Damp over concrete floor
In our groundfloor back bedroon we have a concrete floor with bitumen top, laid on 1978. A damp patch has appeared in the middle of the carpet. There is no staining on the ceiling above so it seems to be coming from below. Is this possible? The bitumen seems sound, but has white blobs of mould on it.

"It is either coming from a leaky pipe, possibly radiator or the damp proof membrane is compromised.
Prob best to roll carpet back and investigate from there."

There must be water leaking somewhere, hope this has been of some help to you, kind regards walter"
