House is an end terraced stone built victorian era house. The picture shows the outer wall (along the back) and an inner wall. I have read lots about rising damp and if it exists or not.
The picture shows the problem I have. The outside ground level is lower, so its not penetrating above a bridged dpc. I have had to take the wall back to the stone to let it dry our. Before I did it appears that the previous owner has rendered the inside walls and then plastered over that with normal gypsum multi. Dont know how long its been like that, but the plaster work was like a damp sponge.
I have compared the mortar above the damp with that from the damp area, and the two are clearly different. The mortar from above contains hair, the one from the damp is crumbly and does not contain these fibres.
I dont know if its rising damp or not - but I do know that in the area showing the damp it is not the original render/plaster.
What do you guys think? Whats the best solution? I was gonna use dry zone and re-render it all, but i'm not 100% this is rising damp, although you'd have to agree it does look like it.
