Anti termite treatment work procedure

Anti termite treatment work procedure

Anti Termite therapy in Existing Building

1. सामान्य / General

This pamphlet is ready in accordance with IS: 6313 (Code of Practice for Anti Termite Measures in Buildings Part 3 Treatment in Existing Buildings).

According to their habits, termites may be divided into two well-defined teams.

(A) Subterranean or floor nesting termites
(B) Non-subterranean or wooden nesting termites

A – Subterranean or floor nesting termites

• Are most damaging.
• Mainly liable for the harm to be triggered in constructing.
• They require moisture to maintain their life.
• They construct tunnels between their nest and supply of meals by coated runways.
• These coated tunnels present humid circumstances and darkness vital for his or her motion and for sustaining contact with earth
• The subterranean termites enter a constructing from floor stage, below the inspiration, working
their approach upwards by flooring, destroyed all earlier than them.

B – Non-subterranean or wooden nesting termites
This includes of

• Dry wooden and damp wooden termites.
• Dry wooden termites, which predominate, are in a position to reside even in pretty dry wooden and with no
contact with soil.

4. उऩचार की ऩद्धनत / Procedure of therapy:
Procedure of Treatment consist three elements i.e.
(i) Inspection
(ii) Extermination of termite
(iii) Preventive measures to be adopted.

(I) Inspection:

 Before endeavor any kind of therapy, a thorough inspection shall be product of the infestation within the constructing with a view to decide the extent to which it has unfold, and the routes of entry of termites into the constructing.

 A research of construction of the inspiration and the floor flooring helps to find out the routes of entry of termites from the soil and in addition in deciding the mode of therapy.

• They often assemble nests inside massive dimensional timbers comparable to rafters, posts, door and window frames, and so on. which they destroy, if not speedily exterminated. However, they’re not as prevalent and customary as subterranean termites.

Once the termites have an ingress into constructing, they carry on multiplying and destroy the picket and cellulosic supplies.

Periodic inspection and management measure are probably the most necessary steps in checking termite harm in
constructing.

2. उऩयोगी उऩकरण/ Equipment used:

Following tools and instruments are used for anti termite therapy:-
• Pressure Gun
• Power drills of various sizes and dia
• Sharp knife
• Safety tools
• Flash gentle and so on.

3. उऩयोगी रसायन/ Chemical used:

Chemicals talked about in Table -1 could also be used:-
• In water emulsion for soil therapy in an effort to defend a constructing from termite assault.

• In Mineral Oil or Kerosene for therapy of wooden to guard from termite assault.

 The steadiness chemical of 0.5 litre per working metre shall then be used to deal with the backfill earth as it’s returned to the channel directing the spray towards the wall floor.

 If there’s a concrete or masonry apron round the constructing, roughly 12 mm diameter holes shall be drilled as shut as potential to the plinth wall at 300 mm aside, deep sufficient to attain the soil under, and the chemical emulsion pumped into these holes to soak the soil under at a price of two.25 litre per linear metre.

Note :
 In soil which don’t enable percolation of chemical compounds to the specified depth, the uniform dispersal of the chemical to a depth of 300 mm shall be obtained by suitably modifying the mode of therapy relying on the positioning situation.

 The dosage of two.25 litres per linear metre shall nonetheless stay the identical.

 The therapy described in above applies to masonry foundations. In the case of RCC basis, the soil (backfill earth) involved with the column sides and plinth beams alongside the exterior perimeter of the constructing shall be
handled with chemical on the price of seven.5 l/m2 of the vertical surfaces of the construction.

Anti termite treatment work procedure 

 To facilitate this therapy, trenches shall be excavated equal to the width of a shovel exposing the perimeters of the column and plinth beams as much as a depth of 300 mm or as much as the backside of the plinth beam if this stage is much less than 300 mm.

 The chemical shall be sprayed on the backfill earth as it’s returned in to the ditch directing the spray towards the concrete floor of the beam of column because the case could also be.

(c) Treatment of soil below flooring:

The factors the place the termites are prone to search entry by the ground are the cracks on the (II) Extermination of termites in constructing:

 This operation shall be carried out in a thorough method, in search of the termites of their hideouts, comparable to ceilings behind picket panelling, inside electrical wiring battens, conduits, switchboards and comparable places.

 Recourse shall be taken to inject chemical compounds as given in (III) Preventive Measures under.

 All traces of termite tubes shall be eliminated so that any recent infestation, which could happen at a later date, could also be simply detected.

(III) Preventive Measures:

Preventive measures are as below:-

(a) Soil Treatment:
 The object of soil therapy is to determine chemical (poisonous) barrier between the termites in the soil and the constructing to be protected.

 Basically, it consists of treating the soil adjoining to or below the constructing with a chemical toxicant, which kills or repels termites.

 Water emulsions of one of many chemical given above shall be utilized in soil therapy and utilized uniformly on the prescribed price.

(b) Treatment alongside the out aspect of basis:

 The soil involved with the exterior wall of the constructing shall be handled with chemical on the price of seven.5 litres/m2 of the vertical floor of the sub-structure to a depth of 300 mm.

 To facilitate this therapy a shallow channel shall be excavated alongside and near the wall and chemical emulsion shall be poured at 1.75 litres per working metre of the channel.

 Roding with 12 mm diameter delicate metal rods at 150 mm aside shall be accomplished within the channel if
vital for uniform dispersal of the chemical to 300 mm depth from the bottom stage.

following places:
a. At the junction of the ground and partitions on account of shrinkage or the concrete;
b. On the ground floor owing to development defects;
c. At development joints in a concrete flooring, solid in sections; and
d. Expansion joints within the flooring.

 Chemical therapy must be offered inside the plinth space of the bottom flooring of the construction wherever such cracks are observed, by drilling vertically 12 mm holes on the junction of flooring and partitions, constructional and growth joints talked about above at 300 mm interval to achieve the soil under.

 Chemical shall be squirted into these holes utilizing a hand operated strain pump till refusal or to a most of 1 liter per gap. The holes shall be sealed. In common, the thought is to deal with the soil under the ground on the places of cracks with toxicants so that termites within the soil are denied entry by such cracks and opening within the flooring.
(d) Treatment to voids in masonry:

 Termites are identified to hunt entry into masonry foundations and work their approach up by voids in the masonry and enter the constructing at floor and higher flooring.

 The motion of the termites by the masonry partitions could also be arrested by drilling holes within the masonry partitions at plinth stage and squirting chemical into the holes to soak the masonry.

 The holes shall be drilled at a downward angle of about 450 ideally from either side of the plinth wall at roughly 300 mm intervals and emulsion squirted by these holes to soak the masonry utilizing a hand operated strain pump.

 The depth of drilled holes shall be elevated or decreased relying on the scale of the wall, for regular measurement brick wall that’s 230 mm thick wall, depth of drilled holes shall be 150 mm.

 This therapy shall even be prolonged to inside partitions having foundations within the soil  Holes shall even be drilled at important factors, comparable to wall corners and the place door and window frames are embedded within the masonry or flooring at floor.

 Emulsion shall be squirted by the holes until refusal or to a most of 1 litre per gap. The handled holes shall then be sealed.

(e) Treatment at factors of contact of wooden work:

All present woodwork within the constructing which is in contact with the ground or partitions and which is involved with the ground or partitions and which is infested by termites, shall be handled by spraying on the factors of contacts with the adjoining masonry with the chemical of focus given above by drilling 6 mm holes at a downward angle of about 450 on the junction of woodwork and masonry and squirting chemical into these holes until refusal or to a most of half a litre per holes. The handled holes shall than be sealed.

(f) Treatment of wooden work:

For the aim of therapy, woodwork could also be labeled as follows: a. Which is broken by termites past restore and want replacements b. Which is broken barely by termites and does not want alternative.

 The woodwork, which has already been broken past repairs by termites, shall get replaced.

 The new timber must be dipped or liberally brushed not less than twice with chemical compounds in mineral oil or kerosene as in above.

 All broken woodwork that doesn’t want alternative shall be handled as indicated under.

 Infested woodwork in body, cabinets, joints, purlins, and so on, involved with the ground or the partitions shall be supplied with protecting therapy by drilling holes of about 3 mm diameter with a downward slant to the core of the woodwork on the inconspicuous floor of the body.

 These holes must be atleast 150 mm centre to centre and may cowl your entire framework. One of the chemical compounds given above shall be liberally infused in these holes.

 If the wooden is just not protected by paint or varnish two coats of the chemical shall be given on all of the surfaces and crevices adjoining the masonry as per Para 3 above .

(g) Treatment {of electrical} fixtures:

 If infestation in electrical fixture (like change containers within the wall) is observed, covers of the change containers shall be eliminated and within such containers shall be handled liberally with 5 p.c Malathion dusting powder confirming to IS: 2568 or Chlorpyrifos Dust.

 The covers of the change containers shall be re fastened after dusting.

(h) Inspection:

Periodical inspection and vigilance are vital after finishing up the preventive therapy measures. It is important that observe up motion be maintained throughout subsequent humid and sizzling seasons if termites seem.

5. सुरऺ ा सार्धाननयाॉ / Safety Precautions
