Repair of Cistern to avoid ...

Amount

The work includes Chipping and removal of old plaster to identify the old waterproofing surface, active leakage points and construction joints of wall and slab areas for providing waterproofing repairs to stop the leakages. Providing necessary repairs to defective construction joints including grouting with Crystalline cement grout and crystalline repair mortar at all the construction joints where ever it is necessary after cutting U shape groove in wall and slabs, daigonly in wall slab junctions. The opened U shape groove should be stitched in laminating layers after cleaning the surface water before starting application. The material must capable of withstanding Hydrostatic pressure of 16 bar continuous exposure for 7 days by using Catalytic Crystalline Penecrete Mortar and finishing coat of Penetron on all construction joints. Providing crystalline cement grout in all honeycomb areas with Crystalline cement grount and crystalline repair mortar where ever it is necessary after fixing the nozzles of required diameter, 60% depth of the concrete structure at 45` angle, spacing as required at site conditions in zigzag manner in wall by mechanical means before starting the coating application. Supply and application of penetrative up to 1m death and barrier type as per BS 8102, catalyst integral crystalline waterproofing treatment to vertical surface of footings retaining wall raft and liftpit etc. having speed of penetration of 31 Cm in 56 days and resistance to 16 bar hydrostatic water head pressure from positive either negative side surface and capable of reducing Permeability of concrete by more than 91%, compared with control concrete, when tested as per DIN 1048 (after applying 4 cycles of hydrostatic pressure) and permeability co-efficient calculated as per Valenta/Darcy’s formula to be carried out as per the manufacturer`s specifications and as detailed in technical specification, complete. Work shall be carried out with all necessary grouting voids and honeycomb area repairs etc with crystalline repair mortar and primer Material: PENETRON
