Ordinary masonry walls are reinforced with iron bars or expanded metal mesh and such walls are called reinforced brick walls. Here, the reinforcement, iron bars or expanded metal mesh are provided at every third or fourth course (Fig. 17.11).

Alternately flat bars of sections about 25 mm × 15 mm may be used as loop iron reinforcement for walls (Fig. 17.12). They are hooked at corners and junctions. In order to increase the resistance against rusting, the bars are dipped in tar and sanded immediately.

Reinforcement in vertical direction is provided by using special bricks or blocks as shown in Fig. 17.13. Mild steel bars of 6 mm diameter may also be used as longitudinal reinforcement in walls.
