Half Brick Wall (Four & Half inch thick wall)
A four-and-a-half inch or half brick wall is ad quate for small, single storey houses and is apt for partition walls. These walls are adequately strong up to a span of 2 meters. However, an isolated, long, half brick wall may fall, get knocked over, or get crushed by roof load. The stability of the wall can be ensured by providing buttresses or recesses. Also the junctions of these walls increase the stability. Thus the stability of these walls greatly depends upon designing and planning.
Half brick walls, apart from being efficient, are also economic as they use almost half the number of bricks and even less mortar than used for full brick walls. They also save the labour charges, as they are less time consuming and easier to build.
