and doors). Complete plinth area of the building shall be measured in square mtr on

the basis of basement area of the building.

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. Itis 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 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 betreated @ 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 cmbelow ground level @ 7.5 Ltr. per Sq. Mtr.

4. Treatment of top surface of plinth filling: The top surface of the earthconsolidated 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 externalwalls of the building should be treated at an interval of 15 cm and to a depth of30 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 andfilling 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 abarrier against termite.

2. Treatment to soil under floor:

If the subject premises on the ground floor and if cracks are noticed on the floorbecause 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 bytermites within the premise.

4. Treatment to termite tubes:

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

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

TRIMIX

How to place high-quality durable Industrial floors the requirements on the quality ofIndustrials floors have rapidly become more exacting during the few years. The reason for

this is mainly the use of fork-left trucks and other modern transport equipment. The increasedwheel loads require higher compressive strength and wear resistance of the floor than before.

With increasing lift heights higher accuracy as to the fines of the floors becomes aprerequisite.

These demands of cause lead to a further checking of traditional floor placing methods and todevelopment of new building methods. The TREMIX Vacuum Dewatering Technique. Which

is described here satisfies these high quality requirements. In addition, this method offersseveral advantages .e.g. Lower manufacturing costs.

Traditional floor placing: several courses.

According to traditional floor placing methods, a base course is first placed. This base is thencovered with a topping. This topping, which may consists of one or several courses, must be

placed very carefully. Therefore, it is quite a hard work. The topping must have good bond tothe structural concrete if it is to function in operation and in traffic. Problems like break away

of the topping are usual on this type of floors.

In spite of similar initial materials, the physical properties of concrete and topping aredifferent. Both layer be have differently at varying temperature-weather-and environmentconditions. This may lead to stresses in the floor. For bimetals, such stresses are desirable but

not for industrial floors, as they cause separation of the topping from the base concrete,


23/118

23

cracking and finally breakaway. A repair is then inevitable Repairs are not only expensive butalso associated with costly interruptions in production and cause dust and noise problems.

Modern floors: single course.

The considerations to avoid the problems involved with traditional floor placing lead tomonolithic industrial floors. The structural concrete needs no topping.

The monolithic method is successfully used in road building since decades. Extensive

research and practical experience from the placing of thousands of kilometers of concreteroads have brought these up to their present high quality level. The Monolithic concrete roadsare placed with heavy building machines. Very stiff concrete consistency class K-1 with avery low water/cement ratio used. Road building owes its high quality to this technique.

The great weight of the machines and the hardly workable concrete do not however, ingeneral allow the used of this technique for industrials floors.

Monolithic industrial floors, which have the same high quality as concrete roads, are thereforenowadays-placed according go the TRIMIX Vacuum Dewatering Method.

The advantage of this method is that a plastic and easily workable concrete can be placed with

light equipment, and after that great part of the surplus water is extracted from the concrete,and the desirable quality y improvement is achieved.

The TRIMIX Vacuum Dewatering Method has been used with great success for high-qualityIndustrial floors for many years.

The use of the TRIMIX Vacuum Dewatering Method.

This method follows the well-known laws of concrete technology and construction. For full

utilization of the advantages of the advantages of the TREMIX Vacuum Dewatering system,the following points should be observed already at the planning stage.

Base

If the Industrial floors are placed directly on the ground, the base must have a sufficientbearing capacity. If necessary, frost protection layers are placed on free surfaces orappropriate filling materials for floors in halls or hangars.

At this work and also at the ensuing concrete placing careful attention should be paid to the

calculation of the expected traffic loads keeping in mind also those often-bigger ones, whichoccur during the construction work.

If industrial floors are placed as suspended floors, the usual conditions regarding formworkand static loads are valid.

Installations

The position of the pipes for water and drainage, heating, eclectics supply and telephones

must be fixed before concreting starts, so they not hinder the concreting work.

Through vacuum processing shrinkage is reduced by 50.75 % compared to that of normalconcrete. Correspondingly, Joint spacing can be increased on vacuum dewatered industrial

floors. Joint less bays 20x20 m are possible.)New condition for this is however that stabilityof the bars and the construction including reinforcement is calculated with regard to future

traffic loads.

Also on suspended floors the joint distance can be increased. At the execution, howeverattention must be paid to the stresses of the construction. The joints must be expansion joints


24/118

24

which give enough room for the movement of concrete. Expansion joints can as a rule belocalized on fixed bases for flat industrial floors.

Dummy joints are working joints, the placing of which is determined by daily production e.g.400 Sq.mt. at 20x20 m for heavy traffic the joints must be carried out as for highways withgrooved joints.

Contraction joints to of the slab thickness are cut afterwards. They give clear and stresses.Their construction is easier and cheaper than from removal their function faultless and

reliable.

SlopeConcrete floors can have star shaped or roof shaped slopes Roof shaped slopes preferable.

Separation layerBefore placing concrete on ground, a plastic sheet must be placed on the gravel or sand bed as

a separation layer for protection against humidity and water. It also works as a sliding layerwhich prevents concrete from sticking to the sub base and allows the working of the concrete,in order to avoid cracking.

This separation layer is not needed for suspended floors Concrete is placed directly on

ordinary from and special preparation are not necessary.

Reinforcement

Reinforcement depends on the static constructional demands on the floors. A careful

estimation of the expected traffic loads on the floor and the base is necessary.

Important:Vacuum concrete should be made according to standards DIN 1045 With regardto concrete quality you must not use so much water that it runs on its own into the for work.

Even if the excess water is then extracted during to vacuum treatment the quality of theconcrete would suffer. Therefore the exacting demands of the standard DIN 1045 should beobserved.

Admixture:A pre-test of the admixtures, if used is to the carried out on order to determine

their suitability for vacuum dewatering.

Standards: DIN 1045 is also valid for vacuum impermeability high frost resistance, high

resistance against chemical, high wear resistance is required, the prescriptions of paragraph6.5.7 of the standard are to be followed, even if vacuum dewatering improves these properties

further.

Quality:The improved properties of vacuum concrete can be proved by taking specimensfrom cores or 15 cm cubes. The cubes are made in a TTREMIX laboratory apparatus calledTM 1.

Work cycle according to the TREMIX Vacuum dewatering process.

The TREMIX Vacuum dewatering process has been developed in order to rationalize the

concrete work and to achieve high quality concrete floors.

This system is advantageous to anyone involved in buildings projects, to the designer as itmeans high quality and new aspects on the practical work, to a contractor trouble-from

application on sites, to estimating engineer noticeable cost savings and finally, to the end userdurability and maintenance costs.

Concreting according to DIV 1045 and leveling according to DIN 18.202


25/118

25

Concrete of consistency class K 2/K 3 (8-12 cm slump ) is placed either by pump crame skipor direct from concrete truck. Then follows poker vibration. The next step is leveling which is

carried out with TREMIX surface vibrator.

The surface vibrator, available in lengths of 3 to 12 m. consists of a light alloy double beam.The beam is provided with tensioning road to prevent deflection. The TREMIX surfacevibrator leaves a concrete surface within the tolerance region of DIN 18.202 line 6 or 7.

Vacuum dewatering process

The purpose of vacuum processing is the removal of surplus water forms the concrete toprovide quicker setting & earlier maximum strength properties. Vacuum dewatering takesplace immediately after the screeding operation.

Upon the surface of the wet concrete is placed a filler pad consisting of two layers. Thebottom layer is contract with the concrete is the fine nylon cloth to act as filler. The upper

layer consists of a special type of plastic net & acts as a water duct. Finally the top coverconsisting of a light plastic sheet is placed over the filler pad projecting slightly outside on allsides. The border of the top cover rests directly upon the wet concrete to produce an airtightseal.

The suction met is connected with suction houses to a vacuum pump. the normal atmosphericpressure in the pump is reduced by 90% & 90% of the atmospheric pressure compresses the

concrete.

Concrete is submitted to a pressure of

Air pressure .1N / mm2Depression .01N/mm2

________= Effective pressure .09 N/ mm2

This pressure of about 9000 kp/m2 compresses the concrete & compacts the aggregates. Atthe same time the excess water which not necessary for the hydration process of the cement is

extracted from the concrete & consciously discharged with the air.

Apart from normal compaction through vibration, static compaction takes place duringvacuum dewatering with ensuring reduction w/c ratio. The initial w/c/ ratio is reduced by 10to 20%. This explains the noticeable improvement s of the concrete properties achieved

through vacuum dewatering.

Vacuuming time is about 1 to 2 min. per cm concrete thickness depending on the particleshape in the mix. M250

One vacuum pump with two suction met can dewater 50 to 60 m2. A 20 cm thick concreteslab takes about 30 min. dewater. Accordingly a normal daily production rate is about 400

m2.

Mode of Measurement: The measurement shall be in Sq. Mt.

Construction Operations

Preparation of sub grade:Immediately prior to the laying of sub-base, the sub grade

already finished to Clause 7.1 shall be prepared by removing all vegetation and other

extraneous matter, lightly sprinkled with water if necessary and rolled with two passes

of 80 100 kN smooth wheeled roller.

Spreading and Compacting: The sub-base material of grading specified in theContract shall be spread on the prepared sub grade with the help of a motor grader ofadequate capacity, its blade having hydraulic controls suitable for initial adjustment and

for maintaining the required slope and grade during the operation or other means asapproved by the Engineer.

When the sub-base material consists of combination of materials mentioned in Clause

7.3.2, mixing shall be done mechanically by the mix-in-place method.

Manual mixing shall be permitted only where the width of laying is not adequate for

mechanical operations, as in small-sized jobs. The equipment used for mix-in-place

construction shall be

a rotavator or similar approved equipment capable of mixing the material to the desired

degree. If so desired by the Engineer, trial runs with the equipment shall be carried out

to establish its suitability for the work.

Moisture content of the loose material shall be checked in accordance with IS: 2720

(Part 2) and suitably adjusted by sprinkling additional water from a truck mounted or

trailer mounted water tank and suitable for applying water uniformly and at controlled

quantities to variable widths of surface or other means approved by the Engineer so that,at the time of compaction, it is from 1 per cent above to 2 per cent below the optimum

moisture content corresponding to IS: 2720 (Part 8). While adding water, due allowance

shall be made for evaporation losses. After water has been added, the material shall be

processed by mechanical or other approved means like disc harrows, rotavators until the

layer is uniformly wet.

Immediately thereafter, rolling shall start. If the thickness of the compacted layer does

not exceed 100 mm, a smooth wheeled roller of 80 to 100 kN weight may be used. For a

compacted single layer upto 225 mm the compaction shall be done with the help of a

vibratory roller of minimum 80 to 100 kN static weight with plain drum or pad foot-

drum or heavy pneumatic tyred roller of minimum 200 to 300 kN weight having a

minimum tyre pressure of 0.7 MN/m2 or equivalent capacity roller capable of achieving

the required compaction. Rolling shall commence at the lower edge and proceed

towards the upper edge longitudinally for stretches of unidirectional cross falland super-

elevation, and shall commence at the edges and progress towards the centre for stretches

having cross fall on both sides.

Each pass of the roller shall uniformly overlap not less than one-third of the track made

in the preceding pass. During rolling, the grade and crossfall (camber) shall be checked

Construction Operations

Preparation of base:

Prior to laying of the wet mix macadam base the granular sub-base already laid shouldbe prepared by removing of extraneous material, lightly sprinkled with water and rolledwith two passes of 80 100 kN smooth wheeled roller.

Provision of lateral confinement of aggregates:

While constructing wet mix macadam, arrangement shall be made for the lateralconfinement of wet mix. This shall be done by lying materials in adjoining shouldersalong with that of wet mix macadam layer and constructing the adjoining shoulder with

approved material along with that of the wet Mix Macadam layer.

Preparation of mix:

Wet Mix Macadam shall be prepared in an approved mixing plant of suitable capacity

having provision for controlled addition of water and forced/positive mixingarrangement like pugmill or pan type mixer of concrete batching plant. For smallquantity of wet mix work, the Engineer may permit the mixing to be done in concrete

mixers.

Optimum moisture for mixing shall be determined in accordance with IS:2720 (Part-8) after replacing the aggregate fraction retained on 22.4 mm sievewith material of 4.75 mm to 22.4 mm size. While adding water, dueAllowance should

be made for evaporation losses. However, at the time of Compaction, water in the wetmix should not vary from the optimum value by more than agreed limits. The mixed

material should be uniformly wet and no segregation should be permitted.

Spreading of mix:

Immediately after mixing, the aggregates shall be spread uniformly and evenly upon the

prepared sub grade/sub-base/base in required quantities. In no case should these be


31/118

31

dumped in heaps directly on the area where these are to be laid nor shall their haulingover a partly completed stretch be permitted.

The mix may be spread either by a paver finisher or motor grader. For portions wheremechanical means cannot be used, manual means as approved by the Engineer shall beused. The motor grader shall be capable of spreading the material uniformly all over the

surface. Its blade shall have hydraulic control suitable for initial adjustments andmaintaining the same so as to achieve the specified slope and grade.

The paver finisher shall be self-propelled, having the following features:

i) Loading hoppers and suitable distribution mechanism

ii) The screed shall have tamping and vibrating arrangement for initial compactionto the layer as it is spread without rutting or otherwise marring the surface

profile.

iii) The paver shall be equipped with necessary control mechanism so as to ensurethat the finished surface is free from surface blemishes.

The surface of the aggregate shall be carefully checked with templates and all

high or low spots remedied by removing or adding aggregate as may be required. The

layer may be tested by depth blocks during construction. Nosegregation of larger and fine particles should be allowed. The aggregates as Spread

should be of uniform gradation with no pockets of fine materials.

Compaction: After the mix has been laid to the required thickness, grade and cross

fall/camber the same shall be uniformly compacted, to the full depth with suitable roller.

If the thickness of single compacted layer does not exceed 100 mm, a smooth wheel

roller of 80 to 100 kN weight may be used. For a compacted single layer upto200 mm,

the compaction shall be done with the help of vibratory roller of minimum static weight

of 80 to 100 kN or equivalent capacity roller. The speed of the roller shall not exceed 5

km/h

In portions having unidirectional cross fall/super elevation, rolling shall commence fromthe lower edge and progress gradually towards the upper edge. Thereafter, roller should

progress parallel to the centre line of the road, uniformly over-lapping each preceding

track by at least one third width until the entire surface has been rolled. Alternate trips

of the roller shall be terminated in
