Post construction measures : Anti-termite treatment to the outside of foundations with chemical emulsion by admixing Imidacloprid emulsiflable concentrate (62 ml in 28.5 litres) with water by weight, drilling 12 mm. dia holes in concrete or masonary appron at an interval of 300 mm, to a depth of 300mm or more as close to the plinth wall as possible and the chemical emulsion pumped into those holes to soak the soil below at a rate 2.25 litres per linear meter complete as per specification laid down in para 5.3.1.2 of code I.S.-6313 (Part-III)-2013

Post construction measures : d) Anti-termite treatment to the junction of wood work and masonry walls with chemical emulsion by admixing Imidacloprid emulsiflable concentrate (42 ml in 20 litres) with water by weight including spraying at the points of contact with the adjoining masonry by drilling 6 mm. dia holes at a downward angle of about 45 degree at the junction of woodwork and masonry and squirting chemical emulsion into these holes at the rate of half litre per hole. The entire work is to be carried out as per specification laid down at table 1 & in para 5.3.1.3 of code I.S.-6313 (Part-III)- 2013. The shutters are to be sprayed with emulsion. on both sides.
