| Sl. No. | Item Description |
| 1 | Providing and applying 5.3 mm ESD-Epoxy anti-skid foor coating system including surface preparation by cleaning surface from dust dirt, muck moisture and all foreign material and cleaned by mechanical means using mechanical scrubber/grinder, chemical treatment for cleaning oil if required followed by application of primer Nitoprime 25 of Fosroc or equivalent in Sika/Bostik which shall be a two component epoxy based system. The pre packed and factory weighed two components shall be mixed for 3 mins using a low speed drill and applied at 5.5-6.5 m²/Lit @ 200 micron thick. Then providing and applying the screed layer with Nitoflor EU5 of Fosroc or equivalent in Sika/Bostik at minimum thickness of 3000 microns @ 7.5 m²/pack @ 2 mm thickness. The self levelling screed shall consist of a low viscous epoxy system and graded aggregate (Special silica/Filter). The pre-packed components shall be mixed as per the packing ratio and applied. The epoxy underlay shall achieve a minimum compressive strength of 60 N/mm², Flexural Strength of 20 N/mm² and Tensile strength of 10 N/mm² @ 7 days. The underlay shall have nil water absorption when tested as per BS1881 Part 122-1983. |
| 2 | Then over the screed apply copper tape of 100 microns thick and 25 mm width, connected to existing earth pit having spacing 10m both directions, then conductive primer coat Nitoflor SL of Fosroc or equivalent in Sikka/Bostik conductive base coat shall be applied at a thickness of 100 microns and then top coat of 2000 microns- Nitflor SL conductive of Fosroc or equivalent in Sikka/Bostik shall be applied to provide Approx 3 x103- 9x103 Ohms surface resistance. Which shall be supplied in pre-weighed packs and ready to mix and use which will consist of resin, hardner, EPI (colour concentrate) formulated aggregate and carbon fibre+special anti skid silica sand/filter. All these to be mixed in the pre weighed ratio, add EPI colour (colour concentrate) and formulated aggregates+special anti skid silica sand/filter to agitate the mixture by an electrically driven motor and lay the mixture to the thickness of 2000 microns then deareate by using spike roller and to allow to cure for a minimum period of 48 hours before trafficking is commenced. Over top coat demarcation paint with fluorescent will be applied. |
| 3 | M & L for cutting and racking out joints with cutter and cleaning with blower and making sides of joints bitumen free for all joints and sealing the joints with single component polyurethane based sealant Seal N Flex FC of M/s Bostik/Fosroc/Sika, or equivalent and approved by E-in-C"s branch over a coat of N-49 primer of M/s Bostik/Fosroc/Sika or equivalent approved by E-in-C"s Branch, includingbond breaker caulked tightly into the base of sealing groove complete all as per manufacturer"s instructions and as directed by Engr-in-Charge . Make: Bostik/Fosroc/Sika, as approved by E-in-C"s branch |
| 4 | M & L for providing and appyling white, yellow or as required colour shalifloor TC2 HBE @ 0.3 Kg per Sqm, 100 mm width with fluorescent on applied Epoxy SL conductive flooring. |
| 5 | M & L for cutting out existing damaged concrete slab with cutter in proper rectangular, square or triangular shape correction of cracks, edges, repair of potholes and undulations providing and laying of single component self-levelling PU based fast setting elastomeric concrete like ShaliPatch EC/DELPATCH or equivalent as approved by GE, after thorough mixing with and electrically operated paddle stirrer having setting time of 1 to 1½ hour and yield of 1800 Kg/cum with a prior coat polyethylene based single component fast drying primer like ShaliPrime PUM or equivalent applying @ 100 ml/Sqm after cutting the damaged area to proper geometrical shape with min depth of 25mm and cleaning the surface thoroughly with air jet. Make: DALPATCH/STP or equivalent by E-in-C"s branch. |
