The bottom and the sides (up to height of 300 mm) of the excavated area shall be treated with the chemical at the rate of 5 Lit/M2 of the surface area.,The backfill earth that is in immediate contact with the foundation structure shall be treated at the rate of 7.5 Lit /M2 of the vertical surface.

The top surface of the consolidated earth within plinth walls shall be treated with chemical emulsion at the rate of 5 lit/m2 of the surface before the sand bed or sub-grade is laid. If the filled earth has been well rammed and the surface does not allow the emulsion to seep through, holes up to 50 to 75 mm deep at 150 mm centres both ways maybe made with 12 mm diameter mild steel rod on the surface to facilitate saturation of the soil with the chemical emulsion.

After the building is complete, the earth along the external perimeter of the building should be rodded at intervals of 150 mm and to a depth of 300 mm. The rods should be moved backward and forward parallel to the wall to break up the earth and chemical emulsion poured along the wall at the rate of 7.5 l/m2of vertical surfaces. After the treatment, the earth should be tamped back into place. Should the earth outside thebuilding be graded on completion of building, this , treatment should be carried out on completion of such grading.

In the event of filling being more than 300 mm, the external perimeter treatment shall extend to the full depth of filling upto the ground level so as to ensure continuity of the chemical barrier.

DOSAGE:

Dilution 1 : 476 Ratio for making the chemical emulsion

The inner walls of the building at floor and wall junction will be drilled where accessibility is present The chemical used will be from M/s BAYER INDIA

Rodding will be done at 2 Feet span 6 inches away from the building perimeter to a depth of 10-12 inches and imidachloprid emulsion is poured into the holes to wet soil below the ground

DOSAGE:

Dilution 1 :476 Ratio for the control of termite in buildings during post construction anti-termite treatment.
