Hi,

I have started removing plaster from a wall showing signs of damp (tide/water marks and peeling paint at base of wall), 1900 house. Solid brick internal wall. Concrete floor. Moved in six years ago and had done damp work carried out to a number of walls. This wall had chemical injection to other side and replastered on other side of wall.
What is that black stuff likely to be I’m seeing along one section of the wall?

Thanks Malc.

What do you mean by skud the membrane?

Any thoughts on best way to stop damp returning? I know there’s lots of different views out there on damp. Somebody has mentioned limelite so the wall can release any moisture.

Is this room below ground level?
As the synthaproofe membrane has now been broken, it may need a new tanking system.
