Preconstruction antitermite treatment to the building under construction by providing Stage 1: Treating the bottom and the sides (upto 30cm hight of the excavated trench @ 5 litter per sqm of the surface area. Stage 2: After masonry/RCC work, the backfill in the immdiate contact with the foundation structure treatment @ 7.5 litter per sqm. of the vertical surface of the substructure for each side. Stage 3: surface treatment by spreading emulsion over the plinth area before laying the base concrete under floors @ 5.0 litres/Sqm. Stage 4: Pumping the emulsion in plinth masonry on filling side at floor junction @ 7.5 litres/Sqm. Stage 5: Pumping the emulsion from outer side of the plinth below ground alround the masonry @ 5.0 litres/Sqm as per I.S. 8944 Emulsion. (1 Chlorpyrifos: 19 water) with five years service guarantee (Measurements to be taken for plinth area) Note - Treatment should start when foundation trenches and pits are ready to take bed concrete or leveling course in foundations. Laying of bed concrete should start when the chemical emulsion has been absorbed by the soil and the surface is reasonably dry. Treatment should not be carried out when it is raining or when soil is wet with rain or subsoil water. This also applies to filled up soil within the plinth area before laying the subgrade for flooring
