Anti Termite Construction Stage-1

Earth free from roots, dead leaves, or other organic matter shall be placed and compacted in successive horizontal layers of loose material not more than 200 mm thick. Dry brick shall be inserted at least 50 mm in brick masonry for providing apron floor alround the periphery.



Anti Termite Construction Stage-2

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.



Anti Termite Construction Stage-3

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.




Anti Termite Construction Stage-4

Superstructure masonry shall be raised over the dense cement concrete sub-floor carpet and over-head jobs completed.



Anti Termite Construction Stage-5

The dry brick for coarse sand layer shall be removed and graded sand ( of size 3 to 5 mm ) layer at least 100 mm thick shall be compacted over the earth filling and underneath the partially laid dense cement concrete sub-floor carpet.



Anti Termite Construction Stage-6

Dense cement concrete ( 1 : 3 76 mix ) sub-floor at least 75 mm thick shall be laid over the sand filling. Necessary finish may be provided to the cement concrete sub-floor carpet.



Anti Termite Construction Stage-7

Dry brick provided for apron floor ( see 4.1.1) shall be taken out and 600 mm wide formation of earth in 1 : 30 slope shall be made. Over the formation, 75 mm thick lime concrete 1 : 3 : 6 ( 1 lime: 3 sand : G-coarse aggregate, by volume ) shall be laid.



Anti Termite Construction Stage-8

Over the 75 mm thick lime concrete bed at least 25 mm thick cement concrete topping 1 : 2 : 4 ( 1 cement : 2 sand : 4 fine aggregate, by volume ) shall be laid and 12 mm thick cement plaster shall be applied on foundation and plinth.
