I live in Europe with a house constructed out of perforated bricks. I have sub grade basement windows. Our home inspector pointed out that the foundation edges exposed by the window channel need hydro isolation. We already have a major problem with mice falling in there, then tunneling through the foam insulation/sheathing all around the house.
What is the correct way to seal these edges? Each layer is very uneven, so I see potential problems with asphalt based paints or membranes, but would appreciate all advice.
Hard to see in the picture, but there is a drain at the base of each window cavity for water egress.
