How should the floor be treated at the junction of walls?

Drill 12 mm holes at 300 mm intervals, rodding the holes to the soil below, and pouring 1 litre of chemical emulsion per hole. (Clause 5.1.1.2)

How do you treat termite infestation in woodwork like a door frame?

Drill holes at a downward angle of 45 degrees at the base of the frame and inject chemical emulsion. Also, spray all infested areas. (Clause 5.3.1)

What is the procedure for treating voids in masonry walls?

Drill holes in the wall at the plinth level, about 300 mm apart, and squirt chemical emulsion into the voids at a rate of 1 litre per linear metre. (Clause 5.2)

This standard provides guidelines for the chemical treatment of soil during the pre-construction phase to protect buildings from subterranean termites. It outlines the specific chemicals, their concentrations, and the detailed procedures for application at various stages like foundation excavation, backfilling, and flooring. The objective is to create a continuous chemical barrier around and under the building structure.

Practical Notes

The list of recommended chemicals in Annex A is outdated. Always refer to the latest list of approved termiticides published by the Central Insecticides Board & Registration Committee (CIB&RC).

Ensure adequate ventilation and use of appropriate Personal Protective Equipment (PPE) during and after chemical application due to the toxicity of termiticides.

Treatment is most effective when the soil and structure are relatively dry, allowing for better penetration and absorption of the chemical emulsion.
