METHOD OF TREATMENT FOR TERMITE CONTROL AVITUS INDIA PEST MANAGEMENT PVT. LTD. is using a New Generation Insecticide for Termite Control that contains IMIDACLOPRID as active ingredient. It is an appropriate insecticide for the control of Termites in building and premises, which can be used both for PRE & POST construction treatments. Mode of Action We create a non – detectable treated zone that function not as a repellent barrier, but as a “killing

7

field” whose effects may be transmissible to other Termites and leads to eradication of the colony. It acts by interfering with the transmission in the nervous system and resulting in their death. We are injecting concentrated Chemical Emulsion for Anti – Termite treatment for creating chemical barrier under & around column pits, wall trenches, basement, excavation, top surface of plinth filling junction of wall and floor along external perimeter of the building, expansion joints, surrounding of pipes conduits etc. PRE CONSTRUCTION TREATMENT

1. Bottom surface and side pits up to a height of 30 cm will be treated @ 05(Five) Ltr. Chemical Emulsion per Sq. Mtr. of surface area.

2. Back fill earth in immediate contact with the foundation structure will be treated @ 7.5 Ltr.

per Sq. Mtr. of the vertical surface of substructure of each side.

3. Treatment of RCC foundations: Treatment should start at depth of 50 cm below ground level @ 7.5 Ltr. per Sq. Mtr.

4. Treatment of top surface of plinth filling: The top surface of the earth consolidated within

plinths wall shall be treated with Chemical Emulsion @ 05(Five) Ltr. per Sq. Mtr. of the surface before the sand bed or sub grade is laid.

5. Soil treatment along external perimeter of building: Earth along the external walls of the

building should be treated at an interval of 15 cm and to a depth of 30 cm exposing the wall surface. Chemical Emulsion will be poured along the wall @ 7.5 Ltr. per Sq. Mtr of vertical surface.

POST CONSTRUCTION TREATMENT The treatment comprises of drilling holes at the wall and floor junction level and filling it after pumping in sufficient quantity of chemical. This ensures a continuous chemical barrier for termites to make an entry and protect the treated structure. 1. Treatment to wall and floor junction:

Holes of diameter 12 mm (1/2" approx.) are drilled at approximately 30 cm (12 inches) intervals along the inner junction of wall and floor in the entire premise. Water based chemical will be injected under pressure into these holes, to create a barrier against termite.

2. Treatment to soil under floor:

If the subject premises on the ground floor and if cracks are noticed on the floor because of construction joints, expansion joints or shrinkage, the soil below floor needs to treated. Holes of 12 mm (1/2" approx.) dia 30 cm apart will be drilled along the cracks and water based chemical will be injected under pressure into these holes.

3. Treatment to wooden fixtures:

Holes of diameter 12 mm (1/2" approx.) will be drilled at the base of wooden works such as window frames; door frames etc. inset in the flooring and chemical will be injected. A oil based chemical will be sprayed on all the wooden work infested by termites within the premise.

4. Treatment to termite tubes:

Visible shelter mud tubes will be removed and the infested area treated with Water base chemical.

5. All the drilled holes will be sealed and made good using cement

b) Fire Stop System

Providing & Supplying Passive Firestop system using HILTI Mineral wool

board along with CP 670 coating of 1 mm DFT and CP 606 Firestop filler or

Equivalent system. Fire barrier coating of 1 mm thickness should be apply on

Mineral wood board (density min. 150 kg/cu. meter) and fill the remaining gap

around entrants with suitable filler of depth same as mineral wool panel

thickness to provide 2 hour fire rating on solid structure (wall- min. 80 mm,

floor- min. 150 mm thickness) when subject to test conditions of BS 476: part

20:1987 and after age testing to DafStb guidelines. Cables and cable tray

should be coated with above same coating up to minimum length of 300 mm to

prevent spread of fire. Fire barrier coating and filler should be approved to

international test standard like BS 476 and tested by FM, LPC, BRE, and

WFRC. For wall opening the Board system should be used on both sides of the

wall and for floor opening it should be used only on one side.

c) Fire Stop System

Providing and supplying versatile intumescent expanding foam CP 620 of

HILTI India Pvt Ltd.The product shall be tested for withstanding Zone 4

earthquake when tested in accordance with acceleration time history waveform

VERTEQII as per IEC 60068 and Telcordia Technologies GR-63-Core 2006-

03. The product shall be age tested for 30 years as per Dafstb and DIBT

standards. The product shall provide water tightness when tested for W rating

as per UL standards and shall be tested for providing a sound insualtion of 50

when tested in accordance with ASTM E 90. The product shall be tested and

approved by third party agencies such as UL, FM and LPCB. The product shall

bear the UL and FM approval logo on the packing.
