YF IL CONCLUSION: In our opinion, a Ajf waterproofing membrane needs to be install under all metal coping and precast capstones. Voids in the brick mortar need to be fill and the brick needs a penetrating sealer applied. New t flashing details need to be installed around all 11;.1} � windows and the base of the wall at the brick ledge.
