I are about to install a
new tile floor in our kitchen that we are remodeling. When we were doing the
drywall and had the cement slab covered with plastic, we noticed that a couple
of areas were damp when we took the plastic up. Not a lot of water or
anything, just a slightly discolored area where the cement was damp.
Is this normal to have a small amount of moisture? Our concern is that when we
installed tile in our bathroom, the grout discolored in one area and we think
it may be from moisture there. We don't want to have this happen in the
And we are also worried that it might be an indication of problems to come.
So is there any way to check for leaks under a slab?
Our house is about 40 years old. We haven't any idea what if anything needs to
be done about this. But would rather do it now than when the remodel is
Also, is there anyway to put some kind of moisture barrier down on top of the
cement that we can tile on top of? And would that be neccesary?
Any help from all you pros would be appreciated.
