Construction Details of Ground Floorings

A brief construction detail of a few of the significant types of ground flooring is given below, and for others learner might refer any of the standard text on this subject.

Brick Flooring

This type of flooring is appropriate for cheap construction, especially while good bricks are available. This flooring is especially appropriate to ware-houses, stores, godowns etc. Brick flooring is generally used in alluvial places. Well-burnt bricks of good color and uniform shapes are used. Bricks are laid either flat or on edge, arranged within herring hone fashion or set at right angles to the walls, or set any other good looking pattern (Figure 2).

The technique of preparing the base course for brick flooring varies from place to place. In one technique, the sub-grade is compacted properly to a desired stage and a 7.5 cm thick layer of sand is spread. Over this, a course of bricks laid flat in mortar is built. This forms the base course, over that the brick flooring is laid in 12 mm thick bed of cement or lime mortar, within the desired pattern. In the second techniques, 10 to 15 cm thick layer of lean cement concrete (1: 8: 16) or lime concrete is laid over the prepared subgrade. This creates the base course, over that bricks are laid on edge (or flat) on 12 mm thick mortar bed within such a way in which all the joints are full along with mortar. In both the cases, the joints are rendered flush and completed. The work is then properly cured.
