The work shall be carried out all complete as per specification and the direction of the EngineerIn-Charge. The product performance shall carry guarantee for 10 years against any leakage For sealing cracks and faulty construction joints, routed out/making U-shape groove size 25x25mm and then primed the area with integral crystalline slurry @0.05kg/running metre and while the surface is tacky filled the groove upto surface with crystalline mortar @1.50kg/ running metre. Once crystalline mortar is touch dry then finally applied two coats of integral crystalline slurry @0.05kg/running metre per coat) is derived from 5 priced inputs for 1.00 meter and works out to ₹547.70 per meter after water charges, GST, CPOH and cess.
