TREATMENT OF FLAT ROOFS P/A like BASF Masterseal 551 or equivalent, Minimum 1mm thick two component polymer modified elastomeric cementitious waterproofing coating of approved make, applied min two coats on the leveling screed concrete as per manufacturer's specification and conforming to the following parameters: (i) minimum adhesion strength of 1 N/mm2 (ii) minimum tensile strength of 1.8 N/mm2, sanwiching 45 GSMglas fiber mesh in between the 2 coats. (Make BSAF/Mapaei/Fosroc.)

Providing and applying integral crystalline slurry of hydrophilic in nature for waterproofing treatment to the RCC structures like retaining walls of the basement , water tanks, roof slabs , podiums, reservior, sewage & water treatment plant , tunnels /subway and bridge deck etc. prepared by mixing in the ratio of 5 :2 ( 5 parts integral crystalline slurry :2 parts water)for vertical surfaces and 3 :1 ( 3 parts integral crystalline slurry 1 part water ) for horizontal surfaces and applying the same from negative(internal)side with the help of synthetic fiber brush. The material shall meet the requirements as specified inACI-212-3r-2010 i.e by reducing permeability of concrete by more than 90% compared with control concrete as per DIN 1048 and resistant to 16 bar hydrostatic pressure on neagative side. The crystalline slurry shall be capable of self-heating of cracks up to a width of 0.50 mm. The work shall be carried out all complete as per specification and the direction of the Engineer-in-charge. (b) For horizontal surface one coat @1.10 kg per sqm.
