List of Contents
1. All chemical used for anti-termite treatment are poisonous and hazardous to health.
2. Keep the containers closed and secured.3. Wear protective clothing while handling the chemicals.4. Avoid flames in the vicinity during mixing.5. Never allow treatment chemicals to contaminate sources of drinking water.6. Follow instructions provided by the manufacturer in the MSDS ( Material
Safety Data Sheet ). 7. In case of poisoning take remedial measures according to the MSDS
provided by the manufacturer and as per IS 4015.

Chemical Treatment for the Building.

3. Codes & Standards
Anti-Termite Treatment
This Presentation is Specific to IS 6313 Part 2
4. Submit Material Specification and MSDS to EIC before start of work
3. Follow Indian Standard Safety Code and Site Specific Safety rules
2. Anti-termite treatment should be carried out in the early stages of construction of buildings:- Start from substructure and up to plinth level.
1. Anti-termite treatment is a specialist job: Use only specialized agencies for carrying out anti-termite treatment preferably a member of Indian Pest Control Association.
4. General Requirements
Anti-Termite Treatment
1. Remove all organic matter, construction debris, rubbish etc.2. Water logged foundations shall be treated after drying when the soil is
absorbent.3. For low penetration and slopping sites, surface to be scarified 75mm depth.4. Complete all cutting, excavation, leveling & grading before starting
treatment .
5. Site Preparation
Anti-Termite Treatment
1. Chloropyriphos 20% EC bearing ISI certification .2. Dilute 1 part of Chloropyriphos 20% EC with 19 part of water to get 1%
emulsion.3. Indian pest control association approved chemical shall be used.4. Contractor shall submit purchase vouchers to EIC for verification.
6. Materials
Anti-Termite Treatment
1. Chemical emulsion should be applied uniformly by sprayers.2. Specified rates should be applied at each stages of treatment.3. Pressure pumps and sprayers of adequate capacity shall be used for proper
penetration of chemical.
7. Mode of Application and Rate of Application
Anti-Termite Treatment
1. Foundations shall be completely
enveloped with chemical barrier.2. Treatment shall be from sub
structure to plinth surface3. Apply emulsion @ 5 Ltrs/ Sqm
for normal load bearing structures
4. Vertical surfaces @ 7.50 Ltrs/Sqm.

Treatment in Foundation Trenches:In case of normal wall load bearing structures,
columns pits, wall trenches and basement, the treatment shall be at 5 litres/sqm. or surface area of the bottom and sides to a height of at least 300mm.
After the foundation work, the sides shall be treated at 7.5 litres/sqm. of vertical surface of substructure on each side.
After the earth filling is done, treatment shall be done by rodding the earth at 150mm centres close to wall surface and spraying the chemical with the above dose i.e. 7.5 litres/sqm.
In case of framed structure, the treatment shall start at a depth of 500mm below ground level. From this depth the backfill around the columns, beams and R.C.C. basement walls shall be treated at 7.5 litres / sqm. of the vertical and at 5 litres / sqm. for the horizontal surface at the bottom in the trenches / pits.
9. Treatment for RCC Foundations & Basement
1. Treatment shall start at a depth of 500 mm below the ground level/FML.
2. Apply emulsion for vertical surfaces @ 7.50 Ltrs/Sqm.

11. Junction of the Wall and Floors
Anti-Termite Treatment
1. Continuity of vertical chemical barrier on inner wall surface from ground level to finished floor level is required.
2. Treatment shall be carried out byi. Placing a channel of 30x30 mm at all junctions of wall and columns with
floor before sub grade is laid.ii. Make holes using 12 mm dia rod@ 150mm c/c and breakup the earth up
to ground level.iii. Pour chemical emulsion into the holes @ 7.5 Lit/Sqm. iv. Tamp back the soil into the channel and consolidate the earth.
1. Care to ensure that the chemical barrier is
complete and continuous.2. The treatment shall not be carried out when
it is raining or when the soil is wet.3. Treated soil surface shall not be disturbed.4. Take immediate steps to restore the
continuity and completeness of the barrier system if treated soil gets disturbed.
18. Precautions During and After Treatment
Anti-Termite Treatment
SPRAYING EQUIPMENT•A pressure pump shall be used to carry out spraying operations to facilitate proper penetration of chemical into the earth.The chemicals, concentration and dosage for horizontal and vertical surfaces are based on the IS code of practice for Anti-termite measures in Buildings. IS 6313 (Part-II).
PRECAUTIONS DURING MONSOON•No spraying shall be carried out when it rains. Treatment should be repeated in plinth areas if it rains immediately after a spraying operation and before the emulsion has soaked into the soil.
