WORK METHODOLOGY / PROCEDURE OF ANTI-TERMITE
TREATMENT
a.
MATERIAL
Chemical to be used:
1. Imidacloprid 30.5% SC- @ 2.1ml/liter of water.
2. Chlopyriphos 20% EC - @ 50 ml/liter of water.
OR
Equivalent Approved Chemical as per project specification
a.
Pre-Construction Termite Treatment Stages:
a. sides and bottom surface of the foundation trenches and pits
b. Backfill earth on each side of all built up walls which are in contact
with foundations/sub surface soil
c. masonry / concrete surfaces which are in contact with sub surface soil
d. before grade slab which is resting on soil/filling
e. Treatment for without basement Buildings
i. Treatment to top surface of plinth filling
ii. Treatment at junction of wall and floor
iii. Treatment of soil along external perimeter
iv. Treatment of soil surrounding pipes, wastes and conduits
f. Treatment for with basement building
i. Treatment to soil below raft
ii. Treatment to soil along the retaining wall
iii. Treatment to soil along the external perimeter of the building
iv. Treatment of soil surrounding pipes, wastes and conduits
b.
Post Construction Anti-Termite Treatment (For Existing Buildings)
a. Loose soil around the walls of buildings
b. concrete cover or masonry apron around the walls of buildings
Pre- Construction Anti Termite Treatment as
per Pepcopp Pest Control Specification
The principal of the
treatment is to create a chemical barrier below and around the building so as
to deny entry to the termites into the buildings.
Treatment for without basement Buildings
The treatment will commence after the foundation and the plinth wall
construction is completed.
a.
Treatment to top surface of plinth filling:
After the soil filling is completed in the plinth area and before the
dry rubble packing, the entire surface of the filled soil and the top surface
of plinth wall/beam shall be treated with the chemical emulsion at 5 liter per
sq. m. or as per manufacture’s guidelines.
b.
Treatment at junction of wall and floor:
Roding shall be carried out along the junction of wall and soil filling
at 1 mtr. Intervals down up to 30 cm. emulsion shall be sprayed along the wall
junction at 1 liter per linear meter so that it mixes thoroughly with the
broken-up soil. The disturbed earth is then tamped back in place within 48
hours. Supplier / manufacturer guidelines will be followed.
c.
Treatment of soil along external perimeter:
The soil around the external perimeter of the building up to a depth of
30 cm shall be treated at 2.25 liter per linear meter of the plinth wall or as
per manufacturer’s advice.
d.
Treatment of soil surrounding pipes, wastes
and conduits:
When pipes, wastes and conduits enter the soil inside the area of the
foundation, the soil surrounding the point of entry must be loosened around
each such pipe, waste or conduit for a distance of 15 cm and up to a depth of
7.5cm and loosened soil shall be treated with chemical emulsion. Anti-termite
treatment will be applied to subsurface soil at least 2 hours before PCC or
soling whichever is applicable, and after laying of piles/conduits in position
during back filling operation, back fill & adjoining subsoil surface will
be treated again with anti-termite treatment
Treatment for with basement building
The treatment starts when the excavation is complete and before lying
soiling and PCC.
a.
Treatment
to soil below raft:
Before laying the rubble soling and PCC the compacted and leveled soil
shall be treated at 5 liter per sq. m.
b.
Treatment to soil along the retaining wall:
The soil coming in contact with the retaining wall shall be treated at 5
liter per sqm. the treatment shall follow the backfilling is done in stages of
30 cms but not exceed a depth of 1 meter.
c.
Treatment to soil along the external
perimeter of the building:
The soil around the external perimeter of the building up to a depth of
30 cm shall be treated at 2.25 liter per linear meter.
d.
Treatment of soil surrounding pipes, wastes
and conduits:
When pipes, wastes and conduits enter the soil inside the area of the
foundation, the soil surrounding the point of entry must be loosened around
each such pipe, waste or conduit for a distance of 15 cm and up to a depth of
7.5 cm and loosened soil shall be treated with chemical emulsion.
Essential requirement:
·
A copy of ground or basement floor plan should be made available to us
before the start of the work.
·
Water required for the treatment shall be supplied to us Free of Cost.
·
A suitable space shall be provided with lock and key arrangement for the
storage of chemicals and the equipments.
·
Customer should inform us about the stage of construction ready for
treatment with a notice period of 2 days. It is in the mutual interest that all
stages of the treatment are completed at appropriate time. As non availability
of the area for no fault of ours, no pro-rata refund/adjustment in bills will
be permitted. Also the treatment is not done as per specification, possibility
of re-infestation cannot be ruled out.
·
Treatment should not be carried out when it is raining or when the soil
saturated with sub-soil water.
·
Once formed treated soil barriers must not be disturbed. In case treated
soil is disturbed, immediately step shall be taken to restore the continuity
and completeness of barrier system at an additional cost to the customer.
·
This treatment does not give protection against dry-wood termite and
powder post beetles.
·
The structure should be isolated from any existing structure.
·
References will be drawings, relevant codes and manufacturer details.
