Minimum recommended coverage rate is 1.5ltr/sqmtr in 2 coats to achieve a total DFT of 1.5mm. cured membrane shall exhibit: 1) Tensile strength ASTM D412 : >13 MPa 2)Tear Resistance ASTM D624C : 50 N/mm2 3) Shore A Hardness: 80 4)Elongation ASTM D412 : >450% 5 ( 1kg, CS 10 wheels, ASTM D 4060): 1.3 mg/1000 cycles 6) Service temperature: -20⁰C to +80⁰C 7) Resistant to Fire (EN13501-1)-Class E,d0 Manufacturers shall provide Certificate for Zero VOC, resistance to fire, 25 years life expectancy test certificate before the start of work. System includes supply , application and termination of coating all complete as per the manufacturer methodology. Clean the RCC slab/screed surface & wall for treatment by removing dust, dirt and layers of concrete over the surface. etc. by mechanical tools and wire brushing. Pressure grouting at construction joints or honeycombs with non shrink cementations grout by mixing shrinkage compensating admixture per bag of cement as per manufacturer’s recommendations. Prepare a side gola of 50X50 mm at the junction using polymer modified mortar. Providing and applying two component 100% solid content, hybrid polyurea /polyurethane membrane at coverage rate of 1.5ltr/sqmtr in 2 coats to achieve a total DFT of 1.5mm. It must be applied utilizing plural heated high-pressure spray proportioning machine/spray gun such as those manufactured by WIVA/Graco or equivalent spray proportioning equipment. Termination shall be done 300 mm above FFl by providing a groove cut of 30mm x 30mm & seal it with shrinkage compensated polymer modified mortar. Lay a 150 GSM geotextile layer to protect the coating from external damage on final coating before laying of screed concrete/final finish. It shall be applied as per manufactures specification. Rates are incl of surface preparation, grouting and chemical application only. (Rates for geotextile, protection plaster and final finishes such as screed or Brick bat filling for slope, china mosaic, tiles etc is not included in above item. It will be added as per EIC/clients requirements).

Providing and laying water proofing treatment on roofs of slabs by applying cement slurry mixed with water proofing cement compound consisting of applying: (a) after surface preparation, first layer of slurry of cement @ 0.488 kg/sqm mixed with water proofing cement compound @ 0.253 kg/sqm b) laying second layer of Fibre glass cloth when the first layer is still green. Overlaps of joints of fibre cloth should not be less than 10 cm. c) third layer of 1.5 mm thickness consisting of slurry of cement @ 1.289 kg/sqm mixed with water proofing cement compound @ 0.670 kg/sqm and coarse sand @ 1.289 kg/sqm This will be allowed to air cure for 4 hours followed by water curing for 48 hours. The entire treatment will be taken upto 30 cm on parapet wall and tucked into groove in parapet all around. d) fourth and final layer of brick tiling with cement mortar (which will be paid for separately. For the purpose of measurement the entire treated surface will be measured
