METHOD PRE CONSTRUCTION TERMITE CONTROL TREATMENT

PRE CONSTRUCTION SOIL TREATMENT

Pre Construction Soil Treatment implies laying down a chemical barrier to prevent termites from getting back and forth between wood and soil. Termites need wood for food and soil for moisture, so they constantly travel back and forth between wood and soil. Where this situation does not exist, termites build the “shelter tubes” (Mud tubes) to span foundation walls and other parts of the building that separate wood from the soil. Besides building the tubes in and over foundation walls, termites may also build them inside the walls if constructed of concrete blocks or other porous material. In the case of slab buildings, termites enter through expansion joints, cracks, opening for utility and service connections.

EXECUTION & SEQUENCE OF WORK

Stage I – Plinth Treatment

Once the backfilling is completed and prior to lay the leveling screed of ground floor slab, Roding will be done along the edge of beams and on entire slab area at one meter center. Then the termiticide will be injected by means of pressure injection treatment.

In addition to the above treatment blanket spraying will be carried out on soil surface covered by the leveling screed of ground slab. Anti termite treatment will not be done under the base slab of sump, lifts and etc. which are in below the water table.

Stage II – Barrier Treatment

Once the leveling is completed in the building area along the exterior walls for paving Roding will be done along the foundation and termeticide will be injected to soil by creating an one meter wide effective chemical barrier along the exterior foundation.

CHEMICAL USED

1. The chemical used will be IMIDACLOPRID based termiticide the strength solution will be 2.5mlt. 1lt water emulsion.
2. The rate of used will be approx. 5Lit of mixture per 1Sq. Meter.

EPA approved chemical will be used for termite control purposes and the treatment process will not make any contamination on the ground water table and surface water sources in and around the site. The termiticide used is agricultural friendly chemical and it will not make any adverse effect on existing and proposed flora and fauna, in the park, such as trees plants and fish in the ponds.
