Outdoor Wall Copings and Cappings
The function of copings and cappings are aesthetic as well as protective. The appearance of a wall may be dramatically changed by altering the coping or capping
The protective function is against vertical water penetration and in shedding rainwater clear of the face as effectively as possible. The ideal coping should be durable and waterproof weather and the brickwork and constructed preferably with interlocking units. The overhang should include a throating recess or a drip not less than 13 mm wide.
In many instances for aesthetic or functional reasons, it is necessary to use a brick-on-edge capping. Such a capping will perform reasonably well, provided that it is constructed in accordance with the recommendations of regulations. Suitable galvanised steel, stainless steel or non-ferrous metal anchors.
A minimum weight of 1.5 kN/m2 is preferred for copings with concrete or stone units. Some brick manufacturers can supply their own capping system which incorporates a dpc.
