1954 house, block walls. What I think is called a floating basement floor. 1-1/2" gap around inside perimeter, there is a sump pump. The drain channel is either not pitched right or full of sediment. I want to put a drain in the floor right into the sump. We started to access the floor and found a footer.
Do I need to go inside the footer or can this only be done from the outside? This will be a living space and so has to be dry and mold free.
Do I need to create a vapor barrier between the block wall and the living space?
