Details on Anti-termite Treatment in construction site
Use of Anti-termite treatment in construction site is very crucial. It should be performed prior to binding works. The following points should be taken into consideration for anti-termite treatment :-
1. Preconstruction Activities:
a. Detach all wooden pieces, concrete debris, plastic strips, tree stump roots, deleterious materials etc.
b. The soil should be leveled and compacted for bottom of the blinding prior to apply the treatment.
c. Before starting the treatment, all relevant tests should be conducted as per the approval of the site engineer.
2. Construction Activities:
a. Under PCC of Foundation
b. After getting the approval of engineering for further proceeding, the application should start instantly initially arranging and mixing the solutions of approved anti-termite material diluted with water at a rate of 1:49 Liter water according to the suggestions of manufacturer.
c. A solution of approved Anti-termite material diluted with water at a rate of 1:49 Liter should be sprinkled before casting of blinding of footing or any foundation type with the application rate of 4 to 5 liter per square meter.
d. After that, the treated area should be covered with polythene sheet, it should be opened free till 2 hours, and then casting should be conducted. Casting should be finished within 2 to 24 hours after the use of Anti-termite.
3. Trench Around the Foundation Wall
4. Backfill the sides up to the top level of the projected foundation (assuming that the height of the foundation will surpass over 1 meter ).
5. Create a 150mm wide and 150mm deep trench across the perimeter of the foundation.
6. A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter should be sprinkled with an application rate of 5 -6 Liter per linear meter into the trench across the edge of the foundation.
7. The trench should be backfilled within 24 hours of treatment.
8. Under PCC of Tie Beam
9. A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter should be sprinkled before starting casting of PCC of tie beams with the application rate of 4 to 5 Liter square meter.
10. The treated area should be instantly wrapped with polythene sheet, it will be opened for 2 hours prior to casting. And casting should be finished within 2 to 24 hours after using the Anti-termite.
11. Underground Slab and Along the Side of the Beams
12. The trench should be built up with a measure of 150mm by a 150mm depth across the border of the tie beams.
13. A solution of the Approved Anti-termite material diluted with water at a rate of 1:49 Liter should be sprinkled before casting ground slab with the application rate of 4 to 5 per square meter.
14. With the similar solution of Approved Anti-termite material, use 5 to 6 Liter per linear meter into the trench across the border of the tie beams. Backfill the trench after allowing the termiticide to be settled within 2 hours. The backfilling should be accomplished within 2 to 24 hours after using the anti-termite.
15. Along the Outside Perimeter of the Building.
16. Create a 150mm in wide and 150mm deep trench, across the outside periphery of the building at the similar level of the landscape.
17. A solution of Approved Anti-termite material diluted with water at a rate of 1:49 Liter should be sprinkled into the trench across the external perimeter of the building with an application rate of 5 to 6 Liter per linear meter.
18. Back fill the trench within 2 to 24 hours after the treatment.
