Water Treatment & STP Tenders

Grading roof for water proofing treatment with water proffing compound Cement concrete 1:2:4 (1 cement : 2 coarse sand : 4 graded stone aggregate 20 mm nominal size)

M&L for water proofing treatment to sunken floors of toilets, laboratories, bath, WCs, kitchen etc as under:- (i) Application of two component acrylic modified cementitious coating :- (a) The surfaces to be applied shall be completely dry and free from containments such as dirt, dust, oil, surface treatments and old coatings. Concrete substrates must be mechanically prepared using abrasive blast cleaning or milling to remove cement laitance existing coating and achieve a gripping profile that is clean, dry and free from laitance and any other from of surface containmation. The installation instruction in manufacturer's published literature shall be strictly complied with, including but not limited to the following:- (b) Chipping out any visible cracks in "V-Groove" pattern as applicable. Cleaning of cracks & filling with SIKA latex SBR 100 putty/Dr. Fixit 302 SBR latex/ perma latex SBR/FOSROC Nitbond SBR latex/Asian paint latex as required. Final cleaning of surface with powder grinder, wire brush, hair brush & vacum pressure. (c) Providing and applying a protection concrete 1:2:4, 50mm thick admixed with plastocrete over the applied water proofing coating on horizontal surfaces.(Admixture: Sikaplastocrete plus/FOSROC/Dr. Fixit/STP/CICO confirming to IS 2645.) (d) Dampen all surface immediately ahead of apllication of acrylic modified cementitious coating of SIKA top seal-107/Brush bomd FOSROC/Dr. Fixit/STP/CICO. (e) Whilst the surface is still damp from saturation (SSD) apply one coat of acrylic modified cementitious coating of SIKA top seal-107/ Brush bond FOSROC/Dr. Fixit/STP/ white first coat is wet.

Providing and applying integral crystalline slurry of hydrophilic 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 ratio 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 ACI212-3R-2010 i.e by reducing permeability of concrete by more than 90% compared with control concrete 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 0.50mm. The work shall be carried out all complete as per specification and the direction of the engineer-in-charge. The product performance shall carry guarantee for 10 years against any leakage.
