Lesson 06 : Termite Proofing

Treatment Of Soil along external periphery of building

Despite the treatments given above, termites are liable to gain access in the building from ground surface around the external periphery of the building. In order to check this, 300 mm deep holes at 150 mm centre are dug all along the external perimeter of the building (parallel to the external wall) and filled with chemical emulsion at the rate of 2.25 liters per linear meter. After the treatment the earth should be tamped back in the holes. In case the building is to have apron on the external walls, the area of consolidated earth filling over which the apron is to be constructed should be treated with chemical emulsion at the rate of 5 liters per sq. meter prior to the construction of the apron.
