1. Scope

How to Carry out of Pre-Constructional Anti-Termite Chemical Treatment for the Building.


2. Health Hazards and Safety Measures

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.


3. IS 6313 Part 3 – Treatment for Existing Buildings

2. IS 6313 Part 2 – Pre-Constructional Anti-Termite Measures in Buildings

1. IS 6313 Part 1 – Constructional Measures

IS 6313 - Code of practice for anti-termite measures in buildings.

3. Codes & Standards


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


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


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


7. Mode of Application and Rate of Application

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.


8. Treatment for Masonry Foundations & Basement

1. Foundations shall be completely enveloped with chemical barrier.

2. Treatment shall be from sub structure to plinth surface

3. Apply emulsion @ 5 Ltrs/ Sqm for normal load bearing structures

4. Vertical surfaces @ 7.50 Ltrs/Sqm.

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.

10. Top Surface of Plinth Filling

1. Consolidated plinth surface shall be treated.2. Treatment shall be @ 5 Ltrs/Sqm before sub-base is laid.3. If consolidated soil doesn't allow the emulsion to seep through,

i. Make holes using 12mm dia rod @ 150 mm c/c in both directions.ii. Depth of hole shall be 50mm to 75 mm.iii. Pour chemical emulsion into holes and allow to saturate.

11. Junction of the Wall and Floors


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.

12. External Perimeter of Building

1. The external perimeter of the building shall be treated.

2. The external perimeter of the building shall be roded at 150 mm c/c on both ways to make holes.

3. Minimum depth of hole shall be 300 mm.4. Pour the chemical emulsion in to the hole @

7.5 Ltr / Sqm of vertical surface.5. Tamp back the soil after treatment &

consolidate.6. If earth outside the building requires

grading, treatment shall be done after completion of grading.

Min 300 mm @ 7.5 Ltrs / Sqm

13. Soil Surrounding Pipes and Conduits

1. Service pipes entering the foundation/building shall be treated.2. Treatment shall be carried out at a distance of 300 mm away from pipe in

both Side.3. Depth of treatment shall be 75 mm below the pipe.4. At each entry points treatment shall be carried for a distance of min 1 mtr

away from building/ foundation entry point.

14. Expansion Joints

1. Soil beneath the expansion joints at ground level shall be treated.2. Expansion joint shall be treated after sub grade has been laid.3. Treatment shall be @ 2 Ltrs per running meter of expansion joint.

15. Treatment of Soil Under Apron


1. Consolidated soil below the below apron shall be treated.2. Treatment shall be @ 5 Ltrs/Sqm before sub-base is laid.3. If consolidated soil doesn't allow the emulsion to seep

through, i. Make holes using 12mm dia rod @ 150 mm c/c in both

directions.ii. Depth of hole shall be 50mm to 75 mm.iii. Pour chemical emulsion into holes and allow to saturate.5 Ltrs /

16. Treatment over DPC1. Top of concrete damp proof course in external and internal walls shall be treated.2. A liberal coat of chemical solution shall be applied when the concrete is still

green.


17. Treatment of Walls Retaining Soil above Floor Level

1. Retaining walls like the basements walls, outer walls above the floor level shall be treated.

2. Treatment shall be in the retaining soil in immediate vicinity of the wall.3. Treatment shall be carried @ 7.5 Ltr per Sq.mtr of vertical surface.


18. Precautions During and After Treatment

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.
