4 The Flexible-Matrix Catalytic In-depth crystalline WATERPROOFING System shall be able to withstand atleast 460 ft. of water head pressure. Both the above characteristics shall be supported with an International Test Report. The Flexible-Matrix Catalytic In-depth crystalline System [offered system : Tamms Hey Di K-11 + SB Flexibilizer, from M/s. Euclid Chemical Co., USA] shall be applied at a minimum coverage rate of on the honeycomb-free, levelled plum PCC before tying reinforcement for the RCC raft and on the retaining wall from the external side.

5 Cost to include base preparation including cleaning and wire-brushing the PCC surface, plugging / grouting any leaking points on the PCC with a specialised fast setting mortar, treating all construction joints, cracks, honeycombs on the RCC Raft and retaining wall by plugging / grouting with a specialised non-shrink cementitious compound, etc., complete with a protective layer of 50 mm thick, M-20 concrete screed (if the system requires) admixed with a integral WATERPROOFING compound and a guarantee for minimum period of 15 years from completion.

6 SQM OR OPTION 2 : APP MODIFIED POLYMERIC BITUMINOUS MEMBRANE SYSTEM :Providing and installing WATERPROOFING treatment with Membrane type WATERPROOFING method in box-type fashion, on the PCC below raft and on the retaining wall from the external side using APP Polymer Modified Bituminous Membrane (offered system : Zetagum / Monogum , from M/s. VALLI ZABBAN , Italy) with UV resistance, underground ground-chemical resistance, high melting points, flexible and elastic with high adhesive strength.

7 The membrane shall be reinforced with a layer of non-woven polyester fabric of minimum 180 g/sqm or composite reinforcement of minimum of 175 g/sqm and reinforced with glass fibre grill of 8 g/sqm. The upper surface is finished with calibrated granules of - 1 mm, pressed mechanically into the bitumen. The under surface is finished with a polyethylene foil of 12 micron thickness. The total membrane thickness is 4 mm and minimum weight to kg/m including coating with compatible primer of bituminous base and torch application with overlap of 70 - 100 mm wherever required.

8 The reinforcement provided shall be able to withstand the traffic flow density and after construction and shall carry a minimum guarantee period of 10 years. Cost to include laying and torching the prefabricated overlap at ends. Cost to include necessary protection to layer either by colour slates / granules / 3 mm thick hard bituboard, as approved by consultants, grouting the construction joints, cracks, honeycombs, etc. SQM PROJECT : bill OF QUANTITY - WATERPROOFING Page 2 Sr. No. Item Description Unit Qty.
