Re: Building up off a retaining wall

Hi, we have just started getting damp on one side of our house, we had a patch of rock wool removed previously in the year where the wall started blistering. On checking we have found the rock wool is soaked and this is penetrating to the inside wall. Since then a new patch has appeared. Does anyone...
