Details: Sealing of Cracks (V-groove): Make V-groove of size 15 mm wide and 10 mm deep approximately along the cracks manually using chisel and hammer or by using groove cutting machine, clean the V-groove using air jet and make them dirt & dust free. While fixing the nozzles along the V- grooves, simultaneously seal the V-groove using non-shrink two component epoxy putty to the concrete surface level.The rate shall include cost of all required material, machinery, tool,tackles , all consumables and labour wages etc ., Complete all as per specification and as directed by the Engineer-In-Charge at all heights / lifts and at all locations. Fixing Nozzles for Injection Grouting: Drill holes of 12/14 mm dia along the cracks (V-groove) at an interval of 500 mm c/c for about 50 mm to 80mm deep, clean the holes using air jet and make them dirt & dust free. Fix the PVC nozzles/packers having non-returnable valves for pressure grouting using non-shrink two component epoxy putty . The rate shall inc
