Hi there,
I live in the basement flat of a Victorian house conversion. The whole flat, with the exception of the bathroom, is covered with Carndean flooring strips over what I assume is a concrete floor.
Lately, I've noticed that a small amount of water is seeping up the gap between the strips in the spare bedroom. This part of the floor is a corner, adjacent to an outside wall and the wall of the bathroom. That corner in the bathroom is where the head of the bath and shower is.
My first guess was that the water is caused by a leaky seal around the bath, so I have redone this. The other options are (I guess) water from the outside wall or from ground water, but since the house is on the top of a hill, I assume this is less likely.
Does anybody have any advice on how to tackle this problem? Should I call in some kind of expert to look at my exterior wall or to check for damp elsewhere? Should I hire a dehumidifier (or some other tool) to tackle the existing water? Now that I've resealed the bath, how long will I need to wait to see whether this solution has been effective?
Thanks,
Peter
