Hi, hoping this is a good place to start...
I have a 1950's ex LA semi with cavity wall and a stepped footing. I have been looking into cavity wall insulation and have been advised that this isn't possible (using standard insulation materials) due to the damp course being below the stepped footing and the risk of water coming through above the step and entering the house via the damp course.
I can see the logic, but has anyone any frame of reference for this?
Apparently there are gel options that are very costly. I wondered if there were any better options?
