My house has a rec room built on the concrete slab, it is on the ground
level on one side, about 2 feel below ground on the other.
We had problem with water standing in the furnace room next to it, but now
since few days it is dry.
about a week a go a spot in the middle of the room got wet, then it become a
long patch (about 4 by on feet).
Since we have just replaced carpet in this room i am really hesitant to rip
it off to see what is happening under but do i have any other option?
the room that used to be wet is about 4 feet away from the wet spot and
there is nothing wet in between, the room is dry now
but the wet spot keep reappearing each time after I dry it by pointing a
fan.directly at it.
Can it be a surface leak from that furnace room and i should wait longer for
the situation to stabilize, or does it have to be a crack in the concrete
slab? any other explanations??
