I have acquired a house with a damp problem. Some time ago the floor was filled in with (I assume) concrete and 15mm bitumen/ash felt layed on top.
I think the concrete floor is bridging the existing slate dpc causing rising damp. Various injected dpc attempts have failed.
I am having an area where an old fire place was relayed with ash felt and the hall relayed too as it is very uneven.
What I'm thinking about is doing cutting out the edges of the concrete floor to lower than the slate dpc and filling it with ash felt too.
Does this sound like a good idea? or could there be some disadvantages I've not thought of?
