I live in a 1902 terraced with 9" solid wall that was previously damp. After consulting this forum, i was advised to tanking slurry followed by dot and dab insulated board.
I've put 4 layers of tanking slurry on and thoroughly dried for 2-3 weeks.
The plasterer has installed insulated plasterboard via dot and dab, and left a 2 inch gap at the bottom so it can dry/ventilate
If i put my hand up the back of the insulated plasterboard, there is water on the back/bottom of the insulated board
It has not come through the insulation and plasterboard. Before the PB was installed, the wall never felt wet to touch, just cold feel after it had rained.
Any idea?
