Always add a dpc beneath the coping - this will protect the wall from water penetration around the joints in the coping. Flexible high bond impermeable materials are suitable for this lightly-loaded situation, but two courses of slate laid to break joint can also be used. Under brick cappings, slates or tiles can be used as a dpc (a separate flexible dpc should be included under tiles unless special dpc tiles are used). Slates and tile dpcs are also intended to shed rainwater clear of the wall and should project about 45 mm. In very sheltered areas (or when frost resistant materials are used throughout the wall) it is possible to use a rigid dpc with minimal overhang, or even just a flexible dpc.
