8.1.4 The quantity of mixing water shall be limited to that necessary for handling and placing. The patching material shall be thoroughly mixed to the extent that i t is the

stiffest consistency that will permit placing.

9.1.5 The area to be patched and a band at least 150 mm wide surrounding it shall be dampened to prevent adsorption of water from the patching mortar. After surface water has evaporated from the area to be patched, an approved bonding agent shall

be well brushed into the prepared surface. The premixed patching mortar shall be thoroughly consolidated into place, struck off so as to leave the patch slightly higher than the surrounding surface and left undisturbed for at least 1 hour to allow for some

initial shrinkage before being finally finished. The patched area shall be kept damp for

7 days.

9.1.6 Proprietary compounds may be used in lieu of, or in addition to, the foregoing patching procedures. Such compounds must be used strictly in accordance with the manufacturer’s recommendations. Specific approval from the barrier manufacturer

shall be obtained before proprietary compounds are used for patching. These materials shall be compatible with the barrier system and the concrete, and not

interfere with good adhesion between the two.

9.1.7 Fins, protrusions or similar irregularities projecting from the concrete surface shall be removed back to the surface by chipping, bush hammering, needle gunning, or

wire brushing. Care shall be exercised to obtain a reasonably planar surface for application of the barrier system. Sharp offsets in the surface, such as those caused by formwork misalignment, shall be mechanically abraded to provide gradual and

smooth transitions between the offset surfaces. 9.2 Stopping or Rerouting of Water


Page | 56

9.2.1 The Contractor shall employ a suitable method of repair to stop any seepage or flow of water into or through the concrete structure prior to application of the barrier

system. The method of repair shall depend on the type of defects present in the concrete and the source of water.

9.2.2 Stopping or rerouting water at the source 9.2.2.1 Excavation outside the structure and installation of temporary site drainage shall

be considered. 9.2.3 Stopping water on surface not in contact with the source

8.2.3.1 Water ingress though a crack, hole or porous area may be stopped on the side

opposite the water-source

9.2.3.2 The use of cementations quick-setting materials shall be considered as temporary

water stops only until permanent surface repairs can be made. Quick-setting mixes

with a chloride ion content exceeding the limits given in the Concrete Work Specification shall not be permitted.

9.2.3.3 Epoxy injection can be either a temporary or permanent repair depending on the following conditions. If the crack is non-moving, epoxy injection can be permanent

repair. If cracks move enough to destroy adhesion between the concrete and the epoxy, the repair shall be considered temporary. The crack to be treated shall first be temporarily sealed with an epoxy resin paste to withstand injection pressures. A low

viscosity epoxy adhesive shall then be injected under pressure through ports established in the surface seal. Qualified and experienced applicators shall be used for this work.

9.2.3.4 Chemical grouts can be effective on a permanent basis if not allowed to dry out. Small grout up to 25 mm in diameter shall be drilled through the concrete wall in the

area of the leaks. The Contractor shall undertake approved precautionary measures during drilling to detect and avoid damage to embedded reinforcement. A low viscosity (2cps), 2-part plastic monomer solution shall then be pumped through

inserted pipes to saturate the soil and form a seal upon hardening. Qualified and experienced applicators shall be used for this work.

9.2.4 Rerouting water on surface not in contact with the source 9.2.4.1 Each crack through which water is flowing shall be covered with a small hollow

enclosure to form a temporary channel. A hollow enclosure may be produced from wire mesh formed in a semicircle with cementations quick-setting material as infill. Enclosures shall be connected together to route the water to a central location. Once

the flow of water has been controlled, other permanent repair methods shall be employed.

9.3 Surface Cleaning

9.3.1 Generally, surfaces shall be dry and must be newly exposed concrete, free of chemical contaminants and loose, weak or unsound materials.

9.3.2 Pre cleaning

9.3.2.1 The Engineer shall inspect the concrete surface to determine the necessity for

pre cleaning. If the surface is heavily contaminated with oil and grease, pre cleaning


Page | 57

is required prior to blast cleaning. Solutions of caustic soda or trisodium phosphate or proprietary detergents specially formulated for use on concrete may be employed for

this purpose. If used, caustic soda solution shall be in a 10/90 dilution ratio. Detergents shall be heavy-duty, non-ionic type. They shall be applied by vigorous scrubbing with a brush or power broom, followed by flushing with water to remove all

traces of both the detergent and the contaminant. Litmus or pH paper shall be used on the wet surface to check the adequacy of flushing. The flushed surface shall be either neutral or slightly alkaline. Solvents are liable to dissolve the material and

spread the contamination over a larger area, and shall not be used as a cleaning agent for this reason.

9.3.3 Mechanical cleaning

9.3.3.1 Scarification by a mechanical impacting device on concrete surfaces may be used to remove thick overlays of dirt or weakened material. Aggregate weakened by scarification shall then be removed by water blast or sand blast. Grinding may be

employed when small areas are to be cleaned or when the cleaned surface must be smooth.

9.3.3.2 Blast or abrasive cleaning shall be used to remove laitance, dirt, efflorescence and weak surface material. The Contractor may select either wet sandblasting or high pressure water jetting procedures for this purpose, subject to compliance with local

building or environmental bylaws and regulations governing the use of such methods, and also to field tests to verify the effectiveness of the method for removing weak surface material. Abrasive cleaning methods other than sand-blasting may be

considered for use provided that the surface is not contaminated by the abrasive used. The compressed air used for sandblasting shall be clean and free of oil particles, and requires the air compressor to be equipped with efficient oil and water

traps. The Contractor shall ensure that clean water is used for wet blast cleaning, and shall make adequate provisions to collect and remove effluent from the Site. The surface shall be abraded to the extent that small aggregate particles are exposed. If

the surface of concrete is weak, more material shall be removed. 9.3.4 Acid etching

9.3.4.1 Acid etching shall be employed at areas where no alternative means of cleaning

are possible. The etching operation shall be performed by persons experienced in

such application.

9.3.4.2 The acid used for etching shall be a 10/90 to 20/80 dilution ration of commercial grade phosphoric acid in water solution applied at the rate of 1.0 square meter per litre. The use of hydrochloric acid shall not be permitted on account of the chloride

constituent. For large areas, low pressure automatic spray equipment shall be used to apply the acid solution. For small areas, plastic sprinkling cans can be used for dispensing the acid solution. A stiff bristle street broom, brush, or similar implement

shall be used to spread the acid solution uniformly over the surface. After the foaming action of the acid has subsided, normally in 3 to 5 minutes, the surface shall be thoroughly flushed with water while scrubbing with stiff bristle or wire brushes to

remove the salts formed by acid reaction and to dislodge loose particles. A second treatment may be necessary to ensure an absolutely clean surface.

9.3.4.3 The adequacy of the flushing system shall be checked at several points within the cleaned area by placing litmus or pH paper on the wet surface to determine whether


Page | 58

the acid has been completely neutralised. If flushing is adequate, the surface shall be allowed to dry. When forced drying is necessary, heat may be applied or dry, oil-free

air may be blown over the surface. 9.4 Tests for surface Quality

9.4.1 Prior to barrier application, the adequacy of surface preparation shall be tested on

the basis of cleanliness, dryness, adhesion quality, and the effects of concrete patching compounds and form release agents. Applicable test procedures are

described below.

9.4.2 Cleanliness of surface

(a) Dusty condition: Wipe the surface with a dark cloth. If a white powder is on the cloth, the surface shall considered to be too dusty and unsatisfactory.

(b) Oily condition: Sprinkle water on the dried concrete surface. If the water spreads out immediately instead of standing as droplets, it shall be considered that the surface is not contaminated by oils or dust

(c) Acid condition: Use pH paper to determine the acidity at the concrete surface. A

pH below 4 shall be considered unacceptable. 9.4.3 Dryness of surface

9.4.3.1 Moisture content shall be considered excessive if moisture collects at the bond line between the concrete and the barrier material. Generally, a test for surface

moisture content shall be conducted before the start of each day’s operation.

9.4.3.2 Moisture content shall be evaluated qualitatively by taping a 1.2 m* 1.2 m clear,

polyethylene sheet to the concrete surface and determining the time required for moisture to collect on the underside of the polyethylene sheet. The ambient conditions, i.e. sunlight, temperature and humidity, during test shall simulate, as much

as practical, the conditions during application of the barrier. The time for moisture to collect shall be compared with the time for adhesion development is less than that required for moisture to collect, the concrete shall be considered adequately dry.

9.4.4 Strength of surface when laitance is present

9.4.4.1 The presence of laitance shall be tested by scraping the surface with a putty knife. If a lose powdery material is observed, excessive laitance is considered present

and shall be removed by mechanical means prior to laying of barrier.

9.4.4.2 Patch tests for surface strength shall be carried out to check the peel adhesion of the barrier system and to provide an indication whether surface cleanliness and

dryness are satisfactory. Patch tests shall be conducted before the start of and during barrier installation at a frequency to be determined by the Engineer. The ambient conditions, i.e. sunlight, temperature and humidity, during test shall simulate, as much

as practical, the conditions during actual application of the barrier. If the results of the tests are not satisfactory for any reason, the Engineer may order further tests to be carried out. Conversely, the Engineer may reduce the rate of sampling if consistent

high quality of workmanship has been well established.

9.4.4.3 The Contractor shall obtain from the barrier manufacturer the recommended procedure for the peel adhesion test, otherwise the following method shall be adopted. An area of clean and dry concrete, which should simulate as much as

practical the conditions existing during application, shall be selected and a 0.6m x 0.6m barrier panel applied in accordance with the manufacturer’s recommendations.


Page | 59

One edge of the barrier panel shall be secured to load a application device capable of applying a uniform peeling force along the panel edge. After adhesion has been

allowed to developed, the panel shall be peeled from the concrete at a 90 degree angle, starting from panel edge. The force required to initiate peeling along the length of panel edge shall be measured for compliance with the manufacturer’s

recommendation and this specification. 10.0 WATERPROOFING UNDER BASEMENT SLABS & SLABS IN CONTACT WITH

SOIL

10.1 Material

10.1.1 HORIZONTAL AREA: The barrier material shall be 4mm the APP modified membrane of MAXIPRO or equivalent for horizontal areas and should be self-finished with mineral granules and weight 5.5 kg/sqmt. It should be reinforced with 180gsm

polyester mat to get tensile strength of minimum 850 (longitudinal) / 575 ( transverse) N5 cm laid loosely on finished pcc surface with a base coat water based emulsion with a minimum overlap of 100mm. Care should be taken to do proper welding by

heating torch.

Vertical area: All as above except mineral granules with a minimum weight of

4.5Kg/m2 with solvent based primer as adhesive @ 250gm/sqmt.

This membrane on floor shall be protected using BITUPROTECT which is a high strength

impact resistant protective board to receive raft rebar. 10.1.2 In the absence of test certificates, the Contractor shall carry out tests to verify

quality of material. Tests shall be carried out in accordance with the appropriate ASTM procedures or approved equivalent.

10.2 Method of Construction

10.2.1 Generally, the application procedures shall be consistent with the manufacturer’s recommendations.

WATER PROOFING METHODS:

1. Basement raft and Terrace water proofing method of works:

Water proofing with 4 m thick APP modified membrane “Maxipro” with 180 gsm polyester

reinforced membrane laid loosely over the base concrete with a coat of water based emulsion with a overlap of 100 mm. The overlap portion shall be torch welded.

Note: The surface to be treated should be reasonably smooth and clear of damaging objects, free from slurry and water. The base layer should be evenly plastered smooth to receive the membrane.

The base layer should be primed with emulsion to receive the membrane. After the priming coat roll of membrane shall be rolled over the flat area to the required length and

all the overlaps shall be minimum of 100 mm. All the overlaps shall be flame torched. For horizontal surfaces of treatment: A rich mix of screed concrete M25 grade 20 to 30

mm thick shall be laid over the membrane in the horizontal surfaces to protect the membrane from reinforcement during placing.


Page | 60

For Vertical surfaces of treatment: Extruded polystyrene protection board 20 mm thick shall be fixed over the membrane in vertical surfaces to protect the membrane from

reinforcement during placing. In case of non – availability if extruded polystyrene protection board, bituminous protection board 3 mm thick may be used with necessary prior approval of the architect /owner.

Work shall be carried out as per the approved method of waterproofing accepted by the architect, work shall be guarantee for five years against leakage and guarantee shall be

provided in the form of guarantee bond as per the approved format. 2. Water proofing method for Lift pits, Toilet sunken slabs U.G.Sump, STP tank:

The Waterproofing to the above areas shall be carried out using Penetron slurry as per

the procedure indicated below: Since the PENETRON requires moisture to initiate the crystalline waterproofing process,

all concrete, whether fresh or old, must be saturated with water.

The concrete surface must be a minimum of 24 HOURS (ONE DAY) old before application of the PENETRON SLURRY coating treatment.

For normal surface conditions, the coverage rate for each PENETRON coat is 0.7 Kg/sqm.

1. The concrete surface to be treated must be clean and free of laitance, dirt, film, paint,

coatings or other foreign matter. 2. If surface is too smooth (where steel forms are used) or if surface is covered with

excess form oil or other foreign matter, the concrete should be cleaned thoroughly with wire brush or water jet.

3. Rout out cracks, faulty construction joints and other structural defects to a depth of 1.5 inches (37 mm) and a width of 25 mm

4. Apply a brush coat of Penetron slurry Concentrate in cavity and allow drying for 10 minutes.

5. Against a direct flow of water (leakage) or where there is excess moisture due to seepage, use PENEPLUG first and followed by a brush of PENETRON SLURRY.

PENETRON SLURRY requires a saturated substrate and a damp surface. Concrete surfaces, therefore, must be thoroughly saturated with clean water prior to the application so as to aid the proper curing of the treatment and to ensure the growth of the crystalline

formation deep within the pores of the concrete. Remove excess surface water before the application. If concrete surface dries out before application, it must be re-wetted.

Mixing of PENETRON SLURRY COAT

(i) Mix PENETRON with clean water only (water that is free of salt and other

deleterious materials).

(ii) Mix clean water into the PENETRON SLURRY powder with a paddle on a slow speed electric drill (250 RPM) or with other equipment that ensures adequate mixing. For small jobs, PENETRON SLURRY may be mixed by gloved hand.


Page | 61

(iii) Be sure that the quantity mixed can be applied within 20 minutes. As the mixture thickens, stir frequently but do not add water.

(iv) Mix PENETRON SLURRY powder with clean water to a creamy consistency For

Brush Application 2.5 parts powder to 1 part water. Application of PENETRON SLURRY COATING

Apply PENETRON SLURRY with a semi-stiff nylon bristle brush. Do not apply PENETRON with a trowel, roller, paintbrush or paint sprayer.

The PENETRON coating must be uniformly applied and should be less than 1.25 mm thick. A thicker coating can cause curing difficulties, especially in warm weather.

Second coat PENETRON Concentrate should be applied after the first coat has reached an initial set but while it is still "green" (less than 48 hours). Light pre-watering between coats may be required due to drying.

In hot weather it is advisable to apply PENETRON either early in the morning or late in the day. This will prevent the PENETRON coating from drying out too quickly. Curing

shall be misty fog spray of clean water must be used for curing the PENETRON treatment. Curing should begin as soon as the PENETRON has set to the point where it will not be damaged by a fine spray of water.

3.0 Construction joint treatment:

Providing treatment to construction joints in basement raft, walls etc, to be carried out as

per the manufacturer specification and as detailed in technical specification complete.Work shall be carried out as per the approved method of waterproofing accepted by the architect, work shall be guarantee for five years against and leakage and

guarantee shall be provided in the form of guarantee bond as per the approved format. Providing and applying Penebar SW 45 Type A water stop of expansive nature at

(c) For longitudinal reinforcing bar in a beam not less than 25 mm, or less than the

diameter of such rod or bar. (d) For tensile, compressive, shear or other reinforcement in a slab not less 13

mm., nor less than the diameter of such reinforcement and

(e) For any other reinforcement not less than 13 mm, nor less than the diameter of such reinforcement.

Item 9 of TENDER – Strengthen the columns by RCC jacketing Generally except where they are varied by the requirements of this

specification due provision of Indian standard specification IS-456-2000 for plain and reinforced concrete and IS –432 part I & II for mild and medium tensile steel bars and hard drawn steel wire for concrete reinforcement and any other relevant IS applicable

together with the latest amendments shall be held to be incorporated in this specification. It shall be intent of these specifications to ensure that all concrete placed at various location of the job should be durable, strong enough to carry the design

loads; it should wear well and practically be impervious to water. It should be free from such defects as shrinkage cracking and honey combing.

Proportioning the Mix: In ordinary concrete excluding controlled concrete proportion of cement to fine and coarse aggregate shall be as specified in the respective items and shall be

accurately measured as in. table “A” below. These proportions are based on assumption that the aggregates are dry. If aggregates are moist, allowance shall be made for bulking in accordance with IS- 2386. Allowance shall also be made for

surface water present in aggregate when computing water content. Surface water present shall be determined by one of field methods described in IS: 2386 (part III) In the absence of exact data the amount of surface water may be estimated from the

values given in table “B” below. Mixing:

Concrete mix shall be mixed in an approved mechanical mixer. The mixer and the mixing platform shall be suitably protected from wind and rain. Aggregate shall be accurately measured out in boxes and mixed dry along with cement, water shall be

added in measured quantity and mixing shall be continued until there is a uniform distribution of the materials and mass uniform in colour and consistency but in no case shall the mixing be done for less than 2 minutes.

When hand mixing is permitted with the approval of the Consultants it shall be carried out on a watertight mixing platform and care shall be taken to ensure that mixing is continued

until the mass is uniform in colour and consistency.


Page | 117

Consistency: Quantity of water for making reinforced concrete shall be sufficient so as to

ensure that concrete shall surround and properly grip all the reinforcement. The best consistency shall be that which will flow sluggishly without flattening out and without separation of coarse aggregates from the mortar. The degree of plasticity shall depend

on the nature of work and atmospheric temperature and whether the concrete is vibrated or hand compacted. The slumps shown in table “C” on relevant TENDER page obtained by the standard slump test carried out in accordance with the procedure laid

down in IS 1199-1959 shall be adopted for different types of works. Admixtures:

The use of admixtures may be allowed as specified in the respective items and shall be accurately measured by measuring jar only.

Transporting: Concrete shall be conveyed from the place of mixing to the place of final deposit as rapidly as practicable by methods which will prevent segregation or loss of any of the

ingredients. If segregation does occur during transport, the concrete shall be remixed before being placed. In no case more than 30minutes shall elapse between mixing and consolidation in its position.

Placing & Compacting: Concrete shall be placed in layers of suitable thickness or in strips and compacted

before initial setting commences and should not be subsequently disturbed. Method of placing shall be such as to preclude segregation and as far as practicable the placing shall be continuous. Special care shall be taken in accordance with IS-456 while lying

concrete under extreme weather. Concrete shall be thoroughly compacted during the operation of placing and thoroughly worked around the reinforcement, embedded fixtures and spaded, against concerns of the form work and by punning, rodding,

mechanically vibrating or by any other approved means. In addition form work shall be tapped lightly by using wooden mallet at the pouring head. The number and type of vibrator to be used shall be subject to the approval of Consultants and in general

immersion type vibrators shall be used. External vibrators shall also be used whenever directed.

The intensity and duration of vibration shall be sufficient to cause complete settlements and compaction without any stratification of successive layers or separation of ingredient or formation of laitance. Vibrator shall be inserted vertically in the concrete at

points not more than 45 cm. apart and withdrawn very slowly when air bubbles no longer come on the surface. Over vibration or vibration of very wet mixes is harmful and should be avoided. Care shall be taken to utilise the vibrator only to compact the

concrete and not to spread it. Sufficient number of reserve vibrators in good working condition shall be kept on hand at all times, so as to ensure that there is no slackening or interruption in compacting.

Curing: Concrete shall be carefully protected during first stage of hardening form harmful

effects of excessive heat, drying winds, rain or running water. It shall be covered with a layer of sacking, sand, canvas, Hessian or similar absorbent materials and kept constantly wet for five days from the date of placing of concrete.


Page | 118

Form Work:

The form work shall conform to the shape, lines and dimensions as shown on the drawings and be so constructed as to remain sufficiently rigid during the placing and compacting of the concrete and shall be sufficiently watertight to prevent loss of cement

slurry from the concrete. Form work or centering shall be constructed of steel or timber and adequately designed to support the full weight of wet concrete with deflection and retain its form during laying, ramming and setting of concrete. Timber used shall be

properly seasoned so as to prevent deformation when wetted.

All props shall be straight and of full height and no joints shall be allowed. Props shall

be braced with thin bamboos or wooden battens and where additional staging is necessary extra care shall be taken to use bigger diameter props with bracing at 4 or 5 levels. All props shall be supported on sole plates and double wedges. At the time of

removing props these wedges shall be gently eased and not knocked out. All rubbish, chippings, shavings and saw dust shall be removed from the interior of the

forms before the concrete is placed and the form work in contact with the concrete shall be cleaned and thoroughly wetted or treated with non-sticking mineral oil or any other approved material. Care shall be taken that oil or such approved material is kept out of

contact with the reinforcement. All form work shall be removed without shock or vibration and shall be eased off

carefully in order to allow the structure to take up its load gradually. Forms shall not be disturbed until concrete has adequately hardened to take up superimposed load coming on it and in no circumstances shall forms be struck until the concrete reaches strength

of at least twice the stress to which the concrete may be subjected at the time of striking.

In the normal circumstances (generally where temperatures are above 21 degrees centigrade) and where ordinary cement is used, forms may be struck after expiry 48 hours or as may be directed.

Strength: Concrete mixed in the proportion desired shall have compressive strength after

placing, not less than the following;-

S.No Concrete Mix Minimum compressive

Strength @ 7 days Minimum compressive Strength @ 28 days
