Hi
I have and old stone walled (600mm) mid-terraced house which has some rising damp.
I have hacked off 4ft (vertically) of the old lime plaster and found the screed was damp around the edges of the floor.
I hacked away about 50-75mm (horizontally) of the screed and found the footings of the old wall protrude in about 2" then there is a sheet DPM which has been cut with a knife to the concrete slab level so the screed was effectively bridging over the dpm leaving a path for the moisture to travel vertically to the plaster and horizontally into the floor screed.
I was thinking of applying a liquid dpm over the part of the old footings that protrude into the room but I'm not sure if the liquid dpm will 'bond' to the sheet dpm to create a continuous barrier
Has anyone else encountered this situation and tried this method or am I going about this the wrong way?
Thanks in advance
