"Supply of STP CAT-6 Cable (Shielded Twisted Pair) STP compliant with latestEIA/TIA- 568-B2-1. INSPECTION: RITES"

Providing and applying integral crystalline slurry of hudrophilic in nature for waterproofing treatment to the RCC structures like retaining walls of the basement, water tanks, roof slabs, podiums, reservior, sewage & water treatment plant, tunnels/ subway and bridge deck etc., prepared by mixing in the ration of 5: 2 (5 parts integral crystalline slurry : 2 parts water ) for vertical surfaces and 3 : 1 (3 parts integral crystalline slurry : 1 part water) for horizontal surfaces and applying the same from negative internal side with the help of synthetic fiber brush. The material shall meet the requirements as specified in ACI- as per DIN 1048 and resistant to 16 bar hydrostatic pressure on negative side. The crystalline slurry shall be capable of self-healing of cracks up to a width of 0.50 mm. The work shall be carried out all complete as per specification and the direction of the engineer-in-charge. The product performance shall caryy guaranteed for 10 years against any leakage.

M&L for special treatment of sunken portion of WCs and Bath room as per following stages: Stage 1 :- Demolition of WC including lime concrete and cement concrete coba etc and preparing the surfaces of existing sunken portion of WCs or bath etc with wire brush to remove all loose dirt, oil grease etc . Stage 2:- Providing 10mm thick plaster in CM 1:4 with chemical of Dr. Fixit Pidicrete URP or plaster seal of STP Ltd Stage 3:- Applying Dr Fixit Primseal primer or STP Ltd(and allow to dry for 8 hours) under touch dry condition Stage 4:- Applying two coats of water proofing decorative elastomeric coating system of Dr Fixit Raincoats with DFT 100 Micron or shalicry 215 of STP(The surface after painting one coats shall be allowed to dry of 6 hours before next coats) all as per manufacturer instruction Stage 5:-Again rendering 10mm thick in CM 1:4 mixed with Dr Fixit Pidicrete URP or plaster seal of STP Ltd. Stage 6. All CI joints shall filled with mixture of cement fine sand and plaster seal of STP Ltd or Dr Fixit pidicrete URP. Stage 7:- Making holes in wall and fixing 600mm long 20mm dia GI spout for draining the surplus water if any.
