Brick flooring is suitable for cheap construction, and for places where heavy articles are to be stored as in case of ware houses, stores and godowns. Brick flooring is commonly used in alluvial places, where stone is scarce and well burnt bricks of good quality are readily available. The brick flooring may be laid with bricks laid flat, or on edge arranged in hearing-bone pattern, or set at right angles to the walls.

The bricks, whether laid flat or on edge, are set in ordinary mortar and pointed with cement, or set in hydraulic mortar. Brick-on edge is preferred to bricks laid flat, because the former being less liable to crack under pressure than the latter and also having the higher depth gives a greater thickness in the former case to resist the moisture penetration.

The method of brick flooring is as follows,

First of all, an excavation is made about 40 cm or so below the intended surface or level of the floor depending upon the nature of soil and the type of structure. The earth is then levelled, watered and well rammed, until it becomesdry and hard. On the bed so prepared, the sub-grade should be made with a 25 cm layer of rubble or brick bats, and covered with 10 to 15 cm thick layer of lime concrete or lean cement concrete (1 cement : 3 sand : 6 C.A.). Upon the prepared subgrade, the bricks are laid in desired shape (may be in parallel rows or herring-bone pattern) and set in cement or lime mortar. The joints should be preferably be 1.5 mm in thickness. The joints, sometimes may be required to be pointed to have better appearance. For Pointing purposes, the mortar is first raked out from the joints to a depth of about 2 cm and then pointed with cement mortar. For brick flooring outside the building, the bricks joints are grouted with dry sand and the process is termed as sand grouting.
Merits of brick flooring:

• It offers a durable and sufficiently hard floor surface.
• It provides a non-slippery and fire-resistant surface.
• It is cheaper in initial cost as compared to cement concrete, mosaic, terrazzo flooring, etc.,
• It is easy in maintenance.

Demerits:

• The only drawback of this flooring is that it is water absorbent.
