This type of flooring is used in case of warehouses, stores and godowns. This is a cheap construction and used in areas when stones are not available but good quality bricks are available.
This flooring may be laid flat or on edge. They may be arranged in herring bone pattern or at right angles to the walls. Brick on edge is preferred compared to bricks laid flat as the brick on edge is less liable for crack under pressure because of the higher depths. The bricks, in both the cases, are laid on ordinary mortar and pointed with cement or set in hydraulic mortar.
The construction of brick flooring is done as explained below, Fig. 23.2:
- An excavation of about 40 cm depth below the intended level of the floor is made.
- The earth surface is levelled, watered and well rimmed until it is dry and hard.
- Over the earth, above a sub-grade of 25 cm depth consisting of rubble or brickbats is laid.
- Over this, a 10–15 cm thick layer of lime concrete or lean cement concrete (1:3:6) is laid.
- Upon this prepared sub-grade, bricks are laid in the desired shape.
