    In a masonry cavity wall, there is usually a DPC in both the outer and inner wall. [8] In the outer wall it is normally 150 millimetres (5.9 in) to 200 mm (7.9 in) above ground level (the height of 2-3 brick courses). This allows rain to form puddles and splash up off the ground, without saturating the wall above DPC level.
