Note :- WPC Shall be measured seperately.

Supply only integral water proofing compound of Sika Plastocreat plus or equivalent make in list of makes as approved by GE @ 0.2% by wt of cement consumed

M&L for all junctions points of side wall where CI/GI/PVC pipes are passing through shall be sealed with epoxy putty Sikaguard 694 F(I) or equivalent make in list of makes as approved by GE @ 150gms /Sqm and including after drying putty, wash the slab and sides of sunken portion with water and make it clear and clean.

M&L for providing and fixing 12-16mm dia injection ports non returnable nozzle by drilling, cleaning and sealing holes 50-75 mm deep with fast setting high strength Epoxy putty, solvent free, three component compound based on epoxy resins, graded fillers and thixotropic agents as approved by GE as in beams, columns, slab and parapets as per the technical specifications and manufacturer's instructions complete all as specified and directed.

M&L for grouting of nozzles with low viscous moisture insensitive, High strength, epoxy resin grout as approved by GE with pressure not excedding 2-3 Kgf/Sqcm till the nozzle refuses to take further grout including cutting extra length of the nozzle after the grout hardens and finishes as per the technical specifications and manufacturer's instructions complete all as specified and directed.

M&L for drilling holes at the first joint of masonry wall at ground level horizontally 10mm diameter in masonry structure along the side of the joints at 45 degree so as to cross the brick/block at the intervals spacing in 300 mm depending on extent of rising dampness as per recommendation of Engr-in-charge, cleaning of hole :- Clean the hole by air blower prior to fixing nozzles. Install NRV packer injection packers 10 mm diameter, 10 cm long in the holes and tighten. Fix the packer securely using Sikagard 694 F(I) or equivalent in list of makes and supply and apply of 3 parts, very low viscous elastic polyacrylic injection resin Sika @ Injection 306 or equivalent in list of makes with a versatile and adjustable reaction time having mixed viscosity: 3-11 M pa s at +20 degree C, reaction time : adjustable according to ambient temprature and execution requirement between 8-50 Mins Ph 9-10. Tested as per wissbau No 2002-094- (1A) fuction test with re-injectable hose system. these holes should be drilled until a depth of approx. 5 cm (for a 6cm thick wall) before the end of the wall is reached. Pump Sika or equivalent in list of makes @ injection -306 @ at>20 bar into a behind fissures or into masonry joint which are allowing water to infiltrate into unwanted area if voids is masonry being injected contain insufficient moisture to activate the grout inject a small amount of water prior to injecting the grout when movement stop of sika @injection -306 appears at the next packer move to the next packer and inject. if the dampness is heavy inject similarly at next joint line, pumping of sika injection is to done till chemical comes out from adjacent holes. Cutting of packers :- Cut the packers after completion of grouting without damaging structural elements. Note : consumption of all chemicals is deemed to be included in the quoted rate of the contractor, consumption of chemical per hole may vary from 0.5 kg to 1.5 kg.

M&L for the sunken floor filled with lean concrete 1:5:10, type E2(40 mm graded aggregate) as in sunken portion /padding leveling course providing necessary slope including WPC of approved make @ 200ml per bag of cement/ manufactures instruction on brick/ concrete wall surfaces of any description and complete all as specified and directed. Note :- WPC Shall be measured seperately.
