| 1 | Providing & and Injecting Eco friendly, solvent free, CFC, VOC, Halogens and also Phthalate-free, Mountain Grout Ultra which is a low viscosity hydrophobic polyurethane formulation with high elongation properties for sealing leaking cracks or joints where some movement is possible. The system is comprised of a base resin along with an accelerator component. Mountain Grout Accelerator should be used by the experienced installer to manipulate the reaction profile as warranted by job site conditions. Being a hydrophobic formulation, when reacted with minimal amounts of water, the resulting foam will maintain its physical form and not be subject to shrinkage due to wet/dry cycles. When injected into wet cracks, Ultra produces a closed cell foam. The injecting of PU grout should be done with a pressure up to 2 kg/cm2 or as desired .Grouting is to be continued till nozzle refuse to accept further grout by using Mountain Grout Ultra from Green Mountain International or its equivalent approved quality material .Pressure grouting shall be done with heavy pressure pump by injecting the PU grout in sealed nozzles or metal packers for arresting the leakage, seepage water by PU injection gun including all pumping system & machinery till the refusal by allowing properly setting & sealing the nozzles without wasting the injecting materials and making the system complete safe / water tight as required. etc. including working at all heights inclusive of all material, labour, tools, temporary supports for structures, scaffolding, plant and machineries, curing etc. as required for successful completion of work, complete as directed by Engineer in charger Payment shall be made per Lit. of material net utilized during the grouting Operation. wastage of material will not be Considered for the payment.General Pumps as a single component Non-flammable Controllable reaction times Cures inert, non-toxic permanent seal.

| 2 | Providing and fixing Injection Packer of appropriate diameter and length depending on site condition, with high strength steel screw and structured rubber sealing, resistant to injection pressures >300 bar using quick setting cement if required. Drill holes 300 mm to 400 mm from the outer face of finished surface of construction according to the packer diameter diagonally at 45 angle on the side of the crack or joint or honeycombing at 45 angle using a Ferroscanner to avoid hitting the reinforcement including required manpower/ materials, machineries , scaffolding at any height, making working platform on and around the structure etc. as required for successful completion of work complete as directed by E.I.C. Payment of drilling holes shall be made as per No. for steel packers or nozzles provided and sealed in the hole. | 3200.00 | Nos. |
| 3 | Providing and applying a Waterproof, Non- Shrink, Polymer Modified, Trowel Applied, Repair Mortar, SS StructoRep R4 / SS StructoCrete NS manufactured by Assess BuildChem Pvt. Ltd. or its equivalent for use in Waterproofing applications to fill any voids, honeycombs, spalls and surface cracks in horizontal and vertical surfaces to the prepared concrete area for thickness up to 50mm,as per manufacturers specification, at all heights inclusive of all material, labour, tools, temporary supports for structures, scaffolding, plant and machineries, curing etc. as required for successful completion of work, complete as directed by Engineer-in-charger. Payment shall be made per Kg. of material net utilized during the grouting Operation. wastage of material will not be Considered for the payment. | 8900.00 | Kg |
| 4 | Providing & applying Specially Modified, Super Quick Setting, Compound for Use as Water Plug to Stop Running Water Leakages of SS Quick Stop manufactured by Assess BuildChem Pvt. Ltd. or its equivalent for use in Waterproofing applications to fill any voids, honeycombs, spalls and surface cracks in horizontal and vertical surfaces for stopping running water leakages as per manufacturers specification, at all heights inclusive of all material, labour, tools temporary supports for structures, scaffolding, plant and machineries, etc. as required for successful completion of work, complete as directed by Engineer-in-charger. Payment shall be made per Kg. of material net utilized during the grouting Operation. wastage of material will not be Considered for the payment | 4700.00 | Kg |
| 5 | Providing & applying Two component Cementitious Crystalline coating system on the negative side of the structure except floor by using SS - CrystoSeal 2K manufactured by Assess BuildChem Pvt. Ltd. or its equivalent two-component cementitious system, comprising of a powder and a liquid component, which when mixed with water forms a chemically active slurry that functions on the principle of crystallization. The powder should be composed of a cementitious binder, well graded fillers and a combination of active additives. The liquid should be a polymer modifier. Due to its formulation, the active substances in coating penetrates the substrates by osmotic action, hydrates to form insoluble crystals and there by blocks the penetration of Water into the substrate, through capillaries and cracks. The coating should form a breathable (allows water vapour diffusion) cover that forms an integral part of substrates and shows extreme resistance to water ingress, both on the positive as well as negative side. It reacts with any free lime present in the substrate to form denser hydrates, that prevent any movement of water . The work should be carried out as per manufacturers specification, at all heights inclusive of all material, labour, tools temporary supports for structures, scaffolding , plant and machineries, etc. as required for successful completion of work, complete as directed by Engineer-in-charger.Technical Data:SpecificGravity1.6+/-0.05,Consumption~1.6kg/sq.m/mm thickness,Mixing ratioComp1 :100 pbwComp 2:10 pbwWater for brushable slurry:10-15 pbwWater Penetration : Nil up to 3 bar pressurePost Application Curing is mandatory | 1640.00 | Smt |
