Brick on edge masonry in cement mortar shall be laid on the plinth wall. Dry brick shall be placed on the inner side of plinth wall for getting anticipated offset space for coarse sand and on the other side for installing anti-termite masonry groove. In the case of intermediate walls, dry bricks are placed on either side of the brick on edge masonry for getting offset space for coarse sand layer.

The dry brick for the anti-termite groove shall be taken out and dense cement concrete 1 : 3 : 6 ( 1 cement : 3 sand : 6 coarse aggregate, by volume ) sub-floor carpet shall be laid casting the anti-termite groove in position. In case of internal partition walls, the cement concrete subfloor shall be laid on either side over the dry bricks to sufficient extent for getting staggered vertical joints over the joint of plinth wall and earth filling.
