TERMITE CONTROL APPLICATION PROCEDURE – ANTITERMITE
Ensure the material/supplier approval obtained from the Engineer. The material approval shall be as per the standard project anti termite control specifications.
Before chemical application, all extraneous sources of cellulose and other edible materials such as wood debris, tree stumps, root stakes, construction soil and waste wood shall be removed from the treated areas.
All foreign matters and impermeable soil material which decrease the termite treatment effectiveness shall be removed from the treated area.
Formation shall be compacted and tested prior to the application of anti termite.
Manufacturer’s instructions/procedures including dilution and application shall be strictly followed during termite control application.
The treated areas shall be covered with polythene sheet as soon as the treatment is completed.
Treated areas shall be kept undisturbed as per manufacturer recommendation in order to allow chemical to bind strongly with the soil.
In case if the soil removed from the treated areas and rains after the treatment, the areas shall be treated again in order to restore the continuity of the chemical barrier.
Anti Termite Treatment Stages
The anti termite treatment works shall be carried out in four stages during the construction of building, which are as under:
Termite treatment to Soil under substructure slabs.
Treatment to Soil along the External Perimeter of the Building
Mixing of Chemical
For every liter of chemical 49 liters of water shall be mixed. In plain horizontal surfaces a 5ltr/m2 dose shall be applied. For trenches and edges a 6ltr/m dose shall be used.
Chemical Application
The one 5 liter dose Chemical shall be added to the 500 liter tank. The pump machine shall be set to 20bar pressure that shall produce a flow of 5 liters per 15seconds. So, in 15 seconds an area of 1 sq. m will be covered. For the linear meter applications the pump shall be set to 15 bar pressure to produce a 6 liter per 20second flow and this shall cover a distance of one linear meter.
Treatment to Soil under Slabs at Plinth Level
The treatment to soil under slabs at plinth level shall be carried out into following sequence
Foundation Termite Control Treatment
A trench 200 x 200mm x total perimeter, along proposed foundation shall be excavated.
Application of termite control along trench shall be done with 6 liters per linear meter of Contra Insect 480 TEC mixed with water using 1:49 ratio.
Backfill of trench up to existing foundation level shall be done in preparation for second application of termite treatment.
Upon completion, 5 liters per square meter of Contra Insect 480 TEC mixed with water (1:49 ratio) shall be applied.
On completion, the treated area shall remain undisturbed for two hours. After two hours polyethylene sheets can be placed over the treated area.
Preparation for structural works shall be done only within 24 hours for the anti-termite application to remain effective.
Under Pile Cap
On the cleared and levelled ground the anti-termite treatment shall be done using 5 liters per square meter of Contra Insect 480 TEC mixed with water using 1:49 ratio.

Preparation for structural works shall be done only within 24 hours for the anti-termite application to remain effective
Ground Beam/PCC
Application of termite control chemical shall be done at the rate of 5 liters per square meter of Contra Insect 480 TEC mixed with water at a ratio of 1:49 and covered by polythene sheets after 2 hours.
Preparation for structural works shall be done only within 24 hours for the anti-termite application to remain effective
When the ground beam/pick shall be cast, excavate a trench 200 x 200mm along the perimeter of ground beam/ PCC. The Anti-Termite treatment shall be done with 6 liters per linear meter of Contra Insect 480 TEC mixed with water using 1:49 ratio.
After completion of anti-termite application the trench shall be backfilled.
Termite Control for Slab on Ground
Excavate a trench 200 x 200mm along perimeter of the slab.
Application of Anti-Termite shall be done with 6 liters per linear meter of Contra Insect 480 TEC mixed with water using 1:49 ratio. After completion, the trench shall be backfilled and levelled.
Application of Anti-Termite shall be done with 5 liters per square meter of Contra Insect 480 TEC mixed with water using 1:49 ratio along the substructure slab area.
On completion, the treated area shall be covered with polyethylene sheets after two hours from application
