Providing and applying high performance an emulsified thixotropic Bitumen protective coating two coats (materials available in the market) on mosonry /concrete surfaces (at a coverage rate of 4m2/litre/coat) so as to get a black flexible tough barrier protective film having a DFT of minimum 125microns/coat and properties & ASTM test standards prescribed for the same over a priming coat of same Bitumen emulsion material as per the direction. The primer coat can be made in the site by diluting the same bitumen emulsion with 20% water and applied after cleaning thoroughly of all contaminants and making the surface free from oil, greese, wax, dirt,dust or any other foreign matter which might affect adhesion. The Waterproof coating should be applied in two coats & a Primer Coat to achieve the required thickness. (Total 3 coats including primer coat) Earth Work GF, Cellar part-Avg height = (3.3+0)/2=1.65 LMR1

Providing and applying two coats of elastomeric liquid water proofing membrane with resilient acrylic polymers (materials available) on wall surfaces without water dilution (ensuring a coverage rate of 4.2-4.5 m2/ Lit/two coats to achieve a DFT of upto 90-100 microns) over a single priming coat of self-penetrating acrylic white Primer having dilution with water in the ratio 2:1 and spreading at the rate of 8-10 sqm./Lit/coat for superior bonding and hiding. Before applying Priming coat, area must be pressure-washed with water jet having a minimum working pressure of 1400psi to remove all dirts, dust and waste products. Then, cut and open the non-structural hairline cracks less than 0.50mm in width upto 10mm with mechanical cutter and clean, moisten the surface cracks and fill the cracks with 'Crack-X-shrinkfree' crack filler by using a putty-blade. Apply two surface coats after allowing the primer coat is cured for 4-5 hours and keep the surface coat dry for 4-6 hours to achieve the required DFT and allow it be undisturbed for 7 more days to become fully cure. The surface coats should have the following technical properties: a hair line crack bridging upto 1mm; elongation of 100% a per ASTMD 412; tensile strength of 3.5MPa per ASTM D412; adhesion strength of 2MPa as per ASTM D541; The system comes with 5-year waterproofing and 7-year paint performance warrenty from the Company concerned (LMR3)
