Ok I have a partially finished basement its a big rec room 2 walls are painted block and 2 walls are drywalled. I have new carpet down. I want to put in another wall that goes from one of the finished walls to one of the block walls. I don't want to tear up the new carpet. so how do i anchor the new wall to the floor without concerns of moister getting up threw my anchor bolts i put threw the carpet and into the concrete floor. I need some advice as i would like to do this next weekend. The ceiling is finished drywall.
