A typical brick wall structure normally contains the following components:
(i) a coping on top of the brick wall to protect it from weather;
(ii) a firm foundation to support the loads on the brick wall; and
(iii) a damp course near the base of the brick wall to avoid the occurrence of rising damp from the ground.
(ii) render the brick wall weatherproof and waterproof; and
(iii) provide even beds to enhance uniform distribution of loads.
