I have a section of wall at the back of the house which never sees the sun.
The wall has been repointed and a window blocked up this summer.
Prior to this there was a hole in the wall higher up where the soil pipe was and the bath outlet pipe. These were open for quite a few months as the house was renovated. On two occasions we had a heavy rain and i think water tracked into these holes and it came through on the inside wall in the lounge (behind the blocked up window).
The inside is now dry, but the outside seems to get wet in the lower area behind the soil stack.
Any idea what could be the problem?
I don't think it is anything to do with the bridging of the damp course by the gravel area.
I don't think the soil pipe is an issue. I renewed the stack and place a new drain connector into the clay bend at the bottom of the stack.
Could it be an issue with the cavity insulation ?
Ideas appreciated
