Surface preparation, Treating the cracks, cleaning of surface with the help of various equipment wire brush etc. and surface to be made dirt, oil and foreign particles free. Once the cleaning is done the site area will be washed with water to do away with micro fine particles from the water proofing area. All the area where water proofing job will be taken should be closed for normal foot trafic till. Complete curing of water proofing job. Repair of surface with polymer modified mortar cement/ water / fosroc Nitobond SBRIatex) All the cracks to be repaired and filled with polymer modified mortar any loose area present on the surface will also be repaired with PMM. Repair area will be requied to cure for one day before application of water proofing coating on te surface. Any pipe penetrations in the surface will be repaired and sealed with PMM. complete in all respect as per direction of Engineer in charge with in all leads and lifts.

Injection Nozzle Packing / grouting:- Drilling and fixing injection packers in RCC members for cementitious grouting, drilling holes in structural members at the intervals as per recommendation/requirement, cleaning the holes by air blower prior to fixing nozzles. Insert 12 mm dia, 50-75 mm long PVC or equivalent injection packers in cleaned holes with fast setting mortar like renderoc Plug or equivalent. Cut the packers by cut of wheel after completion of grouting without damaging structural elements. Injection grouting : Supplying and applying plasticised expanding grout admixture cementitious grouts Cebex 100 of Fosroc or equivalent having Chloride content- Nil as per BS: 5075 Typical unrestrained expansion of upto 1% in general. The admixture should be mixed @ 225 grams per 50 kg of cement, as per manufactures specification and as directed. Grouting of structural cracks (if any) : Injection Nozzle Packing @ cracks: drilling and fixing injection packers in RCC members for grouting drilling holes in structural members at the intervals 200 mm c to c as per site requirments, cleaning the holes by air blower prior to fixing nozzles. Pressure grouting unsing moisture insentive, low viscous epoxy grout conbextra EP 10(m) of Fosroc having mix density 1060 kg/ m3 comppressive 2). Strength (ASTM D695)-60 N/mm2 Tensile strength (ASTM c 304-97) -20 N/mm2 Flexural strength (BS 6319 part 4) -45 N/mm2 Finally cut the projected nozzle and seal with renderoc HS Extra with in all leads and lifts as pe the direction of Engineer in charge.

Water proof coating :- Providing and applying water proofing treatment to sound, moisture free concrete surface using Bursh bond RFX Grey manufactured by Fosroc chemicals india PVT. Ltd and applied by Fosroc authorised applicator. Welt cleaned, dry and leveled concrete surface shall be primed with Nitobond SBR Late (diluted with water in a ratio of 1 part SBR Latex : 4 part water :5 part cement) applied at coverage of 10 sqm / Litre (after dilution) following by application of Brushbond RFX Grey @ recommended consumption of 12-14 sqm / Pack for 1 mm thickness in two coats. Brushbond RFX is high performance Elastomeric cementitious water proof coating. It shall be applied in two coats at coverage rate of 12-14 sqm/ Pack to achieve a minimum WFT of mm.
