What could be dome to prevent capillary moisture? I have one internal wall 1.5 foot thick (dividing
two halves of the old town home duplex) that is made of porouse brick & cement. On the contrary, the perimiter walls and the floor slab are made of new solid concrete, there is no moisture there.
That internal wall seems to allow the moisture to creep up from the footing (of the wall) through the capillars. It shows some wet/mildew spots at random heights and distances from the house external sides. That makes me think the water comes up from the ground below the house finding its easy way up through this porous divider wall.
Is there any way to seal the capillars at the footing? I have heard of some silicon base sealant that could be injected through the predrilled holes near the footing of the wall. Does anyone know about this?
any help is greatly appreciated!
