Pre Construction Anti Termite Treatment: Process and Benefits
This treatment takes place before the construction completes. In this anti-termite treatment, the soil, building pillars and other joints are treated with chemicals to prevent termites. Pre-construction anti-termite treatment is considered as most effective way to prevent termite invasion in buildings or homes. In this soil under the foundation is treated with chemicals. A chemical barrier is formed between ground and brickwork of the foundation to avoid termites access to the building.
Termites popularly known as white ants cause considerable damage to wood works, furnishing etc. of buildings Termite control in building is very important as the damage likely to be caused by the termite is huge.
Procedure :-
Under PCC of FoundationAfter the advice of the Engineer to proceed, the application shall immediately begin by first preparing and mixing the solutions of Approved Anti-termite material diluted with water at a rate of 1:49 Liter water as per manufacturer’s recommendation.A solution of approved Anti-termite material diluted with water at a rate of 1:49 Liter shall be sprayed prior to casting of blinding of footing or any foundation type with the application rate of 4 to 5 liter per square meter.The treated area shall then be covered with polythene sheet, it can be opened free until 2 hours, and then casting can be started. Casting must be completed by 2 to 24 hours after the Anti-termite application.
Trench Around the Foundation Wall
Backfill the sides up to the top level of the proposed foundation ( considering that the height of the foundation will exceed more than 1 meter).Make a trench with 150mm width by a 150mm depth along the perimeter of the foundation.A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter shall be sprayed with an application rate of 5 -6 Liter per linear meter int the trench along the perimeter of the foundation.The trench shall be back filled within 24 hours of treatment.
Under PCC of Tie Beam
A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter shall be sprayed prior to the casting of PCC of tie beams with the application rate of 4 to 5 Liter square meter.The treated area must be immediately covered by polythene sheet, it can be uncovered for 2 hours before casting. And castingmust be completed by 2 to 24 hours after Anti-termite application
Underground Slab and Along the Side of the Beams
The trench shall be constructed with a measure of 150mm by a 150mm depth along the perimeter of the tie beams.A solution of the Approved Anti-termite material diluted with water at a rate of 1:49 Liter will be sprayed prior to ground slab casting with the application rate of 4 to 5 per square meter.With the same solution of Approved Anti-termite material, apply 5 to 6 Liter per linear meter into the trench along the perimeter of the tie beams. Back fill the trench after letting the termiticide subside within 2 hours. The back filling must be done within 2 to 24 hours after anti-termite application
Along the Outside Perimeter of the Building
Make a trench, 150mm in width and 150mm in depth, along with the external perimeter of the building at the same level of the landscape.
A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter will be sprayed into the trench along the external perimeter of the building with an application rate of 5 to 6 Liter per linear meter.
Back fill the trench within 2 to 24 hours after the treatment .
