I have an ICF construction coming out of a hill, it has a waterproofed retaining up one level the construction is designed with an outer brick skin which is knitted into another retaining wall to it's side so that they support each other. How do you put in a vertical dpc where the brick skin extends out the hill to continues along the wall so that moisture would not travel horizontally into the skin. The walls are already built but I should like to how that would have been done equitably and a remedial solution if it hasn't, possibly injection.
